Beware of the Tokachidake eruption

A field survey conducted from the 12th to the 13th showed that the geothermal area within the 62-2 crater had expanded compared to last year, and that the crater temperature had clearly increased (approximately 400 degrees this time, approximately 200 degrees in June 2019). confirmed. From the 7th to the dawn of the 15th, we occasionally observed a phenomenon in which the area around the 62-2 crater appeared bright. This phenomenon is so faint that it can only be confirmed by a highly sensitive surveillance camera, and is thought to be caused by high-temperature gas emissions and combustion of sulfur. 　In relation to this phenomenon, no increase in volcanic earthquakes or volcanic tremors was observed, and there were no particular changes in crustal movement and infrasonic data. Also, there is no change in the volcanic plume from other craters. At the 62-2 crater, from around 1998 to around 2000
