Why does earthquake occur only in the central part of the land?

Why does earthquake occur only in the central part of the land?

Ninety percent of the earth’s tremors occur on the borders of continents.

Researchers explain that the continents keep moving and their edges rub against each other and this is the main reason for earthquakes to occur on the borders of the different continents.

But, nearly ten percent of the earthquakes occur in the central part of the earth.

What is the reason for the earthquakes to occur only in the central part of the earth?

Researchers are at a loss to explain the reason for earthquakes occurring only in the central part of the earth.

“Embarrassment causing adopted child”

In the book published by the American geological department, Dr. Seth Stein of Illinois University has not only stated that researchers do not know the reason for the occurrence of earthquakes only in the central part of the earth, but also refers to such quakes as “embarrassment causing adopted child”.

When the rocky plates below the earth rise upwards, earthquakes occur only in the central part of the land surface.

Why did North America experience earthquakes in the central part of its land surface?

Till this day, it has not been explained why earthquakes occurred in New Madrid situated in the central part of North America during December 1811 and January 1812.

Researchers believe that, the continents are moving and their edges rub against each other and this is the reason for earthquakes to occur.

But, New Madrid is situated in the central part of North America . During the earthquake, the land surface of the city of Tennessee in this region was seen to rise to a length of fifty kilometers and a breadth of twenty three kilometers.

The land surface in the south western part of the city of Missouri, north western part of the city of Tennessee and the south western part of the city of Kentucky had risen up to thirty feet. This has resulted in a permanent change in the path of the river Mississippi .

Why the central part of China alone is experiencing earthquakes?

Researchers have discovered the fossils of living things that lived fifty crores of years ago on Mount Jinbo , situated in the district of Sichuan in central China .

Based on this they also state that, fifty crores of years ago this region was below the sea.
While the land rose above sea level, the living things that were buried in the land slide are only seen as fossils on Mount Jinbo now.
Hence, the reason for the presence of fossils on the mountain and the occurrence of earthquakes is the rising of the land surface above sea level from below the sea.
This proves beyond any doubt that earthquakes occur due to the rising of the land surface.
