The first underwater images of the fajana that is being formed on La Palma


Underwater image of the lava delta that the eruption of La Palma is forming on the coast of Tazacorte.

The Institute of Oceanography and Global Change of the University of Las Palmas de Gran Canaria (ULPGC) has managed to record for the first time underwater images of the fajana that the eruption of La Palma is forming on the coast of Tazacorte.

As reported by the ULPGC, the images have been captured by the investigators from the Quima group, specialized in acidification of the marine environment, with the collaboration of the Canarian company Ecos (Environmental Studies and Oceanography).

The result of this work has been made available to the Canary Islands Special Volcanic Risk Protection Plan (Pevolca) so that experts in geology and volcanology “can get the most out of it in terms of managing the volcanic crisis.”

“They are very useful images to understand the impact and evolution of the wash when it reaches the sea, which are complementary to the measures that the Quima group has been carrying out in the area since the beginning of the eruptive process”, their authors assure.

This research group continues to monitor carbon dioxide parameters (pH, alkalinity, inorganic carbon) and other chemical-physical parameters, in addition to taking samples for the biogeochemistry of iron.

The images have been recorded using an underwater robot and a 360-degree camera on the southern, western (front) and northern flanks of the lava delta.
