A volcanic island 600 kilometres west of Mexico’s coast, Socorro Island remains geologically active and stands as the largest of the Revillagigedo Archipelago’s four islands.
At a glance
Socorro Island measures 16.5 by 11.5 kilometres, encompassing 132 square kilometres of volcanic terrain. Its remote location in the eastern Pacific Ocean—370 miles from mainland Mexico—has shaped both its ecology and human presence. The island’s volcanic origins continue to define its character.
History
Part of the Revillagigedo Islands, a Mexican possession, Socorro Island has remained a remote outpost in the Pacific. The island’s most recent volcanic eruption occurred in 1993, a reminder of its dynamic geology.
What you see
The island’s landscape reflects its volcanic foundation. Dramatic peaks and volcanic formations characterise the terrain, shaped by millions of years of tectonic activity in this geologically active region.
Cultural significance
Socorro Island holds importance for marine conservation and geological study. Its isolation has created unique ecosystems that attract scientific researchers and ocean explorers interested in volcanic and marine environments.
