The scientists have said that the pressure in the magma chamber of Mount Fuji is now higher than what it was the last time the volcano had erupted. The volcano had erupted more than 300 years ago.
There have been changes in the pressure which was triggered by the 9.0 magnitude undersea earthquake which left the chamber under 16 times the minimum pressure at which the eruption can occur. The Tectonic movements have been studied by the Researchers at the National Research Institute of Earth Science and Disaster Prevention.
The tectonic movements were triggered due to the tsunami triggering earthquake on March 11, 2011 and an earthquake of 6.4 magnitude which had ricked central Japan four days later. The researchers estimated 1.6 megapascals of pressure, equivalent to atmospheric pressure of some 15.8 kilograms per square centimetre, it was being exerted on the magma chamber.
Eisuke ujita, a senior researcher said that the volcanic eruptions can be triggered by as little as 0.1 mega pascals of pressure and the reading of 1.6 mega pascals is not a small figure. Mount Fuji is considered as one of Japan’s national symbols and had last erupted in 1707 after an earthquake had struck and boosted the pressure on its magma chamber.
