Question

i tried reasearching it but i just cant figure out if it is active,dormant,extinct.if you'll can help me i will appreciate it so much oh yeah and 10 big points.

Answer 1

Mount Shasta, a 14,179-foot (4,322 m)[1] stratovolcano, is the second-highest peak in the Cascade Range and the fifth highest peak in California. The mountain is located in Siskiyou County, and has an estimated volume of 108 cubic miles (450 km³), making it the most voluminous stratovolcano of the Cascades.[2] Physically unconnected to any nearby mountain, and rising abruptly from miles of level ground which encircle it, Mount Shasta stands some 10,000 feet (3,000 m) above the surrounding area.

A stratovolcano is a tall, conical volcano composed of many layers of hardened lava, tephra, and volcanic ash. These volcanoes are characterized by a steep profile and periodic, explosive eruptions. The lava that flows from them is highly viscous, and cools and hardens before spreading very far. The source magma of this rock is classified as acidic, or high in silica to intermediate (rhyolite, dacite, or andesite). This is in contrast to less viscous basic magma that forms shield volcanoes (such as Mauna Loa in Hawaii), which have a wide base and more gently sloping profile.
So yes it is active but dormant currently. It is similar to Mt Hood.Mt Rainer,Mt Fuji,Killaminjaro,Mt Pinatubo and Mt Vesuvius.It would send up a lot of smoke and ash but not the type of Lava that the Hawaiian volcanoes put out.
Probably the most famous of these is Mt St Helena in the US.Mt Pinatubo was larger in the Phillapeans. And Mt Vesuvius destroyed the city of Pompei in Roman times.
During the last 10,000 years Shasta has erupted an average of every 800 years but in the past 4500 years the volcano has erupted an average of every 600 years. The last significant eruption on Shasta may have occurred 200 years ago.

Mount Shasta can release volcanic ash, pyroclastic flows or dacite and andesite lava. Its deposits can be detected under nearby small towns totalling 20,000 in population. Shasta has an explosive, eruptive history. There are fumaroles on the mountain, which show that Shasta is still alive.

The worst case scenario for an eruption is a large pyroclastic flow, such as what occurred in the 1980 eruption of Mount St. Helens. Since there is ice, such as Whitney Glacier and Mud Creek Glacier, lahars would also result. Ash would probably blow inland, perhaps as far as eastern Nevada. There is a small chance that an eruption could also be bigger resulting in a collapse of the mountain, as happened at Mount Mazama in Oregon, but this is of much lower probability.

The United States Geological Survey considers Shasta a dormant volcano, which will erupt again. It is impossible to pinpoint the date of next eruption, but it likely will occur within the next several hundred years.

Answer 5

It is an active volcano that erupts about once every 800 until about 4500 years ago when it started erupting about every 600 years. The last time that it erupted was 1786.
