LA PALMA FIELD TRIP 2016

From the 2nd to the 9th of April 2016, some members of the VeTOOLS project from CSIC group (Joan Martí, Stefania Bartolini and Laura Becerril) and FCUL group (António Brum da Silveira) went to La Palma (Canary Islands) with the aim to better understand the behaviour patterns of the past historical eruptions.

La Palma is the north-western most island of the Canaries. It is the second youngest island of the archipelago, with an age of about 2 Ma and, it can be considered the most volcanically active island since seven volcanic eruptions have been occurred in the past 600 years (historic period). These eruptions took place in: 1430-40, 1585, 1646, 1677, 1712, 1949, and 1971 and are located at the south half part of the island, in Cumbre Vieja Volcano.

During the trip we mainly analysed the volcano-structural configuration of these historical eruptions in order to get the needed data for conducting the spatial probability map of the island. We mostly focused on the volcanic vents and the eruptive fissures formed during the eruptions, paying special attention to the number of structures and their orientation. We also recognised the main deposits of the eruption and compared their morphologies and the size of the main cones. We got information related to lava flows such as the lengths and thickness required for developing volcanic eruptive scenarios.
