An earthquake occurs when the edges of two tectonic plates get stuck on each other. Stress builds, like the stress you get when you hold onto a friends hand and pul away without letting go. When the stress is released the two tectonic plates do one of two things. Either they will push up against each other (known as a thrust fault), pull away from each other (known as a normal fault) or more commonly slide along each other (known as a slip or slide fault). The stress takes the form of seismic waves and they both contribute to thee shaking of the ground.
The 1906 San Francisco earthquake occurred at a transform plate boundary, where two plates slide past one another.
A seismometer, also known as a seismograph, is the instrument that produces patterns indicating earthquakes. It measures the ground motions caused by seismic waves and records them as seismic waves on a seismogram. These patterns help seismologists analyze the earthquake's magnitude, depth, and location.
It is movement of land beneath the sea, often it is a land slide that displaces water and produces the wave.
Seismic waves from a 6.1 magnitude earthquake are significantly larger than those from a 3.1 magnitude earthquake. The Richter scale is logarithmic, meaning each whole number increase represents a tenfold increase in measured amplitude. Therefore, a 6.1 magnitude earthquake produces waves with approximately 31.6 times more energy than a 3.1 magnitude earthquake.
The increase in wave amplitude during an earthquake can vary significantly depending on the earthquake's magnitude and depth. For instance, each whole number increase on the Richter scale corresponds to approximately a tenfold increase in wave amplitude. This means that a magnitude 6 earthquake produces waves with amplitudes ten times greater than those of a magnitude 5 earthquake. The actual amplitude increase observed can also be influenced by geological factors and the distance from the epicenter.

The waves of energy that an earthquake produces are called seismic waves. There are two main types: body waves, which travel through the Earth's interior, and surface waves, which travel along the Earth's surface.
It is movement of land beneath the sea, often it is a land slide that displaces water and produces the wave.
a magnitude 7.2 earthquake produces 10 times more ground motion than a magnitude 6.2 earthquake, but it releases about 32 times more energy. The energy release best indicates the destructive power of an earthquake.
It suddenly slips when the stress across it becomes too high, which produces a sudden series of shockwaves that radiate in all directions from the fault through the surrounding rock. The earthquake you feel happens when these shockwaves reach the surface.
An earthquake of magnitude 7.0 produces 1000 times more ground motion than an earthquake of magnitude 4.0. Magnitude is a logarithmic scale, with each whole number increase representing 10 times more amplitude and approximately 31.6 times more energy released.
The intensity of an earthquake refers to the amount of shaking and damage felt at the Earth's surface, while the magnitude is a measure of the energy released at the earthquake's source. A higher magnitude earthquake will generally result in higher intensity shaking and potential damage, but factors like depth and distance from the epicenter also influence intensity.
Each unit increase in earthquake magnitude represents a tenfold increase in amplitude of ground motion. For example, a magnitude 6 earthquake produces 10 times larger ground motion than a magnitude 5 earthquake. This logarithmic scale is known as the Richter scale.
Earthquake energy is released at the hypocenter, which is the exact location within the Earth's crust where the seismic rupture begins. This release of energy produces seismic waves that propagate outward in all directions, causing the ground shaking and damage associated with earthquakes.
The focus is a feature of an earthquake; it is the point underground where the earthquake originates, directly beneath the epicenter. A hot spot is an area away from a plate boundary that produces volcanic activity, most likely due to a rising plume of extra hot material in the mantle.
