7.7-magnitude quake off the Pacific, no tsunami alert
WASHINGTON: A strong but deep 7.7-magnitude earthquake struck off the Northern Mariana Islands in the western Pacific on Saturday (Jul 30), but triggered no tsunami alert, US monitors said. The quake struck at a depth of 212 kilometres at 7.18am local time (5.18am Singapore time) some 30.5 kilometres southwest of the island of Agrihan, according to the US Geological Survey. No tsunami warning was issued. A self-governing commonwealth of the United States since 1976, the Northern Marianas consist of 15 islands, with more than 90 per cent of the population of 54,000 living on the main island, Saipan. Only four other islands are populated.
