DEADLY EARTHQUAKES STRIKE AT CENTRAL PHILIPPINES
EARTHQUAKE SUMMARY FOR APRIL 22, 2019
Global seismic quiet came to an end today with earthquakes of M 6.1 and 6.4 in the Central Philippines; an M 6.0 in the South Sandwich Islands and moderately large events of M 5.4-5.6 in Vancouver, British Columbia, Canada; off the coast of northern Honshu, Japan and in Oaxaca, Mexico. Seismicity in California also showed a moderate increase at this time with an M 3.9 in the Imperial Valley region of southern California.
A pair of strong earthquakes of M 6.1 and 6.4 hit the Luzon, Central Philippines about 60 km NW of Manila and Samar Island, Leyte today. Initial reports indicated the first of these killed at least 16. Five people died when a five-story supermarket collapsed (pancaked) on the store. Electricity was cut to prevent fires. Many people were crushed beneath collapsing building in the Pampanga Province and at least 24 are still missing. Landslides block roads as boulders rolled down mountain sides and most public transportation was suspended. The second earthquake in Samar was reported to have damaged homes and roadways as well. This event was located about 75 km from Tacloban City, which has a population of about a quarter million. In Samar, at least five houses were destroyed in the city of Catbalogan. Three dams in the Central Philippines sustained damage. No tsunami was expected nor observed with either of these earthquakes.
While the earthquake in Samar was probably triggered by stress redistribution following the Luzon quake, tidal promotion cannot be completely dismissed. The Samar earthquake occurred new local solar noon when tidal stresses maximize. It also occurred at 11N latitude when the sun was directly overhead at local solar noon (subsolar). This enhanced vertical stresses and probably helped promote the second earthquake as noted in previous issues of this report:
"The full moon arrived at 11:12 UT on April 19, 2019. Longitudes which were sub-solar at this time were near 15 East and 165 West. These include areas of central and western Europe in the east and the Aleutian Islands and western Alaska in the West. Other areas which may see enhanced tidal promotion at this time are the Kermadec-Tonga arc north to Samoa. While these regions will experience maximum stress from the tidal alignment, many other areas could see enhanced seismicity in the next five days and a strong earthquake is likely in this time period." (April 19-22, 2019)
NEIC reported major damage in the Luzon quake with intensity up to IX. VIII was reported from Central Luzon at Del Carmen with VII in Bodega, Calangain, Guta, Hermosa, Lubao and VI in San Benito, Irani and San Basilio, Central Luzon and as far as 150 km from the epicenter with intensity up to IV.

An earthquake of M 6.0 also occurred today in the South Sandwich Islands continuing strong seismicity in that area this month which has included events of M 6.5 on April 5 and 9 and M 5.5 on April 16. None of these events have been reported felt in this remote area. Today's event occurred near local solar noon and may have been promoted by high tidal stresses. Forecast 115291 had expected this activity in the South Sandwich Islands around April 18-20.

The strongest earthquake in the U.S. or Canada today was an M 5.5 in the Vancouver Island area of British Columbia, Canada NEIC reported it was lightly felt in Port Hardy, B.C. and in Walnut Grove and Nanaimo, B.C. and as far as Bellingham, Washington. The M 5.5 was preceded about an hour earlier by an M 4.9. These events occurred within about an hour of local solar noon and were probably promoted by high tidal stresses associated with the full moon. The last earthquake within about 150 km of today's epicenter with M>=5.5 in the Vancouver Island region occurred with M 6.5 on October 22, 2018 and prior to that an M 5.5 on March 18, 2016 more that three years ago. Forecast 115209 had expected a moderately large quake was possible in this area in mid-April. This epicenter is at 102 degrees from the M 6.8 in Sulawesi of April 12, the last major earthquake in the world and was probably promoted by concentrated energy from that source.

