 [[Destructive Plate Margin]]s typically occur between a [[Continental Plate|continental plate]] and [[Oceanic Plate|oceanic plate]]. Upon collision, the denser [[Oceanic Plate|oceanic plate]] is forced under the lighter [[Continental Plate|continental plate]] in a process known as [[Subduction|subduction]]. There is a huge build-up of [[friction]] between the two plates as this happens, until the [[force]] becomes so great the plates no longer move.  As the plates are released and jerk away from each other they release shock waves that that spread from the [[Focus|focus]] deep in the [[mantle]] where the plates are coming together. The shock waves are then felt on the surface of the [[crust]] and they are most strongly felt at the [[Epicentre]] which is the point directly above the [[focus]]. This is an '''earthquake'''.

 At [[Constructive Plate Margin]]s the plates are moving away from each other and this causes cracks in the plates as they move. Tension then builds in these cracks and is eventually released in the form of shock waves that can be felt of the surface of the earth at the [[crust]] as an '''earthquake'''.

 Earthquakes come in a variety of strengths therefore there is a scale that shows you how strong each earthquake is and how much damage it is likely to do. This is called the '''moment magnitude scale'''. This scale measures the amount of energy released by an earthquake and is measured logarithmically. This means that a magnitude 2 earthquake is ten times stronger than a magnitude 1 earthquake. Earthquakes below magnitude 6 only cause slight damage to buildings and earthquakes magnitude 7 and above can cause high levels of damage and large loss of life.
