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 landslides during the January 2001 earthquake. The capital city of San Salvador lies beyond the lake, in front of San Salvador volcano (upper right). The Santa Ana volcanic complex lies beyond San Salvador volcano in the background to the far right.
