Tri Sestry volcano has an eroded edifice consisting of the Tri Sestry cone with a lava dome at the summit and a 1-km-diameter crater on the NW slope, along with another edifice. The complex is seen here along the coastline of Urup Island, in this September 2019 Planet Labs satellite image mosaic (N is at the top), which is approximately 20 km across.
