Japan earthquake has raised pressure below Mount Fuji, says new study

"We cannot establish a direct relation of cause and effect between quakes and volcanic eruptions, even if statistically the former lead to an increase in the latter," Brenguier says. "All we can say is that Mount Fuji is now in a state of pressure, which means it displays a high potential for eruption. The risk is clearly higher," said Florent Brenguier, a researcher at the Institute of Earth Sciences (IST) in Grenoble, France, and lead author of a study 'Mapping pressurized volcanic fluids from induced crustal seismic velocity drops' in an interview with The Guardian.
