- The seismicity during the past month has been above average
- Geothermal activity has increased over the past months with clear signs of deepening cauldrons in several places around the caldera
- The surface deformation has exceeded the level it was at prior to the 2011 eruption
- Magmatic gases were measured in the geothermal emissions this summer.

Mount Ile Lewotolok in Indonesia has erupted. There is some impressive footage of it around:

I'm not sure if this should be in the earthquake or the volcano thread but either way it has been a very seismically active afternoon in SW Iceland today (on the Reykjanes peninsula) with a magnitude 5.7 quake and numerous aftershocks above magnitude 3. This area was also very active at times last year, so I suspect it will be being monitored very closely.

No mention of the huge lava fountains that Etna has (briefly I think) been producing recently? Ok, I think it was what the call 'strombolian' activity but if that's what it was  is was seriously strombolian!


Some good vids on you tube.

A little of topic, but as Mars has been on the news recently, thought it'll be interesting to note that it has no active volcanoes there today.

Yes, it is still very lively there in terms of quakes. I wonder if or how things will develop. Is there a chance of a rifting episode?

If an eruption take place here it's likely to be more of a lava flow than anything sky high.


https://www.mbl.is/frettir/innlent/2021/03/02/eldstodvar_gusu_ofan_vid_hvassahraun/


The next eruption on the Reykjanes peninsula will most likely be a lava eruption. This can be accompanied by volcanic eruptions and some explosive activity in craters, which will probably be on the weaker side compared to previous eruptions on the Reykjanes peninsula.


"We find no signs of a large eruption on the Reykjanes peninsula. There have been volcanic eruptions, but they are usually very local. An eruption that took place there in the 13th century sent off some volcanic eruptions. The medieval layer that came from it is a few centimeters where it is thickest in settlements. Now we are primarily looking at lava flow if it erupts and I think that will be the main effect of an eruption on the Reykjanes peninsula, "said Þorvaldur. He said that such an eruption could be accompanied by a volcanic eruption, but that it is unlikely that it will destroy local communities.

Etna continues to erupt ..  https://www.euronews.com/2021/03/02/mount-etna-europe-s-most-active-volcano-erupts-seven-times-in-two-weeks.


I also note there are a fair amount of volcanic activity across the world , Of course on a world scale   It is the ones that eject a large amount of ash into atmosphere that can make a difference to the climate rather than local lava flows..

Yes, Mount Sinabung in Indonesia also erupted with dramatic (but thankfully limited) effect over the past 24 hours.

There is no confirmed eruption but the likelihood seems to be increasing.

Meanwhile in SW Iceland, things still look very seismically active but I haven't seen any further IMO updates yet today: https://en.vedur.is/earthquakes-and-volcanism/earthquakes/reykjanespeninsula/ 


Aviation code is still orange and the ground seems to have dropped in one area.

A read on Iceland's Laki eruption and its effects around the world with first hand accounts though perhaps not for the the faint hearted.

And heading off to Italy for a fictional account of another famous eruption:

You can really feel you are there on the ground as well.
