There is no reason to believe Yellowstone will erupt any time in the next century.
It didn't. The Yellowstone volcano last erupted about 70,000 years ago. The last super eruption was about 640,000 years ago.
because smoke comes out of the volcano
no
As often as it wants. It all depends on how much pressure is building up underneath it.
A tree fell down and touched the volcano so the volcano started erupting.
There is no scientific evidence to suggest that Yellowstone will erupt in 2018. The volcano is closely monitored by experts, and any potential eruption would likely be preceded by warning signs.
I consider an eruption in Yellowstone in 2012 VERY unlikely, mostly because it's now 2013.
the difference from a volcano to a mountain is that a vocano erups but a mountain doesnt.
It is extremely unlikely. Currently, there is no indication that something is developing.
Yes. It erupted 3 time in the last 2.1 million years
Yellowstone's last magma eruption was about 70,000 years ago. The last super eruption was approximately 640,000 years ago.
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.
