6.5-magnitude earthquake hits Papua New Guinea: USGS

A strong 6.5-magnitude earthquake hit northern Papua New Guinea early Monday, but there was no threat of a tsunami, US seismologists said.

The epicentre of the quake, which hit at 0656 local time (2056 GMT), was roughly 110 kilometres (68 miles) east-southeast of Kimbe on the island of New Britain, at a depth of 64 kilometres, the US Geological Survey said.

The Pacific Tsunami Warning Centre said in a statement that there was "no tsunami threat". There were no immediate local reports of damage.

The region was rattled last month when at least five people were killed and an estimated 1,000 homes destroyed following a magnitude 6.9 earthquake.

A magnitude 7.2 earthquake struck off the eastern coast of Taiwan on Wednesday morning, damaging buildings and triggering a tsunami warning.

The earthquake struck off the coast of Hualien Country at 7:58 am local time and was felt across the island, including its capital Taipei, officials said.

Wu Chien-fu, the head of Central Weather Administration's Seismological Center, said it was the strongest earthquake to hit Taiwan since 1999. Despite its power, no casualties have been immediately reported.

Several tall buildings have partially collapsed. In other regions, the earthquake has triggered landslides.

Comment: Updates

NBC News reports:
A 7.4-magnitude earthquake struck Wednesday off Taiwan, killing nine people, injuring hundreds and collapsing buildings in the island's most powerful tremor in at least 25 years.

The quake happened around 8 a.m. local time (8 p.m. Tuesday ET) at a depth of about 21 miles, according to the U.S. Geological Survey. It was about 11 miles south-southwest of Hualien City on the island's east coast.

At least nine people died and 882 people were injured, Taiwan's fire department said. Officials said the number of casualties could rise in the coming days.

The earthquake also prompted tsunami warnings that were later lifted in Taiwan, Japan and the Philippines.

Annie Lima, an American who has lived in Taiwan for almost 17 years and arrived in Hualien to visit friends on Tuesday, said she was still feeling aftershocks in the afternoon, hours after the initial quake.

"It was pretty scary," she told NBC News in an interview. "In all the years that I've lived here and in Southern California before that I've felt a lot of earthquakes, but this was by far the strongest and the most frightening."

When things started toppling, Lima said, she and her husband jumped to their feet and ran for the nearest doorway.

"Even there in a doorway on the second floor, we could barely keep our balance, you know, holding both sides of the doorway," she said. "And all around us things were falling off the walls and off shelves, smashing and crashing everywhere."

The damage was concentrated in the eastern Taiwan county of Hualien, near the quake's epicenter, where officials said they were working to free 131 people who were trapped.

Video on social media showed a building in Hualien that appeared to be nine stories tall partially collapsed and left standing at an angle. Another, appearing to have five floors, was similarly situated.
Update April 10

AFP reports:
The toll from a massive earthquake that struck Taiwan last week rose to 16 on Wednesday after three more bodies were recovered on a hiking trail, officials said.

The magnitude 7.4 quake that hit the island on April 3 also left more than 1,100 people injured, with strict building codes and widespread disaster readiness credited with averting an even bigger catastrophe.

Authorities discovered the three victims Wednesday as they worked to retrieve two other bodies buried under the rocks along the Shakadang Trail in eastern Taiwan's Hualien county, the quake's epicenter.

The new fatalities brought the toll from the quake to 16, according to the National Fire Agency. Three people remain missing.
Earthquake Track reported an aftershock of magnitude 6.4 about 13 minutes later.


Earthquake of 6.6 magnitude hits Indonesia, no tsunami alert

A magnitude-6.6 earthquake hit Indonesia's eastern region on Tuesday, the United States Geological Survey said, with no tsunami warning issued.

The quake struck off Halmahera island in North Maluku province at 0948 GMT at a depth of about 35 kilometres (22 miles), the USGS said.

There were no immediate reports of damage or injuries after the earthquake.

The Pacific Tsunami Warning Centre said there was "no tsunami threat" from the quake in the Molucca Sea.


Shallow 6.0-magnitude earthquake shakes eastern Indonesia

An earthquake with a magnitude of 6.0 hit Indonesia's eastern province of West Papua on April 9, but did not trigger a tsunami warning, according to Indonesia's Meteorology, Climatology, and Geophysical Agency.

The earthquake occurred at around 7am, with its epicentre situated 46 km southeast of Ransiki town, and at a depth of 11 km under the seabed, the agency was quoted by local media.

The intensity of the quake was felt at III to IV MMI (Modified Mercalli Intensity) in the Ransiki town, it added.

The agency did not issue a tsunami warning as the tremors would not potentially trigger giant waves.

