Explicación
## Step 1A pyroclastic flow is a high-density, ground-hugging avalanche of extremely hot volcanic ash, rock fragments, and gas that rushes down the sides of a volcano during an explosive eruption. This phenomenon is most likely to occur in a plinian eruption.## Step 2Plinian eruptions are characterized by their explosive nature and the ejection of large amounts of pumice and ash high into the atmosphere. This type of eruption is named after Pliny the Younger, who described the eruption of Mount Vesuvius in 79 AD.## Step 3The other options provided, Hawaiian, fissure, and strombolian eruptions, are different types of volcanic eruptions. However, they do not typically produce the explosive activity and high-viscosity lava that lead to pyroclastic flows.
