Reversal of vertical and westward deformation observed near the eruptive centres in the past few days
Rapid decrease in the number of seismic events but a high magnitude is maintained.
Since the last statement, 52 earthquakes have been located in the area, four felt by the population. At 10:19 UTC yesterday, an earthquake of magnitude 4.6 mbLg was registered at a depth of 37 km, and felt by the population with maximum intensity of IV-V. Hypocentres continue to have two groups of depths one between 10-15km and another around 30 km deep below Cuymbre Veija. The tremor signal continues in a range of low values with fluctuations in the last hours.
The island’s network of permanent GNSS stations shows a complete reversal of the elevation recorded between November 17 and 19, partial reversal in the westward deformation and consolidation of the southward deformation at station LP03, which is the closest to the eruptive centers.
