Earthquake Activity Thread

[yamkin]

What the msm isn't picking up on is that the 5.3 happened 1/4 mile upstream from the Trinidad dam just close to Long's Canyon on the map. Had the quake struck directly under the dam itself no doubt there'd be some concerned faces right now.

Snow_Joke, very good point you have raised. It's very worrying there at the moment as there have been more quakes.

Just wondering why you guys think about all this chat on the internet 'majour new Madrid eartquake' etc?

My Twitter stream just exploded. Friend in Baltimore is reporting feeling the quake strong enough for everyone to be evacuated from the office building and all the phone line are down. Another friend in Brooklyn felt it as well with it strong enough to throw a mirror off the wall and even my sister in Toronto just called me to tell me they had a quake all within about 3 mins of each other.

very good site for updates but they are having server problems at present

there is also more information regarding the colorado quake as well

[Crepuscular Ray]

Certainly; it was felt as far away as Toronto apparently. Several key buildings in Washington appear to have been evacuated for a while, but chiefly because of fears that it was an explosion.

very interesting especially this recent activity...however is there any sites that show a month or weekly profile to compare against?

ah found one...

this gives a week profile and true enough USA does seem active today.

What is interesting is though the frequency of ones in colarado.

[Wynn D Woo]

0.1km seems very shallow, anyone hazard a guess at what might have caused such a shallow but strong quake, especially as I dont recall the area being a particularly prone earthquake zone?

[Argyllcraig]

The depth is around 6km..

This is itself is quite shallow for a quake.

The 0.1 will likely initially have been down to lack of instrumentation in the east and such events needing reviewed.

[weatherobsuk]

Oddly enough woke up after a quick hours-nap to the mother of all headaches before switching on the news and reading the ticker that the 5.9 had hit .DC, obviously being a eastern seaboard event my first thought was 'New Madrid' but seems likely now the Ramapo Fault is the candidate to blame. Another faultline on the 'watch list' for its close proximity to NYC further to the North and its geological history of creating some large +7 quakes.

http://en.wikipedia....ki/Ramapo_Fault

A quick seismology lesson for those wondering why these faults are 'active' away from plate boundarys.

All faults along the central/eastern parts of the US are thought to be once related to the Pangean shift which was part-responsible for the opening of the Atlantic crust 250mya to the continents we see today. The continental shelf of the US will one day split apart from New Orleans right up into the Great Lakes following the 250mya Pangean-fault movement given the faults are interlinked within the continental shelf of the US itself. This location just happens to be where the US major population centers currently sit.

http://geohazards.us...qfaults/map.php

There is a known seismic hazard area throughout the region, doubtless related to the formation of the Appalacians a bit to the west.

I doubt this quake is directly related to the earlier Colorado quake: this area is one related to relatively new mountain formation (geologically speaking) while Colorado is ancient, ancient land, and there's a lot of faults between them that would presumably take the strain from the Colorado event - or slip beforehand.

NO IT WASN'T. Several buildings were for an hour or so.

I note you've changed your "eeek planetary alignment possible disaster run for the shelters dates" in your sig. to include today since this relatively minor earthquake struck and after your original timespan. Are you doing a Positive Weather Solutions and trying to rewrite your predictions perhaps?

[john pike]

The Times-Dispatch said the epicenter was not far from Dominion Virginia Power's North Anna nuclear plant. The quake knocked out power, but the utility said it had manually shut down both nuclear units without incident. "We did lose on-site power, but all the diesel generators are up and running," Dominion spokesman Richard Zuercher told the newspaper 30 minutes after the quake. "Everything appears to be operating just fine.

and at different times

odd

[Crepuscular Ray]

USGS says 5.8/9.

But if you thought that the alignment problems would continue beyond yesterday why didn't you put that in your original sig. on the subject?

That was a bit of an extrapolation. Your predictions for the effects of the now-over planetary alignment and the alleged impacts of Elenin and Nibilu have certainly implied that heading for shelters (where/if any exist) is the only possible means to survive.

Actually, given that until earlier this evening you were ending your warning period yesterday, yes, you are.

On earthquake matters

I guess RSOE is getting conflicting information as their sources analyse data from different sources. It will doubtless get clearer in a few hours.
