At least 46 people have died and hundreds left injured after a 5.6-magnitude earthquake shook Indonesia's main island of Java on Monday.

The head of the country's disaster agency BNPB said up to 700 have been injured from the earthquake.

Earlier, a government official, Herman Suherman, said at least 300 were injured from the earthquake and said this figure was from just one hospital.

He pointed out that there were four hospitals in the area, in comments that indicate the casualties and those injured from the earthquake could rise.

The national disaster agency had earlier reported 14 deaths.

The Guardian reports:
Indonesia earthquake: rescuers search for survivors as death toll rises to 252

Indonesian rescue workers were racing to reach people still trapped in rubble one day after an earthquake struck the main island of Java, as the death toll rose to 252.

Monday afternoon's quake, centred in the Cianjur region of West Java province, struck at a depth of 6.2 miles (10km), triggering landslides and damaging buildings, including thousands of homes.

The number of people killed is unclear. In an Instagram post on Tuesday the local government said 252 were confirmed dead, with 31 missing, 377 injured and 7,060 displaced.

Ridwan Kamil, the governor of West Java, said the majority of the dead were children, many of them students taking extra lessons. "So many incidents occurred at several Islamic schools," he said. Authorities were operating "under the assumption that the number of injured and [dead] will rise with time".

Provisional data released by the authorities and cited by Save the Children said about 51 education sites were affected, including 30 elementary schools, 12 junior high schools, one high school, five vocational schools and one special school.

At a local hospital, overwhelmed by the number of patients, the injured lay on the floor on mattresses and blankets, or under makeshift tents. On Monday night, victims were treated in the dark, under torchlight, due to widespread power cuts.

"Everything collapsed beneath me and I was crushed beneath this child," Cucu, a 48-year-old resident, told Reuters from the crowded hospital parking area. "Two of my kids survived, I dug them up ... Two others I brought here, and one is still missing," she said through tears.

BNPB said at least 25 people were still buried under the rubble in Cianjur as darkness fell on Monday. Efforts to reach victims been complicated by power failures, damaged roads and more than 80 aftershocks.

On Tuesday morning, hundreds of police officers had been deployed to assist in rescue efforts, Dedi Prasetyo, the national police spokesperson, told the Antara state news agency. "Today's main task order for personnel is to focus on evacuating victims," he said.

Officials were working on Tuesday to reach the area of Cugenang, which had been blocked off by a landslide.

The earthquake damaged at least 2,200 homes and displaced more than 5,000 people, the national disaster agency (BNPB) said. It said it had confirmed the deaths of 62 people, but had not verified 100 additional victims.

Mus Mustopa, who lives in Padaluyu, a village in Cianjur, told Indonesia's Kompas TV he helped a family recover the body of an 80-year-old woman who had died in the quake. It happened suddenly, he said. "I wasn't prepared and saw houses reduced to rubble ... Some 50 houses are damaged, with around 10 being heavily damaged."

Several landslides were reported across Cianjur.

Ima Mafazah, a volunteer with the Indonesian Red Cross, said tremors continued late into the evening on Monday. "Until now, the earthquake still happens, but not as big as before. A minute ago it happened again. Many people don't want to stay at their homes," she said, adding that people were traumatised, afraid and sleeping outside.

Homes had been damaged across a wide area and access was difficult due to cracked roads, said Mafazah. Nurses had been sent by the Indonesian Red Cross on motorbikes to reach the injured in four of the worst-affected areas, about one hour from the main town, that were otherwise inaccessible.

The US Geological Surveys's Pager system estimated that up to 242,000 people were exposed to "very strong shaking" and up to 978,000 people to "strong shaking". The quake was felt 60 miles (100km) away in the Indonesian capital, Jakarta, where high-rise buildings swayed.

Mayadita Waluyo, a 22-year-old lawyer, told Agence France-Presse that panicked workers ran for the exits of their building in Jakarta as the quake struck. "I was working when the floor under me was shaking. I could feel the tremor clearly," she said.

Indonesia is especially vulnerable to earthquakes because of its position on the Pacific "Ring of Fire", the most seismically and volcanically active zone in the world.

In February, a magnitude-6.2 earthquake killed at least 25 people and injured more than 460 others in West Sumatra province. In January 2021, a quake of similar magnitude killed more than 100 people and injured nearly 6,500 in West Sulawesi province.

A powerful Indian Ocean quake and tsunami in 2004 killed nearly 230,000 people in a dozen countries, most of them in Indonesia.

AP reports:
Indonesia earthquake toll reaches 310 as more bodies found

The death toll from an earthquake that struck Indonesia's Java island early this week rose to 310 after rescuers found more bodies under landslides, an official said. At least 24 people remain missing.

