Document Summary
Any consideration of natural disaster or catastrophe deals with energy; two energy sources are possible: energy internal to the earth. Internal heat energy is responsible for processes such as earthquakes, tsunamis, volcanic eruptions: energy external to the earth, hurricanes, climate change, and asteroid impacts. If all the tests pass theory allows you to make a prediction of the end result proper explanation of the whole process. **useful prediction, but does not absolutely prove that there is no possibility of a rude poodle. As soon as one is spotted by an observer, the theory falls apart. I. e. , a heavy fall of wet snow of a steep mountain slope may be a hazard, unless an avalanche occurs and great infrastructure damage or deaths result, there is. Examples: earthquake in mexico city two closely spaced buildings swayed and banged together causing the middle to completely collapse. Occupants were killed, but considered a local disaster.
