Answer 1

1 - I'm not familiar with the cascade ranges
2 - If enough dust were produced it may cause the earths temperature to drop for an indefinite period, maybe 1000 years. or more commonly pyroclastic flow or mudflows will destroy farms/towns which usually has a long term effect on people and economies
3 - unsure, maybe sulphur dioxide
4 - Hawaii
5 - increased gas release around volcano, increase in the gradient of volcanic dome (bulging), increase in the frequency of earthquakes

Answer 3

What have you found in your websearching? Is it really that hard to use a search engine?

http://en.wikipedia.org/wiki/Cascade_Range

Mount St. Helens is certainly one active volcano in the Cascades

One obvious volcano not on a plate boundary is Kilauea
