The 80-m-high headwall scarp of the 5 January 1991 landslide at the Almolonga volcano Zunil geothermal field exposes the regional Zunil fault zone. The avalanche deposit extends about 800 m from the source and damaged the highway between Quetzaltenango and the town of Retalhuleu on the Pacific coastal plain. The avalanche destroyed a church and more than a half-dozen houses, killing 23 people. The elevation difference from the head of the scarp to the distal end of the deposit was 250 m.
