STRONG QUAKE FELT IN NEW GUINEA MAY AFFECT CALIFORNIA SEISMICITY

 

EARTHQUAKE SUMMARY FOR JANUARY 18, 2020

 

The strongest earthquake in the world today was an M 6.0-6.1 in northern New Guinea. NEIC reported it was felt with intensity IV in Aberpura, Papua New Guinea, Indonesia. Strong earthquakes in this area can affect seismicity in the Los Angeles area of California as it is located at 103 degrees from this. Major quakes in New Guinea are often followed by moderate to strong quakes in southern California about a month later. Major quakes in California often occur in January and February (for example San Fernando - February 9, 1971 and Northridge - January 16, 1994). Today's event is not large enough to trigger this large an event but may be precursory to larger regional events in New Guinea.

 

The M 6.0 in New Guinea was followed a series of moderate aftershocks. The M 6.0

in the strongest within about 200 km of this epicenter since an M 6.1 on June 24 and an M 6.3 on June 19, 2019 several weeks before the M 7.1 in Ridgecrest, California. The last earthquake of significantly larger magnitude in this area of New Guinea was an M 7.0 on July 27, 2015. Forecast 121199 had expected today's event within about 100 km of the epicenter was likely around January 15.

An earthquake of M 2.6 in southern California near Grapevine followed the New Guinea quake of M 6.1 about 37 minutes after that event. This region of Southern California has been hypothesized by some to be the likely site of the next Northridge type event in the region. The SS- and SSS-phases from New Guinea were in the area when this event occurred and may have helped trigger it. This summary has noted the tendency for Northridge-type events in the region to recur with intervent times around 23-26 years. This includes an M 6.7 on December 25, 1899; an M 6.3 on July 23, 1923; an M 6.3 on March 15, 1946; an M 6.7 on February 9, 1971 and the Northridge event of M 6.7 on January 17, 1994. As it has been 26 years since the Northridge quake, such an event may be past due. The effect of the M 7.1 in Ridgecrest, California of July 6, 2019, however, on the seismicity of the Los Angeles area is uncertain and could delay or encourage this coming event.

 

The last earthquake within about 50 km of today's event of M 2.5-2.6 in Southern

California was an M 2.7 on January 13, 2020. A series of such events have occurred in the past two weeks including an M 2.9 on January 12, 2020. Forecast 121279 had expected today's event was likely in this area around January 15.

 

NEIC reported this earthquake of M 2.6 in Southern California was felt with intensity II-III in the area(s) of Southern California at Frazier Park, Bakersfield and Moorpark.

Seismicity continued at elevated levels in Puerto Rico today. The strongest aftershock in the region was an M 4.6 today. Forecast 121228 had expected this activity around January 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.
