===================================
USGS and EMSC do not agree. Reporting data from both.
Earthquake totals in last 24 hours (ending 10AM EDT) according to:
http://earthquake.usgs.gov/earthquakes/map/32 'quakes of magnitude >2.4 ⋅ Total mags = 112.6 ⋅ Avg mag = 3.52 ⋅ (*)
http://www.emsc-csem.org/Earthquake/?filter=yes134 'quakes of magnitude >2.4 ⋅ Total mags = 464.2 ⋅ Avg mag = 3.46 (**)
(*) Magnitude >2.4 in USA, and >4.4 elsewhere (>2.4 worldwide not available). Note: that criterion is not applied consistently everywhere; smaller 'quakes are included in some regions sometimes, and sometimes 'quakes with mag. >4.4 per EMSC are absent per USGS.
USGS has 9 'quakes of mag. >4.4, and EMSC has 10.
(**) The listing of 'quakes has 153 events, but the download gave 134 lines.

Count:
171 'quakes. (Note: EMSC has 28 'quakes of 2.5≤ magnitude <3.0. 171+28 =
199)
Max mag. 6.5 in "Central Mid Atlantic Ridge".
This site compiles data from more sources than only EMSC and USGS.
The map is interactive and can show volcanoes as well as earthquakes.
---------------------------------------
Three strongest 'quakes from USGS and EMSC (plus one):
* Mag.
6.5 in south mid-west North Atlantic Ocean, opp. north-most Brazil. (both sites).
* Mag. 5.1 in south mid-east Philippines (both sites).
* Mag. 5.0 in Vanuatu (both sites).
* Mag. 5.0 in south west Iran (both sites).
Largest groups of multiple 'quakes from either site (short list: counts > 9 approx.):
* 25 in and offshore west of southern Mexico; max mag. 4.
4 (EMSC. USGS:
1).
* 14 in Indonesia; max mag. 4.8 (EMSC. USGS: 2). (*)
* 14 in Chile incl. 2 nearby in Argentina; max mag. 4.
4 in Argentina (EMSC. USGS:
1).
* 12 in Philippines; max mag. 5.1 (EMSC. USGS: 1).
* 11 off the north coast of North Island, New Zealand; max mag. 4.2 (EMSC. USGS: 0).
(*) 1 'quake nearby in Philippines is counted in another line.
Notes:
* The max mag. for each group can be from the site with the least number of 'quakes.
* Different sites may have the same number of 'quakes in a region but not the same ones or the same max mag.
* All source sites have a variable processing delay of perhaps from 2 to 20 minutes, normally.
* The facilities available allow for recovery today of 'quakes lost in processing delay at cut-off time yesterday for EMSC but not for other sites. That accounts for some cases of EMSC having one or two more 'quakes than USGS does in a region.
* Doing multiple downloads starting as soon after 09:59:59 AM EDT as sources update can take up to 5 minutes and give inconsistent results for that time interval. Sources update at intervals ranging from perhaps 1 minute to 5 minutes. (They do not update after every 'quake.)
======================================
From USGS (USA all 'quakes, separate data capture, 24 hours ending 10AM EDT 31/Aug/20):
*
98 'quakes of all magnitudes in California and nearby in Mexico (max mag. 3.0).
* 49 'quakes of all magnitudes in Nevada (max mag. 2.6).
* 29 'quakes of all magnitudes in Alaska (max mag. 3.2).
* 15 'quakes of all magnitudes in Hawaii (max mag. 2.7).
* 10 'quakes of all magnitudes in Puerto Rico (max mag. 2.9).
* 8 'quakes of all magnitudes in North Carolina (max mag. 1.9). (*)
* 1 or 2 'quakes of any magnitude in: Washington, Utah, Oklahoma, and western Texas (max mag. 2.9 in TX).
(*) This continuing series of weak and shallow events, all in the same small region, would most likely be explosions in underground facilities.
> No 'quakes of any magnitude in Yellowstone Park (NW Wyoming plus strips of Montana and Idaho).

Note: Quarry blasts and explosions, if any, are shown on the map but not included in the 'quake counts above.
> Explosions: Alaska 1.
> Quarry blasts: California 1.
---------------------------
From EMSC (two separate data captures; 'quake counts are not necessarily consistent):
* 38 earthquakes of magnitude ≥2.0 in last 24 hours in Euro-Med region, according to
http://www.emsc-csem.org/Earthquake/Map/zoom.php?key=1&typ=world#2[IMAGE Aug31-2020_quakes_min-mag-2_Iberia_to_Iran_per_EMSC_24-Hrs_Aug31-2020.jpg] has 35 'quakes.
