Resumen geológico
The small 5 x 7.5 km island of Ekarma lies 8.5 km N of Shiashkotan Island along an E-W-trending volcanic chain extending westward from the central part of the main Kuril Island arc. It is composed of two overlapping basaltic andesite to andesitic volcanoes, the western of which has been historically active. Lava flows radiate 3 km in all directions from the summit of the younger cone to the sea, forming a lobate shoreline. A lava dome that was emplaced during the first historical eruption, in 1776-79, forms the peaked summit of the island.
