USGS and EMSC do not agree. Reporting data from both.
Earthquake totals in last 24 hours according to:

http://earthquake.usgs.gov/earthquakes/map/
25 'quakes of magnitude >2.4 ⋅ Total mags = 96.8 ⋅ Avg mag = 3.87 (*)

http://www.emsc-csem.org/Earthquake/?filter=yes
104 'quakes of magnitude >2.4 ⋅ Total mags = 383.3 ⋅ Avg mag = 3.68

(*) magnitude >2.4 in USA, and >4.4 elsewhere. (>2.4 worldwide not available).
USGS has 8 'quakes of mag. >4.4, and EMSC has 11.
------------------------

Three strongest 'quakes from either site:
*  Mag. 6.3  between New Zealand (nearest) and Tonga (both sites).
*  Mag. 5.7  off the east coast central of Kamchatka Peninsula, Russia (both sites).
*  Mag. 5.3  between New Zealand (nearest) and Tonga (both sites).

Largest groups of multiple 'quakes from either site:
*  26  in Mexico; inland and offshore of the west coast mid-south and south and nearby offshore Guatemala, and south mid-west (EMSC.  USGS: 0).  max mag. 4.2
*  23  on and off the coast in west south Panama and nearby Costa Rica (EMSC.  USGS: 0).  max mag. 5.0
*  14  in Indonesia (Papua, mid-east, central, and west):  Papua mid-east north to central;  mid-east mid-south;  central central and south and beyond-south;  and west off the west coast north (EMSC.  USGS: 4).  max mag. 5.1
*  9  in Puerto Rico and Dominican Republic combined regions; east (PR) and Virgin Islands, middle, and west (DR) (EMSC: 6.  USGS: 6.  Duplicates: 3.).  max mag. 3.3
*  8  in Chile; north, mid-north, mid-south, and nearby in Argentina and Peru (EMSC.  USGS: 0).  max mag. 3.7
*  5  in Turkey; west incl. nearby islands, central, and east and nearby in Syria (EMSC.  USGS: 0).

*  3  in and/or around each of: ⋅ offshore Kamchatka Peninsula, Russia,  Greece,  and Peru (3 in addition to 1 near Chile) ⋅ (at least one source site each).

Note:  Neither USGS nor EMSC report fully on both Puerto Rico (PR) and Dominican Republic (DR).  Basically, USGS covers PR, and EMSC covers DR, with some possible overlap in locations and magnitudes.  USGS applies different minimum magnitudes to PR and DR, but not consistently.  I have combined PR and DR together as one region and simply recorded totals that USGS and EMSC report for that whole region, and specifying "occupied" internal locations only as west (DR), middle, and east (PR) sections.  Nearby locations included when they occur are Haiti (with DR) and Virgin Islands (with PR).

Comment: USGS's exclusion of magnitudes <4.5 outside of USA fails to reveal groups of 'quakes of increasing significance.  Note that that criterion is not applied consistently everywhere.
--------------

From USGS (all 'quakes, separate data capture, see notes):

123  'quakes of all magnitudes in California, Nevada, and nearby in Mexico (max mag. 3.2).
84  'quakes of all magnitudes in Alaska and nearby in Canada (max mag. 2.7).
*  12  'quakes of all magnitudes in Puerto Rio extended region (max mag. 3.3).

*  Strong 'quakes (mag. > 2.4) in western Montana, and California and nearby in Mexico (3 Qs) (USA);  and in Alaska, Hawaii, and Puerto Rico extended region (6 Qs).

*  Little shakers (mag. 1.0 ~ 2.4) in Washington, Idaho, western Montana, NW Wyoming, California and nearby in Mexico, Nevada, Oklahoma (4 Qs), NE Arkansas, and NW Tennessee (USA);  and in Alaska and nearby in Canada (75 Qs), Hawaii (7 Qs), and Puerto Rico (6 Qs).

*  48 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.)

*  3 'quakes of all magnitude in Yellowstone Park (NW Wyoming plus strips of Montana and Idaho) (max mag. 1.4).
+  2 'quakes of all magnitudes near to New Madrid, SE Missouri (max mag. 1.8).

Notes:  Puerto Rico extended region includes Virgin Islands and nearby in Dom. Repub. region.
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):
21 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. 4 only in Greece, and 11 in Turkey).

USGS and EMSC do not agree. Reporting data from both.
Earthquake totals in last 24 hours according to:

Ditrianum commented yesterday that it's not planetary geometry that set off the recent large quake in Southern California, but lunar geometry, which happens due to the elliptical orbit of the moon, which sometimes approaches earth more closely than at other times.

Update: Another strong quake was predicted yesterday by experts and it did hit,  a strong 5.4 in southern CA.
The big 6.4 quake could be felt in Los Angeles.
Over 200 aftershocks,  one article below:

California earthquake generates more than 200 aftershocks
By Jay Croft and Braden Goyette, CNN

Updated 3:43 AM ET, Fri July 5, 2019

Los Angeles (CNN)The strongest earthquake to hit Southern California in nearly 20 years prompted one city to declare a state of emergency Thursday, and shook residents from Las Vegas to Orange County.

The quake, with a magnitude of 6.4, was centered near Ridgecrest, a community west of the Mojave Desert and about 150 miles north of Los Angeles.
At least 200 aftershocks of magnitude 2.5 or greater have been recorded after the earthquake through midday Friday, according to the US Geological Survey. It is a higher than normal number, but not unprecedented, he said. The largest of them were magnitude 4.6.

