2010 Haitian Earthquake
○ Where and how:
The infamous 2010 earthquake occurred 25km from Port-au-Prince, Haiti’s capital. This region was the most densely populated area of the country, which increased the impact of this event significantly. The earthquake struck at 4:53pm local time on the 12th of January, with a depth of around 13km. This relatively shallow depth meant that most of the energy of the earthquake was released close to the surface, resulting in a devastating catastrophe. The event was first thought to be related to the Enriquillo-Plantain Garden fault but actually occurred on the newly discovered Leógâne fault located near the Caribbean and North American tectonic plate boundaries. The Leógâne fault is a blind fault meaning that it doesn’t disturb the surface of the earth, so cannot be perceived without proper instruments. The transform boundary slipped, causing a rupture in the fault, which is both a strike-slip and a thrust fault. The first shock had a magnitude of 7.0 on the Richter scale, with aftershocks averaging 5.9 occurring up to several days after the initial event.
