The most earthquake damage tends to occur at the epicentre, which is the point on the surface above the hypocentre, or focus, of an earthquake. It is the point in the Earth's crust where the rock first breaks.However, many earthquakes do not actually break the earth's surface. It has been found that the most damage in an earthquake tends to result from the secondary effects, especially the movement of seismic waves away from the epicenter. These secondary effects include landslides, liquefaction, fissuring and aftershocks.
A magnitude 6.0 earthquake has the potential to cause damage, depending on various factors such as the depth, distance from populated areas, and the type of infrastructure in the affected region. Generally, it can result in moderate to significant damage to buildings and structures, particularly if they are not built to withstand seismic activity. The impacts can range from cracked walls and broken windows to partial collapses and damage to bridges and roads.
The earthquake was so destructive for a number of reasons:The earthquake occurred at shallow depth - this means that the seismic waves have to travel a smaller distance through the earth to reach the surface so maintain more of their energy in particular this meant that the surface waves (which cause the vast majority of the damage during an earthquake ans which are the most rapidly attenuated and and have significant reductions in amplitude as the depth of the earthquakes focus increases) produced by the earthquake maintained a large amount of their energy maximising the damage they cause.The earthquake occurred in close proximity to a populated area. This again means that there is very little attenuation of the seismic waves (i.e they still have most of their energy and so are more destructive when they arrive).The buildings in Port-au-Prince and other areas of Haiti were in very poor condition in general and were not designed or constructed to be earthquake resistant.Please see the related question for further information.
They come in all magnitudes from can't-be-felt to knock-down-everything standing for 500 miles. They can happen almost anywhere (swamps and sandbars seem safe), but most (85%) happen on plate boundaries.
well te earthquake caused the tsunami to hit so the earthquake did the most damage
seismic waves
The seismic scale that measures the intensity of earthquake damage is called the Mercalli intensity scale. This scale measures the effect an earthquake has on people and surroundings.
because it caused more damage
seismic waves :)
The L- Wave or the Love and Rayleigh waves (collectively known as surface waves) cause most of the damage during an earthquake.
The surface waves (of which their are two types, Rayleigh and Love waves) cause the most damage during an earthquake.

Risk
Seismic waves are produced by earthquakes, rather than the cause of them! The most damaging seismic waves are the surface waves of which there are two types. Love waves and Rayleigh waves. For more information, please see the related links and question.
magnitudea measure of the amount of the energy released by earthquake . earthquake is measure through Ricthter scale that measure the magnitude of seismic waves that it has
The movement of seismic waves
Surface waves (e.g. Rayleigh waves, Love waves) that produce vertical motion of the ground surface produce the most damage during an earthquake.
