One of the many possibilities is that the deadly fumes and ash can suffocate a person and or persons untli they die from lack of oxygen.
Another is that if they do not doe from suffocation the ash if in a high enough quantity can bury you alive because it can get as deep as 20 feet..
Also, pyroclastic flows are incredibly hot (they can reach temperatures of up to 1,000 °C) so the person would burn in a matter of seconds.
Pyroclastic flows can be of any composition, but are more commonly felsic or intermediate.
Yes, of course Krakatoa has a pyroclastic flow. Every volcano has an pyroclastic flow, which can travel up to at huge speeds. Krakatoa's pyroclastic flow raced an amazing 200 mph over 20 miles of open sea. Yes Krakatoa has pyroclastic flows but not all volcanoes produce pyroclastic flows, only Mt. St. Helens type volcanoes usually composed of andesite. Kilauea for example does not produce pyroclastic flows because it is composed of basalt, the lava flows out easily.
Yes. It is not uncommon for rhyolitic material to form pyroclastic flows.
No, pyroclastic flows typically occur during explosive volcanic eruptions when hot gas and volcanic particles travel rapidly down the side of the volcano. Quiet eruptions, such as lava flows, do not produce pyroclastic flows.
Mauna Loa is a shield volcano, which typically erupts effusively with flowing lava rather than explosively with pyroclastic flows. Pyroclastic flows are more commonly associated with stratovolcanoes.

pyroclastic and convectional.
Lava flows are generally slow moving, giving people time to evacuate. As a result, they do not kill as often as other volcanic hazards such as pyroclastic flows.
The secondary effects of Mount Etna's eruptions include ashfall, lava flows, pyroclastic flows, lahars (mudflows), and volcanic gases released into the atmosphere. These secondary effects can impact local ecosystems, infrastructure, agriculture, and air quality in surrounding areas.
A Pyroclastic Flow can't be stopped!! Even if you're there. If you are any where near a volcano when a Pyroclastic Flow occurs, you will most likely be dead within 30 seconds of seeing it.-Their speed may be as fast as the speed of sound.So Pyroclastic Flows can't be stopped, and aren't stopped.
They are a region. This islands themselves were formed primarily by lava flows. The volcanoes there rarely produce pyroclastic flows.
No. A "quiet" eruption will produce lava flows. Pyroclastic flows generally result from explosive eruptions.
Yes. Pyroclastic flows can contain toxic gasses such as sulfur dioxide.
