Only in the early hours of this Sunday there have been more than 20 tremors, 18 of them in the municipality of Fuencaliente, more than two in El Paso and another two in Mazo.

In the last 48 hours, the IGN has located more than 200 earthquakes in the area affected by the volcanic reactivation of Cumbre Vieja, with at least 19 of them, he adds, felt by the palm population.

The maximum intensity corresponds to an earthquake that occurred at 20:54 UTC on the 9th, with magnitude 3.6 (mbLg) at a depth of 11 kilometers, reports the IGN. The largest earthquake located since the eruption began on September 19 took place at 23:55 on the 8th, with a value of 4.2 mbLg and 38 kilometers deep.

Of the earthquakes, about 40 are found at depths greater than 30 kilometers, and the rest, with hypocenters located at a shallower depth, around 12 kilometers.

The mean amplitude of the volcanic tremor remains stable in a medium range of values ​​with respect to the observations measured during this eruption and no intensification pulses have been recorded, explains the IGN.

Meanwhile, the height of the gas and ash column is 3,500 meters, showing a slight descent of the eruptive cloud.

On the other hand, the island’s network of permanent GNSS stations shows stability in the deformations of the stations near the eruptive centers.

The IGN adds that it continues to monitor the activity, strengthening the surveillance network and reinforcing its presence on the island, where the Eruption Attention and Surveillance Center has been established and work is carried out on a daily basis to collect samples of volcanic material. for on-site and subsequent analysis.
