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. |
2019 | The alert level has been lowered to Level 1 after seismicity decreased. |
