TOKYO (Kyodo) -- A 10-meter tsunami was observed at Sendai port in Sendai, Miyagi Prefecture, in northeastern Japan, at around 3:55 p.m. after a powerful earthquake with a magnitude of 8.4 [upgraded to 8.9] rocked the region Friday, local police said.
A 7.3-meter tsunami was also observed in Soma port in Sendai and elsewhere, the [Japan Meteorological Agency] said, adding a 4.1-meter tsunami was observed in Kamaishi port in Iwate Prefecture in northern Japan, the agency said.
Anyone know the status of the nuclear reactors on this coast? My rough reading is that they must have seen a direct strike. In particular Onagawa NPP is extremely close to the epicenter.
(Update) To answer my own question:
(Reuters) - A fire broke out at Tohoku Electric Power Co's (9506.T) Onagawa nuclear plant in northeastern Japan following Friday's major earthquake, Kyodo news agency said.
Also, at another NPP (!!!)
(Reuters) - Japan said on Friday a cooling function at Tokyo Electric Power's (9501.T) Fukushima Daiichi nuclear plant was not working after a major earthquake but that it was trying to get backup power for cooling.
The government has declared an emergency situation as a precaution but there was no radioactive leakage and no damage from the cooling problem was expected at this stage, Chief Cabinet Secretary Yukio Edano told a news conference.
(Note that the first article contradicts the second; the second was published an hour later so I assume the first was in fact wrong?)
Emergency diesel generators not working, reports NEI magazine (Nuclear Engineering International, not the lobby group Nuclear Energy Institute):
-Utility TEPCO has requested the establishment of a nuclear emergency response programme for Fukushima Daiichi 1&3 and Fukushima Daini 1.
JAIF reported that Fukushima Daiichi 1, 2 and 3 automatically shut down; units 4, 5 and 6 were in maintenance outages. Fukushima Daini 1, 2, 3 and 4 automatically shut down.
JAIF has reported that TEPCO sent the emergency report because emergency diesel generators at the two sites are out of order. It said that there is no report that the radiation was detected out of the site. It said that an emergency headquarters has been set up and will issue information hourly.
One of the emergency coolant systems has been activated (not elaborated which):
Kyodo also reported that an emergency core-cooling unit had been activated at Fukushima nuclear plant, without giving further details.
