The search for the 16 people who remain missing after the January 13 shipwreck of the Costa Concordia cruise liner off the Italian coast was broken off Sunday due to shifting by the half-sunken ship, reported the Italian news agency Ansa.
Instruments showed a shift of three and a half centimetres within six hours, reported the agency.
The ship is lodged on the underwater boulders upon which it ran aground, but still can tilt as it settles. Too much movement is dangerous for the divers who continue to search the 290-metre-long vessel, dpa reported.
Efforts to pump out the ship's fuel were already broken off Saturday due to inclement weather. A 17th body discovered Saturday has been confirmed as that of a Peruvian member of the ship's crew.
