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.

for one, it is a volcano, and they usually erupt when they are over a hot spot.
Most likely. The volcano has continued to erupt regularly since its last massive explosion in 1883.

It can be called an active, dormant or extinct volcano. An active volcano erupts regularly and frequently, however, it might not erupt at some times. A dormant volcano rarely erupts. Therefore, it does not erupt for most of the time. An extinct volcano does not erupt anymore.
Most volcanoes are active for a long time before dieing. So no an average volcano erupts more than once in its lifetime.

A volcano can erupt twice or even an infinite number of times. Most volcanoes erupt many times over their lives.
