Southwest deformation and deflation observed at GNSS stations
Rapid decrease in the number of seismic events but a high magnitude is maintained.
Lava flow causes confinements in Tazacorte.
Effusive/strombolian activity
Since the last statement, a total of 98 earthquakes have been located in the volcanic reactivation in the Cumbre Vieja area, six of them felt by the population. The maximum magnitude recorded is 4.8 (mbLg) corresponding to the earthquake felt with maximum intensity IV. In the period considered, 84 earthquakes have been located at depths around 30 km, the rest of the hypocenters of the period are located at a shallower depth, around 12 km. The amplitude of the volcanic tremor signal continues at lower middle levels with intensification pulses.
The island’s network of permanent GNSS stations shows slight deformation towards the southwest at station LP03, which is the 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 has registered it again.
In view of the image calibrated at 08:45 UTC, a column height of 3,700 masl is estimated , and a scattering cloud in the east direction.
