No Tsunami eh

Might as well use up some of those stars


JMA Intensity maps of todays Mag 7.4 Japan quake



for those that didn't save the pdf file of the comparison between JMA intensities and Modified Mercelli (and others) heres a link to a Gif of that.

JMA VI upper = MMX
geez that must have caused some further damage



MM X. Cracked ground, especially when loose and wet, up to widths of several inches; fissures up to a yard in width ran parallel to canal and stream banks. Landslides considerable from river banks and steep coasts. Shifted sand and mud horizontally on beaches and flat land. Changed level of water in wells. Threw water on banks of canals, lakes, rivers, etc. Damage serious to dams, dikes, embankments. Severe to well-build wooden structures and bridges, some destroyed. Developed dangerous cracks in excellent brick walls. Destroyed most masonry and frame structures, also their foundations. Bent railroad rails slightly. Tore apart, or crushed endwise, pipe lines buried in earth. Open cracks and broad wavy folds in cement pavements and asphalt road surfaces.

I am afraid that while that 7.1 was an aftershock it may also be a foreshock.


That is possible:


The epicenter and focal-depth of the April 7 earthquake are consistent with the event having occurred very close to the main interface thrust-fault of the subduction zone plate boundary. Preliminary focal-mechanisms, however, imply slip on a fault with steeper dip than that of the main interface thrust-fault, which may imply an intraplate source is more likely.


earthquake.usgs.gov...

So what they are saying is that it could be a different source than the original fault. Either that or the dip angle is increasing at that particular point of the plate subduction. The depth of 49 km would tend to corroborate that somewhat, as it is deeper than most of the others which were in the 0 to 35 km range. But if it is a different source, then yeah, that could be a foreshock.

Update of the Live Internet Seismic Server @ of April 7, 2011 - 14:35:00 MDT

Live Seismogram Feeds

I noticed how this site was down for a duration and now they come back online just to show massive amounts of activity on every single Seismogram??

Can someone explain if this might be tremors or something from the recent Japan Earthquakes?? Here are the quakes that hit Japan Today(April 7, 2011):

Sasu, Japan - 4/7/2011 11:48:23 4.6, 47km
Niiyamahama, Miyagi-ken, Japan - 4/7/2011 14:32:00 7.1, 40km
Niiyamahama, Japan - 4/7/2011 06:34:24 4.6, 33km
Shuku, Japan - 4/7/2011 02:40:50 4.9, 60km
Ena, Japan - 4/7/2011 19:11:12 4.9, 30km
Ena, Japan - 4/7/2011 19:11:12 4.9, 30km
Node, Japan - 4/7/2011 10:52:15 4.7, 62km

I think you all know well enough to know that I have pure motives. I rage against those in power and not at those that are trying to learn. I will never demean to inform. But at the moment I am under stress which makes me feel like a cage animal so I am howling and pacing, and ready to bite anyone poking their fingers throught the bars that hold me.

The concept of foreshock, mainshock and aftershock makes me crazy. Don't think of it this way. It's a process. Even the giant locked fault off Washington State is moving. Just incredibly slowly, and eventually it will speed up in dramatic fashion. The plate has been moving forever. At least in terms of human history. And it will won't stop until forever. At least to us. The best way to look at it is like a slow motion car crash spread out of millions of years. All the plates are careenig around like a bunch of vehciles spinning out on ice. Just in slow motion.

I really doubt were going to get another giant quake like on March 11th. And that's pretty certain since most giant quakes don't have double events. Of course there are exceptions. And these are mainly the mid-continental quakes.

I know the media and even geologists refer to the aftershocks and this is how I learned to think of it. If you ever listen to the geologists during interviews they just repeat the same basic information over and over again. Frankly, I'm usually very bored by it now. The media asks the same questions everytime there is an earthquake. It seems like they have perpetual amnesia. I know this is to inform viewers, but it's so rote that I think we're missing the bigger picture. Because they drop the stories as soon as there's nothing new and carry on. What about really taking the information learned and starting to apply it to the real problems that are forgetten as soon as the story drops from the headlines. Where's ongoing investigative reporting on the conditions of the nuclear plants near the New Madrid? Are these plants safe? What are they doing to ensure they are safe? Are the buildings in the region safe? What are they doing to retro-fit and prepare?

