Geography and Geology

Shinmoedake is a stratovolcano with a crater and a summit elevation of 1,796 meters above sea level. The volcano is part of the Kyushu volcanic arc, which is a zone of intense volcanic activity caused by the subduction of the Philippine Sea Plate under the Eurasian Plate. The geology of the area is characterized by andesite and dacite lava flows, pyroclastic flows, and volcanic ash deposits.

Eruptive History

The eruptive history of Shinmoedake dates back to the Pleistocene era. The volcano has experienced several phreatomagmatic and explosive eruptions, producing volcanic ash and pyroclastic flows that have affected the surrounding areas. One of the most significant eruptions occurred in the 17th century, which produced a large lahar that flowed into the Kobayashi area.

2011 Eruption

In 2011, Shinmoedake experienced a significant eruption that began on January 19, 2011. The eruption was characterized by explosive and effusive activity, producing volcanic ash and lava flows. The eruption forced the evacuation of nearby residents and disrupted air travel in the region. The Japan Meteorological Agency JMA closely monitored the volcano's activity and provided early warnings to the public.

Monitoring and Hazards

Shinmoedake is closely monitored by the Japan Meteorological Agency JMA, which tracks the volcano's seismic activity, ground deformation, and gas emissions. The volcano is considered active and poses a threat to nearby communities and air travel. The JMA and other scientific organizations, such as the University of Tokyo and the Japanese Society for the Promotion of Science, work together to monitor the volcano's activity and provide early warnings in case of an eruption.
