The Sierra Negra volcano on Isabela Island in the Galapagos erupted on Tuesday, causing evacuations and triggering an orange alert. Two strong 5.3-magnitude earthquakes shook the Sierra Negra volcano, triggering a new eruptive period for the volcano. Strong lava fountains and multiple flows of lava were seen on Tuesday, June 26.
It has been 13 years since Sierra Negra last erupted and 10 days since La Cumbre volcano erupted on neighboring island Fernandina. Fernandina Island is uninhabited but endangered nearby wildlife with a lava flow that entered the ocean. Isabela Island has a population of 1,748 and is the largest island in the Galapagos with volcano Sierra Negra at the southeastern end of the island. READ MORE
