El terremoto de chile fue de 8.8Mw y el de Japón ha sido de 9Mw.

Me refiero al de Valdivia (Chile) de 1960, no al del año pasado.

Ok no había caido. ,que factor fue(principalmente), por cierto, el que hizo que subiera la calificación de ese terremoto la duración  o la intensidad??? y en este último???

TOKYO, March 15 (Reuters) - Japan's top government spokesman said on Tuesday that some damage has been detected at the quake-hit Fukushima Daiichi No.2 nuclear reactor in northern Japan, but that no sharp increase in radiation levels has been seen.

The damage was found in the suppression pool, which is attached to the No.2 reactor's containment vessel at the plant operated by Tokyo Electric Power Co <9501.T>, Chief Cabinet Secretary Yukio Edano told a news conference.

Edano said the suppression pool is used to turn vapour into water, but did not elaborate further on the damage.

TOKIO, 15 de marzo (Reuters) - El portavoz del Gobierno de Japón dijo el martes que algunos daños se ha detectado en la afectada por el sismo del reactor nuclear de Fukushima Daiichi N º 2 en el norte de Japón, pero que ningún aumento en los niveles de radiación se ha visto.

El daño fue encontrado en la piscina de supresión, que se adjunta a la vasija de contención del reactor N º 2 de la planta operada por Tokyo Electric Power Co <9501.T>, el secretario del gabinete Yukio Edano dijo en una conferencia de prensa.

Edano dijo que la piscina de supresión se utiliza para convertir el vapor en agua, pero no dio más detalles sobre los daños.

O está mal redactado o es de suponer que es seguro que se ha perforado la vasija, porque si está dañada la piscina que está afuera.... A ver si confirman daños en el reactor o no de una vez. El gobierno nipón no se atreve a mover un dedo, para que no se desplome el yen a primera hora...

Implementation plan of rolling blackout on and after Tue, March 15, 2011


Due to the Tohoku-Chihou-Taiheiyo-Oki Earthquake occurred on March 11,
the power supply-demand balance within our service area has been very
critical. As such, we have decided to implement rolling blackout on
and after March 15, which was started on March 14. We sincerely regret
to cause the anxiety and inconvenience to our customers and the society.
We will continuously make every effort to restore stable power supply
as soon as possible.

○Implementation plan of rolling blackout on Tue, March 15
  Regional block and time periods planned to have rolling blackout are as
  follows. The actual extension of blackout for each block are planned to
  be approximately 3 hours each.
  For customers who will be subject to rolling blackout, please be prepared
  for the announced blackout periods. Also for customers who are not
  subject to blackouts, TEPCO appreciates your continuous cooperation in
  reducing electricity usage by avoiding using unnecessary lighting and
  electrical equipment.

[Expected rolling blackout regions]
Block 3: 6:20 - 10:00
Block 4: 9:20 - 13:00
Block 5: 12:20 - 16:00
Block 1: 15:20 - 19:00
Block 2: 18:20 - 22:00

●Please refer to the attachment1 for the detailed region of the blocks.
●Starting and ending time of blackout periods may slightly differ.
●Depending on supply and demand conditions on the actual days,
  planned blackouts may not been carried out or may be implemented at
  times which were not previously announced.
●The website of TEPCO provides information including "Chome".
  http://www.tepco.co.jp/index-j.html

○Implementation plan of rolling blackout from Wed, March 16 to Fri, March 18
  Please refer to the attachment2 for the detailed plan.

●Please refer to the attachment1 for the detailed region of the blocks.
●The rolling blackout is scheduled in the same order every day, but
  time of blackout periods may be subject to change.
●Starting and ending time of blackout periods may slightly differ.

Press Release (Mar 14,2011)
White smoke around the Fukushima Daiichi Nuclear Power Station Unit 3 (3rd release)


At approximately 11:01am, an explosion followed by white smoke occurred
at the reactor building of Unit 3. It was believed to be a hydrogen
explosion.

According to the parameter, it is believed that the reactor containment
vessel remains intact. However, the status of the plant and the impact
of radioactive materials to the outside environment are presently under
investigation. (previously announced)

As of 1:30 pm, 4 TEPCO employees and 3 workers from other companies have
sustained injuries (all of them are conscious). 3 ambulances are in
operation to care for them and 2 have already dispatched the casualties
to the hospital.

As of 0:30 pm, the measured value of radiation dose near MP6 was 4μSv/h.
The increase of the radiation dose cannot be confirmed at this time.

As of 0:30 pm, the measured value of radiation dose at the monitoring
post in Fukushima Daini Power Station located approximately 10 km south
of Fukushima Daiichi Power Station remains at the same level.

In light of the incidents that have occurred at Units 1 and 3, we are
considering applying prevention measures to the wall of the reactor
building to ventilate the hydrogen gas contained in Unit 2.

TEPCO continues to take all measures to restore the safety and security
of the site and are monitoring the site's immediate surroundings.

  had been done by the Reactor Core Isolation Cooling System, however,
  At 6:07am, Mar 12th, the temperature of the suppression chamber exceeded
  100 degrees. As the reactor pressure suppression function was lost, at
  6:07am, Mar 12th, it was determined that a specific incident stipulated

Occurrence of a Specific Incident (Failure of reactor cooling function) Stipulated in Article 15, Clause 1 of the Act on Special Measures Concerning Nuclear Emergency Preparedness


At 2:46PM on March 11th 2011, the turbines and reactors of Fukushima
Daiichi Nuclear Power Station Unit 1 (Boiling Water Reactor, rated output
460 Megawatts) and Units 2 and 3 (Boiling Water Reactor, Rated Output 784
Megawatts) that had been operating at rated power automatically shutdown
due to the Tohoku-Chihou-Taiheiyou-Oki Earthquake.
(previously announced)

In response, water injection into Unit 2's reactor were being carried out
by the Reactor Core Isolation Cooling System. However, as the Reactor Core
Isolation Cooling System failed today, it was determined that a specific
incident (failure of reactor cooling function) stipulated in article 15,
clause 1 has occurred at 1:25 pm today.

Buenas noches, estaba viendo vídeos en youtube sobre el terremoto y me he encontrado con esto:

Fijaos en el minuto (más o menos) 1:24 de este vídeo: http://www.youtube.com/watch?v=2GzDDHnKFpw

Y ahora fijaos en este: http://www.youtube.com/watch?v=o-C6KyzYSaU

¿Qué tendrá que ver la velocidad con el tocino? Esto demuestra que nos tenemos que fiar de la mitad de lo que vemos y que hay que contrastar mucho la información para que no nos la cuelen, o quizá se trate de rellenar para impresionar más (como si ya no impresionase lo suficiente lo que hay).

Un saludo.

Os dejo un buen artículo acerca de la formación y propagación de tsunamis.
