Where are the volcanic danger zones int the US?

Answer 1

There are three areas in the United States in which there is volcanic activity. The first is in Hawaii, with the main threat coming from Kilauea, which has been erupting continuously since 1983.
The next zone is the Cascade Volcanic Arc, which stretches from British Columbia to northern California. The volcanoes here are prone to explosive eruptions which are less frequent but potentially more dangerous than kilauea's lava flows. The most notable activity here in recorded history was the 1980 eruption of Mount St Helens.
Finally there is the Yellowstone Caldera, which is the product of a supervolcano in Yellowstone National Park. The chances of an eruption and especially a super eruption in our lifetimes is incredibly small, but hydrothermal activity in the area has claimed a few lives.

Answer 2

Of course, the Pacific Northwest is an active volcano are, along with north California, but perhaps the most dangerous volcano in the US is the one lying beneath Yellowstone Park. This one is about 45 miles across, is mostly underground, and has not erupted for 600,000 years. It erupts about every 600,000 years. If it erupts, much of the United States - the west 1/3 of the US - will simply be wiped off the face of the Earth. Such an eruption could very well kill everything over the entire 48 States, as well.

We should be planning for this, not be pouring billions of dollars into the climate-change hoax.

Answer 3

The west coast (mostly north of San Fransisco) & Yellowstone Park.
