- 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.

This is a good link to Icelandic seismic activity, DrM:

Burned my boots on Hekla lava in 1969!

Yes that is the most reliable source of info.
Re. Hekla, I won’t pretend I’m not jealous.

Those were the days where you sailed from Leith, DrM on the MV Gullfoss. It was a choppy crossing. When we set out back to the UK there were 2 drunk sailors flat on the deck. One groaned and his mate held a bottle of Brennevin in his mouth for him.

I’d have been like that on that crossing without the alcohol.

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.

In fact at the time of writing the live camera feed looks quite active too.

Things are ramping up in SW Iceland:-

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?

---

Aviation is buggered anyway, so let it blow with northerly due as well!

Iceland metoffice have confirmed a magma intrusion.. could something interesting finally be about to happen again in the land of fire & ice.

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

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.

Magma movement confirmed under Reykjanes Peninsula!

Icelandic effusive types are notorious for toxic gasses so given the location there is definitely a risk to health for many Icelandic folk should this erupt.

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.

Edit: There is some impressive footage of the ash cloud here: https://youtu.be/HzwuTBx93uA 

---

Tremor pulse has now been detected in the area Keiler and the aviation colour code for Krysuvik has now been changed from yellow to orange (

meaning: " Volcano is exhibiting heightened unrest with increased likelihood of eruption  or, Volcanic eruption is underway with no or minor ash emission."

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

Etna is looking very lively this morning:

So no possibility of journeying underground from Snaefel to Stromboli this year, DrM?

Impressive as it is is that really live as it states or a rolling repeat?

The Skyline ones seem far less boisterous at this moment.

Compare.

You're right, I think it may now be on a loop but it was definitely very lively this morning and at the time of posting the webcam link that you posted was actually showing something quite similar to what is seen in the YouTube video. It is quieter now by the look of things.

 

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.

---

Yes it's not showing LIVE any  more.

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:

https://www.goodreads.com/book/show/880.Pompeii

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