Introduction

The caldera had been formed about 7500 years ago during a massive eruption, one of the largest known from the Kurile Islands. Volcanic activitiy after the caldera formation has built a large new summit cone, the andesitic Krenitzyn Peak, which rises high above the caldera rims.
Krenitzyn has grown about 1000 meters in 7500 years and now forms a 4 km wide island and fills the NW part of the caldera.
The summit contains a 350-m-wide and 100-m-deep crater, and there is a large lateral crater on the upper NE side.
