The point underground where the rock fractures (moves).
Question
The point underground where the rock fractures (moves).
Solution
The point underground where the rock fractures or moves is known as the focus or hypocenter of an earthquake. This is the exact point within the earth where seismic waves are initiated. Here are the steps to understand this:
-
The Earth's crust is divided into large pieces called tectonic plates. These plates are constantly moving, albeit very slowly.
-
Sometimes, these plates get stuck while trying to slide past each other. When this happens, stress builds up at the point where the plates are stuck.
-
Eventually, the stress becomes too much and the rock fractures or moves. This point of initial movement is the focus of the earthquake.
-
The seismic waves then radiate out from this focus, causing the shaking and other earthquake effects we feel on the surface.
-
The point directly above the focus, on the surface of the Earth, is known as the epicenter of the earthquake. This is often the area that experiences the most severe effects of the earthquake.
