Why does volcanic activity happen in the Lassen volcanic national park?

Lassen Volcanic National Park is centered on Lassen Peak, a volcano that is part of the Cascade Volcanic Arc, which stretches from northern California to southern British Columbia. The volcanic acivity here is a result of the Cascadia Subduction Zone, a boundary where two of earth's tectonic plates meet off the Pacific coast. Here, the Juan De Fuca Plate, located under the Pacific Ocean is slowly sliding into and under the North American Plate, taking some seawater with it. The seawater seeps into the hot rocks of the mantle, causing some of them to melt into magma and rise through ths crust, forming volcanoes.

What would happen if there was no volcanic activity on earth at all?

Why is New York state unlikely to have a volcanic eruption?
There are not tectonic plates near by and that's where volcanic activity is prone to happen
Can plants live on a caldera?
Yes. After volcanic activity has calmed down a caldera can become a perfectly habitable place, at least until volcanic activity resumes, which in some cases does not happen for hundreds, even thousands of years.
What countries or states did volcanic activity happen?
Mt. St. Helens, washington. erupted: may 18th 1980
Volcanic activity how does it happen?

Where does an earthquake and volcanic activity often take place?
Earthquakes and volcano activity occurs at the boundaries or edges of the tectonic plates.
Is there any volcanic eruptions in Mars?
yes! volcanic eruptions happen on mars NASA
What is post volcanic phenomena?
post-volcanic phenoma are the things which happen before an eruption.
What would happen if the continents smashed back together?
Some of this is already happening: India is smashing into Asia, building the extremely high Himalaya mountains. In some places it is likely that a period of extreme volcanic activity might happen too.
Do volcanic eruptions happen on islands?
Yes.
Why do volcanic eruptions happen mostly in Hawaii japan and Yellowstone?
They don't. Earth averages about 50 volcanic eruptions on land each year in many locations around the world. Yellowstone has not experienced a volcanic eruption in thousands of years. This activity is attributed to a n area of especially hot mantle called a hot spot melting rock beneath the crust. Hawaii is notable for the presence of Kilauea, which has had a single eruption ongoing since 1983 and so attracts a great deal of attention. This activity is dues to a hot spot. Japan sees a fair amount of volcanic activity due to the convergence of several of earth's tectonic plates. Hawaii, Japan, and Mount Etna in Sicily are probably the most volcanically active sites in developed nations. Other volcanic zones with high activity include the Andean volcanic belt in western South America, Indonesia, the Aleutian Arc in Alaska, and the East African Rift.
