IAEA Update: New earthquake in Japan (7 April, 17:30 UTC)

The IAEA confirms that an earthquake occurred in Japan at 14:32 UTC 7 April. The IAEA International Seismic Safety Centre has rated it as a 7.1 magnitude, revised from an initial 7.4 magnitude. The epicenter of the earthquake was 20 km from the Onagawa nuclear power plant and approximately 120 km from the Fukushima Daiichi and Daini nuclear power plants.
The IAEA has been in contact with NISA and can confirm the status of the following nuclear facilities:
Fukushima Daiichi Nuclear Power Plant
NISA confirms that no changes have been observed at the on-site radiation monitoring posts. The injection of water into the reactor pressure vessels of Units 1, 2 and 3 was not interrupted.
Fukushima Daini Nuclear Power Plant
NISA confirms that no changes have been observed of the readings at the on-site radiation monitoring posts.
Onagawa Nuclear Power Plant
All reactors have been in cold shutdown since the 11 March earthquake.
NISA has confirmed that two out of the three lines supplying off-site power to the site were lost following the 7 April earthquake. Off-site power continues to be supplied through the third line.
Cooling of the spent fuel pool was temporarily lost, but has subsequently been restored.
No change has been observed in the readings from the on-site radiation monitoring post. The status of the plant is currently being checked.
Tokai Daini Nuclear Power Plant
Tokai Daini nuclear power plant remains in cold shutdown since the 11 March earthquake. No abnormality has been observed.
Higashidori Nuclear Power Plant
NISA has confirmed that the Higashidori NPP was shutdown and in a maintenance outage at the time of the 7 April earthquake. Off-site power has been lost. Emergency power supply to the site is operating. All the fuel had been removed from the reactor core and stored in the spent fuel pool. Cooling of the spent fuel pool is operational.
Tomari Nuclear Power Plant (in Hokkaido)
At the time of the 7 April earthquake Tomari Unit 1 and Unit 2 were in operation. Following the 7 April earthquake, the Hokkaido Electric Power Company reduced the generating power to 90% of capacity.
Rokkasho Reprocessing Plant
NISA confirms that Rokkasho Reprocessing Plant and uranium enrichment facility lost off-site power. Emergency power supply to the site is operating.
The IAEA will issue further information as soon as it becomes available.
