A seismic swarm, characterized by 31 shocks in 42 minutes, struck the upper zone of the eastern rift of Kilauea on 5 March a little before 6 am local time.
The largest earthquakes had magnitudes between 1.7 and 3.9 and a depth of one to two miles below the surface.
According to the experts, the localization and the importance of the sequence suggests a link with the pressurization of the magmatic system under the summit of Kilauea. However, these earthquakes did not cause any changes in the current eruptions, no surface deformation or cracks.
