Giant lava fountains, very violent activity after partial cone collapse at Cumbre Vieja, La Palma

Giant lava fountains, very violent activity after partial cone collapse at Cumbre Vieja, La Palma

A partial cone collapse at Cumbre Vieja volcano at 08:25 UTC on October 25, 2021, exposed giant lava fountains with large emissions of gasses, ash, and lava. This was followed by very violent explosive activity starting around 13:30 UTC and the opening of a new vent with an impressive lava overflow at 14:00 UTC. The events were preceded by a significant increase in intermediate and deep seismicity on October 24, with an increase in magnitudes in the intermediate zone.

274 earthquakes have been located in 24 hours to 08:00 UTC today. 24 of these were felt by the population. 110 had a magnitude equal to or greater than 3.0 mbLg and 4 of them had a magnitude of 4.0 mbLg. 

Only 3 quakes have been located at depths around 30 km (18 miles), with the rest located at shallower depths of around 12 km (7.4 miles).

The amplitude of the volcanic tremor signal has increased considerably, with numerous intensification pulses.

Giant lava fountains were observed after a partial cone collapse at 10:25 UTC on October 25, followed by a large emission of gases, ash and lava. 

The volcano entered a phase of very violent explosive activity in the central went around 13:30 UTC.

A new vent has opened at 13:45 UTC and was followed by an impressive lava overflow at 14:00 UTC.

Events described above are chronicled in the videos below:

Since September 11, earthquakes located beneath Cumbre Vieja have released an amount of energy equivalent to 500 tons of TNT. As a reference, the nuclear bomb that destroyed the Japanese city of Hiroshima had a power of 15 000 tons of TNT.

The location of earthquakes has not changed significantly over the past few weeks, suggesting that a scenario in which the magma was attempting to move another way and open other eruptive centers far from the current one is highly unlikely.

THE CURRENT ERUPTION OF LA PALMA VOLCANO IS ONE OF THE ABSOLUTE PROOFS OF MY PHYSICS THEORY...........Over the past 10 years, I have written huge amount of material about the true causes of the massive Earth changes and why the changes will increase substantially. However, the central issue in my arguments about the cause of climate change is the heat increase at the interior of the Earth. And, I am arguing vigorously that the heat increase at the interior of the Earth is not only the reason for most of the Earth changes that we are witnessing right now, but also the reason for the rapid shift in Earth's magnetic poles. Nevertheless, all volcanoes that are linked to the upper mantle will soon start erupting violently, just like La Palma

The Cumbre Vieja is an active volcanic ridge on the island of La Palma in the Canary Islands, Spain. Not to be confused with the Cumbre Vieja volcano of Nebraska. :)
