The resort town of Panajachel occupies a delta of the river of the same name that flows into Lake Atitlán, within the Atitlan caldera. The northern caldera wall rises about 1 km above the lake surface. The level of the lake has fluctuated more than 10 m over periods of several decades, and titles exist to land now submerged hundreds of meters from the current shoreline. High heat flow is present in the lake.
