SYDNEY: A 6.3-magnitude earthquake hit the Solomon Islands on Monday, the United States Geological Survey (USGS) said, but no tsunami warning was issued. The powerful quake struck just after 4 p.m. (1 p.m. in Manila) at a depth of 17.7 kilometers, some 140 kilometers southeast of the Pacific nation’s capital Honiara, the USGS added. The Solomon Islands Met Service said there was no tsunami threat from the undersea quake. Garedd Porowai, marketing team leader for Solomon Islands Tourism, said the tremor was “not the biggest” he had felt but it “gave us quite a jolt here in the office.” There was no visible evidence of damage in Honiara’s central business district, he added. The Solomon Islands are regularly rocked by strong quakes.
