Prediction of eruption time of Mount Fuji volcano

The eruption time of Mount Fuji volcano is uncertain and unpredictable.

170710128 October 13: 45, a major earthquake occurred in the southern waters of Mu Yi Peninsula, south of Honshu Island. It is estimated that the magnitude of the earthquake is between 8.7 and 9.3, and the diameter of the range where the earthquake intensity reaches 7 degrees is 790 kilometers. The earthquake and tsunami even spread to China and Shanghai.

1707 12 16 when the mount fuji volcano erupted in Japan, the height of volcanic ash eruption reached 20 kilometers, even in edo (now Tokyo), which is 0/00 kilometers away from/kloc.

The volcanic eruption lasted about 2 weeks, and the amount of volcanic eruption was estimated to be 700 million cubic meters. This volcanic eruption is also one of the three major eruptions of Mount Fuji in Japan in the past 2000 years, which formed today's Baoyong Mountain.

Changes of observation at the top of Mount Fuji and the present situation of weather stations

1, set up a central meteorological observatory at the top of Mount Fuji, and start weather observation all year round. In April, 1965, meteorological telemeter, 1974, update the observation report of transmission lines, 1978, update the Fuji radar.

1984 Digitization of Mount Fuji Radar 1985 Meteorological telemetering device is updated to ground meteorological observation device of Mount Fuji Meteorological Observatory, 1987 Mount Fuji Meteorological Observatory is equipped with volcano observation seismograph. The operation of Mount Fuji radar ended at 1999, and Nagano and Shizuoka radars started to operate at the same time. A seismometer was installed at the eighth station in 2002.

2. Mount Fuji Meteorological Station (Mount Fuji) is equipped with four permanent staff (replaced every three weeks), whose work includes ground meteorological observation, maintenance and inspection of observation equipment, and observation items: wind direction, wind speed, temperature, air pressure, solar radiation, weather, volcano observation and other meteorological observations, and 2 seismometers (of which 1 is the eighth).
