Geography
The island consists of several overlapping stratovolcanoes, and it contains two calderas each with central volcanic cones. On March 6, 1977 USCGC Mellon WHEC 717 spotted a volcanic eruption just a few hours old on Seguam Island in the Aleutian chain. About 10 historical eruptions have been recorded since the late 18th century, the most recent in 1993. On recent activity has occurred at Pyre Peak, the cone within the western caldera and the highest point on the island, and has produced explosive eruptions and basalticlava flows.
