what is the most deadly phase of a volcanic eruption like the one at vesuvius (show link to this)

Since you have a test, I'm sure these answers are in your book.

I don't have a book I need your help

The most deadly phase of a volcanic eruption, such as the one at Mount Vesuvius, is typically referred to as the pyroclastic flow. During this phase, a mixture of hot gases, ash, and volcanic material rushes down the flanks of the volcano at high speeds, destroying everything in its path.

In the case of the eruption at Mount Vesuvius in 79 AD, the pyroclastic flow was responsible for causing immense devastation and fatalities. It engulfed the nearby cities of Pompeii and Herculaneum, burying them under several meters of volcanic ash and debris.

The most deadly phase of a volcanic eruption, such as the one at Mount Vesuvius, is usually the pyroclastic flow. A pyroclastic flow is a fast-moving mixture of hot gas, ash, and volcanic materials that can reach speeds of up to 450 miles per hour (700 kilometers per hour). It is highly destructive and can wipe out everything in its path.

To learn more about this specific volcanic eruption and its deadliest phase, I can suggest a link to the historical eruption of Mount Vesuvius in 79 AD, which destroyed the cities of Pompeii and Herculaneum:
