PLANET EARTH — The most explosive volcanic eruptions spit out a fast-moving and incredibly destructive mass of material known as a pyroclastic flow.
Should you ever find yourself in the path of one, you should run in the opposite direction as quickly as possible, according to the United States Geological Survey.
Pyroclastic flows are made up of a basal flow of volcanic ash, lava, rock and gases, which move beneath a cloud of ash. Their temperatures can exceed 1,000 degrees Celsius, and they can move at 700 kilometers per hour.
Typically, pyroclastic flows move downslope but they can go uphill when the ratio of gas to ash is higher, according to Forbes. This is known as a pyroclastic surge.
These dense pyroclastic surges can even move over water.
Pyroclastic flows generally destroy everything in their path including vegetation, buildings and people.
There are generally two kinds of pyroclastic flow. The first type forms when an eruption column cools and the ash becomes too dense to maintain an upward thrust.
The second type is rarer and occurs when so much pressure builds up inside a volcano that it erupts laterally and boils over.
The last known example of this is when Mount St. Helens in Washington state erupted in 1980.

Many people do think that most people are killed by lava streams when there is a volcano errupting, but thats not correct.
Most people do get killed by pyroclastic flows and gasses that do come with those.

Dirty thunderstorm
From Wikipedia, the free encyclopedia
Volcanic lightning above an eruption of Mount Rinjani.
A dirty thunderstorm (also volcanic lightning) is a weather phenomenon that is related to the production of lightning in a volcanic plume.[1]
A famous image of the phenomenon was photographed by Carlos Gutierrez and occurred in Chile above the Chaiten Volcano.[2] It circulated widely on the internet.
Other instances have been reported above Alaska's Mount Augustine volcano,[3] Iceland's Eyjafjallajökull volcano[4] and Mount Etna in Sicily, Italy.[5]
Causes[edit]
A study in the journal Science indicated that electrical charges are generated when rock fragments, ash, and ice particles in a volcanic plume collide and produce static charges, just as ice particles collide in regular thunderstorms.[6]
Volcanic eruptions are sometimes accompanied by flashes of lightning. However, this lightning doesn’t descend from storm clouds in the sky. It is generated within the ash cloud spewing from the volcano, in a process called charge separation.
As the plume started going downwind, it seemed to have a life of its own and produced some 300 more or less normal [lightning bolts] ... The implication is that it has produced more charge than it started with. Otherwise [the plume] couldn't continue to make lightning.
—Martin A. Uman, co-director of the University of Florida Lightning Research program
Volcanic eruptions also release large amounts of water, which may help fuel these thunderstorms.

Pyroclastic flows from volcano Merapi killed 350 people and several 1000 animals in 2010. In this video you will see a pyroclastic flow which burned a cow and a man in a hospital who was injured seriously by pyroclastic flows.
What is a pyroclastic flow? A pyroclastic flow is a searing cloud of volcanic ash, lava blocks and hot gases. Pyroclastic flows move like an avalanche down the slope of the volcano and can be faster than a Formula 1 car. Nothing can stop a pyroclastic flow.
Of all the volcanic hazard pyroclastic flows are the worst, closely followed by lahars. At the volcano Merapi I could film a lahar. The video you see here: http://youtu.be/TpwiFtVRBTs
Spectacular are my shots of pyroclastic flows at the volcano Sinabung on Sumatra: http://youtu.be/wsu8DPeer-o
Merapi is one of Indonesia's most active volcanoes. It lies in one of the world's most densely populated areas. The volcano dominates the landscape north of the city of Yogyakarta. It is the youngest and southernmost of a volcanic chain extending NNW. Growth of the older Merapi volcano during the Pleistocene ended with major edifice collapse.

The Soufriere Pyroclastic Flow is a type of granitic explosive eruption where the pressure of an eruption cloud fails to hold up the ash and it collapses as a pyroclastic flow. This experiment is easy to create, just put some dry ice and water into a bowl, soak a strip of cloth in dishwasher detergent, and contain the CO2 into one big bubble.

The pyroclastic flow deposits red-hot material on the slope of the volcano. After a few minutes, air heated by the deposit establishes a convective regime and due to the speed of the rising air a series of small tornados (also spelled tornadoes) are formed.
During daylight it is difficult to imaging how hot the deposit is. To see a pyroclastic flow deposit glowing at night from same location as present video one can view:

Note: Video is played at 2x normal speed as flow is actually not very fast and video would otherwise be too long for most viewers.

