This weeks one to watch -São Jorge Island (Azores) - Alert level orange
São Jorge Island (Azores)
An earthquake swarm started under the NW part of the island on 19 March 2022. More than 2000 mostly small quakes of magnitudes from 1.6-3.5 have been registered within the first few days of the activity.
The swarm is likely caused by a magmatic intrusion at 10-15 km depth and could indicate renewed eruptive activity in the future. There is also a risk of larger quakes occurring as the processes continue.
The seismic swarm under the island’s northwestern rift zone has decreased a lot during the past days, but it is still ongoing at lower levels.
Weak inflation also continued to be registered, which is why the official alert level remains at the second highest level of V4.
