9.0 Earthquake strikes Japan


Recommended Posts

Any chance this may lead to the eruption of Mt. Fuji. The previous "largest earthquake in Japan" lead to its eruption 49 days later.

You're talking about Kanto yes? I guess its possible, but I believe the epicenter of Kanto was much closer to Fuji than this earthquake's epicenter was.

is it commom for aftershocks to occur so far away from the main quake?

Yes, since it's a subduction zone earthquake. Indeed, even though the 8.9 has a "center", if I remember correctly, that is just where the first slippage occurred. The actual 8.9 earthquake was a result of a large section of the subduction zone fault slipping. That's illustrated by the box in this USGS map:

In other words, the star is the "epicenter" of the earthquake, but the box is the actual region that slipped.

Not the San Andreas. Can't get above 8.4 or so without a subduction fault, just not enough fault plane to rupture. The Cascadia Subduction Zone extends to extreme Northern California and could generate a 9-9.4.

What about the New Madrid fault in the S.E. US. What is the magnitude potential there?

mid 8's, but the problem is the subsurface the crust in the east allows for more violent shaking over a larger area, a major in this area would be felt 5-10 times further away then something that hit over the west coast.

when new madrid goes again, st. louis, memphis and little rock will be god awful especially with the lack of earthquake building code, and the severity and amount of shaking that'll occur.

If there were another 8.0 anytime soon, it would be the worst natural disaster in US history. More likely is something in the 6-6.9 range in the next 30 to 50 years, which would cause enough problems given all the population/development.

That is a very active fault currently but there is some speculation that the frequent, localized seismic activity N of Little Rock is related to the natural gas 'fracking' tests that are currently being conducted.

Ya it most likely is. I'm talking about a 8.0 or greater like in the 1800's those mini quakes are most likely fracking activity

Action News, baby. Tsunami done, meltdown not quite.

Ya the US news stations can really only report on what NHK and others are visually providing, and i'm sure the tsunami areas have no fly zones right now as military rescue operations are ongoing so they are just reporting on the reactor stuff which is being actively watched and has cameras on it.
