Details for: Koryaksky
The large symmetrical Koryaksky stratovolcano is the most prominent landmark of the NW-trending Avachinskaya volcano group, which towers above Kamchatka's largest city, Petropavlovsk. This view from below the saddle between Avachinsky and Koryaksky volcanoes shows the erosionally produced ribbed surface of the SE flank of 3456-m-high Koryaksky. The youngest lava flows are found on the upper western flank and below SE-flank cinder cones. Only a few moderate explosive eruptions have occurred since the first historical eruption in 1895.
