MIRANDOLA, Italy, May 29 (UPI) -- A 5.8-magnitude earthquake in northern Italy Tuesday killed 15 people and collapsed buildings already weakened by an earthquake last week, authorities said.
The quake, and tremors that followed, led to the evacuation of 5,000 people, Italy's ANSA news agency reported.
Emergency shelters were being set up in camps, at hotels and aboard trains.
Agenzia Giornalistica Italia said dozens of Mendolla warehouses where employees had been working inside have collapsed.
The morning earthquake was followed by 40 other tremors in the Emilia Romagna region, including ones measure at 5.3-magnitude and 5.1-magnitude, AGI reported.
Prime Minister Mario Monti said Italy would do whatever was necessary to return the Emilia Romagna region to normal, ANSA said.
"I guarantee that the State will do everything that it has to do, that it is possible to do, to ensure this very special, important and productive region for Italy can return to its normal life in a short period of time," Monti said.
The 5.8-magnitude earthquake shook the region about nine days after a 6-magnitude temblor killed seven and caused extensive damage to structures, many of which collapsed Tuesday, officials said.
In Milan, residential buildings and offices were evacuated for fear they would collapse. People also rushed into the streets from their homes and workplaces in Bologna.
The epicenter of Tuesday morning's quake was in Mirandola in Modena province, about 25 miles from Bologna, officials said. The quake also was felt in Milan, Genoa and in the regions of Veneto and Trentino.
The earthquake interrupted or slowed down train service, ANSA said.
The mayor of San Felice sul Panaro, a town that sustained major damage last week, told reporters he feared more victims would be found beneath the rubble, the British newspaper The Guardian reported.
In the town of Finale Emilia, a castle damaged last week reportedly suffered more damage Tuesday. The cathedral in Mirandola, also damaged in the earlier quake, was reported to have sustained more structural damage.
