I would be outta there - I always remember that feisty old man, Harry Truman, on Mt. St. Helens who had lived there for 50 years and wasn't about to leave. He figured he could weather it out and get rescued after, if need be, by helicopters.
His place was buried underneath 180 feet of ash, debris and 90 feet of water. He, himself, was probable vaporized.
My motto: Always respect Mother Nature.
The wife and I visited Mt. St. Helens on our honeymoon in 2004. A person really cannot grasp the power involved in an eruption like that unless you see it for yourself. Trees 5' in diameter were snapped off like toothpicks about 20' above the ground and were blown uphill, thousands of them. There was a miner's car that they left as an exhibit at one of the turnoffs leading into the caldera area. It was completely flattened, as if it had been crushed in one of those car crushers. I was left stunned by what I saw.....
