summit elevation 1100 m
Isla Guadalupe is located in the Pacific Ocean, 250 km off the coast of Baja California. The island is built on the axis of a fossil spreading center.
The island consists of two overlapping shield volcanoes. The southern volcano is the older of the two. Caldera collapse has occurred at both volcanoes, which are covered by lava flows. A series of north-trending fissures is marked by cinder cones.
The northern volcano is the most exposed. The oldest rocks were erupted about 7 million years ago.
No recent eruptions.
