Photo Gallery

This dramatic Space Shuttle photo from a 1988 mission shows five major calderas of the Galápagos Islands. Caldera diameters capping these basasltic shield volcanoes range up to 8 km. At the lower left is Fernandina volcano. At the lower right is mostly vegetated Alcedo volcano on Isabela Island. Above and to the left is Darwin volcano, with the two prominent breached tuff cones, Tagus and Beagle, on its SW flank. Volcán Wolf is at the top of the photo, and Volcán Ecuador with its breached caldera forms the NW tip of Isabela Island.

Volcán Ecuador (left center) forms the tip of a peninsula straddling the equator at the NW end of Isabela Island. The western side of the volcano, the smallest of the six large shield volcanoes on Isabela, is breached nearly to sea level. A line of fissure-fed vents on the outer eastern flank can be seen connecting Volcán Ecuador with Volcán Wolf (upper right). Despite the absence of historical eruptions from Volcán Ecuador, the youthful morphology of its most recent lava flows resembles those of very recent flows on other Isabela Island volcanoes.

Volcán Ecuador, which straddles the equator at the NW end of Isabela Island, rises beyond a lava flow near Beagle tuff cone on the flanks of Darwin volcano. Ecuador is the smallest of the six large shield volcanoes on Isabela and is broadly breached to the coast on the side opposite this view. No historical eruptions are known; however, the youthful morphology of its most recent lava flows resembles those of very recent flows on other Isabela Island volcanoes. A line of NE-trending fissure-fed vents (right horizon) extends to the SE.

An aerial view from the NE shows Volcán Ecuador with its large caldera breached to the SW. Erosion has extensively modified the lower outer flanks of the volcano. East flank fissures at the lower left feed fresh lava flows, and large pit craters dot the upper eastern flank of the volcano. A large pyroclastic cone constructed on the floor of the caldera can be seen near the coast at the upper right, and fresh lava flows blanket the caldera floor.

An aerial view of Volcán Ecuador from the south shows the large horseshoe-shaped caldera breached to the west that was formed when the volcano collapsed, producing a large submarine debris avalanche. The volcano straddles the equator at the NW end of Isabela Island. Two large pyroclastic cones were constructed along the coast, and smaller cones are found on the caldera floor. Extensive dark-colored lava flows (right) originate from a NE-trending line of fissures that extends from the outer eastern flanks of the main edifice.

The western side of Volcán Ecuador has formed through caldera collapse and subsequent flank collapse, producing the caldera that opens towards the ocean in this March 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 13 km across). Within the caldera is the Cerro Grande tuff cone along the coast, a slump block along the SE caldera wall, and lava flows, as well as smaller vents. The East Rift is to the right in this image, towards Volcán Wolf out of view.
