What are the similarities in a lava flow and a pyroclastic flow?
A lava flow is simply a flow of liquid rock down a slope that usually results from an effusive eruption. A pyroclastic flow is an avalanche-like flow of hot ash, rock and gas that moves down a volcano during an explosive eruption, The move much faster than lava flows and are far more dangerous.
How far did the lava flow in the mount st helens eruption?
The 1980 eruption of Mount St. Helens did not produce lava flows. It was an explosive eruption that prudiced an ash plume and pyroclastic flows. Pyroclastic flows are avalanche-like masses of superheated ash, rock, and gas. Pyroclastic flows from the initial lateral plast reached as far as 19 miles. Ash blown high into the atmosphere was carried by the wind for thousands of miles.
How far did the pyroplastic flow of the 1883 eruption of Krakatoa travel?
it traveld 2500
How far away is mount Pinatubo from Manila?
Mount Pinatubo is currently 1,485 m (4,872 ft). However before the 1991 eruption it was a lot higher at 1,745 m (5,725 ft)
Does Mount Pinatubo have AAA lava?
No. Pinatubo tends to produce ash and pumice rather than lava flows. A'a is a textural variety of basaltic lava. Pinatubo in recent history has erupted dacitic material, which is far more viscous.

How can you survive a pyroclastic eruption?
The best way to survive a pyroclastic eruption is to get far from the volcano, beyond the reach of pyroclastic flows. Stay away from stream channels to avoid mudflows. If you experience heavy ashfall, breath through a wet rag.

Why are more people killed by earthquakes than volcanic eruption?
A number of reasons. There are far fewer major volcanic eruptions than there are earthquakes. Earthquakes have no warning. Most volcanos give warning signs before a major eruption. Earthquakes affect far larger areas, and those areas are more likely to have people living in them. Unless you are near a volcano, *and* in the path of a pyroclastic flow, a blast, or are two stupid to get out of the way of a lava flow, they are unlikely to kill you.

What is the danger in an eruption like mt Pinatubo or mt st helens?
you'd get burned. and you would have to go into the hospital or die or somthing,you would have to run, very very far.

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.
Which is faster a lava flow pyroclastic flow or lahar?
Pyroclastic flows move much faster than lava flows and carry much more momentum. This means there is little time tog et out of the way, and that they can pass over barriers that would stop or deflect lava flows. They can also carry more material. A single pyroclastic flow can bury an area to several meters thick in a matter of seconds.
What damage has Lassen Peak produced?
The most recent eruptive activity occurred at Lassen Peak in 1914-1917 A.D.. This eruptive episode began on May 30, 1914, when a small phreatic eruption occurred at a new vent near the summit of the peak. More than 150 explosions of various sizes occurred during the following year. By mid-May 1915, the eruption changed in character; lava appeared in the summit crater and subsequently flowed about 100 meters over the west and probably over the east crater walls. Disruption of the sticky lava on the upper east side of Lassen Peak on May 19 resulted in an avalanche of hot rock onto a snowfield. A lahar was generated that reached more than 18 kilometers down Lost Creek. On May 22, an explosive eruption produced a pyroclastic flow that devastated an area as far as 6 kilometers northeast of the summit. The eruption also generated lahars that traveled more than 20 kilometers down Lost Creek and floods that went down Hat Creek. A vertical eruption column resulting from the pyroclastic eruption rose to an altitude of more than 9 kilometers above the vent and deposited a lobe of pumiceous tephra that can be traced as far as 30 kilometers to the east-northeast The fall of fine ash was reported as far away as Elko Nevada, more than 500 kilometers east of Lassen Peak. Intermittent eruptions of variable intensity continued until about the middle of 1917.
How often has mt Pinatubo erupted?
A little over 50 times The worst so far was June 15, 1991
