Mount Tarawera, a 3,646-ft (1,111-m) high volcanic peak on New Zealand’s North Island, consists of several lava domes that were split apart by an explosive eruption in 1886, which destroyed surrounding villages and killed more than 100 people.

What ghostly apparition witnessed by a boatful of tourists, including a clergyman, is said to have been a portent of the eruption? Discuss
