Yosemite National Park does not actually contain a volcano, but Yellowstone National Park does. It is an extremely active volcano, and it is still uncertain when it will erupt again but it has been hundreds of thousands of years.
Scientists haven't put out an estimated time yet. They have been saying that it won't erupt any time soon and that the recent hastened growth of the caldera was just a big lava bubble (to put in lay man's terms) that is rising up. So, no big super volcano yet.
yes it might, we don't know it was supposed to erupt 40 years ago, but it didn't, it erupts every 6,000 years, now it erupted already 640,000 years ago!
tomorrow night!
yes it will
It varies from volcano to volcano. The super volcano under Yellowstone National Park erupts an average of once every 600,000 years. Others may erupt once, then go extinct. Others may erupt once a century.

Yellowstone National Park is a super volcano. Yellowstone is over a "hot spot" which is why there are geysers there. The hot spot blew millions of years ago leaving a caldera where the geysers are. Yellowstone is a volcano but do not go expecting an eruption unless you can wait a few million years.
Any of the volcanoes around Portland and Seattle could blow at any time. In Alaska, volcanoes are erupting quite regularly. It is really difficult to tell which US volcano is likely to erupt, next. But . . . Mt. Rainier, in the Seattle area, is expected to erupt in our lifetimes, and the immense volcano in and under Yellowstone Park could erupt at any time. There are a couple of volcanos in northern California that could erupt, as well.
This is described as a dormant volcano (neither active nor extinct).

The best super volcano is most likely the "hidden" volcano in Yellowstone park.
The entire park of Yellowstone rest on a super volcano
The super volcano at Yellowstone National Park is 35 miles by 45 in diameter. It is one of the largest volcanoes in the world and when it does erupt it will likely cause a mass extinction.

A volcano is a vent or reupture in the Earth's crust through which lava, ash, and gas can erupt. Yellowstone is a national park in the United States known for its hot springs and geysers. The park is the site of a massive caldera associated with a supervolcano.
Its because of the super volcano under Yellowstone park
A few miles under Yellowstone is an enormous magma chamber associated with a supervolcano.
No, it's main feature -- Yosemite Valley -- was created due to glacial erosion.
