The 8 x 11 km wide Ilopango caldera fills the center of the image in this view from the ESE. Fresh, light-colored exposures of the Tierra Blanca Joven formation in the foreground associated with the latest caldera-forming episode were in part created by landsliding during the January 2001 earthquake. The capital city of San Salvador lies beyond the lake, between it and San Salvador volcano (upper right). The Santa Ana volcanic complex lies beyond San Salvador volcano on the right horizon.
