 At least 177 survivors were rescued within the first 24 hours, but strong winds and sea currents hampered rescue efforts.Rescue workers in helicopters faced difficulties in distinguishing survivors from the sea foam created by high waves, and the survivors who had made it onto life rafts found it difficult to stay afloat in the stormy waters.The search and rescue team widened the search radius by hundreds of kilometers, but only a few more survivors were found in the following days, some of which were located by chance.
