An earthquake swarm occurred at Kilauea in Hawaii. It put the HVO volcanologists on alert and the alert status was raised from “yellow” to “orange”.
The swarm now comprises more than 140 quakes. In addition, an intensification of the ground deformation was measured with the onset of the swarm quake. It confirms my earlier suggestion that a magmatic dyke is intruding into shallow areas beneath the crater. The probability of an eruption in the area of the summit caldera increases.
