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.
Not only the largest be the only volcano to erupt in the U.S. mainland in the past 50 years was Mount St. Helens.
There is no fixed length to an erruption, it varies from volcano to volcano. a volcano can erupt in days or more than its depend on its manner .
Mount St. Helens (May 18, 1980) in southwest Washington state is the most recent volcanic eruption in the continental US. In Hawaii, Mauna Loa has erupted more recently (1984) and Mount Kilauea has continued to erupt since 1993.
Predicting volcanic eruptions although part of the science of volcanology is the most difficult thing to successfully accomplish. The times between eruptions of volcanoes varies, and does not follow an exact pattern or time frame between eruptions. The only way that scientists have an idea of when a volcano will next erupt is when the volcano starts showing signs of unrest, and than it still depends heavily on what types of unrest the scientists are witnessing.

I think it was in Hawaii.

The volcano of 1350BC erupted and destroyed the entire park. It caused a year long winter over most of North America from shore to shore, and even in Europe. The volcano at Yellowstone WILL erupt again; it's not an if but a when. When it blows, scientists estimate that it will destroy most of the western half of the US and probably North America and cause major weather changes across the globe.
The Canary Island of Lanzarote has a volcano which it said to be on the precipice of falling in to the sea, should this erupt and happen it would cause a massive Tsunami which would cross the Atlantic Basin and likely reach the US East coast.

Yes. Volcanic eruptions are often preceded by earthquakes, venting of steam and gas, and very slight change to the shape of the volcano. Large eruptions are often preceded by smaller eruptions.

hawaii
no ok this is sparkledawn correcting that guy, there are active volcanoes in Hawaii, the most active volcano in the us is there!Yes there are, the whole island was made from erupting volcanos and they still erupt causing the islands to get bigger.Yes There are quite a few! The most active volcano in the world, Kilauea, is located there.
Recently, a volcano has erupted in Iceland. It has affected us mildly, but scientists are currently predicting that the volcano that has already erupted is still active, and a volcano 50 times bigger next to it might erupt. Don't be frightened, these are just predictions! The active volcano has cut of many airlines flying into Great Britain. Thousands of tourists have been stuck camping out in airports, desperate to get home, and others are awaiting for their plane to take them to their holiday destination to arrive. Also, and I have evidence for this, when the volcano erupted, the day after that I woke up to see grey/black ash all over my car bonnet and windscreen. When the volcano erupted, all the lava leaked into the sea, so it was quite dangerous to take a ferry around that area. As Great Britain is the nearest county to Iceland, we are the most affected country. But the amount of volcanic ash is reducing, and now it is safe to go on a plane and venture round in a boat, but let's just keep our fingers crossed this next volcano won't erupt!
