Earthquakes around the world

[Aeneas]

It would be good to stick to earthquakes in this thread @Border Dog and @Luks , so as not to make it into potpourri of topics which belong in other threads. If a topic which you like to discuss is not found elsewhere, then start a new thread to discuss it.

Earthquake overview

The ongoing eruption on Iceland’s Reykjanes peninsula is likely the beginning of a long period of intermittent volcanic activity in the area, according to Geologist Páll Einarsson. “I think that’s the conclusion we have to make, it’s very likely,” Páll told Iceland Review. “Volcanic activity has begun after a long pause, that is likely the beginning of a volcanic period that can last for quite a long time, especially if we look at the history of the past few thousand years, this volcanic activity appears to come in waves.”

On February 24, 2021, an earthquake swarm began on Reykjanes with an earthquake of magnitude 5.7. Scientists soon deduced that magma was flowing into a passage some 1-2km [0.6-1.2mi] below the surface of the Reykjanes peninsula and could result in an eruption. On March 19 around 8.45pm, the eruption began.
