It is called an aftershock.
A small earthquake that happens after a larger one is called an aftershock. Aftershocks happen because the crust in the area where the main earthquake happened is adjusting to the earthquake's effects.
It depends on how big the earthquake is. A big earthquake will cause more damage to the area.
There hasn't been an earthquake as powerful as magnitude 5.9 in Virgina/Washington DC area since the Giles County (Virginia) earthquake in 1897 also recorded at magnitude 5.9.
hardest hit area of the haiti earthquake
it varies on how power the earthquake is and how the environment where the earthquake happened is. if the earthquake is powerful and the environment is strongly built the average kill will be very less compared to a strong earthquake and an environment which is not built strong enough.
Earthquake intensity is measured using the Modified Mercalli Scale. That is basically a 'subjective' scale (as opposed to the Richter scale, which measures magnitude), because intensity is measured by the impact is is reported to have on people and their property, as reported by them. So a big earthquake like 8 on the Richter scale can have a low intensity if it happens in an area where few people live. A small earthquake can be high-intensity if it happens in a crowded area with many ramshackle houses.
Bear in mind that it is not just the Richter scale measurement which determines the severity of a tsunami which results from an earthquake; the location of the earthquake is also relevant. And inland earthquake does not produce the same tsunami as an underwater earthquake. That said, 8.3 is an extremely powerful earthquake which could produce a tsunami that would travel for thousands of miles and cause immense dammage over a very wide area.
No it isn't. There are several factors which contribute to earthquake fatalities: the size of the earthquake, the amount of population in the affected area, and the quality of construction of the buildings in that area. So, a huge earthquake taking place in an unpopulated region of Alaska, for example, would cause few if any fatalities, whereas a much small earthquake in Haiti caused lots of fatalities, due both to density of population and to poor construction standards.
When an earthquake hits, people will get hurt, if you don't move out of the area.
No an earthquake is caused because in that certain area where the earthquake was , there was a fault line.
an earthquake hazard
there is a even chance that a earthquake will hit the same area again.
