Japanese earthquake

While I can't tell either way, they way I read it, it could mean inside the earth's crust. Not actually referring to a visible hole in the surface of the crust. I think a 290km x 90km hole in the face of the earth would be garnering a bit more news than the quake itself.

With a large earthquake, a whole region of the crust can slip and rupture alongside the main fault, and along secondary faults, mostly miles under the surface, which is what they're referring to.

theyre referring to a crack in the crust but not in a straight line down but diagonal. so in my opinion a front view would look like this "/" not like this "|"

Wikipedia:
Megathrust earthquake
Subduction zone

As the one plate slides under the other, the edge of the top plate basically gets stuck. This places enormous stress on the sticking part which builds up over time and deforms the plates. When it finally slips, the top plate basically springs back, which is the motion which lifts or drops the land and water above it which creates the earthquake and tsunami. These are the most powerful types of earthquakes.

I don't know what the triangles are, but y'all may wish to see this: http://twitpic.com/48kgju/full.

Wave heights? In...millimeters?

EDIT: Nope, can't be millimeters

They're bouy numbers.

I heard about this while walking to class this morning. I hope that the majority of the people that the earthquake and tsunamis effect are ok.

The aftershocks keep hitting in a pattern that doesn't decline in frequency as much as one normally expects. This suggests that the so-called 'main' earthquake is just one of many foreshocks to something bigger. I fear that we may see something in the 9 or even 10 range within the next week, somewhere along the western edge of the Pacific plate, from Alaska to the Pilipines.

With all due respect Joaz, I hope that you're wrong about this.

Interesting article here relating to the recent earthquakes and tsunamis in a way (and to Joazs prediction in a way)...

FYI I say interesting.. not that it is true..

i hope this isn't going to escalate any further, that would be the worst thing right now.

Istanbul is also waiting an earthquake around 7. It is not comparable with the Japan earthquake. But, we're not ready. It will cause worst results in Istanbul.

I'm watching news from TV and I want to say that I really sorry.

Well, it's an astrologist, not a scientist, so I think we're safe. :-)

The moon makes a closer approach to Every month, and the Earthquake happened at a time when the tidal forces of the moon were not particularly strong. There might still be strong and dangerous aftershocks from the quake, but they have nothing to do with monthly cycles of the cosmos.

Jordus · **#34**

Yeah... Just thought it was interesting that this article was published just before or right about when all this happened.

I dont personally believe in any of it.

Now, with a full 48 hours having passed since the quake, the data are starting to smooth out. In the first 24 hours immediately after the 8.9 quake, there were 144 quakes of 5.0 or stronger in the area east of Honshu. In the second 24 hour period thereafter there were 67 quakes of 5.0 or stronger.
144/67 = 2.15, which puts it at slightly less than the expected rule of thumb. So it is starting to look like the 8.9 was the the big one in this sequence.
