(Previous LONDON, adds no major damage in Aden) ADEN, Yemen, Dec 30 (Reuters) - An earthquake with a magnitude of 6.3 struck the Gulf of Aden between Yemen and Somalia on Saturday, but initial reports from Yemen said it appeared to have caused little damage. The quake was at a depth of 10 km (6.2 miles), the U.S. Geological Survey (USGS) said on its Web site, but residents of Yemen's port city of Aden said they did not feel it. There did not appear to be any serious damage or injuries in Aden and the sea looked calm, one resident said. It was not clear whether the earthquake had a more serious impact on nearby Somalia. The quake struck at 11:30 a.m local time (0830 GMT), the USGS said. It located the quake some 240 km to the west of the Yemeni island of Socotra and 325 km north of Xaafuun on the Somali coast.
