Dozens of earthquakes happen around the world every day, but most of them are just It is felt in certain areas.
Agree, a big enough earthquake Is it felt all over the world?
How wide can large earthquakes spread?
Earthquakes occur due to fractures in the Earth’s crust with seismic waves spreads. These waves lose their energy as they spread to the Earth’s surface. However, some very large earthquakes can be felt even miles away.
For example, what happened in Chile in 1960 Valdivia earthquake with a magnitude of 9.5, 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 was felt by everyone around the world. The seismic waves were quite strong, but still will reach every corner of the world It wasn’t that effective.
magnitude 9.1 in 2004 During the earthquake in Sumatra Everywhere in the world the ground has moved vertically at least 1 cm. But such a change was not perceived by humans because it happened in a matter of seconds, and we as humans 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 across 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 that affects the entire world, there are earthquakes all over the world seismometers It can register even the smallest vibrations.
at the end of the world a great earthquake, Although they are not felt by people living on the other side, the presence of seismic waves can be determined with certainty.
This way, scientists can quickly detect the source and strength of the earthquake. In fact, our planet they take the pulse We can say too.
So is it possible for everyone to feel an earthquake at the same time?
Theoretically, a mega-earthquake, caused by enormous movements in our planet’s core and mantle, would It can spread over a very large area on the surface.
However, it is quite difficult for these waves to affect the entire world at the same time. It’s a difficult scenario. Although they have major impacts in certain parts of the world, they can only be detected in remote areas with sensitive seismometers.
In other words, even though an earthquake big enough to be felt by everyone is theoretically possible, in practice it is not. It’s quite unlikely.
