Forecasting major climactic and geologic events by observing animal behavior in the wild is a way of life for nature-based cultures. Modern science, however, has largely ignored the potentially life-saving value that could be derived from studying Nature’s early warning system.

Now, however, increasing numbers of researchers are employing the scientific method – along with advanced technology – to quantify the necessarily anecdotal evidence of changes in animal behavior in advance of a significant event. They are also seeking to arrive at a consensus regarding causation.

In our 12/22/14 article, we reported that tiny golden warblers – equipped with electronic tracking devices – surprised scientists by anticipating and fleeing a tornado the day before it struck. This month, Time Magazine carries a report about an international team that analyzed records from motion-triggered cameras in Peru’s Yanachaga National Park during the month prior to a 7.0 magnitude earthquake that struck in the Peruvian Andes.

The cameras were running 24/7 for the 30 days prior to the quake. Animal sightings diminished week-by-week and in the final five to seven days, disappeared altogether.

The best guess, at present, as to how the animals ‘know’ so far in advance of technologically extended human perception relates to their sensitivity and reactivity to “positive airborne ion injection at ground-to-air interface.” This is a phenomenon that accompanies the build-up of pressure on the Earth’s surface just prior to a quake.
