Tokyo earthquake reports - Japan prelim magnitude 7.3 - off Fukushima (Tsunami Imminent)

a reply to: IronBoy

Do you have any idea as to what those towers contain?











I thought not.

They are saying second and third waves likely to be higher than first waves as they continue to come in.

Yes, this is in fact fairly common. However, it is all proportional to the energy released. So fortunately, because this was a mag 7.3 quake (or 6.9 according to USGS's reviewed data), the sort of waves it would generate would typically be much smaller than those produced by the March 11, 2011 mag ~9.0 quake.

Put it this way: we are not going to see 10-metre-plus tsunamis from this event. Their estimate of up to 3 metres would be for some localized areas where the lie of the land (by the coast) can allow for higher cumulations.

I'm not trying to play this down, however. This is still a worrying event, because a quake around a mag 7 is still pretty big and can cause significant local shaking and damage. The fact that they are experiencing water/cooling problems at the damaged nuclear power plant is worrying. As another member mentioned already, we'd better hope this quake was not a foreshock for a larger event.

Looking at both Tepco webcams....

Everything looks okay... or as okay as it can get with three melted down reactors.


While everyone is always concerned with the melted down reactors....the two cooling towers are often over looked.

The tower between the 1 and 2 reactors contains deadly amounts of radiation....everything that was flushed during the original disaster is still inside those two towers.... if memory serves me correct, humans can get no where near that tower.... it is deadly in minutes.

If it falls and what is inside is allowed to blow in the wind....... it is going to be very bad for those down wind.

How large was the earthquake that caused the huge swells to go 2 miles inland near Fukushima in 2011? I remember watching that on live TV. Never seen anything that horrifying (tsunami wise) before.

Reporting they were able to restart the pump at the reactor now.

Thank God,

Let's all hope it remains stable,and a big thank you to all who are updating this thread .

Hopefully they have had enough time to evacuate the coast line.

BBC are saying it's likely the worst has hit.
Sorry to post non doom porn propaganda.
I hope the BBC is right, won't get me any doom loving stars if they are though lol

Hi J&C,

yes it could well have been. It's within range of the big March 2011 quake's fault zone. I'm just hoping that's all it is, because there is still plenty of subduction zone along that coastline that has not let go yet.

Correct. One of those towers had the spot that was measured at over 20 Sieverts.

That would be great....I am watching the local live feed and they are saying different. Not that BBC can't be correct, but the local news is what I am interested in.

They are now reporting over 1 meter waves so they are getting larger.

That quake on March 11, 2011 was around mag 9.0 to 9.1. Ie, pushing around 90-odd times the shaking of this event, and cca 900-odd times the energy release. IOW, it would take about 900 of today's quakes to release the energy of that one quake in 2011.

I imagine we are hoping the same for everyone in the region.

PLEASE!

The topic is not each other. Please stick to the topic. Thanks.

Do not reply to this message.

initially the depth was reported 10km now it is revised to 25km. How shallow the epicenter is greatly effects the tsunami.

a reply to: carewemust
I'm not sure if I read your post correctly. Please forgive me!

The 2011 one was 9.1. There was a 7.3 magnitude foreshock before that.

I'm not sure how others might feel regarding tsunami deadliness. I do remember the Boxing Day Tsunami in the Indian Ocean back in Dec 2004 was pretty brutal on the scale of things.
