An earthquake in the Pacific Ocean has caused a small tsunami. The quake, measuring 7.3 on the Richter scale, struck near Vanuatu early on Sunday, according to the US Geological survey.

No damage has been reported there, but the tremors come on the sixth anniversary of the Indian Ocean tsunami which killed 230,000 people.

Indonesia was one of the worst affected countries, but there are concerns it is still not fully prepared to cope.
