The National Geographic Institute (IGN) registered at 12.17 on Thursday an earthquake of magnitude 4.3 mbLg in Villa de Mazo at a depth of 35 kilometers. It is the largest earthquake recorded since the beginning of the volcanic eruption.
The wind pushes the ash cloud over the east and north of La Palma
He is not the only one registered on this day in which the island has not stopped shaking. During the first hours of this Thursday, more than 16 earthquakes were noted in the area of Cumbre Vieja, five of them with magnitudes greater than 3 (mbLg).
The maximum magnitude recorded was 3.5 (mbLg) corresponding to the earthquake located southwest of the municipality of Villa de Mazo at 01.33 hours. Most of the earthquakes were located between 11 and 14 kilometers deep in the area where the swarm began.
Specifically, from 1 a.m. on Thursday, October 7, until 11.17 a.m., 53 earthquakes have been located in the southern part of the island, ten with a magnitude between 3.1 and 4.3. All have been detected in the municipalities of Fuencaliente and Villa de Mazo at a depth of between 10 and 35 kilometers, although the vast majority are between 10 and 14 kilometers.
Compared to Wednesday, the aforementioned number of earthquakes represents an increase.
This Wednesday more than fifty earthquakes were located, the largest of 3.7 mbLg, felt with intensity of III EMS in numerous centers of El Paso, Villa de Mazo, Breña Baja, Los Llanos de Aridane, Breña Alta, Santa Cruz de La Palma, Tazacorte and Puntallana.
The volcanic situation remains “stable”
The situation has been stable in recent hours. The volcano exhibits constant behaviors, the lava flows through a single stream in a fluid way and the lava delta continues its growth in a north-south direction with an area of almost 38 ha.
A lava tube has been formed that allows a more fluid contact between the emitting center and the dejection area, in the sea, which ensures that the width of the casting does not increase and therefore does not affect more constructions. The area affected by the runoffs is almost 422 hectares.
Although the number of earthquakes and their magnitude have decreased in recent hours, there are still movements felt by the population and that could cause small landslides of the wash in sloping areas.
On the other hand, the emission of volcanic ash reaches a height of 3,000 meters and the wind directs it towards the northeast. Due to the presence of ash, several companies have decided to cancel their operations on La Palma for today, although the airport remains operational and will continue to be as long as there is no ash precipitation that cannot be cleaned.
