Earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves.
Tectonic earthquakes will occur anywhere within the earth where there is sufficient stored elastic strain energy to drive fracture propagation along a fault plane.
There are three main types of fault that may cause an earthquake: normal, reverse (thrust) and strike-slip. Normal and reverse faulting are examples of dip-slip, where the displacement along the fault is in the direction of dip and movement on them involves a vertical component. Normal faults occur mainly in areas where the crust is being extended such as a divergent boundary. Reverse faults occur in areas where the crust is being shortened such as at a convergent boundary. Strike-slip faults are steep structures where the two sides of the fault slip horizontally past each other ; transform boundaries are a particular type of strike-slip fault. Many earthquakes are caused by movement on faults that have components of both dip-slip and strike-slip; this is known as oblique slip.
Earthquakes often occur in volcanic regions and are caused there, both by tectonic faults and the movement of magma in volcanoes. Such earthquakes can serve as an early warning of volcanic eruptions.

What must be passed for earthquakes to occur?
Earthquakes occur when there is a sudden release of energy in the Earth's crust. This release of energy is typically caused by the movement of tectonic plates along faults. The stress built up along the fault lines is released as seismic waves, resulting in an earthquake.
What type of earthquakes occur farther inland than other earthquakes?
Intraplate earthquakes occur farther inland than other earthquakes. These earthquakes occur within a tectonic plate, away from plate boundaries where most earthquakes typically occur. Intraplate earthquakes can be caused by ancient faults or stress within the plate itself.
What geologic events occur at transform boundries?
Earthquakes
Do Earthquakes occur only once or twice a year?
The frequency of earthquakes depends on the location. in Japan, earthquakes occur 3 times a month, and in the Sahara in Africa they occur once in five years..
Do earthquakes occur in groups?
no
Earthquakes can occur when the what of rocks is passed?
Earthquakes can occur when the stress limit of rocks is passed, causing them to break and release built-up energy in the form of seismic waves that shake the Earth's surface.
What are the smaller earthquakes that occur following the main earthquake?
These are known as aftershocks.
What biome do earthquakes occur in?
The lithosphere is where earthquakes occur.

What plate boundary do earthquakes occur?
Earthquakes occur at all plate boundaries.
Do volcanoes occur in oceans and earthquakes occur on land?
Earthquakes and volcanoes both occur in land and ocean. =)
Do earthquakes occur as earth's plates collide?
Yes that is generally where most earthquakes occur
What type of earthquakes occur farther inland than other earthquakes?
Intraplate earthquakes occur farther inland than other earthquakes. These earthquakes occur within a tectonic plate, away from plate boundaries where most earthquakes typically occur. Intraplate earthquakes can be caused by ancient faults or stress within the plate itself.
What geologic events occur at transform boundries?
Earthquakes
What occur along a fault?
Earthquakes occur along a fault. Near the San Andreas fault lots of earthquakes occur.
Where on earth do earthquakes occur?
Most earthquakes occur at or near the boundaries between tectonic plates.
Do most earthquakes occur around earthquake valley?
Please more specific, as earthquakes occur worldwide.
