Mount Hakone's Eruptive History

6000 BCE Oldest radiocarbon dated eruption
1991 April - A swarm of earthquakes (more than 300) were recorded beneath the caldera. Some were just 5km deep and were felt by local residents.
2015 The alert level was increased (to Level 2) and a no-go zone declared. Japan's Meteorological Agency warned there was a risk of a small eruption. Hundreds of earthquakes were recorded along with deformation of the land's surface at the volcano. In June, sediment and debris ejected and formed a new fumarole. Ash was also released prompting the alert level to increase to Level 3.
