(Euronews: 0615 PST, April 14, 2011) Japanese government scientists are concerned that another massive earthquake could be on the way. Aftershocks are continuing to shake Japan's northeast coast on an almost daily basis; on Thursday morning a tremor measuring 6.1 was registered.

"On March 11 (the day of the original earthquake and tsunami) there was an extremely large magnitude 7.7 aftershock off the coast of Ibaraki prefecture and so that's the the biggest aftershock at the present time," said Keiji Doi, Japan Meteorological Agency's head of earthquake prediction.
