9. Fish Jumping En Masse Before Earthquakes
Reports have documented instances where fish exhibit unusual behaviors, such as jumping or erratic movements, prior to earthquakes. For example, during the 1976 Tangshan earthquake in China, fish were observed leaping out of their tanks before the seismic event occurred. This behavior suggests that fish may be sensitive to seismic vibrations or other environmental changes associated with impending earthquakes. (seismosoc.org)
