Major earthquakes have hit both Japan and Indonesia in the past 24 hours, but so far there are no reports of injuries.
Tokyo was shaken by a 6.1-magnitude quake early Monday, but no damage was reported. Reuters news agency quotes Japanese television as saying two runways at Narita International Airport were closed briefly for inspections. Experts say the quake struck northeast of Tokyo about 60 kilometers underground.
Sunday, a 6.8-magnitude earthquake off the coast of Indonesia rocked Sumatra's west coast. Residents of high-rise apartments in Singapore, 600 kilometers northeast of the quake's center, said they could feel their buildings swaying.
There have been no reports of a tsunami. A massive earthquake off Indonesia on December 26th triggered a tsunami across the Indian Ocean that killed more than 180,000 people. Nearly 50,000 are still missing.
Information for this report is provided by AP, AFP and Reuters.
