Pyroclastic flows transfer more similar to a dense, small-viscosity fuel pouring down a slope as well as go upslope if they may have ample momentum; their downslope velocities often exceed a hundred km (sixty miles) per hour.
Lahars flow like liquids, but simply because they incorporate suspended product, they sometimes have a consistency much like damp concrete. They flow downhill and can abide by depressions and valleys, but they are able to spread out when they get to a flat space.
Lahars usually are not as rapidly or warm as other volcanic dangers, but they are really harmful. They're going to both bulldoze or bury anything within their route, from time to time in deposits dozens of toes thick. Whatever simply cannot get from a lahar's path will both be swept away or buried.
