Recent earthquakes under Meakan volcano (JMA)
A swarm of shallow volcanic earthquakes under the Ponmachineshiri crater of Mt Meakan volcano has been occurring since yesterday. This event triggered the Japanese Meteorological Agency (JMA) to raise the volcanic alert status to 2 (eruption alert, on a scale of 1-5) today.
