Can Mount Fuji still erupt 2024?

As a geologist with a keen interest in volcanic activity, I have been closely following the geological history and current signs of volcanic activity around the world, including the iconic Mount Fuji in Japan. Mount Fuji, standing at 3,776 meters, is not only Japan's highest peak but also an active stratovolcano. Its majestic presence and historical eruptions have made it a subject of fascination and concern for both the scientific community and the general public.

The last eruption of Mount Fuji, as you mentioned, occurred in 1707, known as the Hoei eruption. This event was preceded by a significant seismic event, the Hoei earthquake, which provides us with a crucial insight into the potential triggers for volcanic activity. The relationship between earthquakes and volcanic eruptions is complex and can be indicative of the movement of magma beneath the surface, which could lead to an eruption.

Recent studies and monitoring efforts have been focused on understanding the subsurface structure of Mount Fuji and the potential for future eruptions. Seismic activity, gas emissions, and deformation of the volcano's surface are all critical indicators that are closely monitored. While there has been no eruption since 1707, the signs of unrest can vary and are not always clear indicators of an impending eruption.

It is important to note that predicting volcanic eruptions with precision is an ongoing challenge in the field of volcanology. The timeframe for when Mount Fuji might erupt again is uncertain, and it is influenced by a multitude of factors, including tectonic activity, magma chamber dynamics, and external triggers such as earthquakes.

The potential impact of an eruption on the surrounding areas is significant. A government study, as you've referenced, has estimated that an eruption on the scale of the 1707 event could displace up to 750,000 people. This highlights the importance of preparedness and the development of evacuation plans to mitigate the risks associated with such a natural disaster.

In conclusion, while Mount Fuji is indeed an active volcano with a history of eruptions, predicting when it might erupt next is fraught with uncertainty. The scientific community continues to monitor its activity closely, using the best available technology and methodologies to understand the signs of unrest and to prepare for any potential future eruptions.

Volcano experts point out that the last time Mount Fuji erupted was in 1707, just 49 days after the massive 8.7 magnitude Hoei earthquake. ... In tandem with that report, a government study has warned that as many as 750,000 people may be forced to flee their homes if Mount Fuji does erupt on the same scale as in 1707.