This event in Oaxaca State was felt with intensity II-III as far as 400 km from the epicenter (NEIC) at Oaxaca, Tlaxcatancingo, Puebla, Tres Marias, Zacamulpa, Mexico City And Naucalpan, Mexico among others. An earthquake of M 4.3 in eastern Oaxaca occurred earlier in the day. This event was reported by NEIC to have been felt with intensity IV in Xadani, Oaxaca and II-III in Huatulco, Pochutta, Oaxaca, Mexico. The M 5.4 is the strongest within about 100 km of this epicenter since an M 5.9 on February 19, 2018, an aftershock of an M 7.2 on February 16, 2018. Forecast 115068 had expected this activity within about 100 km was likely around April 19.

OTHER GLOBAL EARTHQUAKE ACTIVITY
For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

TIDAL STRESSES, OTHER PROMOTERS MAY BRING ENHANCED GLOBAL SEISMICITY
EARTHQUAKE SUMMARY FOR APRIL 21, 2019
The current lull in global seismicity continued today. A geomagnetic storm is on the horizon and two ocean storms show promise to become tropical cyclones. This activity is likely to combine with the full moon tides to promote enhanced seismicity as noted in previous summaries:
"The full moon will arrive at 11:12 UT on April 19, 2019. Longitudes which are sub-solar at this time are near 15 East and 165 West. These include areas of central and western Europe in the east and the Aleutian Islands and western Alaska in the West. Other areas which may see enhanced tidal promotion at this time are the Kermadec-Tonga arc north to Samoa. While these regions will experience maximum stress from the tidal alignment, many other areas could see enhanced seismicity in the next five days and a strong earthquake is likely in this time period." (April 19-22, 2019)
The strongest earthquake in the world today occurred in the Tonga/Fiji zone and was likely promoted by tidal stresses. This event of M 5.4 southeast of the Loyalty Islands was somewhat unusual. The last earthquake of M>=5.4 within about 250 km of this epicenter occurred nearly two years ago as an M 5.7 on July 8, 2017. A strong M 7.2 hit the area about 200 km to the west on August 12, 2016. Forecast 115264 had expected regional seismicity in the Loyalty Islands in mid April.

An earthquake of M 4.5 continued the activity in the Mayotte region east of Africa today. The current Mayotte series began a year ago on May 13, 2018i with an M 5.1. The last event of M>=4.5 in the area was an M 5.0 on April 5, 2019. Forecast 115248 had expected activity in the region was likely around April 22. A new tropical cyclone to the northeast of this may have helped promote today's activity as noted in this summary:
"A tropical cyclone may be forming in the area north of Madagascar. This system is currently located near 10S 51E with winds up to 30 kts and moving westward at 6 kts. The area of Mayotte may be active as this storm approaches." (April 21-22, 2019)
NEIC reported this earthquake of M 4.5 in Mayotte was felt with intensity II-III in the area(s) of Mamoudzou, Mayotte.

The strongest earthquakes in the U.S. or Canada today occurred in Central Alaska and in Central California with M 3.4-3.5. The M 3.4 in Central Alaska
was felt lightly in the epicentral area. It is the strongest event within about 150 km of this epicenter since an M 3.7 on January 17, 2019 and prior to that an M 3.6 on November 30, 2018. These occurred about 150 km north of today's epicenter. Forecast 115234 had expected today's activity within about 25 km of the epicenter was likely around April 19.

The M 3.5 in Central California was felt widely in the area. NEIC reported this earthquake of M 3.5 in Central California was felt with intensity IV in Carmel Valley, California and II-III in the area(s) of California at Gonzales, Soledad, Paicines, Hollister, Salinas, San Juan Bautista, Greenfield. This is the strongest earthquake within about 50 km of this epicenter in nearly half a year - since an M 3.6 and 4.1 on November 2, 2018. Events of M 3.5 hit the area on November 10, 2018, an aftershock of the November 2 event and with M 3.8 on October 5, 2018, a foreshock, the only such events in the past year. Forecast 115100 had expected today's event within about 25 km of this epicenter was likely in mid-April.

