Tonga earthquake: Magnitude 7.3 tremor triggers tsunami warning


A powerful undersea earthquake struck off Tonga in the South Pacific on Friday, prompting authorities to issue a tsunami advisory which was later lifted. The US Geological Survey said the 7.3 magnitude quake was centered 132 miles east-southeast of Neiafu, Tonga, at a depth of 15 miles.

He predicted strong shaking, but said the likelihood of serious damage or casualties was low.

The United States Tsunami Warning System initially issued a tsunami advisory, which is one step below a tsunami warning.

“There is no longer a threat of a tsunami from this earthquake,” the Pacific Tsunami Warning Center said at around 1:30 a.m.

The Tonga Meteorological Service has urged residents to move inland and boaters to stay away from the reefs.

“Please move inland immediately until further notice,” the service said on its Facebook page.

Please stay inland and high up and listen to the radio until further notice. For sailors, head away from the reefs to the deep ocean. Thank you Tonga MET.
