IEDA / DECADE Detail

Data from the Global Volcanism Program of the Smithsonian Institution

Details for: San Luis, Isla

Isla San Luis lies across a narrow channel from the NE coast of Baja California (visible in the background). The center of the small island is dominated by a dramatic dark-colored rhyolitic obsidian dome. An older dome, partially mantled by ash and pumice from the central dome, forms the northern part of the island (foreground). A dissected tuff ring, Plaza de Toros, occupies the SE end of the island. A sequence of rocks ranging from initial basaltic-andesite and andesitic palagonite tuffs to rhyolitic lava domes was erupted during a short time interval. Photo by Keith Sutter, 2000.
