According to data produced by the US Geological Survey, the smallest aftershock was a magnitude 2 earthquake that occurred on the 13th of January 2010.
It's epicentre was 18.55°N 72.78°W and it's hypocentre was 10km deep.
Please see the related question for more information about the Haitian aftershocks.
they happen as an aftershock of an earthquake ina dif. region.
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.
WWE Aftershock happened in 2005.
you can hide uder desks and tables or under door frames when an earthquake happens. there might be an aftershock so be careful. another thing you should know is get out when the earthquake stops.

2 of the undersuface tectonic plates collided just under haiti. this made an earthquake. as they skraped away from each other an aftershock was made
Tangshan, Hebei, China. Sources listed it as high as 8.2. It was followed by a major 7.8 magnitude aftershock 16 hours later.
The earthquake's epicentre (the point on the surface directly above the earthquake rupture zone) was 25 km WSW of the Haitian capital city, Port-Au-Prince. According to the US Geological Survey the exact co-ordinates were 18.457°N, 72.533°W. Please see the related question for more information.
the aftershocks accured one after the other and didnt stop the people still fear today that another aftershock could happen while they are asleep
Before an earthquake nothing perceptible to humans happen. Several types of animals act up though. During a earthquake the ground trembles. Depending on the magnitude this might be anything from a light tremble to a violent shaking. Most of the time nothing happens after an earthquake, but sometimes there is an aftershock, which is another earthquake of a lesser magnitude.
It depends! Depending upon the built-in energy at the epicenter before and after the earthquake (main shock), and/or the energy (especially stored at some weaker places) generated after the earthquake, aftershocks of an earthquake range in their time.For more details, refer: http://www.answers.com/library/Wikipedia-cid-1349 Aftershock
