SYDNEY, Rabi'I 02, 1439, November 20, 2017, SPA -- Tsunami waves have been observed in New Caledonia and Vanuatu after a magnitude 7 earthquake struck between the Pacific Islands on Monday, the Pacific Tsunami Warning Center said, according to Reuters. The agency said waves as high as 1 metre (3.3 ft) above the high-tide mark were forecast to hit New Caledonia and smaller waves were expected in Vanuatu. It said the actual size of the waves would vary depending on the coastline, with barrier reefs reducing wave height, and warned that the initial wave may not be the largest. An undersea earthquake of magnitude 7.0 struck 82 kms (51 miles) east of New Caledonia's Loyalty Islands at 9.43 a.m. local time (2243 Sunday GMT). --SPA 02:56 LOCAL TIME 23:56 GMT www.spa.gov.sa/w541202
