According to a report by Global Network, citing the local ** South Nippon Broadcasting Corporation (MBC) in Kagoshima Prefecture, Japan, just after 3 pm local time (2 pm Beijing time) on January 1, the Mount Ontake volcano on Suwa no Se Island in Kagoshima Prefecture erupted. The plume of smoke erupting from the crater is 1,600 meters high. A small amount of ash is expected to fall on the island by 9 p.m., the report said.
The area around the crater of Suwa Se Island is still under the Eruption Alert Level 2 limit, and the meteorological department has urged local residents to be alert to large lava blocks near the crater, MBC said.
On the same day, according to CCTV News, citing the Indonesian Volcano and Geological Hazard Research Institute, at 5:23 local time on January 1 and 6:23 Beijing time, Indonesia's Irilevo Toloko volcano erupted, with an ash column 300 meters high and an eruption duration of 53 seconds.
Soon after, at 7:15 Beijing time, Indonesia's Dukono volcano also erupted, lasting 49 seconds, and the ash column was 2,000 meters high.
On January 1, local time, the Indonesian Volcano and Geological Hazard Research Institute raised the eruption warning level of Iri Levo Toloko volcano, from level 2 to **. It is understood that the volcanic eruption warning level in Indonesia is divided into 4 levels, with level 4 being the highest. Grade 3 means that there is an increased likelihood of a volcanic eruption, but it does not threaten residential areas. People should be vigilant and refrain from activities in areas near the summit.
Indonesia is one of the most volcanic countries in the world, with more than 120 active volcanoes in the territory. Among them, Mount Malapi in Indonesia erupted several times last month, killing 24 people.
According to the Indonesian Meteorology, Climatology and Geophysics Agency, at 14:52 local time on January 1, 5Magnitude 5**, hypocenter depth 46 km.
Regarding whether there is a connection between the recent frequent ** and volcanic activity, Gao Mengtan, a distinguished expert from the Institute of Geophysics of the China ** Bureau, said in an interview with CCTV News that Southeast Asia is located in the area where the Pacific Rim ** belt and the Eurasian ** belt meet, and this region is also the area with the strongest volcanic activity on the earth. To the west of Indonesia is the Indian plate, the Indo-Australian plate, to the east, and to the east is the Eurasian plate, as well as the Pacific plate. These three plates are very interacting areas, and the mutual squeezing of the plates will cause the activity of crustal faults, triggering **, and volcanoes will form upstream of the deep thermal material.
Gao Mengtan pointed out that overall, the level of activity above level 7 this year is roughly the same as the average level in the past 20 years. At present, the tectonic movement in Southeast Asia is relatively strong, and the volcanic activity and the hazards brought by it should be of great concern in the future.
