WebbWhen the force of movement finally overcomes the friction, sections of the crust suddenly break or become displaced, releasing the pent-up pressure in the form of seismic waves. This is a naturally occurring earthquake, sometimes referred to as a tectonic earthquake.

"Webb11 nov. 2024 · Many earthquakes follow a non-swarm pattern known as a mainshock-aftershock sequence. In its simplest form, this means that the largest earthquake occurs first in this sequence, followed by a series of smaller shocks, decaying over a time period ranging from weeks to decades.
