One of the lahars virtually erased Armero; three-quarters of its 28,700 inhabitants were killed. The first lahar was 30 meters (100 ft) deep, moved at 12 meters per second (39 ft/s), and lasted ten to twenty minutes. Traveling at about 6 meters (20 ft) per second, the second lahar lasted for thirty minutes and was followed by smaller pulses.

Laharz_py is a statistically based computer program capable of generating debris-flow and lahar hazard maps very rapidly, even in the absence of site-specific information other than topography. The software calculates a hazard zone on and around a volcano and estimates hazard zones downstream far from the volcano as areas of potential inundation.
