The pressure in Mount Fuji's magma chamber is now higher than it was in 1707, the last time the nearly 4,000-metre-high Japanese volcano erupted, causing volcanologists to speculate that a disaster is imminent.
The new readings, taken by the National Research Institute for Earth Science and Disaster Prevention, reveal that the pressure is at 1.6 megapascals, nearly 16 times the 0.1 megapascals it takes to trigger an eruption.

Last week it was California going into the ocean, so this is an improvement!
Lots of people addicted to fear on this site. Just telling you in case you want to work on it.

They need to like drill holes by volcanoes to make like low pressure points to soften or eliminate eruptions.
An active stratovolcano that last erupted in 1707–08, Mount Fuji lies about 100 kilometres (62 mi) south-west of Tokyo, and can be seen from there on a clear day.
The volcano is currently classified as active with a low risk of eruption. The last recorded eruption was the Hōei eruption which started on December 16, 1707 (Hōei 4, 23rd day of the 11th month) and ended about January 1, 1708 (Hōei 4, 9th day of the 12th month) during the Edo period. The eruption formed a new crater and a second peak (named Hōei-zan after the Hoei era) halfway down its side. Fuji spewed cinders and ash which fell like rain in Izu, Kai, Sagami, and Musashi. Since then, there have been no signs of an eruption. In the evening of March 15, 2011, there was a magnitude 6.2 earthquake at shallow depth a few kilometres from Mount Fuji on its southern side. But according to the Japanese Meteorological Service there was no sign of any eruption. In September 2012, readings taken by the National Research Institute for Earth Science and Disaster Prevention suggest that the pressure in Mount Fuji's magma chamber is now higher at 1.6 megapascals than it was in 1707.
