SANTA CRUZ DE TENERIFE, Oct. 13 (EUROPA PRESS) –
The 24-hour monitoring volcanic surveillance network of the National Geographic Institute (IGN) has located a total of 20 earthquakes in the vicinity of the eruption of the Cumbre Vieja volcano, 6 of them with magnitudes greater than 3 (mbLg).
The maximum magnitude recorded was 3.9 (mbLg) corresponding to the earthquake located southwest of the municipality of Villa de Mazo at 04:22 hours. With intensity III EMS and a depth of 37 km, it was felt in Los Llanos, El Paso, Breña Alta, Tazacorte, Tijarafe, Breña Baja, Santa Cruz de La Palma, Garafía and Puntagorda.
Yesterday 74 earthquakes were located, the largest of 4.1 mbLg, located southwest of the municipality of Villa de Mazo at 08.25 hours. With intensity III-IV EMS and a depth of 37 km, this tremor was felt in almost the entire island.
As a consequence, last Saturday, from the collapse of the volcano cone, the lava flow is undergoing variations. So far there are three streams: the one that runs further north yesterday forced the preventive evacuation of 700/800 people; the other two languages, the original one barely has a lava contribution and the second, further south, affects new constructions within the security perimeter.
The meteorological conditions yesterday favored the improvement of air quality, which allowed the lifting of the confinement of 3,500 people decreed last Monday. The airports of the Canary Islands are still operating, although the airlines are canceling operations to La Palma. The ash emission height reaches 3,500 meters and they move from the west turning east and south.
Seismicity continues with a depth of between 4 and 35 km and a maximum magnitude of 3.6. The volcanic tremor signal has increased, which could indicate higher gas content in the magma coming out of the eruptive center.
