She's properly ramped up tonight.

Seems there's 4 vents now, 2 shooting lava straight up on the main cone with a 3rd that seems to be spewing all the lava flows and there looks to be a 4th vent further back on the hill I wonder if this will create a new cone

Mt. Aso, joins the game today.
They are warning at La Palma earthquake activity could ramp up to as much as a 6 - largest so far IIRC 4.8.
While still a long way from the kind of energy needed where a major landslide risk becomes real, minimum likely required ~7.8-8.0, that is not good news in that direction.

6 to 8 is circa 100 times the energy isn't it?
Dunno off the top of my head but the scale works something like that. For a serious flank collapse like scenario at the island most of the studies show it would need an earthquake, in the right place, with more than 1000x the energy of any earthquake there so far which is around 100x higher on the earthquake scale (around 7.8-8). Even then it doesn't mean the flank collapse would happen in a manner which produced a megatsunami.
Soldato
Yeah. An increase of 1 on the Richter Scale (say 4.0 to 5.0) equates to 10 times the energy released. An increase of just 0.2 doubles the energy released, so a 4.2 quake releases double the energy of a 4.0

Yes I've been watching this guy on youtube, he has clickbait titles but his actual videos are quite reasonable just giving updates on the island and what the news reports have been saying, sounds like they're expecting it to get worse before it gets better

I hope Tazacorte escapes from the path of lava flowing from La Laguna, was hoping it would via towards Mt La Laguna and out into the atlantic.

I'm not sure the link but for some reason volcanic activity always seems to pick up as we come out of the minimum part of the solar cycle - not to say anything is imminent or inevitable but some of the biggest eruptions in modern history "coincided" with similar phases of solar activity as we are going through now such as 535-536 and 1815.
