Quake Watch 2011

That blue squiggle is the 6.4 in Fiji I guess since that popped off at 11 minutes past midnight

Is Fiji being activated by the fault off of Honshu?

I've looked back through my QuakeFeed app and note five consecutive occurrences of a quake in the Honshu region followed by one in Fiji within an hour's time-frame. Obviously not ever quake in Honshu triggers Fiji, but for the past 5 occurrences for Fiji there is a quake up north within an hour previous.

I know this would be similar to pulling a few straws out of a bale and comparing them to one a other, but I am wondering if there is a pattern to the amount of activity in Honshu in relation to the activity in Fiji.

Whilst I could not deny a possibility I would have to say the in my opinion the distance of 7000 km is too great to be getting a triggering effect.

The white line next to Tonga is the trench and the other white line is the run of quakes at depth. These are all over 300km deep. If we are to believe subduction theory then it would suggest that, since the earthquakes at shallower levels that are occurring after the deep ones for the most part, they are being caused by a bit of slab pull, or maybe a bit of push, anyway it seems reasonable to think that these might be the result of 'normal' tectonic processes in the area.

I'd tend to go with Geonet's location.
Seldom are they more than 1km out.
I used to go back and update revisions months later and noticed that as well as there being double to triple the number of quakes on the day, there were not many location changes more than by a few hundred meters.

I see you are looking at the "Bigger Picture" which is good.

But my take on it is that both Honshu and Fiji events are the result of the same cause, rather than one being the cause of the other.

ie expansion of the Pacific Plate ( and possibly expansion of the whole of the Earth itself)

Both situations have Subduction characteristics, so include subduction in the Expanding Earth theory IMO.

Don't forget Chile hasn't stopped moving either, on the other side.


I think this quake www.abovetopsecret.com... off the East Coast of the North Island is related to the Fiji quakes too, as the Pacific Plate dives under the Australian Plate at Fiji and a chunck falls off into the Earths core, it pulls away from out further east somewhere.
Just a theory, we have no models of the style of faulting for the quake out on the Whenuanuipapa Plain.

I have seen a bit of the expanding earth theory and find it quite intriguing especially seeing it applied to mars as well.

I try to "zoom out" and take a wide perspective when viewing and thinking about these issues as it makes mch more sense than drilling down to details without looking up to see that what you are studying is part of a larger whole.

Thank you, and Puterman, for your thoughts.

Checked ATS and cant see that this subject has been posted...but hey!! (Be nice if results came up in descending order!)

Came across this on my newspage today .

A European spacecraft has mapped the Earth's gravity with unrivalled precision - a feat that may ultimately help scientists predict earthquakes.

Gravity tracking for Earthquakes


ETA again....There is a video at the site showing the results. I cant decipher them but all looks interesting!

I posted a video of movement today in Arkansas on youtube and on the Arkansas thread earlier. Someone commented back on the geomagnetism being off today too and posted this link to me on youtube.

Could it be playing a part here on most everything going down today. I know I have really rotten all day, ears ringing horribly with my right is in piercing at times, headache and nausea again. We also have rain coming in again and it's been misting most of the day.

I have been watching seismic monitoring below Vancouver Island (3 southern most stations) and I have noticed something that I have never seen before. I wanted to place it into this thread because I know I will get a valid answer. Thanks.

If someone could explain, namely the past few hours (if not the whole graph) What am I seeing? Magma movement? Interference?

Umm yep, be happy to explain: basically IRIS has been down most of the day, and just came back up (mostly) hours ago. All kinds of networks were (and some still are) having problems. They often manifest as the dropouts you see there, in addition to making the webicorders like you have there do strange things.

In a nutshell, it is just normal (for when a major network like IRIS has serious trouble). And today they did, for sure.

sorry if already posted but I am in work and only just heard on the radio that there was a small quake in Blackpool here in England around 03:30 this morning. It only measured around 2.2 but thought I would add it as quakes are rare in the uk and it adds to the bigger picture of quakes around the world

I've decided I would like to contribute to this thread, an area that I have been intently following this month. This image is an overlay of Earthquake activity/faults and "Known" Volcanic Ranges/fields in Western Canada. Since USGS rarely covers the smaller rumblings that we feel/see on a day to day basis here. Since the whole world seems to be having an up-kick in activity, its worth keeping an eye on.

Check out the website if you want an actual magnitude of these quakes. None are above 5.0. Now what I find to be the most interesting is the activity in the Wells Gray Volcanic Field, particularly across the border in Alberta. While BC (as you can see) is geologically shaped by faults/volcanic ranges... Alberta is a vast prairie...

"Since the first recording stations were set up in 1918, the Geological Survey of Canada and the Alberta Geological Survey have recorded 918 earthquakes ranging from magnitude 1 to magnitude 3," says geophysics professor Dave Eaton, head of the geophysics department at the University of Calgary. "A magnitude 3 quake would have about the same effect as a heavy truck rumbling past the house, says Eaton."

Just a question. I noticed two new threads about earthquakes happening around the world. Why are they making new threads and not posting here.???

Hmm,.
4.1 in Wyoming,. near Yellowstone?

didadoubler,.oops

one just hit greece

OK it was about 4 weeks late and 0.5 under what I expected, but it finally happened.

I have been watching this area for months and very roughly every three years there is a bigger quake - and the three years was up in Feb.

Edit: Of course USGS have it just UNDER the 6.0!

reply to post by crappiekat


Generally in this thread we would probably expect to see a new thread for a quake for 6+ depending on the area, in other words in one area a 6+ may not be anything unusual, and in another it may be.

Others who are not familiar with earthquakes will not make this distinction, and a 6 is a big quake.

It is inevitable I am afraid!

Hi all, I am quite new on ATS, so I can't make a new topic, but for all you earthquake boffins, here are some news about an "earthquake swarm" in my old home-country, South Africa. Maybe this article can help somebody looking for new information to formulate a theory or to fill in some gaps :
