Dozens missing after passenger ferry sinks as rescuers scour South Pacific coastline

At least one person has died and more than 30 others remain missing as search-and-rescue operations continue, according to a statement shared on Facebook by Vanuatu's Ministry of the Prime Minister.

The MV Matui was traveling between the islands of Ambae and Santo when it sank Friday, according to The Associated Press (AP). It had 47 people on board. 

Searchers rescued 15 survivors and recovered one body - but local authorities have now shifted their efforts toward the coastline as the hunt for the remaining passengers continues, AP reported.

Retired Coast Guard Capt. Aaron Davenport, based in Virginia, told Fox News Digital that several factors could determine the survival chances of those still missing.

"They may be clinging to debris. But as the days go on, the chances of survival are less and less," he said, adding that a lack of food and water, along with the risk of hypothermia, could reduce the chances of survival.

"This tragedy is a reminder that the safety of life at sea must come first," the ministry said. "Ship owners must ensure their vessels are seaworthy, carry all required safety equipment and have proper communication systems on board. Ignoring strong marine warnings puts lives at risk."

The government has launched a full investigation to establish the facts and help prevent a similar tragedy from happening again, the ministry said.

Fox News Digital previously reported that another deadly ferry disaster unfolded Aug. 30, when the Filo Jet catamaran, carrying 267 people, capsized off northern Cyprus.

Fourteen people died and another 14 remain missing, while 239 people were brought ashore alive. Search and recovery efforts are continuing.

Authorities are investigating the sinking as questions continue to emerge about what caused the vessel to go down.
