#Lahars are floods of water, rock, ash and debris that can happen during and after volcanic eruptions. Lahars can be immensely powerful, destroying bridges and buildings, and traveling great distances to bury vast areas in mud. If you live in a valley or on a flood plain near a volcano, you should be aware of the potential for lahars. If you hear a rumbling from upriver or notice the water levels rising, move to high ground immediately. This video is part of the #VolFilm volcano hazards series.

One of the most tragic volcanic events of the 20th century occurred in Colombia, in 1985, when an eruption of Nevado del Ruiz produced lahars that swept down river valleys and destroyed communities in its path. Mount Rainier and other volcanoes of the Pacific Northwest’s Cascade Range are similar to Nevado del Ruiz in many respects—massive amounts of snow and ice, a long history of lahars, and narrow valleys leading to populated areas. Could what happened at Nevado del Ruiz happen in the Pacific

One of the most tragic volcanic events of the 20th century occurred in Colombia, in 1985, when an eruption of Nevado del Ruiz produced lahars that swept down river valleys and destroyed communities in its path. With little warning, the volcano began erupting on the afternoon of November 13, 1985. Ash and muddy rain began to fall. Communities were alerted but no formal decision was made to evacuate. Later that evening, a stronger eruption produced pyroclastic flows and surges that mixed with snow
