SYDNEY, May 20 (NNN-AAP) – An earthquake with a magnitude of 7.1, jolted south-east of the Loyalty Islands at 01:51 GMT last night, the U.S. Geological Survey (USGS) said.
According to the latest update from the USGS, the epicentre, with a depth of 36 km, was determined to be at 23.062 degrees south, latitude, and 170.456 degrees east, longitude.
The U.S. Tsunami Warning System said that, the earthquake is with a magnitude of 7.4, and tsunami waves are forecast to be less than 0.3 metres above the tide level, for the coasts of Fiji, Kiribati, Vanuatu and Wallis and Futuna.
Actual amplitudes at the coast may vary from forecast amplitudes, due to uncertainties in the forecast and local features. In particular, maximum tsunami amplitudes on atolls and at locations with fringing or barrier reefs will likely be much smaller than the forecast indicates, it added.
An aftershock with a magnitude of 6.5 hit south-east of the Loyalty Islands at 02:09 GMT, according to the USGS. Besides, a 7.7-magnitude earthquake jolted south-east of the Loyalty Islands, as well, yesterday at 02:57 GMT.– NNN-AAP
