Hi Michael.  I’ve been following the eruption fairly regularly on a couple of YouTube channels over the last few weeks. That new vent is causing concern because of the rate of flow and the risk of the lava stream causing new damage. 

Apparently there has been another increase in the number of earthquakes.

Yes, that vent is certainly causing problems I think. Remarkably (based on previous events) the eruption doesn’t show any really signs of stopping in the immediate future.

This is an impressive video of the new lava flow:

Yes, that is impressive.  On a YouTube video I saw last night it was described as being like a waterfall, with very fluid lava flowing down.

---

A whopping 371 earthquakes in the last 24 hours on La Palma, following 250 in the previous 24 hours.

 

---

There is an ongoing glacial flood at Grimsvötn in Iceland currently and the glacier above the volcano has subsided by over 38m in the last week or two. Whether this is a precursor to an eruption remains to be seen, but it is a possibility.

---

Water plus eruptions always a concerning prospect DrM! We will need to keep an eye on this one. We know about Grim in Lincolnshire!

A big eruption of Semeru in the last few hours on the eastern side of Java. Reports of the ash cloud hitting between 40,000 and 50,000 feet. 

That looks like a really big eruption based on the video footage.

Very little information about it. The only reason I know is through a friend in Jakarta on Facebook.

Reflecting on the recent newsworthy volcanic eruptions mentioned above I did some [rather unproductive] searching for recent research on the impact of volcanic dust on climate. I did however encounter an intriguing paper on the correlation between Volcanic impact and political upheaval which I feel sure some posters will enjoy thinking about:

"State or societal collapses are often described as featuring rapid reductions in socioeconomic complexity, population loss or displacement, and/or political discontinuity, with climate thought to contribute mainly by disrupting a society’s agroecological base."

Volcanic climate impacts can act as ultimate and proximate causes of Chinese dynastic collapse

I’m keeping a very close eye on Iceland this morning as there is a very large ongoing swarm of activity where the earlier eruption was. There could be a new event very shortly.

---

Hadn't spotted that, ty for the heads up

Certainly a rather dramatic uptick in tremor:-

Existing crater has some smoke/steam rising although not sure that's unusual as it's been doing that since the eruption stopped, presumably just latent heat.

MDL Iceland cam caught a small tremor at the Geldingadair volcano just after 3pm today:


You can even see a few rocks being shaken out of place on the volcano itself.

Just caught this on the news, Hunga Tonga-Hunga Haʻapai eruption;

https://www.bbc.co.uk/news/world-asia-60007119

Some of what is being reported in terms of where impacts are being felt is astonishing (e.g sounds of the eruption being heard over 500 miles away).

 

Ash cloud of 100,000 feet? As being reported over here in Australia. That’s a very large eruption.

The footage shows it is a very powerful eruption. The satellite imagery is remarkable:

Short clip here - impressive and frightening. There is a lot of low land in Tonga and many people could be affected.

The pressure wave was detected as it passed over Auckland, with a 4mb pressure blip. That’s 1,250 miles away.

I wonder what the VEI is for the eruption?
