=================================
USGS and EMSC do not agree. Reporting data from both.
Earthquake totals in last 24 hours according to:
http://earthquake.usgs.gov/earthquakes/map/15 'quakes of magnitude >2.4 ⋅ Total mags = 54.8 ⋅ Avg mag = 3.65 (*)
http://www.emsc-csem.org/Earthquake/?filter=yes90 'quakes of magnitude >2.4 ⋅ Total mags = 322.9 ⋅ Avg mag = 3.59
(*) magnitude >2.4 in USA, and >4.4 elsewhere. (>2.4 worldwide not available).
Note: USGS has 6 'quakes of mag. >4.4, and EMSC has 12.
------------------------
Three strongest 'quakes from either site:
* Mag. 5.6 east of the southern end of New Caledonia (USGS. EMSC: 5.5).
* Mag. 5.2 north of Fiji largest island (both sites).
* Mag. 5.1 in north central South Atlantic Ocean, opp. Gabon (both sites).
Largest groups of multiple 'quakes from either site:
* 28 in Mexico; inland and offshore of the west coast mid-south and south, mid-south mid-east, and south-end mid-north (EMSC. USGS: 1).
max mag. 4.5⋅
* 10 in Chile; north, mid-north, offshore mid-south, and nearby in Argentina, Bolivia, and Peru (EMSC. USGS: 1).
max mag. 4.9⋅
* 9 in Indonesia (Papua, mid-east, central, and west):
Papua east mid-north, and off south coast west;
mid-east north and beyond-south;
central mid-north and beyond-south; and
west mid-south and off the west coast south (EMSC. USGS: 0).
max mag. 4.7⋅
* 8 in Turkey; west incl. nearby islands, and east (EMSC. USGS: 0).
* 7 in Greece; off west coast mid-south, west mid-north, and far NE nearby in Bulgaria (EMSC. USGS: 0).
* 5 in Dominican Republic; off north coast mid-west and east, off south coast east, and west mid-south nearby in Haiti (EMSC. USGS: 1).
* 4 in Alaska; mid-east south to off south coast central (USGS. EMSC: 1).
* 4 in Costa Rica; mid-south central, and south-east nearby in Panama (EMSC. USGS: 0).
Comment: USGS's exclusion of magnitudes <4.5 outside of USA fails to reveal groups of 'quakes of increasing significance. Note that that policy is not applied consistently everywhere.
Comment: The factors that caused 'quake-groups frequently in and around Puerto Rico appear to have moved west to the Dominican Republic. Note that USGS reports 'quakes of magnitude <4.5 in Puerto Rico but not always in Dominican Republic. Note also that USGS reports more 'quakes >4.4 in Puerto Rico than EMSC does. USGS reports selectively from Dominican Republic, whether magnitudes are >4.4 or not, and not necessarily selecting the 'quakes of largest magnitude. The reporting boundary between PR and DR is arbitrary, and 'quakes between them could often be assigned to either region. Anyway, it is the
shift in group location that is noteworthy.

From USGS (all 'quakes, separate data capture, see notes):
*
114 'quakes of all magnitudes in California, Nevada, and nearby in Mexico (max mag. 2.6).
*
63 'quakes of all magnitudes in Alaska and nearby in Canada (max mag. 2.7).
* 10 'quakes of all magnitudes in Hawaii (max mag. 3.1).
* Strong 'quakes (mag. > 2.4) in Nevada (USA); and in Alaska (3 Qs), Hawaii, and Puerto Rico.
* Little shakers (mag. 1.0 ~ 2.4) in western Montana, California and nearby in Mexico, and Nevada (USA); and in Alaska and nearby in Canada (57 Qs), Hawaii (9 Qs), and Puerto Rico region
excl. Dom. Repub. (5 Qs).
* 57 little shakers in California, Nevada, and nearby in Mexico; plus many smaller ones. (All-magnitude clusters in California: SE of Los Angeles and nearby, and mid-north mid-west; and minor cluster in south mid-east Nevada.)
* No 'quakes of any magnitude in Yellowstone Park (NW Wyoming plus strips of Montana and Idaho), bur 1 nearby west (mag. 1.4).
Notes: Quarry blasts and explosions are excluded from above lists and totals, except where otherwise indicated.
USGS lists some sites near borders as near locations across the border (worldwide).
Earthquake
counts less than 3 are not reported, except where otherwise indicated.
The later data capture for this sub-section causes some inconsistencies with the earlier data set.
----------------------------
From EMSC (two separate data captures):
34 earthquakes of magnitude >1.9 in last 24 hours in Euro-Med region, according to
http://www.emsc-csem.org/Earthquake/Map/zoom.php?key=1&typ=world#2 (approx. 9 only in Greece, and 18 in Turkey).
