False for example Mount Shasta is still considered an active volcano but erupted in the 1700s
Composite volcanoes erupt the most violently.
They did, that is how the islands formed. But most of the volcanos are extinct and no longer erupt.
No. That would be a major news story should it start. Millions of people live in the area around Vesuvius . It is one of the most watched volcanos in the world.
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.
Stromboli Volcano, off the west coast of southern Italy, has been erupting nearly continuously for over 2,000 years.
There are three types of volcanos, shield, cinder, and composite volcanos. Cinder volcanos are the smallest, while shield volcanos are the largest. Composite volcanos are the most dangerous and the most explosive.
the one that just had
Hawaii
There are severel volcanos that are showing activity and the eruption maybe ongoing from the year 2007. You can find them all on the website http://www.infoplease.com/ipa/A0763388.html. I hope this was a good enough answer for you.
Because they are
they are most likely to form were the plates of the earth are most active ... like Hawaii.
Shield volcanoes erupt least violently cinder cone most violently and compost can erupt either way.
