Debris lies strewn across a highway following a landslide near the town of Kainantu, following a 7.6-magnitude earthquake in northeastern Papua New Guinea on Sunday, Sept. 11, 2022.
A massive 7.6 earthquake struck Papua New Guinea on Sunday, causing landslides, cracking roads and damaging buildings.

While the extent of the damage remains unclear, photos showed debris strewn across highways and cracks opening up in roads.

The quake struck at a depth of 90 kilometers (roughly 56 miles) near Kainantu, a town with a population of roughly 8,500 people, the United States Geological Survey reported.

Five dead in 'massive' Papua New Guinea quake

A 7.6-magnitude earthquake shook Papua New Guinea Sunday, damaging buildings, triggering landslides and killing at least five people, with several others severely injured.

Residents in northern towns near the epicentre reported intense shaking mid-morning that cracked roads and rattled the cladding off buildings.

mmmmmm
Local member of parliament Kessy Sawang said at least two people had died in remote mountain villages, with four others airlifted to hospital in critical condition.

"There has been widespread damage," she told AFP, adding that a landslide had buried homes and "split" one village where people had "lost their houses".

In nearby Wau, Koranga Alluvial Mining said three miners had been buried alive.

There are limited communications in the area, few government resources and very few paved roads, making assessment and rescue efforts difficult.

Small aviation companies and missionary groups were involved in airlifting some of the injured across the rugged jungle landscape.

"It's very difficult, the terrain, the weather. It's challenging," said Nellie Pumai of Manolos Aviation, which had transported one person out and was trying to return.

In the eastern highland town of Goroka, residents captured images of window awnings falling off the cracked walls of a local university.

It was "very strong", said Hivi Apokore, a worker at the Jais Aben Resort near the coastal town of Madang.

"Everything was like sitting on a sea -- just floating."

The quake was felt as far as the capital Port Moresby about 300 miles (480 kilometres) away.

The US Geological Survey initially issued a tsunami warning for nearby coastal areas, but subsequently said the threat had passed.

But fearful locals near the sea nevertheless fled for higher ground -- reporting that the water level had suddenly dropped.

'Massive'

The nation's leader, James Marape, said the quake was "massive" and told people to be cautious, but said he expected the damage to be less than that from a 2018 quake and series of aftershocks, which killed an estimated 150 people.

However, the scale of the damage and number of casualties from Sunday's quake was still unclear.

"National and provincial disaster agencies, as well as leaders, have been asked to assess the damage and injuries to people and attend to these as soon as possible," Marape said.

State-backed communications firm DataCo said it was experiencing "multiple service disruptions" to the operation of a domestic undersea communications cable as well as the PIPE Pacific Cable 1 that runs from Sydney to Guam.

It was not yet clear if there was any damage to regional airports.

The quake struck at a depth of 61 kilometres (38 miles), about 67 kilometres from the town of Kainantu, according to the US Geological Survey.

Papua New Guinea sits on the Pacific "Ring of Fire", causing it to experience frequent earthquakes.

Earlier Sunday, the US Geological Survey also reported two strong quakes in the remote Mentawai Islands off the western coast of Sumatra in neighbouring Indonesia.

The New Zealand Herald reports:
Reports say death toll has risen to 10 after Papua New Guinea quake

Media in Papua New Guinea are reporting as many as 10 people have now died following the weekend earthquake.

The 7.6 magnitude quake, which was followed by a 5.0 magnitude shake an hour later, affected much of the Highlands, as well as the coastal provinces of Madang and Morobe.

It said four people have now died in Nawaeb, and three in Wau-Waria.

The secretary general of the Papua New Guinea Red Cross, Valachi Quagliata, estimated that about 100 families were hurt by falling debris, either as their houses collapsed, or from landslides.

He doubts all the people injured in the earthquake have been airlifted to safety.

The Post-Courier is reporting that the latest confirmed death is of a man killed by falling rocks by a river in Nawaeb District.

The newspaper reports eight people in the area have been injured and admitted to hospital or health centres.

"I don't think everyone has been brought out because of the geographical location of the earthquake. There's still a few finding their way to where the choppers are airlifting the people out."

There has been an extensive airlift because of the lack of medical facilities in the remote areas but he is certain there are some people still to be reached.

Quagliata said many people in the Highlands now face a tough period ahead.

"It's severe at the moment because of the fallen houses and other damage. Following the earthquake, there are assessments going on with PNG Red Cross. We're still assessing the situation right now."

Shallow 6.6 magnitude earthquake hits southwest China, death toll rises to 93 (UPDATES)

mmmmm
At least 46 people were killed when a strong earthquake struck southwestern China on Monday, state media reported, as violent tremors in a remote region damaged homes and left some areas without electricity.

The magnitude 6.6 quake hit about 43 kilometres (26 miles) southeast of the city of Kangding in Sichuan province at a depth of 10 kilometres, according to the US Geological Survey.

Tremors shook buildings in the provincial capital of Chengdu -- where millions are confined to their homes under a strict Covid lockdown -- and in the nearby megacity of Chongqing, local residents told AFP.

"I felt it quite strongly. Some of my neighbours on the ground floor said they felt it very noticeably," said Chen, a resident of Chengdu.

This week in volcano news - Earthquake swarm in Iceland, new eruption in Russia

mmmmmmmmm

At the present, there are 49 volcanoes which are actively erupting. In the last week, a new volcanic eruption began within the Kuril island chain at the Alaid volcano which has a history of highly explosive eruptions. Meanwhile in Iceland, an intense series of earthquake swarms rocked the north of the country, which some people thought had a magmatic signature. And, in New Zealand, the alert level of the White Island volcano was raised in response to a change in sensor readings.

Afghanistan earthquake of magnitude 5.3 kills eight, more casualties feared

mmmmm
An earthquake in northeastern Afghanistan killed at least eight people early on Monday, and the toll could rise, the state news agency quoted a regional official as saying.

The quake of magnitude 5.3 struck near the eastern city of Jalalabad in the early hours, the United States Geological Survey (USGS) said.

"Sunday night's earthquake has caused financial and human losses in Kunar province," Mawlavi Najibullah Hanif, the spokesman for the provincial governor, told the Bakhtar News Agency, adding that casualties could rise.

Initial reports put the toll from the quake at six, with nine injured, said disaster ministry spokesman Mohammad Nassim Haqqani.

Afghanistan is still recovering from a strong earthquake in June that killed more than 1,000 and wiped out villages in its east.

Powerful 6.9 earthquake hits equator in the Atlantic

mmmmmmmmm
A powerful earthquake with a preliminary magnitude of 6.9 has struck along the equator in the Atlantic Ocean, seismologists say, but it hit far from land and no tsunami warnings have been issued.

The earthquake, which struck at 09:42 GMT on Sunday, hit about 1,120 kilometers (695 miles) northwest of Ascension Island, which is part of the United Kingdom, or 1,350 kilometers (840 miles) southwest of Sierra Leone.

Seismologists from the U.S. Geological Survey (USGS) put the magnitude of the earthquake at 6.9. They said it struck about 10 kilometers (6.2 miles) below the seabed, making it a very shallow earthquake.

Tsunami warning centers said there was no threat of a tsunami from Sunday's earthquake, which hit along the equator, an imaginary line that divides Earth into the Northern and Southern hemispheres.

"Based on the earthquake location near the Mid-Atlantic Ridge, a damaging tsunami is not expected," the U.S. National Tsunami Warning Center said in a statement.
