It varies widely. Some volcanoes will erupt every few years or even every few months while others can go hundreds of years without an eruption. Even for one volcano activity is not regular. Major eruptions are often preceded and followed by a series of small eruptions.
There is no record of the Yellowstone volcano erupting on January 12, 2009. The volcano has not had a major eruption for about 640,000 years, but it does experience minor volcanic activity such as geysers and hot springs.
An active volcano is a volcano that has had at least one eruption during the past 10,000 years. An active volcano might be erupting or dormant. An erupting volcano is an active volcano that is having an eruption... A dormant volcano is an active volcano that is not erupting, but supposed to erupt again.
The eruption frequency of geysers varies depending on the geyser. Some geysers erupt on a fairly predictable schedule, such as Yellowstone's Old Faithful which erupts approximately every 90 minutes. Other geysers may erupt less frequently, with some potentially going years between eruptions.
The Yellowstone caldera is not "overdue" for an eruption. You may have heard that the Yellowstone Caldera erupts regularly every 600,000 years and the last major eruption was 640,000 years ago. In reality the caldera does not erupt regularly and as gone as long as 800,000 years without a major eruption.
0.5% to get this you would have to do this 1 divided by 200 = 0.005 then 0.005x100=0.5%
There is no real way of knowing. The volcano produces a super eruption approximately every 600 000 years according to current estimates, but this is with a high degree of variability, with gaps between eruptions of up to 800,000 years. The last super eruption occurred about 640 000 years ago.

About 1 in 730,000. Yellowstones last super volcanic eruption was approx. 640,000 years ago. It's average time between eruptions is 730,000 years. Was a Super Volcano every 600,000 to 800,000 years. That's the scientific numbers, I say maybe a little more dangerous because it erupts every 600-800 thousand years, and it has been 640 thousand already. If we start seeing increased activity and earthquakes around yellowstone then keep an eye on it, but if the volcano activity just settles down and it sleeps for another 150,000 years, don't hold your breath yet.
The cause of St Helens Volcano Eruption in the year 1980 was a 5.1 magnitude earthquake. The volcano didnt erupt for 120 years before this eruption .. so all the magma in the magma chamber had alt of pressure and was pushed out. the volcano was in a position where plates move.

Yes. 100 years is not a long time for a volcano. Some volcanoes will start up again after thousands of years without an eruption.
Chances are that it will not. The volcano has produced three super eruptions in the past 2.1 million years at intervals of 800,000 to 660,000 years. Three eruptions is not enough to set an average pace, but if we were to do so, all we would know is that the volcano stands a fair chance of having a super eruption some time in the next 260,000 years. The last eruption, though not a super eruption, was about 70,000 years ago. On these time scales the chances of an eruption occurring even in the next few hundred years are very small.
It didn't. The Yellowstone volcano last erupted about 70,000 years ago. The last super eruption was about 640,000 years ago.
Not in the slightest. There is NO connection between an eclipse and a volcano. The point is, eclipses happen twice a year or so. Volcanoes go off every few years. Just by sheer coincidence, some volcanoes will erupt during an eclipse. But there is no causal connection between them.
