Following the 2011 Tōhoku earthquake , there was speculation in the media that the shock may induce volcanic unrest at Mount Fuji . In September 2012 , mathematical models created by the National Research Institute for Earth Science and Disaster Prevention ( NRIESDP ) suggested that the pressure in Mount Fuji 's magma chamber could be 1.6 megapascals higher than it was before its last eruption in 1707 . This was interpreted by some media outlets to mean that an eruption of Mount Fuji could be imminent . However , since there is no known method of directly measuring the pressure of a volcano 's magma chamber , indirect calculations of the type used by NRIESDP are speculative and unverifiable . Other indicators suggestive of heightened eruptive danger , such as active fumaroles and recently discovered faults , are typical occurrences at this type of volcano
