es and is one of the most active in southern Kamchatka.
Gorely is a large, long-lived shield-type volcano that is currently in an eruptive phase. Prior eruptions occurred in 1980-81 and 1984–86.
Several complexes compose the overall volcanic structure:
- ancient Pra-Gorely volcano which measures 20–25 km in diameter;
- a 12 km diameter caldera;
- thick stratum of ignimbrites totaling a volume of 100 km³;
- post-caldera eruption cinder cones;
- modern edifice – “Young Gorely” composed of three large superimposed cones and 11 associated craters forming a NW-SE trending intra-caldera ridgeline;
- a complex of 40 modern subsidiary cones on the slopes of “Young Gorely”. In 2010, activity began to increase, suggesting the volcano was waking up. A new vent was discovered on the inner southeast wall of the crater
