The National Geographic Institute (IGN) detected this Thursday between 04:00 and 07:20 (UTC) an abnormal microseismic activity in Las Cañadas del Teide, with at least 500 earthquakes detected in the same area in which in recent years swarms have been recorded.
This abnormal microseismic activity was located southwest of Pico Viejo, where seismic swarms have already been recorded in October 2016, June 2019 and June and July 2022, as reported by IGN.
The activity began with a series of 10 earthquakes of magnitude less than 1.1 (mbLg) between 8 and 12 kilometers deep in the area, followed by long-duration signals, without defined seismic phases and with content at high frequency.
This resulted in a long series of hundreds of small and similar events, occurring at almost regular time intervals, in the form of a “drumbeat”, as IGN puts it.
Due to the weakness of the seismic parameters recorded, earthquakes of lower magnitude were detected by the automatic system, but they are not located with sufficient quality to be included in the official IGN catalog.
IGN indicates that it will continue to monitor activity in this area.
