Wolf Volcano Eruption. Galapagos Islands. 2015.

Shield volcano 1710 m.
Galápagos Islands, Ecuador, 0.02°N / -91.35°W

Wolf volcano eruptions: 2015, 1982, 1797

A 6 x 7 km caldera, at 700 m one of the deepest of the Galápagos Islands, is located at the volcano’s summit. A prominent bench on the west side of the caldera rises 450 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 north, NW, and SE flanks, and submarine vents lie beyond the north 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 of the volcano to the sea. The proportion of aa lava flows at Volcán Wolf exceeds that of other Galápagos volcanoes. Wolf’s 1797 eruption was the first documented historical eruption in the Galápagos Islands.
