Nature: The public prosecutor of L’Aquila, the Italian town hit by a devastating earthquake in April 2009, is investigating whether six Italian seismologists should be charged with manslaughter for failing to warn citizens of the impending quake. Nicola Nosengo of Nature reports on the investigation, which stems in part from a press conference held six days before the quake. At that conference a government official declared, “The scientific community tells us there is no danger, because there is an ongoing discharge of energy. The situation looks favorable.”
