MODERATELY STRONG NOON QUAKE HITS FIJI

 

EARTHQUAKE SUMMARY FOR JUNE 26, 2017

 

An earthquake pair of M 5.3 and M 5.8 hit the region of Fiji today within minutes of local solar noon. These are probably tidally promoted seismicity as high tidal stresses occur at local noon and midnight. These are not aftershock of the M 6.2 in Fiji yesterday as they occurred about 500 km south of that epicenter. They were not reported felt in the remote epicentral area. The last earthquake with M>=5.8 within about 250 km of these epicenters was an M 6.1 on June 17, 2017 and these are probably aftershocks of that event. An M 6.9 occurred on February 24, 2017. Forecast 108549 had expected this activity within about 100 km of these epicenters was likely around June 27.

The strongest earthquakes in the U.S. or Canada today occurred along the northern border of California and Nevada with M 4.0 and 4.1. These were part of a strong swarm in the region which occurred within an hour of local solar midnight and may have been promoted by high tidal stresses which maximize at this hour. NEIC reported maximum intensity V in Truckee, California and IV in Norden, Dutch Flat, Glenbrook, California. Lesser shaking with intensity II-III was reported felt up to 140 km from the epicenter in Sacramento as well as in Sierraville, Soda Springs, Loyalton, Carnelian Bay, Kings Beach, Tahoe Vista, Tahoe City, Incline Village, Alta, Tahoma, Forest Hill, Nevada City, Grass Valley, Colfax, Georgetown, South Lake Tahoe, Rough and Ready, Pollock Pines, Quincy, Applegate, Meadow Vista, Garden Valley, Penn Valley, Cook, Camino, Lotus, Placerville, Newcastle, Somerset, Rescue, Pioneer, Lincoln, El Dorado Hills, Rocklin, Granite Bay, Shingle Springs, Folsom, Orangevale, Fair Oaks, Yuba City, Rancho Cordova, Chico, and in Nevada at Reno, Glenbrook, Sparks, Gardnerville.

 

No major damage was reported. The last earthquake within about 50 km of these epicenters with M>=4.1 occurred on October 27, 2011 with M 4.7-4.9 and prior to that on December 25, 2008 with M 4.5. Forecast 108391 had expected this activity was likely around June 29 about 30 km northwest of these epicenters.

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 EARTHQUAKE SHAKES TONGA/FIJI

 

EARTHQUAKE SUMMARY FOR JUNE 25, 2017

 

A strong (M 6.2) earthquake hit the region of Fiji today. It was reported by  NEIC to have been felt in Tonga at Tofoa-Koloua, Tongatapu and in Central Suva, Fiji Islands. The last earthquake of larger magnitude in the Fiji region within about 250 km of today's epicenter was an M 7.0 on January 3, 2017. This is probably an aftershock of that event. Forecast 108534 had expected this event was likely between June 23 and 28. This event is a right angle quake from Guatemala occurring at the fourth node (90 degrees) from the earthquakes of M 6.8-7.0 of June 14 and 22, 2017. When a regional foreshock occurred on June 19 of M 5.8, this summary noted the relation with Guatemala as:

 

"... Fiji Islands was likely around June 19. This epicenter is at the fourth node (90 degrees) from the quake in Guatemala of June 14 and was probably promoted from that source." (June 19-20, 2017)

A moderate earthquake of M 5.4 in the Hindu Kush region of Afghanistan was the second largest event of the day. This is the strongest earthquake in Afghanistan during the year 2017. The last event of larger magnitude in the Hindu Kush area within about 150 km of today's epicenter was an M 5.4 one year ago on June 23, 2016. The last of larger magnitude was an M 6.6 on April 10, 2016.  NEIC reported this earthquake of M 5.4 in Hindu Kush, Afghanistan was felt with intensity IV in Kabul,  Afghanistan and II-III in the area(s) of Afghanistan at Mahmoud Raqui, Jalal Abad, Mir Bacheh Kowt and in at Islamabad, Pakistan. Forecast 108396 had expected this earthquake was likely within about 50 km of this epicenter around June 23. 

 

Like recent strong earthquakes in the Guatemala and Chiapas, Mexico area, this epicenter is located at 102-104 degrees from the Vanuatu quake of M 6.8 on May 9. Concentrated seismic energy at this distance following large earthquakes can lead to a period of enhanced seismicity at this distance. Another unusual quake today at this distance from Vanuatu was an M 4.9 in the Los Lagos region of Chile/Argentina.

An earthquake of M 4.4 north of Iceland today appears to have been promoted by strong tidal stresses associated with the new moon of June 24. This event is the farthest north of event in the region of Iceland with M>=4.4 since an earthquake of M 4.4 on September 1, 2015 and prior to that an M 5.0 on June 16, 2014. A strong swarm hit the region on July 15, 2013 as well. Forecast 108518 had expected this was likely within about 200 km of this epicenter around June 23. The tidally associated seismicity forecast for this period had noted that events near this longitude in the Atlantic region were especially vulnerable to enhancement by tidal stresses at this time:

 

 

"The new moon arrived on June 24 at 02:31 UT. Areas which were sub-solar at this time lie within about 20 degrees longitude of 145 East longitude while those anti-solar areas are near 35 West longitude. These include the mid-Atlantic Ocean region in the west and Japan and the western Pacific subduction zone in the east. These regions are most likely to see a strong to major earthquake during the period June 22-26 but tidal enhancement of seismicity can occur in many tectonic settings and is most likely near local solar midnight and noon at this time." (June 21-14, 2017)

 

This epicenter is at the fifth node from Guatemala (72 degrees) and was probably promoted by energy from the quakes of M 6.8-7.0 on June 14 and 22.

On the opposite side of the world, and probably also affected by high tidal stresses with the new moon, elevated seismicity continued in the region of Japan. An M 4.5 occurred off the coast of northern Honshu but was not reported by NEIC to have been felt. Forecast 108413 had expected this event within about 25 km of the epicenter was likely around June 23. This epicenter is at 106 degrees from the recent strong quakes of M 6.8-7.0 in Guatemala and was probably promoted from those sources.

A moderate quake of M 4.6 also occurred in Guam today. This event had been expected as a potential tropical storm moved through the area today as:

 

"A tropical storm may be forming near Guam. This system is currently located near 13.7N 145E over Guam. It could form into a stronger storm. Seismicity in the region of Guam has been high the past two days with this storm and could still see another moderate associated earthquake in the next three days." (June 24-25, 2017)

 

Forecast 108354 had expected today's event was likely around June 24 in the region of Guam.

The largest earthquake in the U.S. or Canada today was an M 3.5 in the region of Southern California near Big Bear City. It was reported widely felt in the area east of Los Angeles, California.  NEIC reported this earthquake of M 3.5 in Southern California was felt with intensity II-III in the area(s) of Banning, Forest Falls, Yucaipa, Beaumont, Cabazon, Angelus Oaks, White Water, San Jacinto, Redlands, Big Bear Lake, Idyllwild, Nuevo, Morongo Valley, Big Bear City, Hemet, Homeland, Moreno Valley, Palm Springs, San Bernardino, Grand Terrace, Sun City, Riverside, and in general within about 50 km of the epicenter.  The last earthquake of M>=3.5 within about 50 km of this epicenter occurred on June 18, 2017 with M 3.5. Quakes of M 3.4-3.6 also hit the area on May 15 and March 18, 2017 but  the last of significantly larger magnitude in the region was an M 3.9 on December 28, 2016. Forecast 108422 had expected this event within about 10 km of this epicenter was likely around June 26.

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.
