The volcanos of Hawaii are lava producers, those on the West Coast are "Dome Builders" meaning the lava is much denser and flows more like honey than water, it oozes. I doing so it can clog the pipe and blow up (Mout Saint Helens) causing Ash Clouds, Pyroplatic flows and Lahars. 2 different types of volcanos with different behaviors.
Well, something like that. According to USGS, Redoubt has a high silica content which is really fine and prevents gases from venting easily. These types of volcanoes are, apparently, continuously venting gasses except when in a dormant state (examples of dormant volcanoes include Mount Hood in Oregon, Raineer in Washington. St. Helens is, technically, still active.)
Kilauea, in HI, is composed of stone/magma with low silica content, allowing gas to bubble and escape more or less freely. It would be very rare for any Hawaiian volcano "blow up" as St. Helens, Mont Serat, or Redoubt. for this reason.
I live within 200 miles of (recently-active) Redoubt, Spurr, Illiamna, Augustine, Fourpeaked, and (inactive) Double Glacier, Hayes, Douglas. There are another 20-30 volcanoes if you extend that radius to 500 miles.
