Koryaksky is the part of the NW-trending Avachinskaya volcano group near Kamchatka's largest city, Petropavlovsk. This view from below the saddle between Avachinsky and Koryaksky volcanoes shows the eroded SE flank. The youngest lava flows are on the upper W flank and below SE-flank scoria cones. Moderate explosive eruptions have occurred since the first historical eruption in 1895.
