Alamagan

Alamagan is an elliptical volcanic island in the Northern Mariana chain, about 30 kilometres north of Guguan and 250 kilometres north of Saipan. The island is the summit of a stratovolcano rising more than 4,000 metres from the Pacific floor, with a summit caldera, fumaroles, steep eastern cliffs and deeply eroded western canyons. Coconut palms grow on gentler slopes, and rare plants survive in isolated habitats.

Chamorro communities settled Alamagan before European arrival, leaving latte stone columns and pottery. Villages used the island’s forest, gardens and fishing grounds while maintaining canoe links with neighboring islands. The island appears in early Spanish accounts: Diego Luis de San Vitores recorded it in 1669 as Concepción. Its inhabitants were forcibly removed to Saipan in 1695 and to Guam three years later, ending the old settlement.

The island’s steep coast and volcanic terrain made access difficult even before that depopulation. Fresh water was limited, but forest and reefs supplied food and materials. Alamagan’s history therefore joins a living Chamorro settlement with a remote volcanic landscape whose isolation shaped both survival and vulnerability.
