I know a couple places for reading Korean news in English (i.e: http://english.chosun.com/svc/list.html?catid=5 ), but I don't know any similar Japanese sources.

The Mainichi Shimbun, Asahi Shimbun, and Yomiuri Shimbun have some news in English.

From the Associated Press-- http://news.yahoo.com/s/ap/20110311/ap_ ... ke_science
Two days earlier, the region was rattled by a magnitude-7.2 quake that scientists now consider a foreshock.
Foreshocks are basically earthquakes and are only identified as precursors
after another quake follows them. After such an event,
there's only a 5 percent chance of an even bigger quake coming later.
(Emphasis added.) Let's hope the AP is correct.

I just read that this earthquake created a crack in the earth's crust, 290 km long and 90 km wide, so analysed by the USGS.

A crack? Created by a subduction fault? Do you have a link for that?

David Applegate, a senior science adviser for earthquake and geologic hazards for the U.S. Geological Survey, said the 8.9-magnitude quake ruptured a patch of the earth's crust 150 miles long and 50 miles across.

extremely difficult to find a good source but here is the link in english

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.

Wave heights? In...millimeters?

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.

Joaz Banbeck wrote: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..
