Earthquakes
The epicenter was located 18.4 km (11.5 miles) W of San Vito (population 3 981), 47.2 km (29.3 miles) SSE of Buenos Aires (population 11 680), Costa Rica and 54.8 km (34.1 miles) W of Volcan (population 10 286), Panama.
There are about 880 000 people living within 100 km (62 miles) and 4 700 within 10 km.
Some 25 000 people are estimated to have felt strong shaking, 165 000 moderate, 2 052 000 light and 12 661 000 weak.
The USGS issued a green alert for shaking-related fatalities and economic losses. There is a low likelihood of casualties and damage.

Earthquake strikes north east of Raba, Indonesia on Friday (Aug 17).
Earthquake strikes north east of Raba, Indonesia on Friday (Aug 17).
The magnitude-6.6 quake was located 153km north-east of Raba at a depth of 564.7km, the USGS said.
Indonesia's Meteorology, Climatology and Geophysics Agency (BMKG) said in a tweet there was no tsunami risk.
Netizens took to social media to share news about the earthquake, with some saying they had felt it in Bali, about 580 km from Raba.
The epicentre of Friday's quake was around 500km from the island of Lombok, where two deadly tremors - and dozens of aftershocks - wreaked widespread damage earlier in the month.
A magnitude-6.2 earthquake rocked Lombok on Aug 9, sparking panic after a powerful earthquake just four days earlier.
Indonesia sees frequent earthquakes as it is situated on the Pacific Ring of Fire.
Strong fluctuations recorded in the U.S. geological survey (USGS).
According to the report on their website, the epicenter of the earthquake was located at a depth of 11 kilometres, approximately 420 kilometres South-East of the village of Ogasawara.
According to preliminary data, victims and destructions, these tremors did not cause. Tsunami threat to local services is also not announced.
In notifications about emergencies that send Google, specified, in addition to Japan, the tremors could also be felt in the territory of the Northern Mariana Islands in the Pacific ocean.

Comment: This latest quake comes less than 24 hours after a magnitude 6.4 event struck the same area - the strongest ever to hit the region:
Alaska's North Slope was hit Sunday by the most powerful earthquake ever recorded in the region, the state's seismologist says. At 6:58am Sunday, the magnitude 6.4 earthquake struck an area 42 miles east of Kavik River Camp and 343 miles northeast of Fairbanks, the state's second-biggest city, the AP reports. The US Geological Survey says the earthquake had a depth of about 6 miles. State seismologist Mike West tells the Anchorage Daily News that the earthquake was the biggest recorded in the North Slope by a substantial amount. "This is a very significant event that will take us some time to understand," he says.
The previous most powerful quake in the North Slope was in 1995 at magnitude 5.2, West says. The jump from a 5.2 to Sunday's 6.4 is significant because earthquakes rapidly grow in strength as magnitude rises, he says. A magnitude 6.4 earthquake is 15.8 times bigger and 63.1 times stronger than a 5.2 earthquake, according to the US Geological Survey. "That's why at 6.4 this changes how we think about the region," West says "It's a little early to say how, but it's safe to say this earthquake will cause a re-evaluation of the seismic potential of that area." Later Sunday, another magnitude 6.1 earthquake hit at 1:15pm near the city of Kaktovik on Alaska's North Slope, the US Geological Survey says.

Motorists ride past buildings ruined by Sunday's earthquake in Pamenang, Lombok Island, Indonesia, Friday, Aug. 10, 2018. The north of the popular resort island has been devastated by Sunday's earthquake, damaging thousands of buildings and killing a large number of people.
Motorists ride past buildings ruined by Sunday's earthquake in Pamenang, Lombok Island, Indonesia, Friday, Aug. 10, 2018. The north of the popular resort island has been devastated by Sunday's earthquake, damaging thousands of buildings and killing a large number of people.
The National Disaster Mitigation Agency said on Saturday that 387 people died, jumping from the 321 it reported the previous day, as search and rescue teams continued to sift through the rubble and people already buried by relatives are accounted for.
Using satellite images of Lombok from the days following the Aug. 5 quake, scientists from NASA and the California Institute of Technology's joint rapid imaging project made a ground deformation map and measured changes in the island's surface.
In the northwest of the island near the epicenter, the rupturing faultline lifted the earth by a quarter of a meter. In other places it dropped by 5-15 centimeters (2-6 inches).
Comment: Below are some of the most notable quakes in just the last two weeks or so; Alaska has seen its strongest quake ever recorded, there have been many quakes reaching magnitude 6, and in diverse locations, and there have been earthquake swarms - our planet really is rocking and rolling:
- Deep M6.6 earthquake hits north-east of Raba, Indonesia
- Very shallow M6.4 earthquake hits Ogasawara region, Japan - preceded by another mag 6 just a minute earlier
- Magnitude 6.6 earthquake strikes near Tanaga Volcano, Alaska
- Shallow M4.4 earthquake felt across Southern California
