How old is Mt Helens?
Not as volcanoes go: it is about 40,000 years old and continues to change, erupting violently at least three times in the last 500 years.
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.
Is Mt St Helens a shield cinder cone or composite volcano?
No. In terms of the size of the structure itself, the largest volcano on Earth is Mauna Loa, which makes up the majority of the volume of the isaldn of Hawaii (the big island). The largest volcano known to science is Olympus Mons on Mars. The tallest volcano on Earth in terms of elevation is Ojos de Salado on the Chile-Argentina border at 22,615 feet. By comparison Mount St Helens is at 8,365 feet (9,677 before the 1980 eruption). Mount St Helens did not produce the largest eruption either. The largest volcanic eruption in recorded history was the 1815 eruption of Mount Tambora in Indonesia, which was on the order of 100-200 times larger than the 1980 eruption of Mount St Helens.

What type of plate boundary in mt st helens when it erupted in 1980?
The Cascade Mountains in Oregon and Washington (including Mount St. Helens) are created by the subduction of the Juan de Fuca plate under the North American Continental Plate.See Wikipedia:http://en.wikipedia.org/wiki/Juan_de_Fuca_Platehttp://en.wikipedia.org/wiki/Cascade_VolcanoesEssentially all of the volcanoes in the Cascade Range are still considered active. Mt St. Helens is considered the most active with the large eruption in 1980, followed by numerous small "cone building" eruptions.The Three Sisters have had major lava flows every few thousand years, and Mt. Mazama had a major eruption about 7,000 years ago followed by numerous small cone-building eruptions. They could all have future eruptions.The following images are from the above Wikipedia Article, and were originally produced by the USGS and entered into the public domain.
