New field techniques investigated: A group of GeoIntern students from GeoTenerife under the leadership of Professor David Foster and postgrad student Danilo Cruz of the University of Florida have been testing a portable XRF on the flows of Tajogaite volcano to assess its potential for rapid use in the field to identify trace elements in the lava which could help scientists to acquire reliable data on eruption evolution.

After the declaration of the end of the eruption on the 25th, monitoring still continues as the focus now turns to disaster recovery. PEVOLCA is keen to note that volcanic dangers still persist in this phase and the red traffic light remains in force, so the population must respect the exclusion zones and civil protection measures. 

The return of 7 families to the Los Lajones neighbourhood in Puerto Naos has been authorised by the government, with systems including PA systems and phone alert systems put in place in case the gas levels reach dangerous levels. Elsewhere, some platforms of affected people have protested and produced a report arguing for the return of all residents and the reducing of the Volcanic Traffic Light Alert System from Yellow to Green.

The gas levels in La Bombilla and Puerto Naos continue to show little sign of improvements, with gas monitors belonging to INVOLCAN exceeding 50,000 ppm of CO2 daily inside buildings in some areas. Further meetings are taking place to attempt to determine a pathway for improved access to the area, and plans are underway to restore water to La Bombilla and Puerto Naos.
