Bears Show Restlessness Before Major Events
Bears become unusually active before earthquakes or volcanic eruptions. Alaska park records documented bears roaming strangely before the 2002 Denali earthquake. Their sensitive paws detect ground tremors while their keen noses pick up atmospheric changes. Some hibernating bears have even awakened early when seismic events threatened their dens. Wildlife researchers increasingly include bear behavior in their studies of animal responses to impending natural disasters.
