An aerial view of the Río Las Majadas valley in Guatemala on the NNE side of Tacaná volcano shows thick deposits of lahars and debris avalanches filling the valley. These deposits provide a flat surface for agricultural use in deeply eroded terrain. The valley drains from its headwaters in Guatemala through México into the Pacific Ocean, and lahars during future eruptions could affect both countries.
