Neither. It is a volcano that famously erupted in 2010. The eruption produced pyroclastic flows.
Beware the pyroclastic flow!
A lahar is a mudflow that forms from water mixing with volcanic material, primarily ash. A nuee ardente, more commonly known as a pyroclastic flow, is a superheated, fast-moving body of ash, rock, and gas that moves down the sides of a volcano as a direct result of an explosive eruption.
Tephra flow is fragments of volcanic rock and lava. Pyroclastic flow is fast moving current of hot gas and rock.

The answer is LAHAR.
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.
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.
Pyroclastic flow.
Beware the pyroclastic flow!
Pyroclastic flow
A lahar is type of mudflow associated with violent eruptions. It is composed of a slurry of pyroclastic material, water and rocky debris.
an explosive volcano will usually have a pyroclastic flow
No. A pyroclastic flow can move at well over 100 mph.

Lahar
Pyroclastic flows occur during explosive eruptions of volcanoes.
