As of yesterday morning, the seismic activity has calmed down.
The swarm of earthquakes has been occurring about 8-11 km southwest of the caldera at depths between 1-4 km, in the vicinity of Pu‘ukoa‘e. The frequency of quake incidences is approx. 25-30 per hour.
During 07:00-10:00 AM local time yesterday, about 70 quakes have been detected with magnitudes ranging between M 1-3.
Some events are strong enough to be felt by local communities.
The summit region at the volcano continues to uplift at high levels.
Over the past months, the volcanic unrest has accelerated promptly, and an eruption could occur either with a short precursor or even without any warning.
