Though many stories from around the world describe behavioral changes in various animals in the days and hours before an earthquake, research testing animals’ ability to predict earthquakes has been rare.

Though many stories from around the world describe behavioral changes in various animals in the days and hours before an earthquake, research testing animals’ ability to predict earthquakes has been rare. Recently, however, scientists were able to document the behaviors of a group of toads(蟾蜍) before, during, and after an earthquake. Researchers were studying the breeding(配種) habits of a particular group of toads, when, suddenly, 96 percent of the males simply disappeared for a five-day period. A significant earthquake and several aftershocks occured on the fifth day after the departure. Six days after the last aftershock, the males returned and resumed mating, as if nothing had happened. It turns out that prior to the earthquake, there had been subtle(微妙的) changes in the Earth’s magnetic field, and an increase in the amount of radon gas(氡氣) in the groundwater. Additionally, there were unusual electrical disturbances in the upper atmosphere.

儘管來自世界各地的許多故事都描述了地震前幾天和幾小時內各種動物的行為變化，但研究測試動物預測地震的能力卻很少見。然而，最近，科學家們能夠記錄一組蟾蜍在地震前、地震中和地震後的行為。研究人員正在研究一組特定蟾蜍的繁殖習性，突然間，96% 的雄性蟾蜍在五天內消失了。出發後第五天發生了大地震和多次餘震。最後一次餘震發生六天后，雄性返回並恢復交配，彷彿什麼也沒發生。原來，地震前，地球磁場發生了微妙的變化，地下水中氡氣的含量有所增加。此外，高層大氣中存在異常的電擾動。
