About 47 people were visiting White Island, an active volcano in New Zealand, when it erupted on Monday. Days later, many of their loved ones are still searching for information about them.

Eight deaths have been officially confirmed, including two who succumbed to their wounds at the hospital, and dozens of victims suffered injuries. On Wednesday, the New Zealand police released a list, which they said was incomplete, of nine missing people, of whom seven were from Australia and two from New Zealand. Family members of four people on the list confirmed that they were dead.

The toll was almost sure to rise. “We can never say 100 percent, but I would strongly suggest that there is no one who has survived on the island,” John Tims, the deputy commissioner of the New Zealand Police, said on Tuesday.

Many of the hospitalized people had suffered severe burns, and the police said Tuesday that they were still trying to identify both the dead and the injured. Rescuers could not go to the island on Wednesday to retrieve victims’ bodies for fear that the volcano might erupt again.