OTHER GLOBAL EARTHQUAKE ACTIVITY
For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

ELAXED SEISMICITY; QUIET DAY
EARTHQUAKE SUMMARY FOR APRIL 19, 2019
Global seismicity was quiet today. There were no significant earthquakes recorded in the Western Hemisphere and only a few of M 5.0-5.2, mostly in the Solomon Islands and southwest Pacific in the Eastern Hemisphere. While the full moon arrived today, with the lack of ocean storm and solar and geomagnetic conditions at very quiet levels, the tidal stresses may not be sufficient to help promote strong seismicity at this time. The tidal forecast had read:
"The full moon will arrive at 11:12 UT on April 19, 2019. Longitudes which are sub-solar at this time are near 15 East and 165 West. These include areas of central and western Europe in the east and the Aleutian Islands and western Alaska in the West. Other areas which may see enhanced tidal promotion at this time are the Kermadec-Tonga arc north to Samoa. While these regions will experience maximum stress from the tidal alignment, many other areas could see enhanced seismicity in the next five days and a strong earthquake is likely in this time period." (April 19-21, 2019)
The strongest earthquake of the day was an M 5.2-5.3 in Mindanao, Philippines. It was not reported felt in the epicentral area of Mindanao. Forecast 115022 had expected this event within about 150 km of the epicenter was likely around April 19.

STRONG QUAKE SOUTH OF AUSTRALIA
EARTHQUAKE SUMMARY FOR APRIL 18, 2019
The strongest earthquake in the world today was an M 6.5 in the Western Antarctic-Indian Ridge south of Australia. It was not reported felt in this remote area. This is the largest earthquake on the Western Indian-Antarctic Ridge within about 300 km of this epicenter since an M 6.6 on June 11, 2000, the only other such event in the area in at least 30 years. Forecast 115288 had expected activity on the Ridge was likely around April 21.

The largest earthquake in the U.S. or Canada today was an M 3.4 in Hawaii. NEIC reported this earthquake of M 3.4 in Hawaii was felt with intensity II-III in the area(s) of Kailua Kona, Waikoloa, Kamuela, Holualoa, Dealakekua, Honaunau, Captain Cook, Naalehu and Kailua, Hawaii. This is the strongest tectonic earthquake in Hawaii since an M 5.2-5.3 occurred several days ago on April 14, 2019 and prior to that an M 3.4 on March 31, 2019. It may have been promoted by tidal effects associated with the full moon as it occurred near local solar noon but is probably an aftershock of the April 14 event as it occurred at the same epicenter. Forecast 115056 had expected this activity was likely around April 15. The tidal forecast had noted maximum tides near the longitude of Hawaii at this time as:
"The full moon will arrive at 11:12 UT on April 19, 2019. Longitudes which are sub-solar at this time are near 15 East and 165 West. These include areas of central and western Europe in the east and the Aleutian Islands and western Alaska in the West. Other areas which may see enhanced tidal promotion at this time are the Kermadec-Tonga arc north to Samoa. While these regions will experience maximum stress from the tidal alignment, many other areas could see enhanced seismicity in the next five days and a strong earthquake is likely in this time period." (April 19-21, 2019)

Unusual earthquakes which may have been promoted by the full moon today included
an M 4.3 in South Korea; an M 4.5 in the DR Congo and an M 3.7 in Sarawak, Indonesia. The events in the Congo and in South Korea occurred near local solar noon, a time when tidal stresses with full moon maximize. Forecast 115033 had expected a moderate quake in the Congo region within about 200 km of today's epicenter in mid-April.

OTHER GLOBAL EARTHQUAKE ACTIVITY
For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

