Quake Watch 2015

I'm just thinking out-loud. There has been three >3 magnitude earthquakes in northwestern Nevada. The ones listed on the USGS as being closest to Lakeview, Oregon. In the past I have stated that there is a connection with these quakes and those that have been reoccurring in Idaho.

So, at the moment there is nothing on the Idaho front. If the quakes are connected, there should be something in Idaho really soon. Hmmm. I've been trying to ignore any news on the ongoing swarm in Nevada, because I do that from time to time. Try to forget, by remembering to ignore. But I can only go so far. I need to see the the scientist think about the swarm. In all honesty, I know I will find whatever they have to say about it, it will be non-committal.

To update, there have four >3M in northern Nevada. 19 earthquakes in total for the day when you include the tiny ones.

not a major one, but caught my eye on Geofon last night where they had it as 4.2Mw
now changed down to 3.9Mw

5 others in the swarm

Well now, that Idaho quake was right on schedule. I am very excited because this proves my hypothesis. I was able to accurately able to predict. But the mystery is not solved. This only prove there is a connection between the Nevada swarm and Idaho. One could argue that it is sympathetic stress from tectonic forces. There is a study which suggests that inter-continental earthquakes are different from coastal. To make the point brief, earthquakes in one part of the continent can squeeze and stress other parts causing earthquakes in nearby zones. Like people bumping around in a crowded elevator. This is not my belief. It's possible. But we're talking nearly 1000km of influence. I think not.

I think this is a fluid thing. Hence, the delay. That's the moving fluid. By following the quakes, you can follow the movement.

Next, it may be right to keep watching Yeller' to see if the staled uplift changes, and or, there are any vigorous swarms. There have been swarms. But very small. That Boiling River story had me thinking. But I don't think there has to be more than just a normal flucuation to explain that one. What do I know?

West of Kuharua volcanic cone, 15 km north-west of Turangi, SE corner of Lake Taupo (volcano)
34 quake swarm, 32 of them in 24 hours, all small though, 5-12km deep, most at 7-8km
Largest was a M2.44 but it was the 9th in the swarm.

Not sure what that was about
there have been swarms in this general area before, but a tad south of Kuharua, some real big ones, I'd send you the link to those but its busted thanks to Google Maps now.

further to: muzzy
I knew there was something familiar about this small series, but couldn't recall, south of Florence.

here it is, this last lot was a bit to the west of the earlier swarm

At the time (07:00 of March 4, 2015) are more than 530 earthquakes occurred in this area since December 18, 2014, the majority of which are of a magnitude less than 3.0, and a single event that has reached magnitude 4.1 on December 19 at 11:36 hours .

Can anyone here have a look at NZ EQ 2015 for me and tell me if the NZ Topo Maps are working?

I'm getting
HTTP Error 404 - File or directory not found.
Internet Information Services (IIS)

this is genuine request, I'm not fishing for readers.

It may just be a temporary thing, or it could be Google has sabotaged NZ Topo as well as everyone else.

The show must go on, therefore I have done 05.03.2015 on OSM
what do you think? I can't get colours, but I can get labels.

OMG if NZ Topo is out of action .................

how many times do I have to redo these files?

Being the pessimist I am, I've set up Japan on OSM as well just now

the more I do of these the better I like it, just got to get over the lack of magnitude colouring.
Japan is a bit different to NZ however, as we have both preliminary/automatic and reviewed rolling over every 2-3 days
what I may do is change the colours of those, such as green for reviewed and gray for automatic
japanquakes.blogspot.co.nz...

Never mind, its back on.
What a shambles.

This morning there was one 2.5 M earthquake in Northern Nevada. I am thinking this should set off an Idaho quake. But I don't know. Since we had four +2.5M the day before yesterday, this may be a left over. And, if so, this may not mean an Idaho earthquake. When the "Lakeview" (I'll call them that since the USGS keeps listing Lakeview Oregon as the nearest main city) +2.5M come as singles, they can set off a single Idaho quake. But like I said, this cluster was slightly more vigorous and this quake may not get a reply from Idaho.

