- ALASKA VOLCANO OBSERVATORY GLOSSARY
A flowage of water-saturated earth material possessing a high degree of fluidity during movement. A less-saturated flowing mass is often called a debris flow. A mudflow originating on the flank of a volcano is properly called a lahar.\GLOSSARY OF VOLCANIC TERMSA flowing mixture composed of water and mud (clay- and silt-sized sediments). The term should be used exclusively for mud-dominated mass flows, and should not be used as a substitute for the term "lahar"(Rodolfo, 2000, p. 973-974). Mudflows are common in both volcanic and non-volcanic environments.
