Because Lava is very slow so you can run from it and it cools and hardens into rock when it sets, however pyroclastic flows are round 140mph so you cant run from them.
A vulcanologist is most likely to study the cooling of lava after a volcanic eruption

Eruption products from Mount Kilauea include lava flows, volcanic gases (such as sulfur dioxide), ash, and volcanic tephra (fragments of volcanic rock). Lava flows are the most common product and can vary in composition from low-viscosity basaltic lava to more viscous and explosive lava compositions.
Shield volcanoes have effusive eruptions. Effusive eruptions are a volcanic phenomenon; in some ways the opposite of explosive eruptions. An effusive eruption is characterized by an outpouring of low viscosity lava which has a fairly low volatile content. Usually, shield volcanoes have effusive eruptions.

The most recent eruption of Kilauea began on December 20, 2020 and lasted until May 2021. This eruption resulted in lava flows, volcanic gas emissions, and other volcanic activity in the area.
The most common type of volcanic eruption occurs when magma (the term for lava when it is below the Earth's surface) is released from a volcanic vent. Eruptions can be effusive, where lava flows like a thick, sticky liquid, or explosive, where fragmented lava explodes out of a vent.
Kohala's most dangerous eruption occurred around 120,000 years ago. This eruption produced large lava flows that reached the ocean and caused significant destruction in the surrounding areas.
Small, slow eruptions are the most common. In Hawaii, for instance, many volcanoes are constantly erupting, although this "eruption" is really just a slow flow of lava.
Both the Pelean and Plinian eruptions are violent, and the Plinian (such as Vesuvius) are the most spectacular type. More specifically, there is a designation "ultra-Plinian" to describe highly explosive eruptions such as Kratatoa. The type of eruption that is most violent is when lava, ash and other materials are hurled into the air.
A volcanologist or a geologist specializing in volcanoes would be most likely to study the cooling of lava after a volcanic eruption. They would investigate the physical and chemical properties of the cooling lava to understand its behavior and how it solidifies over time.
False. The greatest hazard comes from pyroclastic flows.
