The seismic crisis started at 4:33 am local time (12:33 am UTC) on 18 Oct 2021 stopped, the volcano observatory reported yesterday evening. The magma intrusion that took place at shallow depths beneath the Plaine des Osmondes in the northeastern part of the caldera no longer seems to be progressing.
Apart from a small magnitude M1.9 earthquake at 10:51 (local time) located 1.4 km below sea level, no earthquake of magnitude above 0.5 has been recorded at the volcano yesterday. This means that the recent magma intrusion is no longer moving, but it is only a matter of time until a new one starts, possibly then followed by an eruption.
It is also possible that the recent magma intrusion resumes at any time.
