Volcán Wolf

Wolf

Shield volcano · Ecuador · 1710m

Wolf, the highest volcano of the Galápagos Islands, is located near the equator at the N end of the archipelago's largest island, Isabela. The summit caldera is 5.5 x 7 km and 600 m deep, with recent lava flows covering the broad caldera floor. Prominent unvegetated lava flows are visible on the flanks to the sea. Wolf's 1797 eruption was the first documented in the Galápagos Islands.

Geological summary

Volcán Wolf, the highest volcano of the Galápagos Islands, straddles the equator at the north end of the archipelago's largest island, Isabela. The edifice has steeper slopes than most other Isabela volcanoes, reaching angles up to 35°. The summit caldera is 6 x 7 km across and 700 m deep. A prominent bench on the west side of the caldera rises 450 m above the caldera floor, much of which is covered by a lava flow erupted in 1982. Radial fissures concentrated along diffuse rift zones extend down the N, NW, and SE flanks, and submarine vents lie beyond the N and NW fissures. Similar unvegetated flows originating from a circumferential chain of spatter and scoria cones on the eastern caldera rim drape the forested flanks to the sea. The proportion of aa lava flows exceeds that of other Galápagos volcanoes. An eruption in in 1797 was the first observed and documented in the Galápagos Islands.
