Hong Kong CNN —A 7.8 magnitude earthquake struck the South Pacific on Friday, the US Geological Survey (USGS) said, triggering a tsunami warning for nearby nations including Vanuatu, Fiji and Kiribati. The US National Tsunami Warning Center issued a tsunami alert for coasts located within 1,000 kilometers (621 miles) of the epicenter which lay between Fiji, Vanuatu and New Caledonia. Tsunami waves reaching up to 1 meter are possible along some coasts of Vanuatu, according to the US National Tsunami Warning Center, downgrading an earlier assessment that said waves could be 3 meters high. Smaller waves below 0.3 meters could be expected in Fiji, Kiribati and New Zealand’s remote Kermadec Islands, the warning center added. New Zealand’s National Emergency Management Agency tweeted that it is assessing whether the quake “poses any tsunami threat to New Zealand.”The quake was earlier reported to be at 7.7-magnitude but has since been revised up.
