Anders Herlin, a lecturer at SLU, says to the farming trade paper ATL that there was little to indicate that the cows had any prior knowledge of the quake. Neither did they seem to mind it very much.
All the cows carried equipment, which made it possible to keep track of their behaviour. Out of the 8 cows, only 2 stood up during the quake or just before. Despite the limitations of the study, Herlin believes it is safe to say that cows probably aren’t the most earthquake sensitive animals.
