Does nature warn when a big earthquake is coming? Do animals hear this warning when we don’t?
This post presents different possible earthquake precursors or reading signs before an impending strong quake.
1. EARTHQUAKE SIGNS: GROUND OR WATER
Skyquakes or mysterious booming noises are typical ground precursors. They may occur several day before a large quake. Before the Christchurch earthquake, the 1812 New Madrid earthquake and the Sichuan Sichuan earthquake, unusual silt in usually clear streams, and rivers flowing backwards were reported as shown in this video:
2. EARTHQUAKE SIGNS: AIR, SKY AND CLOUDS
There are typical earthquake qeathers with strange cloud formations, very still and warm weather. Rainbow clouds are often reported before quakes as featured in this video 20 minutes before the Sichuan earthquake:
This interesting video discusses a scientific paper about atmospheric changes related to earthquakes:
3. EARTHQUAKE SIGNS: ANIMAL BEHAVIOUR
If your pet goes berserk at an inconvenient time, be inclined to humour it. It might save your life!
Thousands of Frogs Appear on City Streets Right Before China Earthquake
And as show by the last few weeks, underwater creatures beaching such as oarfish and whales may be a great sign for impedent large quakes.
4. EARTHQUAKE SIGNS: ELECTRONIC
The most typical electronic precursor are TV interference, unusual and sometimes unique the night before the quake.
5. EARTHQUAKE SIGNS: EARTHQUAKE LIGHTS
This last video presents earthquake lights over Christchurch, just before the quake… Amazing. And here another article about these mystic lights.
6. EARTHQUAKE SIGNS: OTHER PRECURSORS
The most common reported “other” precursor was a feeling of pressure, sometimes manifested as headache (also felt before aftershocks). These ranged from those usually classified as “psychic” to physiological symptoms. Other people reported intense feelings of itchiness before the earthquake.
So is it possible to predict earthquakes?
Is it possible to predict earthquakes? In spite of sporadic successes the answer in general is “no”. The most spectacular success was HaiCheng, China 1975. Researchers used several converging lines of evidence to persuade authorities to evacuate the entire city of one million people. The next day a disastrous earthquake struck which would have killed tens of thousands. However, the same techniques next year in the city of TangShan led to evacuation and no earthquake in the predicted time period. No general earthquake precursor exist!
