Wolf Volcano on the northern end of Isabela Island began erupting Monday, May 25th, for the first time in 33 years. Wolf is the tallest of Isabela's six major volcanoes, and the highest peak in the Galápagos.
Lava is currently flowing in a south-westerly direction, and does not currently represent a threat to visitor sites. Scientists believe neither the saddleback subspecies of Galapagos Tortoise chelonoidis negra becki nor the Pink Land Iguana conolophus marthae are currently threatened, as their range is limited to the north-western slopes of the volcano.

Our friends at Galapagos Conservancy have provided a map detailing the endemic species habitat regions in relation to the lava flow. We're happy to report that neither the pink land iguanas (pink boundary) nor the land tortoises (white boundary) are threatened by the ongoing lava flow from the Wolf Volcano eruption.
