Japan Lifts Tsunami Warning: Japan has lifted a tsunami warning for its northeastern coast nearly four hours after a powerful offshore earthquake. A tsunami advisory for waves of up to 1 meter (3 feet) remains in place for much of the Pacific coast. The earlier warning was for waves of up to 3 meters (10 feet). The Japan Meteorological Agency had urged residents to flee quickly to higher ground. The largest wave recorded was 1.4 meters (4.6 feet) at Sendai Bay.
A utility official says he believes that a cooling water pump that stopped working at a Japanese nuclear power plant after a strong earthquake was shut off automatically by a safety system as the water in the pool shook. The utility says that a backup pump was launched to restore cooling water to spent fuel storage pool at the No. 3 reactor of the Fukushima Dai-ni plant. The plant is close to the Fukushima Dai-ichi plant that went into meltdown in 2011 after a tsunami swamped the plant, knocking out power to the cooling systems. Both plants are operated by Tokyo-based TEPCO. A magnitude 7.4 earthquake struck off Fukushima prefecture on Tuesday morning, sending tsunami waves toward the Japanese coast. So far, no major damage has been reported. Read More
