Strong quakes jolt eastern, central Japan

TOKYO (Kyodo) - A series of strong earthquakes continued to hit eastern and central Japan Tuesday but there were no immediate reports of injuries, the Japan Meteorological Agency and police said.
A powerful earthquake with a preliminary magnitude of 6.3 struck wide areas of eastern and northeastern Japan at around 2:07 p.m. Tuesday, following a magnitude 6.4 quake in the region at 8:08 a.m. and another with a magnitude 5.6 in central Japan at 7:26 a.m. Strong quakes also hit eastern Japan Monday.
No tsunami warning was issued. The weather agency said the 2:07 p.m. quake was likely one of the aftershocks of the March 11 earthquake with a magnitude of 9.0 and subsequent tsunami that devastated northeastern Japan.
After the 2:07 p.m. quake, workers at the troubled Fukushima Daiichi nuclear power plant in Fukushima Prefecture were ordered to evacuate temporarily, plant operator Tokyo Electric Power Co. said.
But power sources and pumps to cool down reactors there were not disrupted, according to the utility.
Workers at the neighboring Fukushima Daini nuclear power station were also ordered to evacuate, but the order was lifted soon afterward as no abnormality was found at its reactors.
No damage has been reported from nuclear power facilities in neighboring Ibaraki Prefecture, according to the prefectural government.
The National Police Agency said it has received no reports of human injury from the temblor, while the Fire and Disaster Management Agency said a fire broke out in Iwaki, Fukushima Prefecture, after the quake.
Bullet train services on the Tohoku and Joetsu shinkansen lines came to a temporary halt, operator East Japan Railway Co. said, adding that the services resumed about 10 minutes later.
The 2:07 p.m. quake measured lower 6 on the Japanese seismic intensity scale of 7 in the cities of Iwaki, Fukushima Prefecture, and Kitaibaraki, Ibaraki Prefecture.
Shaking of lower intensity was also observed in Miyagi, Yamagata, Tochigi, Gunma, Saitama, Chiba, Tokyo, Kanagawa and Niigata prefectures, the agency said.
The epicenter of the quake was in Fukushima Prefecture's Hamadori district facing the Pacific, the agency said.
After the 8:08 a.m. quake, the runways at Narita airport in Chiba Prefecture were temporarily closed for checks, the airport authority said.
Bullet train services on the entire Joetsu and Nagano shinkansen lines and parts of the Tohoku and Tokaido shinkansen lines were also temporarily suspended, according to Japan Railways Group companies.
The 8:08 a.m. quake, which is believed to be an aftershock of the March 11 quake, rocked the cities of Asahi and Katori in Chiba Prefecture.
The focus of the quake was in the Pacific off the coast of Chiba Prefecture, the agency said. Its magnitude was initially estimated at 6.3 but was later revised upward to 6.4.
The 7:26 a.m. quake shook the villages of Kijimadaira and Sakae in Nagano Prefecture.
The focus of the quake was in northern Nagano Prefecture, the agency said. Its magnitude was initially estimated at 5.5 but was later raised to 5.6.
On Monday, a strong earthquake with a magnitude of 7.0, which is also believed to be an aftershock of the March 11 temblor, hit eastern and northeastern Japan, claiming the lives of three people.
