TAIPEI: A shallow 5.1-magnitude earthquake jolted waters off Taiwan and the southernmost tip of Japan Tuesday, US geologists said, but there was no immediate tsunami warning.
The quake hit at a depth of just six kilometers (four miles) and its epicenter was 181 kilometers east of densely populated Taipei, or 112 kilometers off the Japanese island of Ishigaki, the US Geological Survey said. There was no alert from the Hawaii-based Pacific Tsunami Warning Center.
