There are some people, however, who believe they can sense when a major geological event is coming. They claim to be “earthquake sensitive. Sensitivity to the earth’s movements, according to those who say they have it, is revealed in different ways. Some say they are unusually clumsy and keep dropping things and having small accidents just before a big event. Others suddenly have a strong desire to eat popcorn, and don’t know why. Though it may sound crazy, they say it tells them that a big earthquake is less than 24 hours away. The most common sign of an approaching disaster among earthquake sensitive people is said to be a bad headache. Arguably the first person to connect her own headaches to coming geological events was an American woman called Charlotte King. She became famous for her prediction of the eruption of Washington’s Mt. St. Helens on May 18, 1980, when she was accurate to within 12 minutes of the actual event. King was tested by doctors and scientists and found to possess unusual hearing abilities. She could hear sounds in frequencies that most human beings cannot, and claimed to have been hearing such sounds since 1976. Three years later, she noticed that when the sounds changed in pitch or rhythm, giving her unpleasant headaches, a large earthquake would be reported within 72 hours.
