Many people believe that the occurrence of earthquakes and the weather are related; that there were more earthquakes when the weather was humid. But to date, there has been no scientific evidence to prove such an assertion. As for the relationship between the occurrence of earthquakes and season, in Taiwan, most earthquakes occur from September to January, followed by June. In terms of location; in Taipei area, there are more earthquakes in September and less in June; for the Hsinchu area, there are more earthquakes in November and less in February and March; for the Hualien area, there are more earthquakes in October and November, and less in June and July; whereas in Tainan and Taitung, there are more earthquakes in December. However, no scientific basis for such earthquake frequency and its relationships with the season has so far been proven.
