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 pyroclastic flows and lava flows?
Lava is molten rock at earth's surface. A pyroclastic flow is an avalanch-like flow of hot ash, rock, and gas that moves down a volcano's flanks at great speed.
What are 10 vocabulary words for the famous volcanic eruption of Kilauea?
Lava Ash Pyroclastic flow Volcanic plume Caldera Lahar Vent Tephra Fissure Geothermal activity
What is the difference between pyroclastic and a lahar?
Pyroclastic flows are fast-moving currents of hot gas and volcanic matter that flow down the slopes of a volcano during an explosive eruption, characterized by their high temperatures and speeds. In contrast, lahars are volcanic mudflows or debris flows that occur when volcanic materials mix with water, often from rain or melting snow, resulting in a flow of mud and rock down the slopes of the volcano. While both are hazardous volcanic phenomena, pyroclastic flows are primarily composed of volcanic gases and solid particles, whereas lahars primarily consist of water-saturated debris.
What is the term for lava flow that travels downhill at over 100mph?
Pyroclastic flow
What is the difference between a pyroclastic flow and a pyroclastic surge?
A pyroclastic flow is a dense, fast-moving avalanche of hot gas, ash, and rock fragments that travels down the slope of a volcano. A pyroclastic surge is a turbulent cloud of hot gases and ash that moves laterally across the ground at high speeds during a volcanic eruption. Pyroclastic flows are more dense and destructive, while pyroclastic surges are less dense and can cover larger areas.
Was eyjafjallajokull a lahar or a pyroclastic flow?
Neither. It is a volcano that famously erupted in 2010. The eruption produced pyroclastic flows.

Pyroclastic flow
What is more deadly lava or pyroclastic flow?
Pyroclastic flow.

What volcano produces a pyroclastic flow?
an explosive volcano will usually have a pyroclastic flow
What is the difference between a lahar and a mudflow?
A lahar is a type of mudflow specifically composed of volcanic debris and water, often triggered by volcanic eruptions or volcanic activity. A mudflow, on the other hand, is a rapid flow of water-saturated earth materials that can occur due to heavy rainfall, snowmelt, or other natural causes.
A mud flow on a volcano is called?
Lahar
Can you outrun a pyroclastic flow?
No. A pyroclastic flow can move at well over 100 mph.
How can pyroclastic flow be used in a sentence?
The pyroclastic flow from the volcano devastated the surrounding area, burying everything in its path under a blanket of ash and hot gases.
What damage doese volcanoe cause?
What usually causes the most damage is the pyroclastic debris and the ash. The ash isn't normal fire ash (tephra) more than 10 cm of volcanic ash can collapse a building. The next most devastating factor is the pyroclastic flow (lahar), gases through fumaroles and lastly the lava is least devastating. (Anyone can out run a lava flow... backwards)
