Witness location : Lorient (France) (27 km W from epicenter)

Heard noise as though heavy machinery being moved in the building with very slight shaking... Very similar to usual sound of lorry coming at you through the ground that one hears with earthquakes. Had not expected a quake in southern Brittany. Have lived in NZ and felt MANY there, typically mag 4-5 and distant 7 - also (largish ones) in Chile and very small ones in the USA. Other person has since tweeted from south Finisterre about feeling this quake (@CecBres).

Witness location : Melrand (France) (30 km NW from epicenter)

There were only two of us in the house at the time not including the dogs. We both wondered what it was, it felt like a car had driven into the house and a wall had collapsed but that is not really possible where we live. My second guess was that the boiler had blown up, which I promptly went down to the basement to check. Our last guess was an earth tremor.

Any opinions on the two 3.5 quakes RSOE has in Ohio today, or last night I should say. Odd places for them to show up. 8km deep one hour apart in the middle of the forest not too far from each other. New place for a quake. Though not new in the theory world.

They were just one event, RSOE duplication, that is why RSOE is not considered reliable, people get confused by their lack of human processing............

I understand that. Its more the size and location that has me suspicious.

I think it is a case of just learning and understanding what you are looking at. Please don't tell me that the others are much better at disseminating information. USGS are laughable on occasions. There locations are often hopeless and they have a tendency to hide quakes that they claim are not natural.

All it takes is knowing what you are looking at.

Well if USGS are useless then RSOE must be double-useless, because that is where the RSOE data comes from for the USA.

Now some shaking in IRAN

This is a 3.7M quake in Oklahoma. The news was trying to suggest some resignation about the situation by calling it the new normal. Barf. And, they've only pointed at injection as a culprit. The folks in Oklahoma won't be so complacent after they start to damage their homes. And, when they magnitude increase to 4.5 or >.

I'm not going to scare monger, 'cause if you don't see it, then more of me ranting about it won't change a thing.
Something bad is their way a coming.

I checked and there's no lakes to blame for this one. The fracking pad you find on the satellite is just under two kilometers away from the epicenter. Nah, can't be that. Right Masta Holland?

Wait, there's Yost Reservoir. But that's not much more than a pond. And, it's about ten kilometers away from the epicenter. I would have blame that Ohio quake on fracking. But I couldn't find a well. However, there is injection in the Athens area. There's even recently been a public meeting that was held in Athens about fracking and injection. The Youngstown one way back last year were from injection. However, without any proof, I can't say the Ohio earthquake wasn't natural. I suspect it had something to do with drilling. But. What I can prove is that that area of Ohio is prone to earthquakes so there are natural faults and it is stupid to drilling and injection where there is a seismic history and relative risk.

Correction. There is a lake in Stillwater. About six kilos away. I was wondering why the called it Stillwater.

There was also this wee quake nowhere near a lake. There`s a well within 2k.

WOW. I went and checked Volcano Discovery for my daily fix, and guess what I found (my keyboard is messed up and I can`t type a question mark - I get this instead É) É

They`re now covering Oklahoma. What a HootÉ

Too busy to stop and investigate right now so if someone wants to do a bit of sleuthing see if you can identify what caused this

The station Kale is located at Lat 38.3911, Lon 22.1398. There does not seem to be any USGS registered quake nearby on Google Earth. It is showing on some other Greek BBNet seismos. bbnet.gein.noa.gr...

ETA: LAKA also showing strong. Lat 38.2401, Lon 21.9785 and similar activity yesterday:

Thanks. I am busy adding the Greek seismos to the program. Here is an even bigger one from another siesmo for the same quake.

Hi Muzzy, Puterman; with regard to Lake Taupo in above post,

Sorry I've been the proverbial chicken, battening down hatches, monitoring log files and database sizes, and also preparing for AGU conference.

This is a known issue, small regions, but this particular region is somehow unusual and it is throwing off the math for the computation of Z ranges (depth ranges) as regards shading (rear to front) and so forth.

I think I understand now. More below.

As surmised, the work-around was to select a bigger box, the main body of the North island, like this

but even a lesser, but moderately-larger selection fails, like this

In general I think it is that there are a few shallow quakes and then a big empty zone, then all the green and yellow come below that, and the Z range includes the shallow quakes, though they are next to invisible, and then the large empty depth range, making the deep ones "distant" and dark.

Apparently because of the fact that coastline and plates start off being displayed, I'm using depth=0 as one end of the Z range. It makes some sense, X and Y and Z are normally placed at zero. Also most quakes are shallow, one could say "looking at selections with mainly deeper quakes and few shallow/midrange will be problematic".

The logic to compute Z range could still be tweaked to account better for large empty depth ranges and lone outliers like a single, small shallow or deep quake that throws stuff off, regardless of where the axes and coast are drawn, of course. It's just a range. just that it's rather convoluted and I hesitate to change it.

Also, there's this: I have the idea of adding

View / Depth / Compress
View / Depth / Expand

commands to help squash or stretch these "troublesome" views.

If you celebrate Thanksgiving, I don't believe either of you do, well have a nice one!

Have we all given up that we missed this one?

reply to post by rosswellian

No it doesn't seem to work for small areas does it.
Maybe with a narrower band latitude wise?

reply to post by PuterMan

Although GFZ archive their graphs I don't care for them much, a bit unsure about the hour breakdown, there are no axis lines for that, and the traces are a bit thick.
I think IRIS are doing the best graphs
Here is the same station on the same day on IRIS
www.iris.edu...

The quakes seem earlier than the GFZ official graph, whats up with that?

confusing
