A pyroclatic flow is a superheated flow of hot air, debris, ash. boulders and toxic gases. The Pyroclastis flow comes pouring down the volcanoe at 140-150 MPH
the temperature can be around 1000 degrees Celsius.
Best hope you're not around when one of these go off. Also never get by the lava after it has been erupted!!!!!!!

lava and rock fragments ejected in a volcanic eruption
Pyroclastic Materials. Any composition of lava can produce pyroclastic materials. Pyroclastic fragments are ejected from the volcano as solid fragments, often solidifying as they leave the volcanic vent, or fly through the air. Tephra comes in all sizes.
Volcanic airborne debris is classified as either solid (tephra, aka pyroclasts, including "volcanic bombs") or particulate (ash). Lava chunks ejected into the air around a vent is called "spatter."*When solids condense from gaseous pyroclastic flows, the rock material is called ignimbrite.
The cinder cone volcano is made entirely of pyroclastic.
Pyroclasts are single fragments that are produced following a volcanic eruptions where there expanding gases rapidly erupt resulting in either the fragmentation or obliteration of rock and magma. Fine-grained pyroclastic material is generally made from ash cause by extremely high fragmentation of rock or magma.
Blocks is the name used for the biggest pieces of tephra. Tephra is produced by a volcanic eruption.
Tephra flow is fragments of volcanic rock and lava. Pyroclastic flow is fast moving current of hot gas and rock.
Tephra, or pyroclastic materials deposited by falling through the air.

A. Pyroclastic Flow and D. Tephra. Apex
why is tephra dangerous: Tephra is usually dangerous because it can come in small sizes or bigger sizes it is made up of rock and smoke
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)
Tephra is basically ash, rock, cinders, and solidified lava spurted from a volcano.