Sorry to go on ...........
This is a mapping crisis in process, what to do?, which map system? which is most reliable?
NZ Topo maps has some issues, especially when it comes to putting out Japan data, as mentioned previously.
I'm going to go with OSM for Japan.
I have written a Navigation Guide for those new to OSM (like myself)
I just discovered how to use the "browse data" menu, handy if you want to find the biggest quake, OSM automatically lists them in size smallest to largest. You can do as described on the daily page too, but the menu shows below the map, it is better to go "view full screen".
Navigation page
I could manually change the colour of the icons one by one, but that is way too much work, especially if there are a lot of M3's, and I would have to set the limit to M2+ as there are too many 1's and 2's per day to split them by colour.
Thank you for your patience.

I've done a trial for NZ too, 5th and 6th March

Will see how it goes, already doubled the readers in 2 consecutive days!

edit: maybe there is a whole bunch of people who are interested in earthquakes and who are colour blind!
and prefer pins to circles

question: can you see the circles in B&W?, never thought of that.

another flurry of quakes at Kuharua, W of Turangi and SW of Lake Taupo
all less than 2.81
most are 1's except that 2.81 and a 2.34

I've been wrong before, but it works most of the time
TTNT count for NZ yesterday was 8, below the Muzzys Rule threshold of 10, a warning for Mag 5+ coming to NZ.

The next thing I look for is, anything to the SW on the Pacific-Antarctic Ridge?
Yep
Its a small one, but there is movement down there

right in the middle of the Los Santos Earthquake Zone, its a mining area, gets 400-500 earthquakes a month average, M1-M5. I'd send ya to the Columbian interactive maps I made but Google terminated the operation in Feb.

Forgive my intrusion here please. I hope the following makes sense to you.

A 5mag has just occurred on the Atlantic ridge across from mid-northern South America at a depth of 10 km. I have always been under the impression that expansion at the ridge is a constant. However I am trying to figure out why the 10 km depth and why such a high magnitude in the ridge itself. Does this indicate that there's a high degree of resistance from the plates to the east and west themselves? Or that at that depth it's just about splitting a hard rock or two at that ridge location itself?

Is my thinking wrong about that? Is 10 km a magic number of sorts across the planet, as many quakes seem to happen at that depth?

Thanks for your replies.

a reply to: aboutface

10km is a default depth, as is 33km, you see it on many networks at those depths (GFZ, EMSC, LDEO, and GSRAS for example)
The USGS tend to try and get more accurate depths if possible.
No answer to the other question really, a M5 quake is a decent size, in subduction an earthquake is the release of a piece of plate that has become snagged, may be different in the spreading situation, or maybe its the same.

this small swarm is still going on, maybe this gif animation might show something, maybe not

here is the full series so far cumulative (one image) 111 earthquakes

wooohoooo
major breakthrough using Open Street Maps (OSM) for plotting earthquakes.

the issue for me has not being able to show the magnitudes by colour, on OSM if you load a KML file all the icons are the same colour.
Just figured out how its done
by adding layers. doh!
The only down side is the daily KML has to be split back at the Excell CSV stage and a KML created for each magnitude.
But it works!
I have done Japan 13.03.2015 for a starter. This file is a combination of JMA and NIED data, so is not final yet.
Japan 13.03.2015
here are a couple of screenshots of how it looks in various formats i.e. overview, without tags, with tags


and another advantage of splitting the files is that you can turn on and off whichever magnitude you like, so the people who can't be bothered with the M1s and M2s can turn them off if they want to.
This SS show just the M3's and M4's for the 13th

I guess I could split it into JMA and NIED files too and show those as different coloured icons if there was a need.
I have kept the magnitude colours as close as I can to my old colour scheme, although they are a little darker, OSM icons show quite brightly in the lighter colours, which saturate the ball on top of the pins, and hence don't show as 3D.
I've written up navigation instructions with a new icon key and put it on the Navigation page of the blog.
Japan OSM Navigation
NZ upgrade will follow later today.
The trouble with OSM and Umap is that there are basically no instructions on how to use it, you have to figure it out yourself.
