Volcán Ecuador is the only volcano on Isabela Island not known to have erupted in historical times. However, the geomorphology of its youngest lava flows is comparable to those of very recent lava flows from other volcanoes on Isabela Island. Like Volcán Wolf to the east, Volcán Ecuador straddles on the equator. It is also the only volcano on the island without its own native Gálapagos tortoise (Chelonoidis nigra) population.
