What else can I help you with?
Can you outrun a pyroclastic flow?
No. A pyroclastic flow can move at well over 100 mph.
What is the term for lava flow that travels downhill at over 100mph?
Pyroclastic flow
Does Krakatoa produce lava or pyroclastic flow?
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.
Why is a pyroclastic flow more dangerous than an earthquake?
An earthquake create a hazard of collapsing buildings and falling objects, which are the greatest threats. So it is quite possible to survive. A pyroclastic flow produces searing temperaturesthat can be well over 1,000 degrees Fahrenheit. You can survive the collapse of a building, but you cannot survive a pyroclastic flow.
Which way does a pyroclastic flow move from a volcano?
A pyroclastic flow moves quickly downhill from a volcano, following valleys and topographic lows. The flow consists of hot gas, ash, and volcanic debris that can reach speeds of over 100 km/h and temperatures of up to 1000°C. It is extremely dangerous and can devastate everything in its path.

An explosive eruption may produce a pyroclastic flow which is?
A pyroclastic flow is and avalanche-like mass of superheated ash, rock, and gas that races down a volcano's slopes at speeds that can reach well over 100 mph. These flows sear everything in their path.

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.
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.
How could a pyroclastic flow from Mt pelee capsize and burn boats in the harbor?
Because it flows over ocean surface at temperatures of 600 to 700 C
A natural disaster produced by a volcano that had killed more people than lava flow is what?
The deadliest phenomenon associated with volcanoes is a pyroclastic flow. Pyroclastic flows are hot masses of ash, rock, and gas that race down the slopes of a volcano, sometimes reaching speeds of well over 100 mph and burning everything in their path.
What is a pyroclastic flow Why are they so dangerous?
Pyroclastic flows are dangerous. They can travel down slope at over 150 mph, somtimes much faster if propelled by a lateral blast. Temperatures inside the flows are often over 1,000 degrees Fahrenheit. Anyone caught in one of these will burn to death.
What are the characteristics and effects of a pyroclastic flow?
A pyroclastic flowFlows that contain high-density mixtures of hot, dry rock fragments and hot gases. sort of spans the volcanic spectrum from pyroclastic material to a lava flow. They flow down the volcano's side at tremendous speeds. One of the most characteristic features of a pyroclastic flow is the "welding" of pyroclastic fragments. These fragments actually are smashed down or compacted because of the high heat within the flows.Pyroclastic flows can result from really explosive eruptions, or they may occur when a thick lava flow collapses down a steep slope. A pyroclastic flow is extremely dangerous. These flows can contain fragments ranging in size from ash to boulders, and they can move at speeds typically greater than 80 kilometers per hour. And if the tremendous speed of these flows is not enough to contemplate, consider this: The temperatures of rocks and gas inside pyroclastic flows is typically between 200°C and 700°C. Yowsa! No wonder pyroclastic flows have caused tremendous devastation throughout recorded history. (from apex)