Indonesia is prone to earthquakes for its location along the Pacific Ring of Fire, a tectonic belt of volcanoes and earthquakes.


6.8 magnitude earthquake registered near Mariana Islands

A powerful 6.8 magnitude earthquake struck near the Mariana Islands Friday morning, the United States Geological Survey is reporting.

The notable quake was recorded just after 6 a.m. local time (4 p.m. ET Thursday), according to the USGS, in the Maug Islands region near Saipan, the northern-most largest of the Mariana Island.

The Mariana Islands are in the western Pacific Ocean north of the equator, northeast of Guam and are part of the United States.

It was not immediately known if anyone was injured.

But as of late Friday morning no tsunami warning, advisory, watch or threat had been issued in the area by the National Oceanic and Atmospheric Administration or National Weather Service.

An earthquake shook the densely populated New York City metropolitan area on Friday morning, the US Geological Survey said, with residents reporting they felt rumbling across the eastern seaboard in what is a relatively rare event for the region.

The government agency reported a quake with a preliminary magnitude of 4.8, centered near Lebanon, New Jersey.

People reported feeling the quake in the states of Connecticut and Massachusetts, with the Weather Channel reporting that it was noticeable in Boston and residents in Philadelphia reporting they felt it, too. Tremors lasting for several seconds were felt more than 200 miles away near the New Hampshire border.

The fire department of New York said on Friday there were no initial reports of damage or injury. But city dwellers were shocked and a little shaken up by the unexpected event, during which people sitting at desks or at home in high rises felt their whole building shake mildly for several seconds.

The movement then passed but people were left jittery about aftershocks and busily checking in with friends and family, including children at school, briefly putting a high load onto cellphone networks, the city authorities reported.

The New York police department's deputy commissioner of operations, Kaz Daughtry, said in a statement: "While we do not have any reports of major impacts at this time, we're still assessing the impact."

The UN security council was meeting at its headquarters in New York to discuss the situation in Gaza when the earthquake hit, shaking the building.

6.1 magnitude earthquake strikes eastern Japan

A strong earthquake of 6.1 magnitude shook Japan's Minamisoma region on Thursday, according to the US Geological Survey.

The tremor occurred 83 kilometers (51 miles) east of Minami-Soma in the province of Fukushima at a depth of 40 kilometers, the agency said, with no tsunami warning issued.

There was no report of any damage.

According to Japanese media, the quake was felt in Iwate, Miyagi, and Fukushima provinces at 12.16 p.m. local time (0316GMT), with no abnormalities confirmed at the crippled Fukushima Daiichi nuclear power plant.

This came after a powerful magnitude 7.4 earthquake struck off Taiwan's eastern coast on Wednesday, killing at least nine people, while hundreds others were injured.

The quake was the strongest to have hit the island nation in 25 years. In 1999, around 2,400 people were killed when a 7.7-magnitude earthquake struck Taiwan in the middle of the night.

The extraordinary climate events of 2022-24

The unlikely volcano, the warmest year, and the collapse of the polar vortex.

The climate events of 2022-24 have been were truly extraordinary. From an unlikely undersea volcanic eruption to the warmest year on record to the collapse of the polar vortex after three sudden stratospheric warming events. This rare convergence presents a unique learning opportunity for climatologists and climate aficionados alike, offering insights into a climate event that may not be repeated for hundreds or even thousands of years.

1. January 2022, the unlikely volcano

Never before have we witnessed an undersea volcanic eruption with a plume capable of reaching the stratosphere and depositing a large amount of vaporized water. This extraordinary event occurred in January 2022 when the Hunga Tonga volcano erupted. The conditions for such an event are rare: the volcano must be deep enough to propel enough water with the plume, but not too deep to prevent it from reaching the stratosphere. Most undersea volcanoes do not produce plumes at all, which makes Hunga Tonga's eruption all the more remarkable.

The Hunga Tonga volcano occupied a unique "sweet spot" at a depth of 150 meters the day before the eruption. In addition, the eruption itself must be exceptionally powerful for water vapor to rise into the stratosphere. The January 2022 eruption of Hunga Tonga was the most powerful in 30 years, since the 1991 eruption of Mt. Pinatubo.

Active undersea volcanoes at the appropriate depth are rare, and the likelihood of one erupting with such intensity is relatively low. We may be looking at an event that occurs once every few centuries, or maybe even once every millennium. Undoubtedly, it was an exceptionally rare event.

While the most powerful eruptions, such as Tambora in 1815, can indeed strongly influence hemispheric weather for a few years, our observations of eruptions such as Agung (1963), El Chichón (1982), and Pinatubo (1991) suggest that their effects dissipate within 3-4 years.
