Cerro Quemado is the youngest lava dome complex of Volcán de Almolonga and is seen here across the Llano del Pinal plain. Collapse of the NE flank about 1,150 years ago produced a debris avalanche deposit that forms the undulating topography in the foreground. An associated lateral blast also occurred across the Llano del Pinal. The eruption concluded with the emplacement of a small lava dome inside the avalanche scarp.