Noted seismologist Lucy Jones called it a "robust" series and said there is a 50% chance of another large quake in the next week.
Jones said there is a 1 in 20 chance that a bigger earthquake will hit within the next few days. "It's certain that this area is going to be shaking a lot today and some of those aftershocks will probably exceed magnitude 5."
Jones said the quake, named the Searles Valley Quake, was preceded by a magnitude 4.2 foreshock.

Hospital evacuated
Ridgecrest has announced a state of emergency, Mayor Peggy Breeden said. As the mayor spoke to CNN earlier in the day, an aftershock interrupted the interview.
"As I understand, we have five fires," the mayor said. "We have broken gas lines."
Footage from Ridgecrest showed firefighters hosing down flames rising from homes.

There were also power outages in the city of 28,000 residents. The forecasted high temperature is 100 degrees Fahrenheit, the National Weather Service said.
In Kern County, at the epicenter, the Fire Department responded to more than 20 incidents relating to the earthquake and aftershocks, including fires and medical emergencies, according to a tweet on its verified account.
Ridgecrest Regional Hospital was evacuated. About 15 patients from the emergency room were taken to another hospital, and inspectors were going through the facility to determine whether it was safe to bring the other patients in from the tented areas outside.
April Rodriguez was at home in Trona when she felt a smaller quake followed by a larger one "that didn't stop," she told CNN.

"We were panicked trying to get out of the house because everything is falling out of the cabinets, off the shelves, off the walls. ... They were flying like missiles off the shelves."

Kimberly Washburn was directing a children's July Fourth program in Ridgecrest when the earthquake shook the building, starling the 65 children on stage.
With their parents in the auditorium seats, the kids began screaming.
"It was terrifying," she said.
One boy was injured when something fell on his foot, but Washburn said they were blessed that more weren't hurt. After they evacuated, a wall fell behind where the children had been performing, she said.
In LA the ground rolled
In Los Angeles, the main temblor was felt as a long, rolling quake, and buildings rocked back and forth. Many in the city noted how much longer this earthquake felt than most.
Filmmaker Ava DuVernay tweeted, "Been living in Los Angeles all my life. That was the longest earthquake I've ever experienced. Not jerky. Smooth and rolling. But it was loooong. It was so long I thought for the first time ever, 'Is this the big one?' Damn. Respect Mother Nature. She's the boss."

 Been living in Los Angeles all my life. That was the longest earthquake I’ve ever experienced. Not jerky. Smooth and rolling. But it was loooong. It was so long I thought for the first time ever “Is this the big one?” Damn. Respect Mother Nature. She’s the boss.
...

Many residents were upset because the city's one-of-a-kind smartphone app didn't send a warning in advance. Afterward, city authorities said they would change the parameters on the application to issue alerts for smaller quakes.
The rolling ground also caused Disneyland officials to temporarily shut down rides.
The National Weather Service tweeted that the earthquake was also felt in Las Vegas.
"I was actually sitting at the blackjack table at the Wynn and it just felt like I was on a boat," Alec Ventresca told CNN affiliate KLAS. "I actually thought the guy that I was sitting with was kicking the table."
It was the largest quake to hit Southern California since 1999, when a 7.1 earthquake struck in a remote part of the Mojave desert.
In 1994, at least 57 people died when a 6.7 earthquake hit the Northridge neighborhood of Los Angeles, causing $25 billion in damage.

Fires break out after another powerful earthquake hits near Ridgecrest in Southern California
By Christina Maxouris, CNN

Updated 12:24 AM ET, Sat July 6, 2019

(CNN)A 7.1-magnitude earthquake hit Southern California on Friday night -- the second one near Ridgecrest in less than two days.

The latest earthquake occurred 11 miles northeast of Ridgecrest, according to the US Geological Survey.
It comes a day after a 6.4-magnitude earthquake centered near Ridgecrest rattled the state Thursday. That earthquake has produced more than 1,400 aftershocks, scientists said.
Multiple fires and injuries have been reported in Ridgecrest -- about 150 miles from Los Angeles -- after Friday's earthquake, Kern County spokeswoman Megan Person told CNN. An emergency operations center is being set up in Bakersfield, she said.
In central Los Angeles, Friday's earthquake felt stronger than the one a day earlier, making buildings rock back and forth forcefully. Donald Castle, who lives in Porterville west of Ridgecrest, said his house shook for between 20 and 25 seconds.
"It was more of a shake than what we had on the Fourth. It lasted longer and was more rolling," he said.
The shaking was felt all the way in Las Vegas, much like the earthquake a day earlier.
The NBA Summer League game between the New Orleans Pelicans and the New York Knicks in Las Vegas was delayed Friday following reports of the quake. Scoreboards and speakers near the ceiling of the arena shook when the earthquake hit.
Public safety units are being deployed throughout the city " to ensure safety and inspect infrastructure," Los Angeles Mayor Eric Garcetti said.
Noted seismologist Lucy Jones said Friday both earthquakes are part of an ongoing sequence, of a "very energetic system."
Officials are not ruling out that there could be more earthquakes coming.
This is a developing story, please check in for updates.
CNN's Phil Gast, Braden Goyette, Sheena Jones, Sarah Moon, Steve Almasy and Nicole Chavez contributed to this report.
