Lahar at Merapi Volcano

A lahar is a mudflow composed mainly of volcanic debris and water. They are formed when rainwater washes away the volcanic ash on a volcano slope. Sometimes caused lahars when crater lakes leak. Lahars are among the biggest risks of a volcanic eruption. Huge Lahars are known from Mount St. Helens and Nevado del Ruiz where thousands of People were killed by Lahars.
I filmed this lahar at Mount Merapi volcano in the year of 2010.
