Another strong earthquake hit the east coast of Japan early Monday morning, with a magnitude of 5.5, according to the US Geological Survey. The tremor was at a depth of 26 kilometers and hit just 324 kilometers east of Namie in the Fukushima Prefecture. Fortunately there was no tsunami alert from the Pacific Tsunami Warning Center this time and no evacuation was initiated.
On Friday, a 7.3 magnitude tremor struck 231 miles of the main island of Honshu, with the earthquake being felt in Tokyo and the northern island of Hokkaido as well. A tsunami alert was promptly issued, with the wave set to hit the Fukushima region as predicted by the Japanese Weather Agency. They issued a yellow warning, meaning the tsunami was not expected to be more than 1 meter high. A 1 foot tsunami was observed in Ishinomaki City, Miyagi Prefecture, but the good news was that it did not become stronger as was expected by meteorologists. A 1.8 foot tsunami was also detected at the Onagawa Nuclear Power Plant in Miyagi but the plant operator said the facility was built to withstand a 55 foot tsunami.
Meanwhile, the earthquake and tsunami alert prompted a quick evacuation of workers assigned near the sea wall at the damaged Fukushima Daiichi nuclear plant, according to Tokyo Electric Power Co. As of now, there have been no reported damage or abnormal readings at the plant, the site of the nuclear meltdown during the 2011 disasters. Those living in the coastal regions around the Fukushima coastline were also advised to move to higher areas. There were no reports of damage on land because of the earthquake, which according to the Japan Meteorological Agency was still an aftershock of the Great East Japan Earthquake of 2011.