I am glad the US Government is taking this threat seriously. There is a real effort to inform the public happening right now. That ought to tell you something.

I just know when Japan recovers in the future, and when the headlines stop being so alarming, I know we'll forget everything we've learned. We'll be chasing Charlie or the Balloon Boy or watching Kristie fall. We're a bunch of jackasses. There's so much real stuff to concern ourselves with.

There is a pattern to the earthquakes. Geologists won't predict exactly. They'll give you odds. And they want to learn so the can predict precisely. I have watch earthquakes closely for a couple of years now and I see so many patterns. All the time. After awhile you stop looking at each quake individually and you can see the world moving. Pulsing. Beating. Like a freaking heart. There is no forebeat in our hearts. The is no afterbeating. Our hearts start beating at a point in time and continues til we drop. Our planet beats just like a heart. The earthquakes are just the bones cracking as we move about, like lungs that expanding and contracting.


Earthquakes are clustered. And each earthquake acts in a unique and complex way with other tetonic plates. It's like a great big waltz. Well, that's the way I look at it when I'm feeling romantic. When I'm grumping and gruff it's like a big smash up derby.

Sorry. It's either write here, or find some dynamite and blow stuff up. Since I'm basically a passivist. I guess your stuck with me.

Yes that is the 7.1 in Japan showing round the world.

you reckon


Care to explain ?

I've been watching quakes for 5 years, 4 yrs globally, I haven't seen any patterns whatsoever.
Everything is random IMO

edit: I agree with the other stuff you said.about the MSM and how soon people forget

HIA (Hailar, China) and GRGR (Grenville, Grenada) are showing the most saturation on LISS

Hailar I can understand, but Grenada
its on the other side of the World


BBGH (Gun Hill, Barbados) is pretty black too

just realised why the map images are different sizes


the bit on the bottom of 2 of them explaining the triangle stations is missing on the other 2. I can fix that

Weird as well when I look at the quackquery version GRGR.CU.00.LHZ.2011.097 it does not even show at 14:00 + hours


Your favourite shows it OK. SNZO.IU.00.BHZ.2011.097

And what about Turkey

????

Compare it to LISS on the 9th March Mag 7.2

Looks like everywhere on the Pacific Plate registered a double-tap and locations on the Australian plate had just the one pulse...

Not sure what was going on there with Grenada and Barbados, now they show a pretty standard Mag 7 page for that distance.

Thats a Swarm
I see no pattern time wise, depth looks pretty consistant.
Maybe there is one location wise, but you would have to map those out at a closer scale than what USGS have on the associated map to that page link.

What pattern do you see ?

I have just come across this page on USGS with regard to the Tohoku earthquake and thought it might be of interest. I am not sure how often it is updated.

Aftershock Map Tohoku Earthquake

As usual you can get daily updates of earthquake numbers and graphs, and KMZ file from here and this page is generally updated daily at around 1:30 AM BST (12:30 AM UTC) but sometimes it does not happen. Unlike some I am not infallible


This page will be moving shortly to the new earthquake related blog in the 'set'

I know that there is a lot of attention on a lot of different faults in the world right now, but I was curious if the fine experts on here could help me out with what is probably just a very simple thing. The reason I am asking, is that I actually have a e-pen-pal friend on missionary work in this area and she e-mailed me yesterday that her nerves are still rattled from the quake this week. Looking at the siesmic history for this area, the quake this week was larger than any since 1990, and I can't find any aftershocks since that 6.5.

So, why no aftershocks here? Thanks in advance.

Basically the deeper the quake the less likely it is that there will be aftershocks. At 167 km deep that one is well into the intermediate zone. I notice there is a 4.3 2 days before that is not too far away and that was at 63 km

Peeps might find this fascinating, especially the visualisation.

Thank you, I appreciate the explanation a whole lot.

So, the more shallow, the more of a chance of aftershocks...makes sense.
