A powerful 7.1-magnitude earthquake struck the Pacific Ocean far north of New Zealand on Monday, generating a small tsunami that reached a neighboring island. The quake was centered 74 kilometers southeast of Raoul Island and was initially estimated as a 7.3 magnitude but later revised down to 7.1. Although the quake was shallow, only 49 kilometers below the seabed, there is no threat of a larger tsunami. New Zealand's National Emergency Management Agency asked people to avoid swimming and to stay off the beach, but quickly lifted the warning when it was determined there was no wider threat. Despite being within the Pacific Ring of Fire—an arc of fault lines around the Pacific Basin prone to large earthquakes—and a region of frequent large earthquakes, New Zealand's National Emergency Management Agency believes this quake is unlikely to have caused a tsunami that will pose a threat to New Zealand. The quake follows a series of devastating earthquakes along the country's East Coast last year.