In devastated towns in western Java, residents gathered near badly damaged mosques for Friday prayers. Others held prayers along with rescuers between the tents at evacuation centers.

Bodies were recovered Friday in two areas of mountainous Cianjur district where landslides triggered by Monday's quake brought tons of mud, rocks and broken trees, said Henri Alfiandi, chief of the National Search and Rescue Agency.

More than 1,400 rescuers have been searching through the rubble since the magnitude 5.6 quake, which injured more than 2,000 people.

The head of the National Disaster Management Agency, Suharyanto, who uses one name, said rescuers will continue searching until rebuilding begins.

"We will do it up to the last person. There is no reduction whatsoever, in strength, enthusiasm, or the equipment," Suharyanto said.

He said distribution of food and other aid is improving and is reaching more people in 110 evacuation locations.

The disaster agency said the earthquake damaged at least 56,000 houses and displaced at least 36,000 people. Hundreds of public facilities were destroyed, including 363 schools.

An earthquake of that strength would not typically cause such serious damage. But Monday's quake was shallow and shook a densely populated area that lacks earthquake-resistant infrastructure.

Indonesia is frequently struck by earthquakes, volcanic eruptions and tsunamis because of its location on the arc of volcanoes and fault lines in the Pacific Basin known as the "Ring of Fire."

50 injured after shallow 6.1 magnitude earthquake hits Turkey

mmmmmmmmm
A magnitude-6.1 earthquake struck northwest Turkey during Wednesday's early hours, injuring at least 50 people.

The shallow tremor struck about 170 kilometres (105 miles) east of Istanbul, the country's largest city, where it was strongly felt.

National authorities said the quake was at a magnitude of 5.9 -- lower than the 6.1 given by the US Geological Survey -- and its epicentre was in Duzce province's Golyaka district, though it also shook other nearby cities.

"We were woken up with a big noise and tremor," Duzce resident Fatma Colak told AFP.

Southern California feels effect of shallow 6.2-magnitude earthquake that struck off Mexican coast

mmmmmmmmm
A magnitude 6.2 earthquake struck near the coast of Mexico's Baja California on Tuesday morning, with impacts felt over 150 miles away in Southern California.

The United States Geological Survey says the quake occurred in the Pacific Ocean, about 125 miles south of the U.S. border.

A tsunami is not expected, according to the U.S. National Tsunami Warning Center.

USGS reports indicate the earthquake could be felt as far as 200 miles away near Palm Desert, California. A USA TODAY journalist observed a small amount of shaking at an apartment building near Del Mar, California.

The USGS considers a 6.0 earthquake to be moderate and likely to cause property damage. In contrast, a 7.0 earthquake is considered strong, likely to be deadly and expected to cause billions in damage.

Comment: In addition the United States Geological Survey has the depth of the quake as 10 kms.

Buildings damaged and power lost after shallow magnitude 7 and 6 earthquakes hit Solomon Islands

nnnnnnnnn
Buildings were left damaged and widespread power outages reported in the Solomons Island capital, Honiara, after two earthquakes struck just off the south-west coast on Tuesday.

The first magnitude 7.0 earthquake briefly triggered a tsunami warning from the United States Geological Survey, but this warning was withdrawn soon after.

A second quake, with a magnitude of 6.0, struck nearby 30 minutes later.

Power was out in some areas of Honiara and Solomon Islands Broadcasting said in a statement that all radio services were off air.

The Australian prime minister, Anthony Albanese, said the roof of the Australian high commission annexe in Honiara had collapsed, "which points to likely damage throughout the city".

6.9-magnitude earthquake strikes off western Indonesia

mmmmmmmm
A 6.9-magnitude earthquake struck off western Indonesia Friday, the United States Geological Survey said, with no immediate reports of damage.

The quake hit just after 8:30 pm (1330 GMT) at a shallow depth, with an epicentre near Enggano, a small outlying island about 155 kilometres (95 miles) southwest of Sumatra's Bengkulu, the USGS said.

A magnitude 5.4 aftershock struck the same area at 9:07 pm (1407 GMT), USGS said.

"We have checked with authorities on Enggano island, the closest to epicentre and they reported the earthquake was felt weakly there, so far there has been no reports on damages or casualties, but we are still doing more assessment," spokesman of the national disaster mitigation agency Abdul Muhari told AFP.

nnnnnnnnn
Very strong magnitude 6.2 earthquake at 18 km depth

A shallow magnitude 6.2 earthquake was reported late at night near Curanilahue, Arauco, Region del Biobio, Chile.

According to the German Research Centre for Geosciences (GFZ), the quake hit on Saturday, November 12th, 2022, at 11:24 pm local time at a shallow depth of 10 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
