The glacier on Nevado del Ruiz is seen here above the Azufrado valley on the NE flank. Debris avalanche deposits from an eruption roughly 3,100 years ago, and from the 1595 eruption, appear in the foreground. The major eruption about 3,100 years ago produced a large ashfall deposit, the debris avalanche, and associated lahars and pyroclastic surges. The 1595 eruption, the largest from Ruiz in historical time, was similar. Lahars in 1595 caused over 600 fatalities.
