What is Replica definition/concept/elaboration

Some words have a meaning in colloquial language and, at the same time, another meaning in scientific terminology. This is what happens with the term replica. In an ordinary conversation, the reply refers to the contestation of a speech, which is why we speak of the right of reply. On the other hand, in seismology, where we will focus, the replica is a seismic movement produced by another previous seismic movement.

How does a replica happen?

A first seismic movement generates a terrain change and this change in structure produces, in turn, a new movement, the replica. It should be noted that the replica is not necessarily smaller than the previous earthquake , in fact, on certain occasions, the strength of the replica may be greater.

Earthquakes and aftershocks

The place on the earth’s surface where an earthquake starts is known as the epicenter. At this point it starts to release energy stored for a long time and finally this energy overflows and produces a vertical and horizontal displacement on the ground. These movements sometimes affect the surface of the seabed, and when this happens, a tsunami occurs. Normally, earthquake aftershocks are located within the rupture area.

The origin of earthquakes and seismology

An earthquake is a vibration of the earth. This occurs because of the release of energy at a certain point. The energy released is transmitted in the form of waves and, in this way, the rocks vibrate and the ground cracks. The starting site is called the hypocenter or focus, and the epicenter is the area that lies on the surface of this focus.

Seismology is the scientific discipline that studies this type of phenomenon

According to the theories used by seismologists, earthquakes are formed by the elastic rebound that occurs in an area, the fault. Thus, the tectonic forces of the earth’s interior exert a force on these faults that end up breaking on its surface. This break creates a landslide. Faults are classified according to their movement, which can be vertical, horizons or oblique.

Currently, seismologists are trying to create theoretical prediction models so that they can take preventive measures in order to minimize the impact of earthquakes. Because of this, seismologists need to collaborate with other professionals, such as architects, geologists, geophysicists and civil engineers.
