It is the first eruption since 1971.
LA PALMA, Spain, Sept 19 (Reuters) – A volcano erupted on the Spanish Canary Island of La Palma on Sunday, sending lava shooting into the air and streaming in rivers towards houses in two villages from the Cumbre Vieja national park in the south of the island.
From The next Grand Solar Minimum, Cosmic Rays and Earth Changes (an introduction), “As a further complication in a Grand Solar Minimum, cosmic rays that make it to Earth and enter the surface, can trigger earthquakes and volcanoes and other tectonic anomalies. The penetrating particles (cosmic ray muons) from space decrease the viscosity of silica-rich magma. See: “Explosive volcanic eruptions triggered by cosmic rays: Volcano as a bubble chamber.”
Geologists have warned for decades that there is a small chance that a destabilisation of the Cumbre Vieja will at some point in the next few Millenia cause a landslide that will trigger a mega tsunami a hundred foot tall to annihilate the west coast of the American continent. There is no indication of any such crustal destabilisation in the current eruption.
