Active volcanoes are volcanoes that are currently erupting or expected to erupt very soon. The definition of active volcanoes varies in different countries. The most popular classification is to categorise those volcanoes that have erupted since the Holocene (11,700 years ago) as active volcanoes. Some countries, such as Japan, classify volcanoes that have erupted in the past 2,000 years as active volcanoes. There are approximately 1,343 active volcanoes on Earth, including Laohei Mountain and Huoshao Mountain in Wudalianchi, Tengchong Volcano in Yunnan Province, Tianchi of Changbai Mountain and Ma’anling in Haikou (Fig. 5).
