Mount Aso, Kyushu Island, Japan
Kyushu is the third-largest island of Japan and the most southwesterly of its four main islands. It has a population of 13,231,995 (2006) and covers 35,640 km².
Parts of Kyushu have a subtropical climate, particularly the Miyazaki and Kagoshima prefectures.
The island is mountainous, and Japan’s most active volcano, Mt Aso, at 1,591 m, is located towards its center. There are also many other signs of tectonic activity, including numerous areas of hot springs. The most famous of these are in Beppu, on the east shore, and around Mt. Aso.
Mount Aso is the largest active volcano in Japan, and is among the largest in the world. Its peak is 1592 m above sea level and is easily identifiable here by its orange-brown color around the grey caldera.
Mount Aso’s caldera is 25 km across north to south and 18 km across east to west. The caldera has a circumference of around 120 km (75 miles), although sources vary on the exact distance.
The central cone group of Aso consists of five peaks: Mounts Neko, Taka, Naka, Eboshi, and Kishima. The highest point is the summit of Mount Taka, at 1592 m above sea level. The crater of Mount Naka, contains an active volcano which continuously emits smoke and has occasional eruptions.
