Will the epicenter shift? Will the epicenter move

In a **, the epicenter will not be offset.

However, if it happens again** the epicenter has the potential to change.

The epicenter means that it is the starting point of the rupture.

Wenchuan** is caused by the rapid uplift of the Qinghai-Tibet Plateau caused by the subduction of the Indian plate to the Asian plate, and the depth of the epicenter is 10 km to 20 km, and the duration is long, so the damage is huge.

But as the plates collide, the stress point may be different each time, so in the aftershocks after Wenchuan**, the changes that occur at the epicenter.

This is a shallow source (near the surface) structure.

Structure: The reason for the occurrence of structure is that the underground rock layer is subjected to the action of in-situ stress, when the in-situ stress is too large, the rock layer can not bear it, it will occur suddenly, rapid rupture or dislocation, when the rock layer rupture or dislocation, it will excite a kind of ground wave that spreads to the surrounding area, and when the wave reaches the surface, it will cause the ground to shake. 85% of the world's 90% of the world's disasters and all of the world's major disasters are tectonic.

The place where ** occurs underground is called the "epicenter", and the ground directly opposite the epicenter is called the "epicenter". The area near the epicenter where the vibration is greatest and generally the most destructive is also called the "extreme earthquake zone". The vertical distance from the epicenter to the hypocenter is called the "hypocenter depth".

Usually, according to the depth of the hypocenter, it is divided into shallow source (hypocenter depth less than 70 km), medium source (hypocenter depth of 70-300 km) and deep source (hypocenter depth greater than 300 km). More than 95 of the world's ** are shallow sources**, and the depth of the epicenter is concentrated around 5-20 km.

The epicenter is the birthplace of **, and the birthplace will not move.

It won't be offset, so don't worry.

The epicenter, also known as the epicenter location, is the vertical projection of the hypocenter on the horizontal plane of the earth's surface. In fact, the epicenter is not a point, but an area.

The epicenter also has a certain range, which is called the epicenter area, and the epicenter area is the area with the strongest destruction. The ground distance from the epicenter to any ** station (station) is called the epicenter distance. There are generally two ways to determine the location of the epicenter:

The first is the post-earthquake investigation, which determines the most devastation as the epicenter, which is called the macroscopic epicenter; The other is the projection of the earthquake rock peiyuan on the ground according to the ** instrument, which is called the microscopic epicenter. Due to the influence of factors such as the physical state of the hypocenter area and the geological conditions of the ** area, the location with the greatest destructive power on the ground is not necessarily located directly above the epicenter, so the macroscopic epicenter does not necessarily coincide with the microscopic epicenter.

The hypocenter is in a vertical projection on the ground. **The distance from the observation point to the epicenter is called the epicenter distance, and the distance from the epicenter is less than 100 kilometers is called a local earthquake; At 100 1000 km is called a near-earthquake; More than 1,000 kilometers are called teleshocks. As the distance from the epicenter increases, the impact of ** decreases.
