Earthquakes are a sudden release of energy in the Earth's crust.
Earthquakes most commonly occur at the boundaries of tectonic plates where stresses accumulate in the earth's crust over time, causing energy to be stored in the form of elastic strain (like that in a compressed spring).
Ultimately this stress will exceed the shear strength of the crust in the fault or boundary zone causing a sudden brittle failure or rupture.
This in turn causes movement and a sudden release of the stored elastic strain energy in the form of seismic waves (as well as heat) causing an earthquake.

An Earthquake forms by 2 plates moving.
For Example:
The Christchurch Earthquake started when
The Indo-Australian and the Indo-Pacific plates
Over-lapped each other. Christchuarch is on the
"Fault Line" of the plates so that is why Christchurch had
The Earthquake..... So this helps!! )

Where are earthquakes mosty likely to originate?
where the fault is at or the epicenter which is not where the earthquake starts it is the focus where the earthquake starts
What is the difference between an earthquake's fucus and epicenter?
An earthquake's focus is the point within the earth where the earthquake starts. The epicenter is the point on earth directly above the focus.
The place inside Earth where an earthquake starts in the what?
The point of origin of an earthquake is called its focus. The point on the surface directly above the focus is called the epicenter
How much pp does earthquake have?
Earthquake starts with 10pp, and can have a maximum of 16pp (with items that boost PP amount, like PP up and PP Max).
What is directly below the epicenter of an earthquake?
Directly below is the focus. The focus is the place where the earthquake originally starts. From there, shock waves move in all directions.
focus?
the point within earth where the earthquake starts
Where are earthquakes mosty likely to originate?

Where does a shockwave in an earthquake start?
It starts at the focus or hypocentre of the earthquake.
How do you know when the earthquake starts?
The ground starts shaking.
Where earthquake begins?
it starts in the focus
When is 2012 earthquake starts?
There will, no doubt, be an earthquake in 2012 but no one can know when or where it will happen, or how severe it will be.
What is the name above an earthquake?
The point at which the earthquake starts - is the Epicentre.
What is a earthquake fact that starts with Q?

AWSOME
Where is the most damage done when an earthquake occurs?
The surface that is right above the epicenter of the earthquake,or the place that is right above where the earthquake starts.
What earthquake word starts with the letter j?

How are earthquakes different from mountains?
Because a earthquake isn't a mountain.. A earthquake starts to happen underground then is on top.
