According to the research team of Taiwan Province Academia Sinica who has been observing Datun Mountain for a long time, Datun Mountain in Taiwan Province Province has been active frequently in the past year, which proves that Datun Mountain is an active volcano and may erupt in the next 6,543,800 years. Experts said that although there is magma chamber under Datun Mountain, the possibility of eruption is not ruled out, but it will not happen in a short time. In addition, the surrounding observation system is also perfect. In addition to personnel stationed every day, there are 40 earthquake observation stations and 8 GPS systems, 10 to 20 volcanic gas center points, which can monitor and master information at all times, so people don't have to panic excessively.

Volcanic ash refers to gravel and mineral particles with a diameter less than 2 mm ejected by a volcano. In the explosive volcanic movement, solid stones and molten mud are decomposed into fine particles to form volcanic ash.
