Collapse of México's Colima volcanic complex during the late Pleistocene produced a major debris avalanche and debris flow that traveled 120 km to the Pacific Ocean. The quarried hummock in the foreground and the two brown hills in the middle distance are composed of material transported more than 100 km from Colima volcano (seen in the far distance above the left-hand hummock) and incorporated from valley floors during transport.
