A 5.2-magnitude earthquake shook northern Italy on Tuesday, geologists said. There were no immediate reports of injuries. The quake, with an epicenter near the Apennines mountain city of Parma, was felt from Milan and Genoa to Florence, according to the National Institute of Geophysics in Rome. The jolt was "strong but not destructive," institute head Enzo Boschi told the local SkyTg 24 news channel. He said officials were doing damage checks and searching for possible victims, but that so far no damages or injuries had been reported. The state railway agency said it suspended area trains while they inspect the tracks for any possible damage.
