Alert: Volcano eruption in La Palma could result in mega-tsunami

In Theory any flow of Lava to the surface of a volcano releases pressure so yes "but" theirs always a "but" when the magma /lava removes itself from where it once was it either draws more lava from somewhere else to fill the void, now the problem is the lava/ magma is creating more voids which can or should cause earthquakes ...hope that makes sense

 

La Palma volcano eruption update: new cracks open at cone generating new lava flows

With the eruption approaching two weeks of activity, there is no sign of it ending anytime soon. Instead, the magma supply rate seems to be more or less stable, judging from visible lava output and volcanic tremor, which remains at high levels.
The cone complex above the original eruptive fissure is showing signs of becoming more and more unstable, as several new effusive vents have been opening up during the past 12 hours or so.
At 10.15 a.m. local time this morning, observers on location reported seeing new gas and ash emerging from what is likely another vent forming at the NW base of the cone, visible in the attached pictures by the bluish haze behind the tree line, obviously coming from an area at the feet of the cone.
Over night, ash fall affected a wide area to the north of the site. It left a deposit of at least 1 cm in El Paso, but even in 15-20 km distance, a black layer of sandy ash has covered surfaces, forcing people to constantly clean roofs, solar panels and other surfaces.
Lava continues to flow into the ocean - risk of collapse increases
The new lava delta on the west coast near Playa Nueva has been growing surprisingly quickly, as the embedded bathymetric map shows:
Once the delta expands further westwards, it will be sitting on steeper underwater slopes, and the risk of gravitational collapses increases. Such collapses can be very dangerous as they usually trigger strong explosions, large acid steam plumes and could even generate small local tsunamis.As the situation is quickly evolving, we will likely post another update in the evening.

 

Warning.......

My above post from volcano discovery contains vital info that needs to be considered and watched over the next few days Ive copied and pasted them below......

yes Indy this is the first time that the volcano guys have actually gone public with what I and Brian mentioned last week that is the lava reaching the sea and weakening or unstabling the shelf below...we have got to remember its what lies beneath the water line is the most dangerous the volcano is only the tip of the iceberg

 

To explain a little bit clearer on my thought pattern, when the studies where done back in 2000 and they noted the western flank being unstable a lot of science was placed on possible eruptions earth quakes etc what wasn't looked at was lava flow increasing weight to an already unstable shelf and tipping the scales, pulling said shelf away from the cliff face.. a bit like a bus hanging over a cliff..

 

Cant call that at all mike but the new delta is growing fast and expanding in the direction of danger..

 

I hear you Indy...after all the recent forest fires etc and now this eruption its hard not to compare it to the four trumpets...Heaven help us...


Then the first angel sounded his trumpet, and hail and fire mixed with blood were hurled down upon the earth. A third of the earth was burned up, along with a third of the trees and all the green grass. Then the second angel sounded his trumpet, and something like a great mountain burning with fire was thrown into the sea. A third of the sea turned to blood, a third of the living creatures in the sea died, and a third of the ships were destroyed