STRONG QUAKE RATTLES TAIWAN
EARTHQUAKE SUMMARY FOR APRIL 17, 2019
A strong earthquake of M 6.1 shook most of Taiwan today. High-rise buildings in Taipei swayed during the quake. NEIC reported maximum intensit VI in Hualien, Taipei, and Miaoli and IV in Ilan, Taichung with lesser shaking in Hsinchu Counties, Taiwan. CWB reported this earthquake was felt with intensity VII in Hualien; V in Nantou, Yilan, Taichung, Taipei; IV in Taoyuan, Hsnichu, Miaoli, Changhua; III in Chiayi, Yunlin, Taitung; II in Kaohsiung, Tainan and Penghu and I in Pingtung Counties, Taiwan. The M 4.1 aftershock was felt with intensity V in Hualien; III in Nantou and II in Taichung and Yilan Counties, Taiwan. More than a dozen people were reported injured in this earthquake which stopped public transportation. Two hikers were injured by rock slides and at least 15 were injured by falling debris in the area of Taipei. The China Earthquake Networks Center gave the event M 6.7. Schools were closed and some roads were shut down for inspection. At least two building were evacuated due to structural damage. Today's M 6.1 occurred within about an hour of local solar noon when Taiwan was near the sub-solar point on the earth (the point where the sun is directly overhead at local solar noon). It was probably promoted by strong tidal stresses associated with the full moon which occurs tomorrow. These maximize near this hour. A moderate foreshock hit the same epicenter on April 9, 2019 following a series of moderate regional events in early April. Today's event of M 6.1 is the strongest in Taiwan since an M 6.4 on February 6, 2018 – that followed an M 6.1 on February 4, 2018, earthquakes which occurred about 25 km north of today's epicenter. These were the largest in Taiwan since February 5, 2016 when an M 6.4 hit the area southwest of today's activity. Forecast 115091 had expected today's event within about 50 km of the epicenter was likely around April 18.

An earthquake of M 5.6 in Central Chile preceded the M 6.1 in Taiwan by about an hour. NEIC reported it was felt with intensity V in Coquimbo; IV in La Serena and Vicuna and II-III in Salamanca, Villa Alemana, Lampa and Santiago, Chile. CSN reported this earthquake was felt with intensity VI in Coquimbo at La Higuera, La Serena; V in Monte Patria, Ovalle, Paiguano, Vicuna; IV in Punitaqui, Salamanca; Canela, Combarbala, Coquimbo; III in Illapel and Andacollo; Atacama with V in Freirina, Huasco and Vallenar IV in Alto del Carmen, Copiapo and Tierra Amarilla and III in Caldera, Chile. This event occurred within less than an hour of local solar midnight and may have been promoted by stresses associated with the full moon alignment which maximizes on April 19. Two events of M>=5.6 have occurred within about 200 km of today's epicenter in the past year - an M 5.7 on March 7, 2019 and an M 6.7 on January 20, 2019. Forecast 115262 had expected today's earthquake was likely within about 50 km of this epicenter around April 19.

The strongest earthquake in the U.S. or Canada today was an M 4.9 in the Fox Islands, Aleutians, Alaska. As it occurred within a few degrees longitude of the maximum tidal stresses associated with the upcoming full moon it may have been promoted by that alignment as noted in this summary:
"The full moon will arrive at 11:12 UT on April 19, 2019. Longitudes which are sub-solar at this time are near 15 East and 165 West. These include areas of central and western Europe in the east and the Aleutian Islands and western Alaska in the West. Other areas which may see enhanced tidal promotion at this time are the Kermadec-Tonga arc north to Samoa. While these regions will experience maximum stress from the tidal alignment, many other areas could see enhanced seismicity in the next five days and a strong earthquake is likely in this time period." (April 17-18, 2019)
Two earthquakes of M>=4.9 have occurred within the Fox Islands within about 150 km of this epicenter in the past 1.5 years - an M 5.1 on January 28, 2018 more than a year ago and an M 4.9 on December 10, 2017. The last such event of significantly larger magnitude was an M 5.3 on August 9, 2017. Forecast 116212 had expected a moderate earthquake in this area around April 17.

OTHER GLOBAL EARTHQUAKE ACTIVITY
For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

MODERATE QUAKES HIT SOUTHERN OCEAN AREAS
EARTHQUAKE SUMMARY FOR APRIL 16, 2019
A series of moderate earthquakes of M 5.5-5.8 hit across the Southern Oceans today. The strongest of these were a series in the central Kermadec Islands of New Zealand (M 5.5, 5.7, 5.8) An M 5.7 also occurred on the opposite side of the world in the southern Atlantic near Tristan da Cunha (M 5.7) and to the south of this in the South Sandwich Islands (M 5.5).
The strongest of the activity in the southern oceans today was a series of moderately large events in the Kermadec Islands of northern New Zealand of M 5.0, 5.5, 5.7 and 5.8. This is a sparsely populated region and earthquakes are seldom reported felt by the local population. A series of moderately large to large quakes has hit the area in recent week, the largest of which was an M 6.4 on March 6, 2019. Forecast 115282 had expected today's activity was likely around April 18.

