Since 12 noon yesterday (09/25/2021), 4 earthquakes with magnitudes between 2.3 and 2.6 (mbLg) and depths between 8 and 13km have been located at the base of the intrusion that preceded the volcanic eruption. The amplitude of the volcanic tremor at low frequencies (0.5-0.7Hz) have decreased considerably in all the stations of the island as of 12h yesterday.

This video shows a short cell phone recorded clip, from the 26th of September, of the explosive behaviour at one of the vents. Sourced from IGME (2021).
