Can a Big Enough Earthquake Be Felt Around the World?

Dozens of earthquakes occur every day in the world, but most of them are just It is felt in certain areas.

Alright, a big enough earthquake Can it be felt all over the world?

How wide can large earthquakes expand?

Earthquakes occur as a result of fractures in the earth’s crust with seismic waves is spreading. These waves lose their energy as they spread towards the earth’s surface. However, some very large earthquakes can be felt even kilometers away.

For example, what happened in Chile in 1960 9.5 magnitude Valdivia Earthquake, It is known as the largest earthquake in history and was felt not only in South America but even in Asia.

But this was not an event that everyone around the world felt. The seismic waves were quite strong, but still will reach every corner of the world It was not as effective.

Sumatra Earthquake

magnitude 9.1 in 2004 In the Sumatra Earthquake The ground was displaced vertically by at least 1 cm everywhere in the world. But such a change was not perceived by humans because it occurred within seconds, and as humans we We are not sensitive enough to feel.

The best way to understand the energy released during earthquakes is to study how seismic waves move.

These waves spread throughout the earth’s crust and reach people. However, the energy of these waves is not the same at every point. in different parts of the world structure of the earth’s crust, This can affect the speed and intensity of the waves.

In fact, today, even if there is no earthquake affecting the whole world, earthquakes all over the world seismometers It can record even the smallest tremors.

at the end of the world a big earthquake, Although they are not felt by people living on the other end, the presence of seismic waves can be determined with certainty.

In this way, scientists can quickly detect the source and strength of the earthquake. In fact, our planet they keep their pulse We can also say.

So, is it possible for everyone to feel an earthquake at the same time?

Theoretically, a mega earthquake caused by massive movements in the core and mantle of our planet, It can spread over a very wide area on the surface.

However, it is quite difficult for these waves to affect the whole world at the same time. It’s a difficult scenario. Instead, while they produce major effects in certain parts of the world, they can only be detected with sensitive seismometers in remote areas.

In other words, even if an earthquake large enough to be felt by everyone is theoretically possible, it is not possible in practice. It’s quite unlikely.
