[SGD01-02] Installation of the First Gravity Station in the Mount Fuji Research Institute, and the Phase-Free gravity measurement
Keywords:Gravity, Mount Fuji, Volcano Monitoring, Verification of Gravimeter, Phase-Free
There is another interesting point for the gravity observation in Mount Fuji. The gravity difference between MFRI and the fifth station of the Yoshida trail is about 320 mGal, and the travel time between two points is about 30 minutes. It means that this is a good observation line for the verification of the gravimeters. Now we suggest the "phase-free" gravity measurement (https://phasefree.org/). The idea of "phase-free" is to eliminate the social phases (time, state) of normal times and disasters, so that goods or services normally used can be appropriately used at the time of disaster. If we continuously use the gravity observation line for the verification by various gravimeters in the normal time, that will be the important data for the volcano monitoring when the Mount Fuji is starting to prepare the eruption.
