Earthquakes
The epicenter, with a depth of 10.0 km, was initially determined to be at 15.217 degrees south latitude and 175.021 degrees west longitude.

A 6.0 magnitude earthquake struck in the Pacific Ocean off the coast of Chile around 5.45am Tuesday, though there were no immediate reports of damage
The quake struck in the sea, 20 miles southwest of the port city of Arica at around 5.45am local time, at a depth of 20 miles, the USGS said.
Half a million people are estimated to live within a 60-mile radius of the quake and are likely to have felt it.
However, there were no immediate reports of damage and the USGS said the likelihood of casualties was low.

A car is seen on fire after a car alarm short-circuited following a strong earthquake in Tirana, Albania, November 26, 2019
The 6.4-magnitude quake struck between the port town of Durres and the capital Tirana, at a depth of 10km (6.2 miles), according to the US Geological Survey.
Witnesses said residents were rushing out of their houses in panic, but an unknown number of people could still be trapped inside buildings.
One person has died after jumping from a building, Defence Ministry spokesperson confirmed.
Officials said that the most damage was seen in Durres, while at least 50 people in Tirana had to be hospitalized.

A 6.0-magnitude tremor rattled the Greek holiday island of Crete this morning and was felt on the southern mainland, a day after tremors were felt across south-eastern Europe
The 6.0-magnitude tremor this morning left the 'whole island shaking' and houses trembling 'dramatically', witnesses said.
Experts said there were 10million people living in areas where the quake was felt, but there were no initial reports of damage.
'It was a major earthquake, the whole island shook but fortunately so far no damage has been reported,' Crete regional governor Stavros Arnaoutakis told state TV.
One witness at Efthymi in Crete said: 'It went on for a long time. I was outside and I could here the rails on the balconies creaking.'
'Strongest I have ever felt. House shook dramatically, scary ... felt that it wouldn't stop. A very long few seconds!' said another, 30 miles from the epicentre.
Since 2015, the Pacific Ring of Fire has been rattled by nearly 600 major quakes, (mag 6 or higher), see map here. Incredibly the Californian Coast has recorded just 3 major quakes in the same period and Oregon 2. The odds of this happening must be very high and surely the West Coast has to be long overdue for the big, it has to be!
To some, the "swarmageddon" 40 miles east of downtown Los Angeles has brought fear that a bigger threat was coming. To others, as long as they don't feel a shake, it is easy to just put it out of their minds. California has small quakes all the time — a magnitude 3 every other day, on average, according to the LA Times. But not all of them act the same, and some bring more danger than others. As officials install more seismic sensors as part of the state's early warning system, experts are getting an increasingly better look at California's smaller earthquakes. According to The Daily Mail, It's reminiscent of activity near the San Andreas Fault three years ago that had some scientists on edge for a possible large triggered earthquake.

A magnitude 6.3 earthquake southeast of Adak rumbled the western Aleutian Islands at 3:54 p.m. Saturday, Nov. 23, 2019.
An earthquake with a reviewed magnitude of 6.3 rumbled in the Aleutian Islands on Saturday afternoon, according to the Alaska Earthquake Center.
The earthquake at 3:54 p.m. was centered 59 miles southeast of Adak at a depth of 16.1 miles, the center reported. Several aftershocks -- the strongest registering at magnitude 3.6 -- were recorded in the region.
Shaking was felt in Adak, according to citizen reports.
A tsunami was not expected, according to the National Tsunami Warning Center.

The quake jolted at 7:11 p.m. Jakarta time (1211 GMT) with the epicenter at 280 km northeast Tambrauw of the province and a depth of 10 km under sea bed, official in charge at the agency Abdul Rosid said.
"There (is) no potential of tsunami from happening so that we did not issue a warning," he told Xinhua over phone.
Indonesia is prone to quake for its position on the quake-impacted zone so-called "the Pacific Ring of Fire."
The Hindu Kush runs for hundreds of miles and straddles the border of Afghanistan and Pakistan. It is one of the most seismically active areas in the world.
Every year, the mountain range gets rocked by more than 100 earthquakes that measure a magnitude of 4.0 or higher. It also experiences many intermediate-depth quakes that happen between 45 to 190 miles (70 to 300 kilometers) below the surface.
Until recently, experts didn't know why the Hindu Kush suffers so many earthquakes at intermediate depths. The mountain range doesn't sit on top of a significant fault line, which any California resident knows causes numerous earthquakes.
Further, the mountains are some distance away from the ongoing collision between the Eurasian and Indian tectonic plates. Therefore, the usual candidates for the cause behind constant earthquakes are absent from the area. (Related: Fracking-induced earthquakes in Central and Eastern America are on the rise, caution researchers.)
Comment: There are other important factors to consider when studying tectonic plate movements, to increase our understanding of the subsequent seismic and volcanic activity, and also the formation of sinkholes (all of which are increasing at an alarming rate!), such as:
1. The slowdown of the Earth's rotation - causing mechanical stress on the crust.
2. Crustal slippage - the difference in rotation between the crust and mantle.
3. Reduction of the surface/core electric field.
4. Electromagnetism.
These factors, the Electric Universe theory, and much more are fully explained in Earth Changes and the Human-Cosmic Connection.
Residents in Chiang Mai province felt a long period of shaking but saw no major damage. High-rise buildings swayed slowly for at least half a minute in Bangkok, startling residents.
The US Geological Survey said the 6.1 magnitude quake on Thursday morning was about 10 kilometers below the surface.
It was centered in northwestern Laos, about 31 kilometers from Chaloem Phrakiat district in Nan province.
Moderate quakes of 4.6 and 5.7 magnitude shook the same area overnight.
