Since the last statement, a total of 15 earthquakes have been located on the island of La Palma, none of them felt by the population.

The maximum magnitude registered is 3.4 (mbLg), corresponding to today’s earthquake at 07:04 UTC, at a depth of 39 km.

The seismicity continues under the central zone of Cumbre Vieja in the same zones of previous days, most of the earthquakes (13) are located at depths between 9 and 15 km, the rest (3) have been located at depths between 29 and 39 km. No earthquakes have been located at depths less than 9 km.

The amplitude of the tremor signal remains at low levels, with a slight increase in the last hours.

As in previous days, the network of permanent GNSS stations on the island does not show a clear trend in the deformation of the stations closest to the eruptive centers.

In the rest of the stations, the slight deflation possibly related to deep seismicity has stabilized, except in LP01, which continues to register it.

In view of the calibrated image at 08:45 UTC, an ash cloud height of 1,200 masl is estimated. in a south-southwest direction.

The height of the cone is measured , obtaining a value of 1,123 m. above sea level.
