Northern Italy was shaken by an aftershock Monday morning, a day after a magnitude-6.0 quake killed at least seven people and left thousands of survivors huddling in tents or cars overnight. Monday morning's aftershock caused buildings to sway in the town of Finale Emilia, in Italy's industrial heartland, CNN reported. The tremor had a magnitude of 3.2 and hit near the site of the original quake, according to the Italian Seismic Service. The head of Italy's Civil Protection Department, Franco Gabrielli, said 11,000 people had been displaced by the first quake around 4 a.m. (10 p.m. Saturday ET) on Sunday morning. The government put 3,000 people up in tents or hotels.
