Keywords:Stranding, Earthquake, Kashima-Nada, Geomagnetic disturbance

A mass stranding of Melon-headed whales (Peponocephala electra) occurred at the Kashima-Nada beach, Japan, seven days before the 2011 M9.0 Off the Pacific coast of the Tohoku Earthquake (Tohoku EQ). Kashima-Nada beach is located 300 km southwest of the epicenter. Some people said that the mass stranding might be a precursor of the Tohoku EQ. In this study, we performed statistical analyses to determine the level of correlation between strandings at the Kashima-Nada beach and EQs. We concluded that the mass stranding was not correlated with the Tohoku EQ.
