Since the last statement, 72 earthquakes have been located in the area, seven of them felt by the population in the epicentral area. the largest earthquake has been recorded at 03:37 (UTC) today and corresponds to an earthquake of magnitude 5.0 (mbLg) that has been felt with a maximum intensity of IV-V ( EMS) . This earthquake has been followed by a dense swarm of earthquakes. It is noteworthy that most of the activity recorded in the last 24 hours is located at depths greater than 30 km under the central area of Cumbre Vieja. The tremor signal continues to remain at low values, with a significant  intensification episode between 03 and 04 UTC, coinciding with the swarm of deep earthquakes. The island’s network of permanent GNSS stations shows that after reversing the elevation of days 4 and 5 in station LP03, which is the closest to the eruptive centers, it remains at a lower level than previously established. On the other hand, the southwest deformation registered in the station still continues In the rest of the stations, the slight deflation possibly related to deep seismicity has moderated.
In view of the calibrated image, a column height of 2,500 m is estimated at 08:45 UTC . above sea level
