At 12 years of age, my whippet has settled into a routine sufficient that I can walk him off-lead, but not on the road between our house and the park. A fault runs directly underneath that road; the asphalt is still fractured after the quakes as the eastern side has been raised. My dog’s behavior is peculiar - tense - there. Perhaps he feels some type of magnetism created by tectonic strain that humans cannot.
The catfish is a symbol of earthquakes in Japan as behavioral anomalies supposedly predict imminent temblors. Another fish with supposed similar properties is the oarfish. Normally a deep-sea dweller, its appearance in shallow waters has traditionally been a harbinger of quakes. CNN writes that two have recently been netted in the northern prefecture of Toyama. It’s probably nothing but worth keeping an eye on if just to judge how well non-human species can sense seismic activities. - William
