Segula Volcano

關於
Segula Volcano lies 1,228 miles (1,976 km) westward of Anchorage on the Segula Island in the Aleutian Islands of Alaska. An inactive stratovolcano, it has not produced any historical eruptions, while barely eroded deposits on the flanks suggest that activity took place at the volcano as late as a couple of hundred years ago.
Built on top of a shallow platform, the volcano grew steadily from eruptions, and is composed of strata of flow deposits and pyroclastic material.
