GREAT QUAKE SHAKES NORTH-CENTRAL PERU

 

EARTHQUAKE SUMMARY FOR MAY 25, 2019

 

The strongest earthquake in the world since an M 8.2 in the Fiji Islands on August 19, 2018 - a great quake of M 8.0 shook areas of north-central Peru today. NEIC reported it was felt with intensity IX (damage) in Peru at Yurimaguas, Loreto; VIII in Requena; IV in Tarapoto,Saquena,; V in Chachaoyas, Pucallpa, Iquitos and IV in Cajabamba and Cajamarca, Peru and in Cruzeiro do Sol, Acre, Brazil. Initial reports and data on the internet indicate this earthquake was damaging in the area of Yurimaguas, a town of more than 60,000 where there was considerable damage and where many buildings collapsed. This is in the Amazon area of Peru, an area of sparse population. Damage was also mitigated by the intermediate depth (100 km) of this event. This is the first shallow or intermediate quake in the world of this size,  howver since an M 8.1 on September 8, 2017 in Chiapas/Oaxaca, Mexico

 

The M 8.0 was preceded earlier in the day by an M 4.7 upslope in the Peru subduction zone. That event was felt with intensity II-III in Peru at Huanchanco and Trujillo, La Libertad and Chimbote, Ancash, Peru.

 

In the preceding issue of this summary it had been noted that a possible outer-rise earthquake had occurred up the subduction zone off the coast of northern Peru.

 

"An unusual earthquake of M 4.4 also occurred west of northern Peru today. While it was not reported felt in the region, This earthquake is the strongest within  about 100 km of this epicenter since several of M 4.4-4.5 on October 10, 2018. It is located on the outer rise of the subduction plate and may be an outer-rise event indicating a strong upcoming earthquake in the region of Northern Peru. This summary discussed outer-rise earthquakes in the previous summary in relation to an M 6.1 in the Andreanof Islands" (May 24-25, 2019)

 

The antipode of today's Peruvian quake is located at 6N 105E west of Sumatra,

Indonesia. There had been some indication over the past several days of unusual activity in this area but this had not been confirmed. This area is generall quiet in a seismic sense. No earthquakes of M>=7.9 have previously been located in north-central Peru within about 300 km of today's epicenter. Forecast 116133 had expected activity within about 50-100 km of this epicenter was likely around May 27.

The strongest earthquake in the U.S. or Canada today was an M 4.0 off the coast of Oregon. The last earthquake of M>=4 within about 100 km of this epicenter was an M 4.7 on April 10, 2019 and an M 4.2 on February 12, 2019. The only other such event in the region since November, 2018 was an M4.5 on January 27, 2019. Forecast 116255 had expected today's event was likely within about 50 km of this epicenter at the end of May.

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.
