Chile has been hit with a strong aftershock today just under a week since Saturday’s devastating earthquake. The US Geological Survey said the aftershock had a magnitude of 6.6 and struck just twenty-five miles off the area of Concepción, which was badly damaged in the initial quake. The Chilean government, meanwhile, has significantly lowered the estimated death toll from over 800 people to around 279. Chilean officials say missing people were mistakenly included on the initial list of the dead. The toll could significantly rise again, however, with many people still missing and bodies still uncounted. Chilean President Michelle Bachelet said Chile suffered an estimated $30 billion in damages and would need at least three to four years to recover. Bachelet has declared a three-day period of mourning beginning on Sunday.
