No scientist has ever predicted a major earthquake, according to the U.S. Geological Survey.
A definitive sign of an impending earthquake, as of 2011, has so far eluded scientists. According to the U.S. Geological Survey, neither they, "nor Caltech nor any other scientists have ever predicted a major earthquake." Despite the lack of scientifically proven signs of an impending earthquake, plenty of anecdotal evidence exists.
Animal Behavior
If old wives' tales are to be believed, strange animal behavior is a sign of an impending earthquake. Many modern reports detail some people's claims that their pets ran away or otherwise acted out of character before an earthquake. According to the USGS, early Greek references report unusual animal behavior before a major earthquake. In the ancient account, rodents, reptiles and some insects fled their homes for safety several days ahead of a major earthquake. The connection between strange animal behavior and increased seismic activity has not been definitively proven. Because of the wealth of anecdotal evidence, some scientists are pursuing this mystery, according to the USGS.
Sensitive People
Some people claim they can sense an earthquake. Those who believe they can predict an impending earthquake report a variety of signs and symptoms that they allegedly experience prior to an earthquake. Commonly reported signs include headaches and a general sense of unease. The USGS says on its website that no scientific explanation exists for those who claim to be sensitive to earthquakes.
Boom Sound
The USGS reports that loud boom-like sounds occur just before and during earthquakes, according to some witness accounts, but no scientific evidence exists to support or explain this phenomenon. Some scientists believe that the "boom" sound could be caused by minor earthquakes that are too shallow to be detected by seismic monitoring equipment, according to the USGS.
Weather
"Earthquake weather" does not exist, despite popular belief and folklore. According to the USGS, earthquakes occur in all types of weather conditions. However, according to the USGS, large low-pressure fronts from major storms, such as hurricanes, could be the catalyst for some earthquakes.