The earthquake in Tristan da Cunha area of the South Atlantic was also not felt in this remote area. It is the strongest earthquake within about 300 km of this epicenter since an M 5.7 on July 2, 2015. That event was an aftershock of the strongest quake in the area in at least 30 years - an M 7.0 on June 17, 2015.

The M 5.5 in the eastern South Sandwich Islands continued strong seismicity in that area during the current month. This was not felt in this remote area. It is the strongest earthquake within about 100 km of this epicenter since an M 5.7 on December 10, 2015. An M 6.5 hit about 100 km west of this on April 9, 2019. Today's event is probably a regional aftershock of the M 6.5. Forecast 115293 had expected activity in this area was likely with magnitude up to M 5.5 around April 18.

OTHER GLOBAL EARTHQUAKE ACTIVITY
For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

NORTHERN CALIFORNIA ACTIVE
EARTHQUAKE SUMMARY FOR APRIL 15, 2019
A pair of moderate earthquakes occurred in northern California today - an M 4.1 in the Geysers area north of San Francisco and an M 4.2 and foreshocks in the Bishop/Mammoth Lakes area near the central Nevada border. This summary has previously argued that seismicity in California peaks in mid-April to early May and this appears to confirm that analysis.
An M 4.2 was widely felt in the Mammoth Lakes region of central California today. NEIC reported intensity II-III in Bishop, Mammoth Lakes, Shaver Lake, Auberry, Squaw Valley, Yosemite and El Portal, California. An M 3.4 foreshock two minutes earlier was felt with intensity III in Bishop. Smaller foreshocks earlier in the day were also felt lightly in Bishop, California. The last earthquake in the Bishop/Mammoth Lakes region of M>=4.2 occurred on December 28, 2016 when an M 5.7 about 100 km northwest of today's event was followed by a series of aftershocks of M 5.6 and 5.7. The last such event in the Bishop area occurred more than three years ato on February 16, 2016. Forecasts 115095 and 115098 had expected this activity was likely around April 13.

OTHER GLOBAL EARTHQUAKE ACTIVITY
For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

MODERATE EVENTS IN NORTHERN PHIIPPINES; RAT ISLANDS, ALEUTIANS
EARTHQUAKE SUMMARY FOR APRIL 14, 2019
It was a relatively quiet day in global seismicity. The strongest earthquakes were of M 5.2-5.3 and occurred in the northern Philippines and in the Rat Islands, Aleutians, Alaska. PHIVOLCS reported the earthquake in the northern Philippines was felt with intensity IV in Calayan, Cagayan, III in Pasuquin, Pagudpud, Bangui, Adams and Laoag, Ilocos Norte and II in Sinait, Ilocos Sur; Bacarra, Currimao, Badoc and Burgos, Ilocos, Norte, Philippines
An event of M 5.6 hit about 100 km southwest of today's epicenter on March 2, 2019 and an M 5.5 occurred at today's epicenter on January 24, 2019. Today's event is the strongest aftershock to date of the January event. Forecasts 115060 and 115090 had expected today's activity was likly in mid-April.

The strongest earthquake in the U.S., Canada or the world today was an M 5.3 in the Rat Islands, Aleutians, Alaska. It was not reported felt in this remote area. The last earthquake within about 200 km of this epicenter in the Rat Islands with M>=5.3 occurred on April 2, 2019 with M 6.4 and prior to that an M 6.6 on October 8, 2017. Today's event is probably an aftershock of the April 2 M 6.4. Forecast 114938 had expected today's event within about 10 km of the epicenter was likely around April 11. This epicenter is at 101 degrees from the M 7.5 in Ecuador of February 22, 2019 and may have been promoted by concentrated energy from that event.

OTHER GLOBAL EARTHQUAKE ACTIVITY
For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range. This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.
