The Vanuatu earthquake may have been far distant from areas with large populations (M.Ted), but effects of tsunamis are widespread.

The quake was on the boundary of the Australian plate, and tsunami warnings were given to Australia, Indonesia, New Zealand as well as many island communities including Guam, Samoa, Tonga, the Marshalls, etc. Although no severe waves were generated and the warning lifted later, the possibility of damaging waves was there.

Gargoyle, thanks for the link to the Quake Map; most educational.
