I posted about seeing the La Palma volcano on a cruise in November.  We did another cruise last month and actually visited La Palma.  It’s a beautiful island and thankfully, the only sign of damage is a dusting of black ash everywhere.  When we saw the volcano, we were on a cruise that should have gone to The Azores but didn’t due to Covid, which was a bit disappointing as I’ve never been there, but it couldn’t be helped.  We’re supposed to be on a cruise next month which includes The Azores!  Hmmm!  

The estimated amount of magma that has accumulated so far is around 20 milllion cubic meters which is almost double of what La palma had last year.

Yes, it’s still very active and uncertain!

It still looks like they have magma movement but I haven’t seen any further news. I’ve booked our cruise, which still has two islands of The Azores on its itinerary on 4th and 5th May.  I wonder if we’ll make it this time?

I think it might be a while longer but it would seem a large amount of magma is involved. Personally i would rather it happened in summer time as it would mean a greater chance for us of seeing some nice volcanic sunsets.

  Although I think the islanders would rather it happen sooner, if at all.  What would be the chance of us seeing another volcano erupting?  I thought seeing one, was a lifetime opportunity.  It was amazing, although I felt a sense of guilt being a sightseer, when lives and livelihoods were at risk. A bit like ambulance chasing!

We’re back from our cruise and had two days in the Azores.  We saw and heard absolutely nothing about the earthquakes or the recent worry about eruptions.  The news seems to have stopped coming as well, so maybe it’s calmed down.

the atmospheric effect of the eruption of the Tonga Volcano in January has now been analysed in more detail and has been found to have had the biggest effect on the atmosphere since at least the start of the 20th century and on a par with Krakatoa in 1883

Worth a read, Lanky.

"The eruption of the Tonga volcano in January has been confirmed as the biggest explosion ever recorded in the atmosphere by modern instrumentation....  It was far bigger than any 20th Century volcanic event, or indeed any atom bomb test conducted after WWII."

p.s.

p.s. The lunar eclipse [tonight]  could be a deeper darker red than usual because of lingering exhaust from the Tonga volcano.

Hopefully it will stay clear in places for the eclipse later tonight.. The scale of the Tonga eruption is incredibly impressive and we are “lucky” that it wasn’t somewhere more densely populated.

On a different, but volcanic-related note, things are looking quite active seismically in SW Iceland over the last few days. Not sure of the cause as yet but worth keeping an eye on.

The SW Iceland thing is (at least in part) more magma accumulating at depth by the looks - whether this particular intrusion makes it to the surface is debateable but has the potential to be somewhat more disruptive given current uplift centre is not that far from Grindavik. 

On the Tonga front this was quite an interesting watch:-

On the subject of the Tonga eruption, the BBC have an interesting report on how (surprisingly) intact the volcano still is: https://www.bbc.co.uk/news/science-environment-61529290

Quite surprised by that - was expecting at least a fair chunk of the volcano to have slipped away to account for the tsunami generated.

On the subject of the Tonga eruption it has now by the looks of it been classed as VEI 6.

6.5 cubic km of ash and rock was ejected and the base of the caldera has now gone down to 850m below sea level

I am just wondering whether we will see a dip in the global temperature over the next year as we did with Pinatubo in 1991

Probably not as the SO2 was relatively low most probably because the sea caught it

We've already seeing record heatwaves in Asia and Spain. Will lead to crop failures and food shortages

This year could be the hottest so far and accelerating past the tipping point

Has anyine been watching "Exploration Volcano" on Dave

3 episodes so far covering La Palma, Congo and Sicily

I like the style of the explorations leader (Chris Horsley) and he has been getting some fantastic pics and videos of volcano crater rims that you don't normally get to see

I suspect he is a bit of a nutter though. This week he was trying to collect newly emitted magma from Mount Etna (still hot at 500C on the outside) for analysis in the local geophys lab
