What is wetter lahars or pyroclastic flows?

Lahars are wet. They are mudflows that result from volcanic ash mixing with water. Pyroclastic flows are superheated clouds of ash and gas that move down the slopes of a volcano. They are too hot to be wet.

What are Fast moving clouds of hot gas and ash that move down the side of a volcano?

That large, Heavy cloud is composed of fast-moving currents of hot gas and rock, which travel away from the volcano at speeds generally as great as 700 km/h (450 mi/h). The gas can reach temperatures of about 1,000 degree celcius(1,830 degrees fahrenheit). The flows normally hug the ground and travel downhill. most commonly known as a Pyroclastic flow. A Pyroclastic surge is a fluidized mass of turbulent gas and rock fragments which is ejected during some volcanic eruptions. It is similar to a pyroclastic flow but contains a much higher proportion of gas to rock, which makes it more turbulent and allows it to rise over ridges and hills rather than always travel downhill as pyroclastic flows do.
