Seismic detection and tracking of avalanches and slush flows on Mt. Fuji, Japan
Description
<jats:p>Abstract. Avalanches are often released at the dormant stratovolcano Mt. Fuji, which is the highest mountain of Japan (3776 m a.s.l.). These avalanches exhibit different flow types, from typical dry-snow avalanches in winter to slush flows triggered by heavy rainfall in late winter to early spring. Avalanches from different flanks represent a major natural hazard as they can reach large dimensions with run-out distances up to four kilometres, regularly destroy parts of the forest and sometimes damage infrastructure. For monitoring the volcanic activity of Mt. Fuji, a permanent and dense seismic network is installed around the volcano. The small distance between the seismic sensors and the volcano flank ( </jats:p>
