. Thick lapilli layers (up to 1.2 meters near the vent) buried entire buildings and impacted roughly 1,200 hectares.

: Total pyroclastic volume reached roughly 45 million

Monitoring throughout the crisis revealed a complex plumbing system characterized by two primary magma storage levels: geological_impact_of_cumbre_vieja_volcano.7z

: The eruption produced silica-undersaturated rocks, specifically tephrites and basanites containing crystals of pyroxene, olivine, and plagioclase. Magmatic and Seismic Impact

of lava inundated over 1,200 hectares of land. Reaching the coastline at three locations, the lava constructed two new lava deltas (fajanas) extending into the Atlantic Ocean, adding roughly 50 hectares of new land to the island. Magmatic and Seismic Impact of lava inundated over

The 2021 eruption of the volcanic ridge on La Palma (also known as the Tajogaite eruption ) was the longest and most destructive historical eruption recorded on the island . Lasting 85 days from September 19 to December 13, 2021, the event fundamentally altered the island's topography and provided critical new data on magmatic feeding systems and volcano-tectonic deformation. Geological and Physical Evolution

The eruption transformed the western flank of La Palma through massive material deposition and structural changes: Lasting 85 days from September 19 to December

: The eruption built a new pyroclastic cone (Tajogaite) nearly 200 meters high from its base. Early in the eruption (September 25), the western flank of the forming cone partially collapsed, triggering a rotational rockslide and forming a U-shaped scar. Lava Flow and Deltas : Approximately 170 million
