Seismic waves do not end at an earthquake's center; rather they continue to propagate through the Earth in all directions from the initial point of rupture. The seismic waves can be recorded by seismometers located around the world, providing valuable information about the earthquake's location, magnitude, and source mechanism.
The name given to the point where an earthquake begins is the "focus" or "hypocenter." This is the location within the Earth where the seismic energy is first released, leading to the generation of seismic waves that cause shaking felt at the surface.
The underground origin of an earthquake is called the hypocenter or focus. This is the point within the Earth's crust where the seismic energy is released, leading to the generation of seismic waves that cause the ground shaking we feel at the surface.
Energy released during an earthquake creates seismic waves that travel through the Earth's crust, causing the ground to shake. This energy can also lead to the displacement of rock layers, fractures in the Earth's surface, and the generation of secondary hazards such as landslides and tsunamis.
Primary waves (P-waves) were discovered by the Croatian seismologist Andrija Mohorovičić in 1909. P-waves are the fastest seismic waves that travel through the Earth's interior and are the first to be detected during an earthquake.
Natural selection
the mechanism failed when the earthquake struck. or the mechanism is essential because it provides humans with clean and breathable air in a city full of smog
Numel does not naturally learn Earthquake in its movepool. However, it can learn Earthquake through TM26 in Pokémon games, starting from Generation III.
A thunderstorm would never result from an earthquake. Earthquakes can cause fires by breaking gas lines and electrical wires, but there is no mechanism by which an earthquake could cause a thunderstorm.

The Antikythera mechanism, also known as the "wedge," was discovered in 1901 in an ancient shipwreck off the coast of the Greek island of Antikythera.
The animation on this page shows the main concepts that define a seismic event, as well as some of the consequent effects.

Gravitational contraction was an important energy generation mechanism for the Sun during its early formation stage when it was collapsing from a cloud of gas and dust. As the Sun contracted under its own gravity, potential energy was converted into thermal energy, causing the core temperature to rise and initiate nuclear fusion. Today, the primary energy generation mechanism in the Sun is nuclear fusion in its core.
When an earthquake is sourced, the coulomb stresses that originate from the source (due to the P-wave) are bounded by two perpendicular planes, which make up the 2 planes in an earthquake focal mechanism. Both are mathematically equivalent. Thus, without independent knowledge of which plane sourced the earthquake, either could be the "fault". Therefore, the axillary plane represents the mathematical equivalent to the source of the earthquake and is represented in earthquake focal mechanisms for a variety of reasons (helps visualize the style of faulting, disambiguity, completeness, etc.) It is extremely common for seismologists to calculate the focal mechanism without knowing which plane is the fault and which is the auxillary plane
The point underground where an earthquake originates is known as the hypocenter or the focus. This is the specific location within the Earth's crust where the seismic energy is released, leading to the generation of seismic waves that cause the earthquake.
