An island volcano erupted while tourists were visiting on Monday in New Zealand's Bay of Plenty.
By Tuesday, six people were confirmed dead. Eight others were feared to have died and about 30 have serious burns.
Tourist Michael Schade tweeted pictures of the eruption (seen above and below), saying: "My god, White Island volcano in New Zealand erupted today for first time since 2001.
"My family and I had gotten off it 20 minutes before, were waiting at our boat about to leave when we saw it."
Tour guides could be seen evacuating people minutes after the eruption.

On Tuesday, steam continued to rise from the White Island volcano.
New Zealand PM Jacinda Ardern (below, centre) gave a press conference with Police Supt Bruce Bird (left) and Whakatane mayor Judy Turner.
Ms Ardern said she shared the "unfathomable grief" of those who had lost family and friends.
The prime minister also met first responders at the Whakatane fire station.
A flag in Whakatane could be seen flying at half mast.
In Sydney, Australian Prime Minister Scott Morrison addressed media with Foreign Minister Marise Payne. Twenty-four of the people affected were from Australia.

White Island, also called Whakaari, is the country's most active volcano, seen below in 1999.
Tourist Ron Neil visited the island in January 2017 and took the photos below.
"We were obliged to wear helmets and gas masks as a condition of climbing the volcano," Mr Neil said.
"We were only allowed on the island because the risk of eruption that day was measured as 1, on a scale of 1-5.
"Still the sulphur fumes were choking."
