How does an explosive eruption products a pyroclastic flow?
During an explosive eruption, a volcano sends out superheated ash, gas, and rock. Depending on the nature of the eruption, pyroclastic flows can develop in three ways:A lateral blast directly ejects the flow, though this is a rather rare event. In another scenario, dense pyroclastic material erupts and spills out of the vent or over the crater rim. In still other cases a vertical eruption column collapses and material flows downhill.In all cases the flow involves a mass of ash, rock, and gas that is too dense to rise on its own, and instead hugs the ground.Most pyroclastic flows are produced during explosive eruptions of stratovolcanoes.
Is it possible to survive to a pyroclastic flow?
It is very unlikely. One of the few survivors of a pyroclastic flow was a man named Ludger Sylbaris. In 1902 he was sent to prison in the city of St Pierre on the French colonial island of Martinique. Not long afterward the nearby volcano Mount Pelee erupted, sending a pyroclastic flow in the the city, leaving Sylbaris as one of only two survivors in the city of over 30,000. Sylbaris was shielded from the worst effects of the flow by his jail cell, but he still suffered 3rd degree burns.
Why do pyroclastic flows have a higher percentage of deaths than lahars?
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.

How caves were formed?
They - or it? - are normal karst caves, formed in limestone by its dissolution by water. I believe they still carry a stream: if so they are still forming.

What is material left from an explosion?
Well, being that the explosion, if it is a large one, would have bits and pieces of shrapnel. It could be scraps from a building, whether the building is made with glass, or metal, or aluminum. Also, there will be dust, and debree, possibly smoke hovering, in, and around the explosion site. Something also, to look out for, are small, still-burning fires, around the explosion site. (It depends on how the explosion was started. I hoped that I helped answer your question!
