A strong earthquake hit Japan on Monday.

According to US Geological Survey, the magnitude 6.3 earthquake hit the Izu-Ogasawara Islands, south of the capital Tokyo, at around 0449GMT.

The earthquake was estimated to be at the depth of 409.1 kilometers (254.2 miles).

The islands are located some 1,000 kilometers (621.3 miles) south of the capital.

MMMMMMMMMM
An undersea earthquake shook part of western Indonesia on Monday morning, but there were no immediate reports of serious damage or casualties.

The magnitude 6.2 earthquake was centered 40 kilometers (25 miles) southeast of Singkil, a coastal district in Aceh province at a depth of 37 kilometers (23 miles), the U.S. Geological Survey said.

No tsunami alert was issued by Indonesia's Meteorology, Climatology and Geophysics Agency.

Indonesia, a vast archipelago of more than 270 million people, is frequently hit by earthquakes and volcanic eruptions because of its location on the "Ring of Fire," an arc of volcanoes and fault lines in the Pacific Basin.

Earthquakes increase from 60 to 600 per week in just 5 years in Pahala, Hawaii

Shaded white areas show dense regions of earthquakes interpreted as the Pāhala sill complex. Dashed white box outlines a region of sparsely spaced volcano-tectonic earthquakes that lie between the Kīlauea summit and Pāhala.
Pāhala, a town located in the southeast part of the Island of Hawai'i, lies above the state's most seismically active area. In the last 5 years, the average weekly number of earthquakes has increased from about 60 to 600 earthquakes per week.

These frequent earthquakes occur deep beneath the Pāhala region at approximately 20 to 40 km (12 to 25 miles) depth. Larger events are regularly felt by residents living both within Pāhala and across the island.

In a 2015 study, scientists at USGS located and classified earthquakes in this region into two main groups.

A more continuous seismic tremor, a type of signal often used to trace the movement of magma within a volcanic system, was identified at approximately 40 km (25 miles) depth, both on- and off-shore of the Pāhala region. This activity was interpreted as the migration of magma from the deep Hawaiian hot spot to more shallow depths.

mmmmmmmm
Indonesia was rattled by a 7.6-magnitude deep-sea earthquake that damaged village buildings in the lightly populated island chain of Tanimbar earlier today, prompting panicked residents to flee their homes.

Two school buildings and at least 15 homes were damaged in the Tanimbar islands, said Indonesia disaster agency officials, with one person injured.

"Local residents felt strong tremors for three to five seconds. There was panic when the quake shook so the residents left their houses," Abdul Muhari, a spokesperson of the National Disaster Mitigation Agency, said in a statement, citing the local agency.

The quake struck at a depth of 130km at 2.47am local time in the Banda Sea, near the Tanimbar islands in Maluku province having a total population of 127,000 people, according to 2021 data. While a tsunami warning was put in place by local authorities, it was lifted after about three hours at 5.43am.

MMMMM
A 7.0-magnitude earthquake shook the Pacific archipelago of Vanuatu on Sunday, trigguring a tsunami warning in nearby waters.

The quake was centered 15 miles from Port Olry and hit at a depth of 17 miles at 11:32 p.m. local time, the U.S. Geological Survey said. Vanuato is about 606 nautical miles east of the Solomon Islands and 933 nautical miles from Australia.

Vanuatu has a population of 280,000 and sits on the Pacific Ring of Fire, the arc of seismic faults around the Pacific Ocean where earthquakes and volcanoes frequently occur.

The Pacific Tsunami Warning Center issued a tsunami warning for coasts within186 miles of the epicenter but it wast later withdrwan.

No initial reports of damage or casualties were reported.

In November, the Solomon Islanda was hit with a 7.0 earthquake.

Northern California officials are back in clean-up mode after the second earthquake in two weeks struck the region Sunday morning, cracking walls and roads.

The 5.4 magnitude earthquake was shallow, striking at a depth of about 19 miles, the US Geological Survey (USGS) said. It was centered about 30 miles south of Eureka and 9 miles southeast of Rio Dell, the USGS said.

A 6.4 earthquake also shook the area, about 125 miles south of the Oregon border, on December 20, resulting in two deaths.

Rio Dell Mayor Debra Garnes said the December quake also left 27 of the town's homes red-tagged - meaning they were unsafe due to damage - and 73 homes yellow-tagged. Some of the buildings were further damaged Sunday and may need to be torn down, she said.

A magnitude 6 earthquake has struck south of Vanuatu, but no tsunami warnings have been issued.

It was downgraded from an initial measurement of magnitude 6.5.

The US Geological Survey gave the quake a green alert rating, meaning there is a low likelihood of casualties and damage.

It said the quake struck at 3.34am (local time), 288km southeast of Isangel, on the island of Tanna. It was 10km deep.

An advisory from the Pacific Tsunami Warning Centre in Honolulu said no action is required "based on earthquake information and historic tsunami records".

nnnnnnnn
A strong 6.4-magnitude earthquake struck off the coast of northern California, the US Geological Survey has said, as local authorities and media reported thousands of power outages and bridge damage.

No injuries were immediately reported following Tuesday's earthquake, which occurred at 2:34 am near Ferndale, a small community about 345km (210 miles) northwest of San Francisco and close to the Pacific coast.

It was about 16.1 kilometres (10 miles) deep, USGS said.

There was no risk of a tsunami after the quake, the US tsunami warning system said.

5.4 magnitude earthquake shakes West Texas

5.4 earthquake midland texas december 2022
The earthquake was recorded about 5:35 p.m., December 16, 2022 with an origin about 12 miles east of Midland and about 3 miles below ground, according to the USGS.
The U.S. Geological Survey recorded a magnitude 5.4 earthquake early Friday evening in the Permian Basin between Midland and Big Spring, with residents reporting feeling it as far away as Lubbock, Abilene San Angelo and beyond.

The earthquake was recorded about 5:35 p.m., with an origin about 12 miles east of Midland and about 3 miles below ground, according to the USGS.

There were no immediate reports of damage, but Lubbock residents have reported feeling the earthquake, including A-J reporter Mateo Rosiles. There were also reports of the earthquake being felt by residents in Abilene and San Angelo, according to residents who reached out to the Avalanche-Journal.

Comment: The Associated Press adds:
Geophysicist Jana Pursley at the USGS's National Earthquake Information Center in Colorado said that according to early reports received by the agency, the quake was felt by more than 1,500 people over a large distance from Amarillo and Abilene in Texas to as far west as Carlsbad, New Mexico.

"It's a sizable earthquake for that region," Pursley said, adding, "In that region such an event will be felt for a couple of hundred miles."

The quake was followed shortly after by a less-intense aftershock, and Pursley said there could be more going forward with declining magnitude.

"I haven't received any information about damages but it can crack stucco or driveways close to epicenter," she added.

A quake of similar magnitude struck West Texas last month. That Nov. 16 temblor was measured at 5.3 and had an epicenter about 95 miles (153 kilometers) west of Midland.
