Netflix released a documentary about a 2019 volcanic eruption in New Zealand.
The eruption occurred on an island called Whakaari, which is an active stratovolcano.
Whakaari is privately owned by the Buttle family and is a popular tourist destination.
In the months leading up to the eruption, there were increased levels of gas, steam, and mud being ejected from the island's crater.
An earthquake occurred near the island in November 2019, and a high alert was issued.
Despite this, tours to the island continued.
On the day of the eruption, there were 47 people on the island, including tourists and tour guides.
Two short eruptions sent a plume of boiling ash and vapor into the air.
23 people were rescued from the island, while 22 people died and 25 people suffered injuries.
The rescue mission could have happened sooner, according to a medical director.
The prime minister called the scale of the tragedy "devastating."
