An earthquake struck Anglesey last night measuring 1.3 on the Richter scale, with its epicentre recorded as Llanfigael, according to the British Geological Survey

Anglesey was hit by an earthquake last night, with terrified witnesses reporting a sound "like thunder".

The quake measured 1.3 on the Richter scale and its epicentre was in Llanfigael, according to the British Geological Survey. The exact time of the quake was 11.27pm, at a depth of 12km. Despite not being a large earthquake, a post on the North Wales Storm Watch Facebook group described the sound as "like thunder with a bang nothing like past quakes that we have had here also sounded like it was in the sky".

Comment: A airburst like a mini-Tunguska event? The small size of the quake, as opposed to the sound it made would seem to point in that direction.

Ground uplift continues at Thorbjorn Complex, volcano-tectonic unrest affecting wide area of Reykjanes Peninsula, Iceland

Updated 29th of October at 2pm

The latest cGPS deformation data around the Þorbjörn and Svartengi area confirm that the deformation, which started 27 October, continues. As initially stated, the ongoing deformation rates are higher than in previous events which occurred in a similar area in 2020 and 2022. Overall, the seismicity north of Grindavík has been declining over the past 24 hours and there are no significant changes in earthquake depths. However, it is important to emphasise that the current deformation may trigger renewed seismicity in the area that could be felt by people.

New satellite data are expected to be delivered later today, and a new interferogram will be processed as soon as the data are available. The results will allow us to identify and interpret the deformation processes that have occurred on the peninsula over the past 12 days. We expected to publish the results tomorrow.

An episode of complex volcano-tectonic unrest is currently affecting the Reykjanes Peninsula. It is interpreted to result from multiple deformation sources at depth, which are interacting and affecting a wide area across the peninsula.

A powerful 6.3 magnitude earthquake struck western Afghanistan on Sunday, the US Geological Survey (USGS) said, more than a week after strong quakes and aftershocks killed thousands of people and flattened entire villages.

The US Geological Survey said the latest quake's epicenter was about 34 kilometers (21 miles) outside Herat, the provincial capital, and eight kilometers (five miles) below the surface. Also, a 5.5 magnitude aftershock has hit the area, said the USGS.

There were no immediate official reports of possible casualties or damage.

The earthquakes on October 7 flattened whole villages in Herat, in one of the most destructive quakes in the country's recent history.AP

A 6.3 magnitude earthquake has struck western Afghanistan, just days after a series of deadly quakes left more than 2,400 people dead.

The powerful earthquake struck an area near Herat, the capital of Herat province, early on Wednesday morning, local time.

There was limited information about the immediate impact of the quake.

The office of Herat's governor said there had been "huge losses" in districts near areas that had been flattened by earlier quakes.

Hawaii Volcanoes National Park has closed some parking areas and trails around Kilauea due to an increase in seismic activity. The U.S. Geological Survey reports the volcano is not erupting, but some elevated signs of unrest exist on its southern side.

The U.S. Geological Survey said it has detected an increase in seismic activity on Hawaii's Big Island that is associated with unrest of the Kilauea volcano.

The mountain is one of the most active volcanoes on Earth and has produced off-and-on cycles of lava since Sept. 29, 2021.

Volcanologists stress that despite hundreds of minor earthquakes, the volcano is not actively erupting. However, changes in terrain resemble periods with increased activity.
