Ekarma Volcan
Ekarma stratovolcano forms a small 5 x 7.5 km island 8.5 km north of Shiashkotan Island in the northern Kurile Islands, Russia.
The volcano belongs to an E-W-trending volcanic chain extending westward from the central part of the main Kuril Island arc. It contains two overlapping basaltic-andesite to andesitic volcanoes, with the western one showing historical activity. Lava flows have flown 3 km in all directions from the summit of the younger cone to the sea, forming a sinuous shoreline.
The island summit is formed by a lava dome which formed in the first historic eruption of Ekarma between 1767-69.
