A magnitude 5.2 aftershock struck Haiti on Sunday, even as survivors of the previous day’s temblor were sifting through the rubble of their cinder block homes. The death toll stood at 12, with fears it could rise. The U.S. Geological Survey said the epicenter of the aftershock was located 15.8 kilometers north-northwest of Port-de-Paix, the city hard hit by Saturday night’s 5.9 magnitude earthquake. Sunday’s aftershock had a depth of 10 kilometers.
