BeschreibungThe volcano is located at the NW end of the Guaymas lineament. Initial basaltic-andesite and andesitic submarine surtseyan eruptions produced palagonite tuffs and were followed by the effusion of subaerial dacitic lava flows and the formation of dacitic tuff rings.
The latest eruptions formed 2 rhyolitic obsidian domes, the younger inside a tuff cone at the center of the island and at the older located at the NW tip of the island.
