A lot of the disaster scenarios that you discuss involve earthquakes. Please note that the Richter Scale became obsolete in the 1970's. It gives unreliable results above a 6.0. The currently used scale is the Moment Magnitude Scale.
Even though the popular press likes to throw around the term "Richer Scale" concerning earthquakes, remember these people are generally uneducated in science and too lazy to check their facts. Quite frankly, old boy, I expected better from you and I'm not a Geophysics expert either.
Remember there are a lot of us "baby boomers" out there who studied a lot of really hard science in the 60's and 70's and mistakes like these stick out like a sore thumb and undercut your believability.
