A tsunami warning has been lifted and residents of Okinawa are breathing a sigh of relief after an earthquake rattled the southern Japanese island early Saturday morning. " First there was a strong vertical shake, then sideways," an official of the city of Naha tells Reuters. "The strong quake lasted for about 10 seconds ." There were no immediate reports of damage or casualties on the eight American military bases in the area, CNN reports.
