Ksudach

Ksudach (also known as Vonyuchy Khrebet Volcano) is a stratovolcano in southern Kamchatka, Russia. The last eruption of Ksudach was in March 1907, on or around 28 March, which was one of the largest ever recorded in Kamchatka with a Volcanic Explosivity Index of 5. The summit area comprises overlapping calderas. Two lakes, Bolshoe and Kraternoe, are located within calderas at the summit of Ksudach. These lakes, along with hot springs and the surrounding wilderness, make the Ksudach Volcano region a popular trekking destination. In the event of renewed volcanic activity, its remote location minimizes its potential hazard to humans.