Pyroclastic flow
A pyroclastic flow (also known scientifically as a pyroclastic density current) is a fast-moving current of hot gas and rock (collectively known as tephra), which reaches speeds moving away from a volcano of up to 700 km/h (450 mph). The gas can reach temperatures of about 1,000 °C (1,830 °F). Pyroclastic flows normally hug the ground and travel downhill, or spread laterally under gravity. Their speed depends upon the density of the current, the volcanic output rate, and the gradient of the slope. They are a common and devastating result of certain explosive volcanic eruptions.
Origin of term
The word pyroclast is derived from the Greek πῦρ, meaning "fire", and κλαστός, meaning "broken in pieces". A name for some pyroclastic flows is nuée ardente (French for "Glowing Cloud"); this was first used to describe the disastrous 1902 eruption of Mount Pelée on Martinique. In the dark, these pyroclastic flows glowed red.
Pyroclastic flows that contain a much higher proportion of gas to rock are known as "fully dilute pyroclastic density currents" or pyroclastic surges. The lower density sometimes allows them to flow over higher topographic features or water such as ridges, hills, and sea. They may also contain steam, water and rock at less than 250 °C (482 °F); these are called "cold" compared with other flows, although the temperature is still lethally high. Cold pyroclastic surges can occur when the eruption is from a vent under a shallow lake or the sea. Fronts of some pyroclastic density currents are fully dilute; for example, during the eruption of Mount Pelée in 1902 a fully dilute current overwhelmed the city of Saint-Pierre and killed nearly 30,000 people.

Dirty thunderstorm
From Wikipedia, the free encyclopedia
Volcanic lightning above an eruption of Mount Rinjani.
A dirty thunderstorm (also volcanic lightning) is a weather phenomenon that is related to the production of lightning in a volcanic plume.[1]
A famous image of the phenomenon was photographed by Carlos Gutierrez and occurred in Chile above the Chaiten Volcano.[2] It circulated widely on the internet.
Other instances have been reported above Alaska's Mount Augustine volcano,[3] Iceland's Eyjafjallajökull volcano[4] and Mount Etna in Sicily, Italy.[5]
Causes[edit]
A study in the journal Science indicated that electrical charges are generated when rock fragments, ash, and ice particles in a volcanic plume collide and produce static charges, just as ice particles collide in regular thunderstorms.[6]
Volcanic eruptions are sometimes accompanied by flashes of lightning. However, this lightning doesn’t descend from storm clouds in the sky. It is generated within the ash cloud spewing from the volcano, in a process called charge separation.
As the plume started going downwind, it seemed to have a life of its own and produced some 300 more or less normal [lightning bolts] ... The implication is that it has produced more charge than it started with. Otherwise [the plume] couldn't continue to make lightning.
—Martin A. Uman, co-director of the University of Florida Lightning Research program
Volcanic eruptions also release large amounts of water, which may help fuel these thunderstorms.

Pyroclastic flows from volcano Merapi killed 350 people and several 1000 animals in 2010. In this video you will see a pyroclastic flow which burned a cow and a man in a hospital who was injured seriously by pyroclastic flows.
What is a pyroclastic flow? A pyroclastic flow is a searing cloud of volcanic ash, lava blocks and hot gases. Pyroclastic flows move like an avalanche down the slope of the volcano and can be faster than a Formula 1 car. Nothing can stop a pyroclastic flow.
Of all the volcanic hazard pyroclastic flows are the worst, closely followed by lahars. At the volcano Merapi I could film a lahar. The video you see here: http://youtu.be/TpwiFtVRBTs
Spectacular are my shots of pyroclastic flows at the volcano Sinabung on Sumatra: http://youtu.be/wsu8DPeer-o
Merapi is one of Indonesia's most active volcanoes. It lies in one of the world's most densely populated areas. The volcano dominates the landscape north of the city of Yogyakarta. It is the youngest and southernmost of a volcanic chain extending NNW. Growth of the older Merapi volcano during the Pleistocene ended with major edifice collapse.

The Soufriere Pyroclastic Flow is a type of granitic explosive eruption where the pressure of an eruption cloud fails to hold up the ash and it collapses as a pyroclastic flow. This experiment is easy to create, just put some dry ice and water into a bowl, soak a strip of cloth in dishwasher detergent, and contain the CO2 into one big bubble.

The pyroclastic flow deposits red-hot material on the slope of the volcano. After a few minutes, air heated by the deposit establishes a convective regime and due to the speed of the rising air a series of small tornados (also spelled tornadoes) are formed.
During daylight it is difficult to imaging how hot the deposit is. To see a pyroclastic flow deposit glowing at night from same location as present video one can view:

Note: Video is played at 2x normal speed as flow is actually not very fast and video would otherwise be too long for most viewers.
