SYDNEY: A shallow 6.5 magnitude earthquake struck in the Pacific off the Solomon Islands on Friday, seismologists said, but no tsunami threat was issued and no major damage was expected. The quake hit 154 kilometers (96 miles) southwest of Dadali and 170 kilometers west of the capital Honiara, according to the US Geological Survey. The earthquake was followed by a 5.3 magnitude aftershock. “Based on all available data a destructive Pacific-wide tsunami is not expected,” the Pacific Tsunami Warning Center said. The Solomons are part of the Pacific “Ring of Fire,” a zone of tectonic activity known for its frequent earthquakes and volcanic eruptions.
