Five people from a Royal Caribbean International cruiseship have been confirmed dead and many more remain injured or missing following the eruption of a volcano they were visiting on an organized tour while on a cruise around New Zealand.

A total of 47 people, the majority of whom were passengers or crew on Royal Caribbean’s 168,700-gt cruiseship Ovation of the Seas (built 2016), were on Whakaari/White Island, a live volcano off the east coast of New Zealand’s North Island when it erupted abruptly yesterday afternoon.
