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.

Earthquake of magnitude 6.2 hits 253 km Northeast of Kuala Lumpur, Malaysia

mmmmmmm
A 6.0-magnitude earthquake hit off the coast of Indonesia late Tuesday, according to the US Geological Survey, sending people fleeing their homes but with no casualties or damage immediately reported.

The shallow quake occurred in the waters off the southwestern coast of Sumatra island, at around 9:30 pm (1430 GMT) -- nearest to Bengkulu, South Sumatra and Lampung provinces.

It sent people in South Sumatra and Bengkulu rushing from their homes, according to local media and witnesses contacted by AFP.

However no casualties or damages were immediately reported by authorities, and USGS estimated that there would be little chance of damage on the ground in Sumatra island. No tsunami threat was issued.

6.1 Magnitude earthquake strikes off New Caledonia coast

CCCC
A strong earthquake measuring 6.1 on the Richter scale struck off the coast of New Caledonia in the South Pacific Ocean.

The epicenter of the earthquake occurred southeast of the Loyalty Islands off the eastern coast of Caledonia, at a depth of 80.6 kilometers, US Geological Survey said.

There were no immediate reports of casualties or material losses due to the quake.

New Caledonia lies in the Pacific's Ring of Fire, where tectonic plates meet, the friction of which leads to intense seismic and volcanic activity.

This week in volcano news - Taal might erupt, continuing eruption in Iceland

MERADALIR ERUPTION

MERADALIR ERUPTION

In the last week, a potential new volcanic eruption may have begun in American Samoa. Meanwhile, in the Philippines, the dangerous Taal volcano is displaying significant signs of unrest, meaning it might erupt again with little or no warning. And, in Iceland, the Meradalir volcano is continuing its fissure eruption. This video will discuss these volcano related news stories, as told and analyzed by a volcanologist.

This week in volcano news: A new eruption in Iceland at Meradalir, unrest at Iwo Jima

Meradalir Eruption Ever Changing

Meradalir Eruption ever changing
This week, a new volcanic eruption began in Iceland at Meradalir. The fissure eruption has already began to construct a cinder cone at a higher rate than witnessed in the 2021 eruption. Meanwhile, in Japan, the Iwo Jima volcano and caldera produced a new series of explosive and shallow submarine eruptions. And, also in Japan, another island volcano was placed on a heightened alert level due to seismic unrest. This video will discuss these volcano related news stories, as told and analyzed by a volcanologist.

Iceland volcano eruption update - New eruption begins at Geldingadalir, lava flows from a fissure

The eruption in Geldingadalir started at 13:18 today.

The eruption in Geldingadalir started at 13:18 today.
Earlier today, a new volcanic eruption began in Iceland. Just northeast of where Geldingadalir famously erupted in 2021, the same volcanic system ejected lava out of a 100 meter long fissure. As a result, the alert level of this Iceland volcano was temporarily raised to red, and the eruption plume became visible across the peninsula. So, what will happen next? Where will the lava flow? This video will answer these two questions and the ongoing volcanic eruption.
