MODERATELY STRONG QUAKE IN NEW GUINEA

 

EARTHQUAKE SUMMARY FOR JANUARY 14, 2018

 

The strongest earthquake in the world today occurred in New Guinea with M 5.5. NEIC reported it was felt with intensity II-III in Papua New Guinea in Madang, Kainantu, Eastern Highlands, Wewak, East Sepik and Lae, Morobe, Papua New Guinea. Like earthquakes of M 7.1 in Southern Peru early on January 14 and a pair of moderate quakes in the Manila, Philippines area of M 5.2 and 5.0 late on January 14, this epicenter in New Guinea lies near the geomagnetic equator and may have been promoted by the geomagnetic storm early on the morning of January 14, the strongest in nearly a month. This event may also have been promoted by strong tidal stresses with the new moon which were expected to reach maximum strength at this longitude as previously noted in this summary:

 

"The new moon will arrive at 02:17 UT on January 17. Longitudes experiencing maximum tidal stress at this time are near 35W and 145E longitudes. These are similar  to those of the new moon of January 2 which arrived at 02:24 UT. The same areas are likely to experience maximum stress with the new moon. These were noted in previous issues as:

 

"The full moon will arrived on January 2, 2018 at 02:24 UT. This is a supermoon with the moon at its closest  point in its orbit. Tidal effects are likely to be about 30% larger than with a normal full moon. Longitudes experiencing maximum tidal stresses at this time center about 20 degrees around 37W and 143E and include the mid-Atlantic and the east Pacific rim including New Guinea north to Honshu, Japan. These are most likely to see a strong tidally triggered earthquake in the next six days but tidal triggering is possible in many areas and is not limited to these longitudes." (January 2, 2018)" (January 13-14, 2018)

 

The last earthquake with M>=5.6 within about 200 km of this epicenter occurred on November 7, 2017 (M 6.5) and June 2, 2017 (M 5.9), the only such events  in the area in nearly two years. An M 6.1 hit the region on April 1, 2016, the strongest at that time since December, 2014.  Forecast 113564 had expected this event within about 100 km of the epicenter was likely around January 13.

The M 7.1 in Southern Peru early on January 14 occurred with the strongest geomagnetic storm since December 17, nearly a month. The KP (3-hour average) reached 5 at 0300 to 0600 UT for the first time since December 17. The earthquake in Peru occurred on the geomagnetic equator in an area commonly triggered by strongly changing geomagnetic conditions. It is likely that this quake was promoted by the geomagnetic storm which preceded and accompanied it.

 

CSN reported this earthquake was felt with intensity IV in  Arica, Codpa, Cuya, III Pocon Chile, Huara, La Tirana; II Camina, Felt in Chile at Arica, Parinacota and Tarapaca. Forecast 113734 expected this earthquake within about 50 km of the epicenter was likely around January 16.

Two moderate earthquakes of M 5.2 and 4.9 also shook central Philippines today.

The M 5.1 was reported by NEIC to have been felt with intensity II-III in Southern Tagalog at Sabang, Santa Clara, Tagaytay, Lipa, San Pedro, Kanluran, Santa Rosa, Binan, Pinamalayan, Bacoor, Manila, Tanza, Olongapo and Gapan, in Central Luzon. A foreshock of M 4.9 was felt with intensity II in Bacoor, Southern Tagalog, Philippines. PHIVOLCS reported the M 5.0 was felt with intensity IV in Abra de Ilog, Occidental Mindoro; III in Sablayan, Occidental Mindoro; II in Pola, Oriental Mindoro; Quezon City; Pasay City; Malolos, Bulacan and I in Coron, Palawan, Philippines. The M 5.2 was felt with intensity IV in Paluan and Mamburao, Occiden tal Mindoro; III in Quezon City, Tagaytay City; II in Manila; Calatagan Batangas and I in Nasugbu, Batangas, Philippines.

These earthquakes occurred within about 30 minutes of local solar midnight, a time when tidal stresses are maximized. It also occurred in combination with the strongest geomagnetic storm in the past month. As this epicenter, like that in southern Chile is located at the geomagnetic equator, it is likely that it was promoted by this geomagnetic storm. These epicenters are located at 143 degrees from the event north of Honduras of January 10 and had been expected in previous issues of this summary as.

 

"The two major distances where seismic energy is concentrated following major earthquakes are about 100-108 degrees and 142-146 degrees. Some seismic areas at these distances from Honduras include Myanmar, the Philippines, and western New Guinea at 144 degrees and North Island, New Zealand, Tonga-Fiji, Iran-Iraq and eastern Turkey and Hokkaido and the southern Kuril Islands in  the 103 degree range. These are areas where strong earthquakes may be triggered in the next several weeks. The timing of this series within about an hour of  local solar noon suggests a contribution to the triggering of these events came from high tidal stresses which maximize near this hour."

