Vertical uplift observed, but not quantified, close to the eruptive centres.

Rapid decrease in the number of seismic events but a high magnitude is maintained.

Since the last statement, a total of 44 earthquakes have been located in the area, 5 of them felt by the population. The maximum magnitude recorded is 4.8 (mbLg) corresponding to yesterday’s earthquake at 22:40 UTC, with a depth of 37 km and intensity IV-V. The seismicity continues under the central area of Cumbre Vieja the same areas of previous days, most of the earthquakes are located at depths 10-15 km and only 7 of them at depths greater than 30 km.The amplitude of the volcanic tremor signal continues at low average levels with fluctuations coinciding with the effusive episodes observed during yesterday.

GNSS stations shows vertical uplift movements at the stations closest to the eruptive centers, the magnitude of which is yet to be confirmed due to adverse
weather conditions. 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 image calibrated at 07:36 UTC, a column height of 3,500 masl is estimated , and a scattering cloud in the east direction. The height of the cone is measured obtaining a value of 1,126 m. above sea level.
