Port-au-Prince was once again rocked by a powerful earthquake, a 5.9 jolt that toppled buildings but apparently caused no further casualties.
The quake, as powerful as the strongest aftershock of the 7.0 shock of January 20, struck at 6:00 a.m. local time. Most of the population were sleeping outside, which is why there were no new casualties.
The epicenter of the quake was 35 west-southwest of Port-au-Prince.
A 4.7 magnitude aftershock struck the region on Sunday.