The strongest earthquake in the U.S. or Canada today was an M 4.5 reported by  Earthquakes Canada near Port Hardy in the Vancouver Island area. Earthquakes Canada also reported an M 4.2 foreshock. No damage was reported and none was expected. The last earthquake of M>=4.5 in this region of Canada was an M 4.7 on November 21, 2017. Earthquakes in the area often follow strong nor'easters such as occurred last week. Forecast 113696 expected this event within about 50 km of these epicenters was likely around January 15.

The largest earthquake in the U.S. today was an M 3.7 in Southern California. This is north of the Landers region where a major quake hit in 1992 and another quake is considered possible in this region. The area may be reaching high stress levels again. The M 3.7 occurred within about 30 minutes of local solar noon and was probably promoted by high tidal stresses associated with the upcoming new moon. The last earthquake within about 50 km of this epicenter with M>=3.7 occurred on February 23, 2016 nearly two years ago with M 4.1. Forecast 113644 had expected this event was likely within about 10 km of this epicenter around January 17.  Southern California is currently experiencing large mud slides which have been deadly. A moderate quake in the area at this time would exacerbate this problem. Moderate to strong earthquakes in Southern California are not uncommon in mid-January and may be promoted by tropical cyclones in the southern Indian Ocean along with seasonal regional weather patterns. The current series of moderate quakes in California is expected to continue. Portions of  the State are at distances from the M 7.1 in Peru today where seismic activity is likely to be promoted from that source.

 

NEIC reported this earthquake of M 3.7 in Southern California was felt with intensity II-III in the area(s) of Ludlow, Landers, Apple Valley and Hesperia, California.

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 STRIKES SOUTHERN PERU

 

EARTHQUAKE SUMMARY FOR JANUARY 13, 2018

 

A major earthquake of M 7.1 hit the area of south-Central Peru today. It caused major damage at Acari, Arequipa where intensity IX was reported by NEIC.  Damage at intensity VII was also reported from Nazca, Ica, Peru with intensity VI at Coracora, Ayacucho and Vista Alegre, Ica, Peru and within about 200 km of the epicenter. Shaking at IV-V levels was relt in Ica, at Ica, Los Aquijes, Santiago, Puquio; in Arequipa at Arequipa about 350 km from the epicenter; in the Lima Provinces at Quilmana, Mala, Chilca, Chosica. Lesser shaking of intensity II-III was felt within about 500 km of the epicenter including at Ayacucho, Chincha Alta, Mollendo, San Vicente de Canete, Cusco, Matucana, Nicolas de Pierola, San Luis, Santa Maria, Lima. It was also felt in Arica and Tarapaca, Chile with light intensity around 600 km from the epicenter. It is likely this earthquake was promoted by tidal stresses associated with the upcoming new moon as well as by stress redistribution following the M 7.6 north of Honduras on January 10. The last earthquake of M>=7.1 in southern Peru within  about 300 km of this epicenter occurred on August 15, 2007 more than 10 years

ago with M 8.0. Other events of M>=7.1 occurred June 23, 2001 (M 8.4) and November 12, 1996 (M 7.7). Forecast 113734 had expected a moderate earthquake within about 50 km of this event was likely around January 16.

The second largest earthquake of the day was an M 5.4 in Hindu Kush, Afghanistan. This event occurred within about an minute following the quake in Chile. The timing is suspicious but classical seismic energy from Chile would not have had time to help promote the Hindu Kush earthquake. It is possible that an unknown external stress at this time helped promote both earthquakes, as well as an unusual M 4.0 at the same time in Hungary. The event in Hindu Kush was lightly felt throughout the area. The last event of M>=5.4 in Hindu Kush within about 200 km of this epicenter was an M 6.6 on April 10, 2016. Forecast 113624 had expected this earthquake within about 50 km of the epicenter was likely around January 17. This earthquake is located at 143 degrees from the M 7.1 in Peru less than a minute earlier, a distance where triggering is considered likely. But the relation between these two earthquakes remains unclear. It is more likely that this event was promoted by seismic energy from the Honduras earthquake as it occurred at 120 degrees (node 3) from that event.

Activity at nodal or triggering distances from Peru and Honduras occurred as moderate quakes in Hindu Kush (144 degrees from Peru and 120 - node 3 – from Honduras); Myanmar (144 degrees); Ceram, Indonesia (146 degrees); Hungary (103 degrees from Peru); Fiji/Tonga (103 degrees from Honduras). 

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.
