A lahar is a mudflow that results from water mixing with volcanic ash. They can be hot or cold.
A pyroclastic flow is a flow of superheatd ash, rock and gas that moves down the side of a volcano and is much hotter than a lahar. This material is ejected directly from a volcano.

What is the difference between a pyroclastic flow and a pyroclastic surge?
A pyrcoclastic flow is is much denser than a pyroclastic surge, as a large portion of it is composed of ash and rock. A pyrcolastic surge is composed more of gas.
Why do pyroclastic flows have a higher percentage of deaths than lahars?
A lahar is a mudflow that behaves in a similar manner to a flood, though it is much denser. You can be swept away by a lahar, but you can still escape.A pyroclastic flow moves much faster than a lahar, so it is much harder to escape. If you care caught in one you will likely be subjected to temperatures of hundreds of degrees. Such conditions are not survivable.
