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.
