Earthquake prediction? How to predict earthquakes? What methods and signals can accurately foretell quakes? These are some questions scientists try to answer since centuries without any success. Animal behavior? Little tremors? Weather changes? Seismographs? Magnetic field? Earth ionosphere? All have fallen short.
Now scientists are looking at waves and electricity that might be related to the fault activity. Indeed, it seems that just before a large earthquake, the rock starts to change and produces huge electrical currents: 100,000 amperes and up to a million amperes for a magnitude 6, resp. a magnitude 7 earthquake. These currents are measured by magnetometers along fault lines in California, Peru, Taiwan, and Greece which can detect magnetic pulses from electrical discharges up to 10 miles (16 kilometers) below the Earth’s surface. On a normal day in California, the magnetometers record around 10 pulses (the fault is always moving) whereas up to 200 pulses are measured during the two weeks before large earthquakes.
You will of course tell me that magnetic pulses can be created by many other things such as rainy weather, lightning, solar flares, but also machine engines, and this is true. But, I think this way of predicting earthquake is rather very interesting. Give me your opinion on this article. Maybe we can come up with a plausible explanation!
