The Volcano Eruption Prediction Liaison Committee, which is made up of experts on Nakanoshima, an active volcano in the Tokara Islands of Kagoshima Prefecture, recommends that activities be monitored 24 hours a day, considering that activities may become active in the future. I wore it.
The Volcanic Eruption Prediction Liaison Committee has been studying active volcanoes that should be strengthened in addition to the "always-observed volcanoes" that the Meteorological Agency monitors 24 hours a day, and has been observing volcanic earthquakes and eruptions.
As a result, on Mt. Ontake on Nakanoshima in the Tokara Islands, seismic activity is active and several tens of tons of volcanic gas are released every day, and it is thought that there is high-temperature magma underground.
The Volcanic Eruption Prediction Liaison Committee held a regular meeting on the 5th, saying, "Nakanoshima has the potential for active volcanic activity in the future, and we should not overlook the increase in activity." We have put together a recommendation for monitoring.
In the future, the Japan Meteorological Agency will proceed with efforts to build a regular observation system, such as considering the introduction of observation equipment and eruption alert levels, in consultation with local governments and experts.
The Japan Meteorological Agency has 50 "always-observed volcanoes" nationwide, and with the addition of Nakanoshima, there will be three "Hakkoda Mountains" in Aomori Prefecture, "Towada" on the prefectural border between Aomori and Akita, and "Midagahara" in Toyama Prefecture in 2016. Since it was added.
According to the Japan Meteorological Agency, there was a mud eruption on Nakanoshima in 1914, and no eruption or noticeable volcanic activity has been observed since then.
According to the website of Toshima Village, Nakanoshima is the largest of the Tokara Islands and has a population of about 160, and Mitake, located in the northwest of the island, is 979 meters high.
