Berend Hollander, 16, and Matthew Hollander, 13, were touring White Island when it erupted, the Chicago Tribune reported. Both were pronounced dead after being transported to a nearby hospital.

Their parents, Martin and Barbara Hollander, are still unaccounted for, according to the Red Cross, which is assisting in recovery efforts at the scene.

Five years ago, the family of four moved to Sydney, where Martin Hollander was from, according to WLS-TV in Chicago.

“We are together with our family grieving the loss of our loved ones,” Barbara Hollander’s parents said in a statement sent to the TV station. “Our amazing daughter, Barbara Hollander and our son-in-law, Martin Hollander were a wonderful couple and parents to our grandsons.”

The death toll in the disaster reached 16 Thursday morning, with eight still missing and 31 more hospitalized, according to reports.

Those who survived the blast were severely burned by scalding steam and ash, reports said.

“It looked like a nuclear bomb going off,” said one witness who spoke to Radio New Zealand.

Some found themselves trapped on the island just as the volcano erupted, reports said.

According to Reuters news agency, some of the missing were seen on a webcam exploring the volcano’s crater just before the eruption happened.

Helicopter flights above the area’s dangerous terrain have found no signs of survivors.
