Earthquake magnitudes, intensity, and quantity increase and deflation of the eruptive centre is observed.
Since the last statement, 72 earthquakes have been located in the area. The maximum magnitude recorded in this period is 4.3 (mbLg) corresponding to an earthquake that occurred at 03:10 UTC, located 35 km deep under the central area of the island, and that was felt by the population with a maximum intensity of IV (EMS). The mean amplitude of volcanic tremor continues in the mean range of values with respect to the observations measured during throughout this eruption, with some intensification pulses in the last hours observed in the low-frequency range. The height of the scattering cloud measured at 08:00 UTC is estimated to be 4,200 m. The island’s network of permanent GNSS stations does not show a clear trend in the deformation of the stations closest to the eruptive centres after the reversal that was recorded in recent days at LP03 (IGN, 2021). Lava fountaining continued today, and was accompanied by large blocks travelling down the advancing northern lava flows. The flow reached and then surpassed Montaña de La Laguna (GVP, 2021).
