What are the dangers of a quiet volcano?
Sudden eruption. Just like the volcano, Mt. Saint Helens.

What year was Mount Saint Helens the volcano born?
Mount Saint Helens like all other volcanoes was created over thousands of years, it started about 37,600 years ago and still continues in it's development. The link below gives far more detailed information.
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.
What type of eruptions does mount st Helens do?
Like most stratovolcanoes, Mount St Helens alternates between explosive and effusive eruptions.

What is the differences between mount st Helens and yellowstone?
yellow stone is a supervolcanowhereas mount saint helens isnt... yellowstone is 1000 times more powerful than mount saint helens which is 2500 times smaler. as yellow stone is a supervolcano and it emmited 240 cubic miles of rock, this means a supervolcano like yellow stone if it erupts can change the temperature of the earth as the debris released blocks the sunlight...potentially causing an iceage with global consuqunces... mount saint helens cant do this and will just cause damage to the place it arupted in the US...
What type of plate boundary caused Mount St Helens?
The cause of Mt. St. Helens' volcanism is due to the subduction melting of the Pacific Plate as it subducts under the North American Plate, located along a convergent plate boundary or fault. No, Mount Saint Helens is not on a hot spot, nor is it on a fault. Mount Saint Helens is part island arc volcanic chain (the Casade Mountaind) due to the subduction of the Pacific Plate under the North American Craton. NOTE: The Farallon Plate is no longer here; it ceased to exist with the end of the Laramide Orogeny some 30 million years ago. The remnants of the Farallon Plate are the Juan de Fuca Plate of British Columbia and northwestern Washington State, and the Cocos Plate of southwestern Mexico. Neither of these microplates has any effect on Mount Saint Helens, which is in southwestern Washington. I found this answer on answers.yahoo.com
What type of lava flow did mt st helens have?
The 1980 eruption of Mount St. Helens did not produce lava flows. It was a plinian eruption that produced aolumn of ash and pyroclastic flows. Pyroclastic flows are avalanche-like masses of hot ash, rock, and gas that rase away from an erupting volcano at speeds that can reachinto the hundreds of miles per hour.
