The latest in a string of powerful earthquakes shook part of the southwestern Pacific on Friday morning, local time, leading to far-reaching tsunami concerns. The magnitude 8.1 earthquake occurred at 8:28 a.m. NZST Friday, or 2:38 p.m. EST Thursday, according to the USGS. The epicenter was located well northeast of New Zealand, but the shaking was felt on part of the country and nearby islands in the region. "[This] is directly related to the M7.4 in nearly the same location just under 2 hours before," the USGS said in a Tweet. "Both of those occurred on the subduction interface between Pacific and Australia plates." A tsunami warning was initially issued for the Kermadec Island region, but that was later changed to a tsunami advisory, where tsunami waves could reach 3 meters (10 feet), according to the Pacific Tsunami Warning Center (PTWC) A tsunami warning was issued for New Zealand coasts, the country's emergency management agency said. This includes the Great Barrier Island and part of the north-facing shores of the North Island. Tsunami waves are also possible along the coasts of Fiji, American Samoa and other nearby islands.
