Seismologists are scientists who use many sophisticated instruments to study and try to predict earthquakes. It appears that their instruments are not quite as sophisticated as cats, for there are numerous stories of cats acting frantically and agitatedly shortly before an earthquake occurred.
As the story goes, in China in 1975 seismologists ordered the evacuation of the city of Haicheng based on their observations of cats. The city was evacuated, and the quake hit within a day.
The damage was enormous, of course, but because of the evacuation, many lives were saved. How did the cats “know” a quake was coming? We can only assume they are more sensitive to earth vibrations than are humans—or human technology.
