Replying to you because it seems silly replying to myself and I mentioned this is a previous reply to you.

Jujuy - I said downgrade to 6.1 or possibly 6.0.

It has not hit the main pages yet but it does look as if it has gone down to a 6.0. Now showing 6.0 in the tensor solutions.

Kermadec is continuing to shake:

,What is the connection between this earthquake.usgs.gov...()and thisgeomag.usgs.gov...(),at the same day,hour, minute?October 7 2011,8:58:29 UTC.Could be because a strong EMP?

Arkansas still active. Not on list yet, but it's 2.5+M. Probably near Quitman.

Abstract and free study. Good find.

Coseismic gravity changes of the 2011 Tohoku-Oki earthquake from satellite gravimetry

Key Points

* GRACE detected coseisimic gravity changes by 2011 Tohoku-Oki earthquake
* The third case that GRACE detected coseisimic gravity changes
* Coseismic gravity change roughly scales with the seismic moment

This quake felt different... a sharp "whack" and then a pretty strong side to side "rocking" feeling.

It lasted long enough for me to get to my desk and do the "drop,cover and hold".

This one felt more like the larger ones earlier this year.

Just an observation.

Unlikely since the magnetic pulse was recorded in Alaska. Incoming in Alaska at that time would not be anywhere near Kermedec either in time or in location. Note that Guam, closer in both Lat and Lon - although not very - shows more or less nothing thus is an indication that the anomaly did not extend that far south.

Just had one in Colombia, near Bogota:

That's the latest quake. The earlier quake has fallen under a desk or something. Yes, the location is the same. The quakes are not on the last swarm's fault. The fault is bigger than thought.

reply to post by Robin Marks


Yes, that is the most recent. Just for giggles, I looked at the depths of the latest swarm of quakes. The recent ones have all been shallow with this last one only at 4 miles. Your thoughts on the depths?

Be Well.

reply to post by Bishop2199


For me this is deja vous all over again. The depths for the Guy/Greenbrier swarm were also shallow. Most, that is. I've written much about what I think is happening. It's injection. Also, check out Arkansas thread for more.

www.abovetopsecret.com...

Hey, they found that earlier quake.

earthquake.usgs.gov...

When you look on google maps. There are half a dozen fracking wells within a one kilometer radius.
This is not just the remnants of the Guy swarm like Scott Ausbrook USGS, said to the press. He failed to note the change in locations.

reply to post by Robin Marks


USGS KML files for 2011 show this:



The red circle is the area of recent activity, the yellow is from around Feb-Mar of this year, the purple quadrilateral shows the expanded area of concern. You are absolutely correct in thinking that the fault is longer than originally thought by the USGS.

Here is the same area with the 2010 data:




Looks like a lot of activity in those two years in a small area.

Did you catch Ira Flatow's comment on your link, about there being an earthquake & hurricane in Connecticut in 1985 when he lived there? The hurricane made landfall in Conn on Sept 27th, but I couldn't pull up an eq for that year. Most of the lists don't go back that far, & I didn't have any luck putting in a search.

I was just about to Google it, but am now having trouble, can't get Google to load??? Was just wondering if that was another eq/hurricane connection? He commented to Diana Romar about it, but she said it was just another amazing coincidence! (Meaning the VA eq & hurricane?) How many coincidences does it take to make a 'light bulb' go on for the 'experts' ???? Hmmm.....

Just had one down in Chile:
