Six people are now known to have died following a volcanic eruption on White Island in New Zealand.
Thirty others are being treated in hospital – many of them for severe burns – and eight people are still unaccounted for.
A senior police officer has “strongly suggested” that those who are missing will not have survived.
In total, 47 people were on the uninhabited island at the time of the eruption. Most were from Australia and New Zealand – and tourists from the UK, the US, Germany, China and Malaysia were also affected.
Many of the visitors to White Island were on a day tour from a Royal Caribbean cruise in a nearby port.
Officials have confirmed that two Britons are being treated in hospital, but their names and conditions are unclear.
Here is what we know about those injured and killed.
THE PEOPLE WHO LOST THEIR LIVES
Experienced tour guide Hayden Marshall, from New Zealand, died following the White Island eruption and was the first victim to be publicly named.
His brother Mark described him as a “lovely young man” who died doing what he loved.
Julie and Jessica Richards
Julie Richards, 47, and her daughter Jessica are feared to be among the victims – and their family are desperately seeking information about their whereabouts.
Ms Richards’ sister, Barbara Whitehead, has said she has been “overwhelmed” by the lack of information from the authorities.
The pair had been travelling on the Royal Caribbean cruise liner.
Gavin Dallow, Lisa Hosking and Zoe Hosking
Gavin Dallow, a 53-year-old lawyer, is missing along with his 48-year-old partner Lisa Hosking, and her 15-year-old daughter Zoe.
Mr Dallow’s worried father Brian told ABC News: “They were in the island, that’s now been confirmed, but whether they got off or what happened we don’t know.
“This is the worst. If we knew that something happened to them, it would better than this waiting, I can tell you at the moment. Because we just have to hold our horses and hope for the best.”
Anthony, Kristine, Jesse and Winona Langford
Anthony and Kristine Langford – along with their children Jesse and Winona – are from Sydney and were among those visiting the island from the cruise ship.
Sydney’s Marist College North Shore confirmed the family were missing, saying in a statement: “Please have the Langford family in your prayers.”
Another tour guide, Tipene Maangi, is thought to have been on the volcano when it erupted, but the 24-year-old’s relatives have not given up hope.
His partner, Kuini Morehu-Waenga, suffered through a sleepless night and is “absolutely devastated,” according to New Zealand’s Newshub.
Matthew and Lauren Urey
Newlyweds Matthew and Lauren Urey, from Virginia in the US, were reportedly among those seriously burned in the deadly eruption.
His mother Janet said: “The phone rang at midnight. Then I heard a voicemail come on.
“It was my son. He said: ‘Mom… this is not a joke. A volcano erupted while we were on the island. We’re at the hospital with severe burns.'”
Mr Urey, 36, was airlifted to hospital in Christchurch with burns over 80% of his body – while his 32-year-old wife underwent surgery at an Auckland hospital with burns over 20% of her body.
