A lava flow field is at the base of Izalco composed of flows that mostly erupted from flank vents. They were deflected by the flank of Santa Ana and extend as far as about 7 km from the Izalco summit. The vegetated Cerro Verde scoria cone is to the right and is part of a trend of cones and vents that erupted SE of Santa Ana.
