Dramatic new pictures have emerged of the panicked, final moments of the Costa Concordia as a damning new audio recording reveals the crew initially refused offers of help.
A taped ship-to-shore call, which took place 30 minutes after the liner hit a rock, reveals how senior officers on board were slow to act and intially denied there was anything seriously wrong.
The crew member was recorded telling the coastguard that the ship had suffered a power outage and said there was no emergency on board.
The conversation began at 10.12pm local time.
By then, many of the 4,200 passengers and crew had called relatives on their mobile phones asking them to alert the police, who in turn asked the coastguard to check on the state of the ship.
When asked by the coastguard if there are problems on board, the crew member replies: "We've had a blackout, we are checking the conditions on board."

Rescue teams work to find passengers and crew identified as missing
Despite further questioning by the port official, the crew member repeats that there has been a blackout, promising to keep the coastguard informed.
Meanwhile, divers are continuing to search for victims on the stricken cruise ship Costa Concordia in a race against time.
Forecasts of worsening weather are threatening to shift the ship off the rocks and send it to the bottom of the sea.
The head of the firefighters' diving team, Modesto Dilda, warned earlier of a "12 to 24-hour window to complete operations" but the chief firefighters spokesman, Luca Cari, has insisted there is no deadline set for completing the search.
Four more of those who lost their lives in the disaster have been identified.
Two bodies pulled from the wreckage earlier this week have been named as missing passengers Jeanne Gannard and Pierre Gregoire, both French nationals.
An Italian and a Peruvian have also been identified as emergency teams continue to look for the other 21 people still missing.
