WELLINGTON, Feb 26 (Reuters) - Sentencing for the tour booking agents and managers of an island in New Zealand where a volcanic eruption killed 22 people, mostly tourists, in 2019 began on Monday, with the prosecutor warning those sentenced may not be able to pay a fine.

There were 47 people on White Island, also known by the Maori name of Whakaari, when the volcano erupted on Dec. 9, 2019. Many of the survivors were badly burnt by searing gas and ash. Most of the victims were tourists from countries including Australia, the U.S. and Malaysia.

Tour operators White Island Tours, Volcanic Air Safaris, Kahu New Zealand and Aerius, along with the corporate owner of the island, Whakaari Management Limited, are being sentenced on at least one criminal charge related to insufficiently ensuring the safety of workers and visitors to the island. Each charge carries a maximum fine of NZ$1.5 million ($924,750.00).
