The 2010 Haitian tremor was a disastrous magnitude 7.0 Mw tremor.

Its epicentre was near Logne, roughly twenty-five km  west of Port-au-Prince, the capital of Haiti. The tremor took place at 16:53 local time  on Tues. , twelve January 2010, at a depth of 13 km. The tremor caused significant damage to Port-au-Prince, Jacmel and other settlements in the region.

Many important landmark buildings were noticeably damaged or demolished, including the Presidential Palace ( President Ren Prval, who was in the building at the time, escaped injury ), the nation’s Assembly building, the Port-au-Prince Cathedral, and the main jail. Many states responded to appeals for humanitarian help, promising funds and dispatching rescue and medical teams, engineers and support staff. Port-au-Prince’s morgues were quickly overwhelmed ; the Haitian government voiced on twenty-one Jan that over eighty thousand bodies had been buried in mass graves. As rescues tailed off, supplies, medical therapy and sanitation became concerns.

Delays in help distribution led straight to annoyed appeals from aid staff and survivors, and some pillaging and infrequent violence was noted.
