Photo Gallery

The vegetated volcano located on the shore of the Sea of Okhotsk (left) in the left-center portion of this Landsat image of central Urup Island is Tri Sestry volcano ("Three Sisters"). The flanks of this eroded andesitic stratovolcano are cut by deep ravines. A summit lava dome was active during either the late Pleistocene or early Holocene, and hot springs along the coast mark the latest activity. The crater lake of Rudakov volcano is visible at the lower left.
