The omen before the earthquake After seeing the Tangshan earthquake, I began to like asking this question.

Birds are usually very sensitive to environmental changes, among which pigeons are more capable than other birds. According to the research of seismologists in China, when the Richter scale is above 3, pigeons within 50 kilometers of the earthquake will move to other places within 24 hours. Besides pigeons, birds such as crows, canaries and parrots are also extremely sensitive to earthquakes.

Pigeons or birds suddenly disappeared.

The birds in the cage bumped around to get rid of the cage.

1995 before the Kobe earthquake, the fishing amount in the nearby waters suddenly increased, and even deep-sea fish groups swam to shallow waters.

Strange fish schools or deep-sea fish schools appear offshore.

Before and after the earthquake, the catch in the nearby waters increased by 2~ 10 times.

Freshwater fish:

Earthquakes usually occur when carp jump out of the water or behave rudely.

Earthquakes usually occur when catfish behave rudely.

Snakes hibernating underground will sense the changes of electromagnetic waves in the crust and carbon dioxide, and even climb to the ground to take refuge in winter.

Hibernating snakes will climb to the ground.

The snake appeared in the wrong place (street, expressway, etc.). ).

1976 a few hours before the Tangshan earthquake, hundreds of hibernating frogs were witnessed crawling to the ground.

The hibernating frog climbed to the ground.

Thousands of frogs migrate on a large scale.

Abnormal behavior of mammals:

The dog ran around excitedly.

The tame dog became fierce.

Cats fidget or climb trees.

Cats make rather annoying noises continuously or continuously.

The mouse suddenly disappeared.

The mouse ran around at a loss.

It's easier to see the mice on the mousetrap than usual.

Changes of groundwater and well water:

The smaller the scale, the shorter the time of water anomaly. For example, an earthquake of magnitude 7 or above occurred about a year ago, and an earthquake of magnitude 3 or below occurred a few months ago.

The amount of water increases,

Water quantity reduction

Floating oil drop

Produce bubbles

Produce a vortex

Become turbid

Give off an unpleasant smell

Jet water column

Earthquake sound:

thunder

The wind (the roar of the bull elephant)

Explosion (explosion of large shells)

Mechanical sound

Sawing sound

Tearing sound

The characteristics of seismic clouds remain unchanged for a long time (the following brackets are wrong, not seismic clouds)

Broadband (if it goes away over time, it is likely to be aircraft cloud)

Fish-scale cirrocumulus (not only changing shape)

The fan-shaped cloud can clearly see the waist position of the fan, which is where the earthquake happened. (unable to determine waist circumference)

Tornado-like clouds (dispersed in a short time)

Other symptoms:

Anxiety and irritability

suffer from a long drought

Rainy and rainy

It takes at least 10 minutes to calm down (telepathy) when you know that an earthquake may happen at any time, or when you think about its power.

Poultry does not roll.

Hot spring water suddenly disappeared overnight, sometimes accompanied by sulfur smell.

electrical accident

A large area of plants withered.

The plants are too lush.

Low fog

The lawn swelled, dropped for a few days and swelled again. ...

Strange things happened, eg water suddenly gushed out of the ground.

Flowers germinate, blossom and bear fruit in the wrong season.
