What is the example of quiet and violent eruptions of volcano?
An example of a "quiet" eruption would be the 1983-present eruption of Kilauea in Hawaii. A violent eruption would be the 1980 eruption of Mount St Helens.
How likely would it be to see an eruption from mount saint helens?
Very Unlikely
Which volcano blanketed many states with ash?
Ash from Mount St. Helens eruption was detected in several states but "blanketed" would be an overstatement.
Why do some volcanoes erupt ash and others lava?
The style of the volcanic eruption is very dependent on the amount of dissolved gas that is in the magma (liquid rock below the surface). If there is a high gas content the volcanic eruption will be explosive and create a log of ash. If the gas content is low the eruption produces more lava flows. An example of a high gas content eruption was the last major eruption of Mt. St. Helens in 1980. An example of a low gas content eruption would be the Hawaiian volcanoes.
When did the last volcano erupt in the US?
Currently that title goes to Kilauea in Hawaii, which has been erupting almost continuously since 1983. The last volcano to initiate an eruption was Mount Pavlof on the Alaska Peninsula, which produced a small eruption in June 2014.
On a scale of 1 to 10 what would the St Helens eruption be?
The 1980 eruption of Mount St. Helens, a stratovolcano located in Washington state, in the United States, was a major volcanic eruption. It rated a 5 on the Volcanic Explosice Index, which rates volcanic eruptions from 1-10.
When and where was the last major eruption in the US?
The last major eruption in the US was the 1980 eruption of Mount St. Helens in Washington. This eruption resulted in significant damage to the surrounding area and was one of the most destructive volcanic events in US history.

Is mount st helens still eruptive?
Its last eruption was in the 2000s so yes I would say so. It had a very big eruption in 1986. Just did a report on it. :)

Ash from Mount St. Helens eruption was detected in several states but "blanketed" would be an overstatement.
What intensity is mount st Helens?
If the question is referring to the explosive intensity of Mt. St. Helens, it would depend on the eruption that you are referring to. In regards to the most well known eruption in historical times (May 18, 1980) it is registered by the United States Geological Service as a Volcano Explosivity Index 5 (VEI 5). Which is a very powerful eruption compared to how often they occur.

Why would a volcanic eruption be most likely occur in the state of Washington?
There are several volcanoes in Washington, a few of which have already had eruptions in recorded history, most famously the 1980 eruption of Mount St Helens. Washigton's volcanoes are a result of the Cascadia Subduction Zone, where two of Earth's tectonic plates collide.
