Ilopango caldera is seen in this aerial view from the SW with San Vicente stratovolcano to the right. The latest collapse of the 13 x 17 km caldera occurred after a powerful eruption during 536-550 CE that produced widespread pyroclastic flows and devastated early Mayan cities. The caldera now contains a lake with lava domes forming small islands near the shore and near its center. Copyrighted photo by Stephen O'Meara.
