Hello.

I'm going to talk about another show I saw just now and it was about Pompeii.
For those of you who haven't heard of Pompeii, it was a Roman city that was covered in ash and pumas. ( pumas is a type of rock that can float )

The guy who was in it was talking about how and why the Romans were trapped when the volcano, Mount Vesuvius, went off with a bang.

The reason why all of the people where trapped was that the town that they were living in had been broken up by an Earthquake a few weeks before, and thus they were rebuilding their town.
When Vesuvius did blow it's top, instead of trying to get as far away as possible, they stayed where they were and saw the volcano as a form of entertainment, sort of like when you're at home watching the TV in the afternoon after school, or something like that.

The surprising thing is, they weren't killed by magma or anything like that, instead, they were killed by falling rocks, breathing in ash and the pyroclastic flow.
A pyroclastic flow is a mixture of hot gas and rock. You can read about it here.
