The restrained Icelandic volcano Fagradalsfjall on the Reykjanes peninsula stepped into the spotlight on the evening of March 19, 2021, when an eruptive fissure opened in the Geldingadalir valleys.
It had been quiet for over six thousand years, and is the first active volcano in the Reykjanes UNESCO Global Geopark area for 800 years…
Three weeks prior to the volcanic outbreak, an intense earthquake episode began on the Reykjanes peninsula near Fagradalsfjall mountain. It started with an M5,7 earthquake that stirred people in large parts of Iceland…
The earthquakes finally stopped, and everything was quiet for three days. But on a Friday evening, at 20:45 on March 19, 2021, people in Grindavík town and elsewhere on the Reykjanes peninsula reported a glowing light in the sky. No eruption tremor was detected, so the only way to confirm if an eruption had started was to have a look.
The eruption has been described as a “tourist eruption,” a term commonly used by Icelanders for minor eruptions that can easily be accessed. Of course, the usual thing to do when a volcano erupts is to get as far away as possible. But in Iceland, the “usual” response is the opposite. So Icelanders started flocking to the eruption site to look at the spectacular show nature was offering.
As noted any chance I get, Iceland is one of my favorite places on Earth. For obvious geophysical reasons, for the friendliness and openness of Icelandic culture. Get a chance? Go and visit.

Heavy rain triggered Indonesia’s volcano eruption. This could happen more https://www.cnn.com/2021/12/08/asia/indonesia-mount-semeru-volcano-eruption-cimate-intl/index.html
The role of rain in this case has raised questions around whether climate change could bring more frequent eruptions of this kind. That’s a concern, because eruptions caused by lava-dome collapse tend to be stronger and more destructive than other types, scientists told CNN.
Continued global warming is projected to bring more extreme rain events to many parts of the world, raising concerns that these larger eruptions could come with little or no notice at all.
Scientists don’t know this is necessarily going to happen, but more have been asking that question since 2018, when Hawaii’s Kīlauea volcano erupted after days of heavy rainfall.
“People have been thinking about the relationships between climate and triggers of volcanic eruptions,” Handley said.
“There’s still a lot to explore that we don’t know yet, so but it’s good to think about other external driving mechanisms of volcanic eruption that we might otherwise have missed.”
