GREECE, BOSNIA AREA REMAINS ACTIVE

 

EARTHQUAKE SUMMARY FOR JULY 21, 2019

 

Two moderate earthquakes of M 4.2 each occurred today in the region of Montenegro and Bosnia and Herzegovina. This is probably a part of the activation of the region which has included an M 5.3 two days ago in Greece. At the time this summary noted in this regard:

 

"The full moon will arrive at 21:38 UT on July 16. Longitudes which are sub-solar at this time include areas of eastern Alaska, Canada and the NW U.S. Longitudes which are sub-lunar (antisolar) at this hour include areas of Greece and Turkey near 35-40 East longitude. These areas are likely to see enhanced seismicity at this time from tidal triggering." (July 15-17, 2019)

 

and

 

"(earthquakes at or near) 103 degrees from Southern California include southern New Zealand, Greece and Turkey and Iran/Iraq, Central Asia and China, the Northern Philippines, New Britain and eastern Indonesia. These areas could see enhanced seismicity in the coming days and are marked on the accompanying map by stippled white lines." (July 6-15, 2019)

 

The M 4.2 in Montenegro was the strongest within about 100 km of that epicenter since an M 4.4 on February 11, 2018 while the last such event in this range of the M 4.2 in Bosnia and Herzegovina was an M 4.2 on January 28, 2014. Forecast 117425 had expected today's activity was likely around July 17.

 

NEIC reported the earthquake of M 4.2 in Montenegro was felt with intensity II-III in the area(s) of Cajnice, Bosnia and Herzegovina.

A moderate earthquake near Christchurch. Canterbury, South Island, New Zealand of M 3.4-4.3 continued seismicity which began in the area yesterday. GEONET reported this earthquake was felt with moderate intensity in the area of northern South Island, New Zealand. 5168 people reported feeling this earthquake including 1046 with weak intensity; 2873 with light intensity; 1153 with moderate shaking 87 with strong; 4 with severe and  5 with extreme intensity. There were no immediate reports of damage or casualties. NEIC reported this earthquake of M 3.4-4.3 in Christchurch, New Zealand was felt with intensity II-III in the area(s) of Christchurch, New Zealand. In the previous issue of this summary this had been discussed as:

 

"GEONET reported the M 3.3-3.8 earthquake near Christchurch was felt with moderate intensity in the area of northern South Island, New Zealand. 4777 people reported feeling this earthquake including 1621 with weak intensity; 2674 with light intensity; 446 with moderate shaking 23 with strong; 2 with severe and  11 with extreme intensity. There were no immediate reports of damage or casualties. NEIC reported this earthquake of M 3.3 in South Island, New Zealand was felt with intensity II-III in the area(s) of Christchurch, Lyttelton and Taitapu, Canterbury, New Zealand. This is the first earthquake to be widely felt in Christchurch since an M 4.2 on March 10, 2017. Forecast 117489 had expected activity in this area around July 20. It is located at 102 degrees from the M 7.1 in Central California of July 6 and the M 8.0 in Peru of May 26 and was probably promoted by seismic energy from those events." (July 20-21, 2019)

Three moderate earthquakes hit the region of Guam today. This continues activity in the area as noted in previous issues of this summary:

 

"The strongest earthquake in the world today was an M 5.6 in Guam. NEIC reported it was felt with intensity II in Guam. This is the strongest earthquake in the region of Guam in nearly a year - since an M 5.8 on September 23, 2018. With the approaching typhoon season, seismicity in this area is expected to increase in coming days. Forecast 117128 had expected today's event was likely in early July within about 50 km of this epicenter." (July 17, 2019)

 

NEIC reported today's earthquake of M 4.9 in Guam was felt with intensity II-III in the area(s) of Tamuning, Guam.

The M 5.5 and 5.2 were felt with intensity III in Guam at Mangilao and Tamuning.

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.
