Jakarta, Feb 12 (IANS): A Strong and shallow undersea quake measuring 6.6 on the Richter scale rocked East Nusa Tenggara in Indonesia on Friday, but it was not a potential for tsunami, the Meteorology and Geophysics Agency of Indonesia said.
The US Geological Survey reported that the quake was of 6.5 magnitude with the depth of 30.5 km under seabed, according to Xinhua.
The Indonesian agency said the quake was recorded at 17.02 p.m. (Jakarta time) with the epicentre at 14 km southwest of Sumbawa Barat of East Nusa Tenggara under sea bed, an official of the agency told Xinhua by phone.
