A New Zealand volcano has erupted in a tower of ash and scalding steam while tourists were exploring the moon-like surface, killing five people and leaving perhaps two dozen others missing and presumed dead. Eighteen survivors have been taken off White Island. Authorities say the site is too dangerous for rescuers to search for the missing, and aircraft have seen no signs of life. People are questioning why tourists were allowed to visit the island after scientists noted a recent uptick in volcanic activity.
