Birds flying about near the earthquake, creatures that come out of the pit. Did they really know earthquakes in advance? Why ? Is this possible?
People think that some animals can predict earthquakes.
Before explaining this, you need to know when earthquakes happen and what is an earthquake?
This article is based on Quora's Why do birds fly from the tree during earthquake ?
I read the question so wrote this article.
MASES - Myanmar Astronomy & Science Enthusiasts Society's post is also based on this post.

What is an earthquake and how does it happen?
Earthquake is the vibration of the earth's surface when two earth's crusts collide.
The earth's surface is composed of four layers called inner core, outer core, mantle, and crust.
The two outermost layers are the crust and the mantle.
In these two layer, the earth's solid (called Tectonic Plates) are included in various parts.
These tectonic plates are always moving and bumping into each other, one intruding one on top of the other, and so on.
When two moving tectonic plates collide, they cannot move forward.
But even if they stop, the kinetic energy that causes the Earth's tectonic plates to move won't stop.
As the energy slowly accumulates near the point of collision, it becomes a huge wave from the push.
Just like the waves when something falls into water, the energy accumulates at the point of collision and these huge waves
can shake everything up, causing the Tectonic Plates to shake and vibrate.
That is called an earthquake.
Why do birds fly before an earthquake ?
The waves that are kicked around from the accumulation of energy are called seismic waves.
When those waves come out of the earth's underground, the small-sized waves are far away and cannot cause damage to things on the earth's surface.
The P-Wave, the fastest wave arrived first onto the earth's surface.
Some animals, such as birds, may feel this P P-Wave and respond by rising and flying.
But this is not yet accepted by scientists and is only the most likely conclusion.
Therefore, it cannot be said that it is true that the animals felt the earthquake.
So no one can predict the earthquake?
It is true that earthquakes cannot be accurately predicted to this day.
But when other things happen, the possibility of an earthquake is calculated and the result was published.
For example, a volcanic eruption. There is a connection between volcanic eruptions and earthquakes.
When a volcano erupts, its vibration causes earthquakes, and when earthquakes occur, it is usually a volcanic eruption.
Small earthquakes can also be precursors to a large earthquake.
Small vibrations occur when tectonic plates move and collide.
Soon kinetic energy will accumulate and it is predicted that it will become a major earthquake.
However, since the place where the earthquake occurred is in the far interior, it is possible that
when it reaches the surface of the earth, it will weaken and become a small earthquake.
In addition, when earthquakes occur around fault lines, experts who monitor these areas measure the backs of the faults and
calculate the probability of another earthquake and publish them.
Earthquakes are unpredictable, but when they do happen, you should make preparations and read and remember emergency actions, safety tips.
Only then can danger to life be avoided.
