No references to animals walking in circles in any religious texts I can find. Pretty weird.

I check this site daily.

I don't really see a rise in large earthquakes on the west coast. What we had was an unusual lull in seismic activity, which creates more pressure on the faults, which results in big quakes instead of the dozen small ones we usually have.

Animals & Earthquake Prediction

The earliest reference we have to unusual animal behavior prior to a significant earthquake is from Greece in 373 BC. Rats, weasels, snakes, and centipedes reportedly left their homes and headed for safety several days before a destructive earthquake. Anecdotal evidence abounds of animals, fish, birds, reptiles, and insects exhibiting strange behavior anywhere from weeks to seconds before an earthquake. However, consistent and reliable behavior prior to seismic events, and a mechanism explaining how it could work, still eludes us. Most, but not all, scientists pursuing this mystery are in China or Japan.
We can easily explain the cause of unusual animal behavior seconds before humans feel an earthquake. Very few humans notice the smaller P wave that travels the fastest from the earthquake source and arrives before the larger S wave. But many animals with more keen senses are able to feel the P wave seconds before the S wave arrives. As for sensing an impending earthquake days or weeks before it occurs, that's a different story.
A once popular theory purported that there was a correlation between Lost Pet ads in the San Jose Mercury News and the dates of earthquakes in the San Francisco Bay area. A thorough statistical analysis of this theory, published in California Geology in 1988, concluded that there was no such correlation, however.
Another paper published in a scientific journal in the U.S. on this subject by a respected scientist in 2000 is summarized here...
The paper poses this question: Is it reasonable for a seismic-escape behavior pattern to evolve, and can such a genetic system be maintained in the face of selection pressures operating on the time scales of damaging seismic events? All animals instinctively respond to escape from predators and to preserve their lives. A wide variety of vertebrates already express “early warning” behaviors that we understand for other types of events, so it’s possible that a seismic-escape response could have evolved from this already-existing genetic predisposal. An instinctive response following a P-wave seconds before a larger S wave is not a “huge leap”, so to speak, but what about other precursors that may occur days or weeks before an earthquake that we don’t yet know about? If in fact there are precursors to a significant earthquake that we have yet to learn about (such as ground tilting, groundwater changes, electrical or magnetic field variations), indeed it’s possible that some animals could sense these signals and connect the perception with an impending earthquake.
However, much research still needs to be done on this subject. The author suggests establishing a baseline behavior pattern that can be compared with reactions of various environmental stimuli, and then testing various potential stimuli in the laboratory. Of course, the presence of these stimuli still needs to be researched with regard to precursory phenomena preceding an earthquake, for if these signals aren’t present in the environment before an earthquake, a connection is irrelevant.

Maybe Alaska was not such a good choice for your survival thingie.

I haven't noticed animals reacting to seismic activity. Pretty sure they are used to it.

How I know there's an impending quake is our background noise becomes a roar as if there was earthmoving equipment in the neighborhood, you have to shout at each other to hear standing in the yard. It's the sound rock grinding against rock.

Fractoluminescence. When the green lights are flashing and bouncing around, the pressure fractured granite.

The mountains are booming and the military is not flying.

When these things happen, there will be a substantial quake within 200 miles or a smaller quake locally.

The ground moves all the time, get used to it.

We're in the ring of fire - lots of activity from volcanoes to earthquakes. I think we hear more about them due to news circling the world in seconds. I recall the Alaskan earthquake:

Lasting four minutes and thirty-eight seconds, the magnitude 9.2 megathrust earthquake remains the most powerful earthquake recorded in North American history, and the second most powerful earthquake recorded in world history.

Did you read that? 9.2 and we lived in the San Francisco Bay Area at the time. I remember seeing the coffee table slide across the room. That was almost 60 years ago, so we're due for another one. I don't live in the Bay Area any longer. Also was in the Loma Prieta earthquake that hit the Santa Cruz area (happened during the World Series). I'd rather be in an earthquake than a tornado or hurricane.

To put the Fairbanks, AK earthquake into perspective, the epicenter was 2,136 miles from San Francisco. That's how powerful it was. No damage to our home.

soooo . . . just saw this thread.

Both dogs have been wonky, yesterday and today. Hiding in my closet, under the bed and so on. They don't want to eat, either.

Nothing different around here other than Thanksgiving.

My Labs did the same thing right before the big Calexico quake.

fwiw, most of Phoenix sits on Quaternary fill. My home sits on Precambrian granite, so when we get quakes I always feel it.

Makes you go hmmmm. 1dunno1

Why the livestock are circling:

Another possible cause could be parasites.

My dogs act strangely a lot more often than there is an earthquake, so I don't know how I could ever make use of them for early warning. I will just have to hold out for strange cravings or "ear tones," I guess.
