The frequent historic eruptions occurred all from the Me-Akan group, east of Lake Akan. Me-Akan volcano (雌阿寒岳 Meakan-dake) consists of 9 overlapping cones. Its summit has 3 craters. Me-Akan has had at least 17 small phreatic eruptions since the beginning of the 19th century and from geologic studies it is known that there were at least 4 major magmatic eruptions with pyroclastic flows have occurred in prehistoric time during the past 10,000 years. Lake Akan is part of the Akan National Park. It is known for a rare green algae (marimo) which can grow to about the size of a soccer ball. The only town around the lake is the resort of Akankohan known for its hot springs and the "bokke", bubbling mud pools found at the lakeshore. Background:The Akan caldera is located immediately SW of Kutcharo caldera and has an elonogated, irregular shape due to several caldera-forming explosive eruptions between the early and mid Pleistocene.Growth of 3 post-caldera stratovolcanoes, 3 at the SW end of the caldera and the other at the NE side, has reduced the size of the caldera lake. The conical O-Akan volcano was frequently active during the Holocene. The 1-km-wide Nakamachineshiri crater of Me-Akan volcano was formed during a major pumice-and-scoria eruption about 13,500 years ago. Akan Photos:
2008 eruption
Tremor was recorded on 17 November 2008. A small ash eruption occurred on 18 November, and was later detected by a fresh deposit of ash on snow in up to 400 m distance from the Ponmachineshiri crater. Another ash eruption occurred on 28 November, producing a small ash plume reaching 2 km altitude. (Source: Smithsonian / GVP monthly reports) 2006 eruption
A small eruption occurred from a vent on the NE flank of Meakan on 21 March 2006. Ashfall was observed 10 km SE of the volcano. 1998 eruption
