Within minutes of the rattling of Melbourne in yesterday’s quake, my Victorian friends reported changes in their animal behavior.
Written by a friend Social media Her dog Harvey standing in the hallway and barking for 5 minutes Previous The earth has moved. A colleague reported that the TV reception was blurry, but when he went out to check the air, he noticed “an unusual and impressive lack of bird calls” before he felt the quake. ..
My friend, Henry, disappeared mysteriously before the quake, but returned home safely hours later. Conversely, her fear of storms, Rough Collie’s Angie, is reportedly “completely chilled” before, during, and after the quake.
Earthquakes are anxious, frightening, and potentially deadly. 1989 Newcastle earthquake 13 dead, 160 injured.. It can really save lives if our animal companions can pay attention to us when such an event is likely to occur. But can they really do it? Let’s look at the evidence.
Academic literature provides dozens of case reports Companion animal, livestock, Wild animals And even insect I behaved strangely before the earthquake.
However, review Of the 180 publications reporting 700 records of abnormal or abnormal animal behavior prior to 160 earthquakes, evidence to correlate these behaviors with subsequent earthquakes was found to be weak.
Most of the reports are anecdotal and were produced after the earthquake, making them vulnerable to “recall bias.” Simply put, people may be more likely to interpret animal behavior as strange, especially in the light of memorable or traumatic events.
To prove that anomalous animal behavior can predict earthquakes, scientists have moved animals under controlled environmental conditions long enough to observe pre-, mid-, and post-earthquake behavior. It needs to be observed for a long time.You also need to look at the animals to be sure they actually behave strangely before the earthquake No Strange behavior when there it’s not An imminent earthquake.
Sadly, the evidence isn’t close enough to satisfy this. However, the authors of the review found that the expected “predictive” behavior of animals was “Foreshock“— A small earthquake that precedes a major earthquake event.
In this case, what people interpret as an animal’s ability to “predict” an earthquake may actually be a reaction to vibration or sound from an earthquake that is too weak for us humans to detect.
This is not surprising given that animals are often superior to us in terms of sensory perception, such as: odor..And almost 60% of the abnormal animal behavior associated with earthquakes 5 minutes before the earthquake..
Fear and flight
The fear, anxiety, and distress caused by the foreshock may explain why animals exhibit behaviors such as vocalization (like howling dog Harvey) and fleeing to places they feel safe (like the disappearing cat Henry). Maybe.
But of course, Harvey and Henry could have behaved this way for reasons purely unrelated to the earthquake, and the timing was purely coincidental. There are many reasons why a dog howls (courier opens the main gate) or a cat goes missing (cats can be heard). Loud sound And hide under the bed), but we tend to establish connections only when we notice the same stimulus.
What we know is that animals can be seriously affected by an earthquake, such as injury, movement, or reduced access to food or water. Thousands of animals, together 185 peopleDied in the 2011 Christchurch earthquake, more animals lost their homes due to property damage.
Yesterday’s quake is an important reminder for people with friends animal Include them in your emergency plan. Dogs and cats should be identified by a collar, tagged and microchiped. Also, don’t forget to update your contact details if you move home or change your phone number. That way, it’s easier to meet again.
