6 cm uplift observed near the eruptive centre

6 cm uplift observed near the eruptive centre

End of eruption. Pyroclastic activity has ceased but low level seismic events continue.

Data type: Geological report
Groups: Seismic activity – Uplift – Volcanic cone measurement

Since the last statement, a total of 30 earthquakes have been located on the island of La Palma, none of them felt by the population. Magnitudes range from 1.3 to 2.5 (mbLg). The location of the hypocenters continues under the central area of ​​Cumbre Vieja in the same areas as in previous days; 4 shallow earthquakes have been located, 17 earthquakes at depths between 11 and 15km, and 9 earthquakes at depths greater than 30km. Likewise, low-frequency (LP) events continue to be detected in the records of the island’s stations, in addition to localized volcano-tectonic earthquakes. In the last 24 hours, no volcanic tremor has been observed, keeping the seismic noise at levels close to the pre-eruptive period. The island’s permanent GNSS station network shows an elevation of about 6 cm at station LP03, which is the closest to the eruptive centres. In the rest of the stations, no significant deformations that could be associated with volcanic activity were observed. Using a calibrated image IGN reports that at 08:45 UTC no type of emission could be observed. The height of the cone was measured at 1,122 masl (IGN, 2021).
