NW Cal had a 6.5 on 1/4/10 and a 6.0 on 2/4/10. Never felt the second one. The thrill you get is dependent on how close you are to the epi-center and the depth...
lol!
Tell ya what, while making more margarita mix, I'll go look in my freezer so I can relate...But only for a second....lol
Ladyvet, I didn't see your earlier post above until just now. In case you haven't seen this, here is good news from the Japan Meteorological Agency I posted earlier:
Canceled
Tsunami Advisory
OKINAWA ISLANDS
DAITOJIMA AREA
AMAMI ISLANDS AND TOKARA ISLANDS
MIYAKOJIMA AND YAEYAMA AREA
No tsunami damage at the above coasts though there may be slight sea level changes from now on.
All tsunami warnings and advisories have been cancelled.
Bump. Thanks for that link.
Here is some interesting material I found on Japan's Prediction Research Center site.
Before the election debacle in 2008, I was wondering why the USGS person responsible for posting twitter updates spent a significant portion of time promoting the candidate turned current so-called CIC living in the White House. If USGS is funded at all by taxpayer money, it's long past time for an overhaul of that agency.
Large earthquakes repeatedly occur along a large-scale fault, and the entire recurrence process includes the following stages:
An earthquake cannot occur without any accumulation of the elastic strain energy in the medium surrounding the fault. In this sense, stage (II) may be regarded as the preparatory process in a broad sense, which is characterized by the process of elastic deformation. In this stage, tectonic stress level is below critical, and the amount of the stored strain energy is insufficient to cause the ensuing large earthquake on the same fault. As the tectonic stress continues to build up, the stress eventually reaches a critical level. At this final preparatory stage (III), an enough amount of the strain energy has been stored. Laboratory studies demonstrate that local concentration of deformation inevitably occurs and rupture begins to nucleate if the fault is characterized by mechanical and/or structural inhomogeneity. The nucleation may be accelerated by a triggering effect of stress transfer due to fault-fault interaction. Fluid-solid rock interaction may be activated at this stage as well because of high tectonic stress, and the nucleation may also be accelerated by activation of the fluid-rock interaction. In spite of these possible accelerating effects, a large earthquake will be preceded by a slow growth of the nucleation, though the time to the ensuing earthquake may be shortened by these possible effects. This stage may be regarded as the preparatory process in a narrow sense. The process of earthquake dynamic rupture during which short-period seismic waves are generated is characterized by rapid stress drop with ongoing slip on the fault, and almost complete release of the stored strain energy. The phase of rupture arrest and its aftereffect are characterized by time-dependent stress relaxation and stress transfer, and as a consequence, aftershocks and aftereffect of crustal deformation follow. |
LOL! Okay, enjoy. But please, if you're anywhere in California or any other EQ zone, please get your earthquake preparations in order.
Great stuff on the process of distributing the released energy we call the S/wave, good stuff and thanks!
Oh good. I have not heard from them yet so I’m figuring no news is good news. Thanks.
Thanks BD...Following
What I am finding a bit odd is that there has been no aftershock as of yet?
A quake this size I would think would have generated something quite large already.
Just noticed this on the World site USGS and hadn’t heard about it yet...was at the Dr. so no news!
Thanks for the thread bd...
I check the earthquake site...once or twice a hour every single day.
Today's earthquake was preceded by a quake six days prior in the same area.

Here is a list of the earthquakes located by the USGS and contributing networks for the 10-degree Map Centered at 25°N, 130°E. Most recent events are at the top. (Some early events may be obscured by later ones on the map.) Click on the date portion of an earthquake record in the list below for more information.

You're welcome, Pollywog. I got the news as soon as it happened, tried posting it but there was some sort of lag here on FR.
Glad to hear you're keeping track too. It's good to stay aware and prepared. There was a tiny quake here in California not far from Baker about three hours ago but it was not close to any significant fault line.
Are you following the latest storm news? Ernest has been doing an awesome job tracking the latest info. :)
Heh, shades of . . .
So, you've been thru it as well...It's something that you never forget. And I can understand how some of those people in Haiti couldn't move to get out of the way of falling debris, etc.
It's frightening.

You're welcome and glad you found it to be of interest.
Thank you! :)
Agreed. I subscribe to the USGS RSS feed and there is nothing listed yet for the area since this quake.
Interesting stuff.
