4:53 p.m.: A killer quake of magnitude 7.0 strikes 10 miles west of Port-au-Prince, causing untold deaths, collapsing thousands of buildings, severing roads, putting the city's main seaport out of operation, crippling the city. A tsunami warning is issued, later canceled.
By nightfall: fires dot a landscape darkened by the loss of electricity; local hospitals are damaged, overwhelmed; the injured can be heard screaming in the rubble; residents claw at it with bare hands trying to rescue those trapped.
In Port-au-Prince: The U.N. peacekeepers' headquarters collapses, with hundreds missing; Red Cross, Salvation Army and other aid organizations spend their first hours looking for their own workers.
About 10 p.m.: One final commercial flight from Port-au-Prince arrives at Miami International Airport, with relieved but worried passengers.

U.N. peacekeepers crisscross Port-au-Prince's main Toussaint L'Overture International Airport runway in armored vehicles to keep order.
A team of doctors from the University of Miami/Jackson Hospital arrives to treat injured, part of U.S.-Haiti Operation Medishare; it flies back a few hours later carrying several Haitian residents gravely injured by the quake.
As darkness falls in Port-au-Prince, shantytowns spring up in every open space, including the manicured lawn of the crumbled Haitian National Palace; homeless erect cloth and cardboard shanties on the soccer field at Stadium Sylvio Cator; people afraid of buildings sleep in cars, on open ground.
