10/01/2013 12:26:59JST (10/01/2013 03:26:59UTC)


not sure about some of the text locations on the tags, the biggest quake is a 4.1 near Niigata on the west coast of Honshu, but the program came up with "Eastern Honshu"
I might have to use the slower Batch Reverse Geocoding and get the actual addresses.
next time

I ran that one through the batch Geocoder to get the addresses, took 7 1/2 minutes to process the 236 lines, not much better either, anything offshore is blank and any Japanese writing is not converted to English by Google Earth, its just put in as ????????.

So I ran it through the FE Regions Finder to get the offshore stuff and combined them.

I have reverted to FE Regions for the locations, will stick with that.

yep found the old Hierro graphs.

I've saved it as a template and adjusted to fit the Japan data.
Its a bit more complicated though as the data I'm mapping here transcends two 24 hour periods and the graph is just 00:00:00 to 23:59:59
So had to make two graphs and stitch them together. Its a bit like doing a search on ANSS for Alaska data where the area transcends the anti-meridian so you have to do two seperate searches to complete the area.
At first glance it doesn't look much different than the numbered 0-271 graph, but if you look closely you will see the lines are slightly different. I've marked on this one the differences.
So this graph is more accurate and at a glance you can see when things were quiet for a period ( the lines stretch out width wise more and the opposite too, when they are compressed there were a lot of quakes in a short period of time..
the two black dots are where the first graph ended and the second one started

just need to add the vertical grid lines and maybe add some more time marks and good to go

Note: disregard the title on that last chart, I forgot to change the templates text there

This is all a work in development

The feed back has been overwhelming ie I don't know why I bother.

Who seen the change of movement to the west over the last few days eh?

thanks for the encouragement lurksoften


I couldn't be bothered last night, but here is the map now anyway

Thank you.

This is great.

I guess I'm becoming kind of an earthquake geek. I learn so much from you all.

Good

Japan is becoming an obsession for me, the more I look into it, the more I want to know.
I'm looking at the various FE regions, (thats the addresses on the tags), at the moment I have no clue as to where the borders are. I have a pdf file somewhere that I'll try and figure out how to convert the vectors to a kml file then I can map them too.
I haven't been putting the TTNT energy released on these files, but its easy enough to do, just add another column.
Then I can add up the energy released for each area during each period.
Like on that last map the areas where;
Eastern Honshu. Japan
Eastern Sea Of Japan
Hokkaido. Japan Region
Kuril Islands
Kyushu. Japan
Near East Coast Of Honshu. Japan
Near S. Coast Of Honshu. Japan
Near S. Coast Of Western Honshu
Near West Coast Of Honshu. Japan
Shikoku. Japan
Western Honshu. Japan

but thats not them all


Its all a bit confusing, because on the NIED reviewed data they have the areas broken down even further into Prefectures.

I've made my first Japan FE region KMZ file, for 228-near the East Coast of Honshu

Took a while, Puterman and I did this for New Zealand about a year ago, but I had forgotten how to do the filling of the polygon and set the opacity.
here is 228-near the East Coast of Honshu
There are 30 FE regions more that fit within the basic map size I do for Japan, once I plot them all I'll group them all into one single file which will come up with one click, similar to the Plate Boundries file.

One name that is missing from the FE lists is "Far off the East Coast of Honshu", that shows on the NIED "reviewed" data, not sure if it is part of 229-off the East Coast of Honshu, or JMA just made it up, from what I have seen on the locations that are marked with this name so far it appears to be the eastern side of the Japan Trench, JMA name events on the western side as "FAR E OFF FUKUSHIMA PREF" or "FAR E OFF SANRIKU" or whatever, but that's a different kettle of fish anyway (the reviewed data)

Ha did another one

227-Eastern Honshu

I was particularly interested to see that one, as I couldn't figure how Niigata ended up as eastern Honshu when it is on the west coast (as per this post on the 10th Jan).
"North and Central Honshu" would have made more sense to me


I won't post any more until I get them all done, should get through it this weekend, Monday is a holiday for us here

interactive map for 17/01/2013 03:01:30 to 18/01/2013 03:55:16UTC
includes this one

Lat/Long: 42.0552 142.7449
UTC: 17/01/2013 05:13:23
JST: 17/01/2013 14:13:23
Depth: 50.6 km
Mag: 5.2 ML
Location: Hokkaido. Japan Region
Energy Released: 951.5 tonnes of TNT

with 9 aftershocks

also the Tonnes of TNT energy released by F_E Region


.................... see where I'm going with this?
obviously a mag 5 pumps the energy out, it takes a lot of 3's to make a 5
9 of those 141 Near East Coast Of Honshu. Japan were 3's, making up the bulk of the TTNT at 17.32TTNT
edit on 18-1-2013 by muzzy because: (no reason given)

I could break it down further and have the columns for each magnitude for each region, need to write some more Excel formulas.
edit on 18-1-2013 by muzzy because: (no reason given)

for those readers not familiar with the conversion of magnitude to Tonnes of TNT energy released here are some examples.

You would think someone would have already done this, but I couldn't find anything that was useable on the Internet.
Exclusive Global Release right here on ATS

KML version of Japans Flinn-Engdahl regions (or F-E regions)
I made 2 versions.
1. Interactive with each region having a different colour 30% opacity, so you can see the map or land form behind. Japan F_E Regions V1.0
2. A simple interactive lined version Japan F_E Regions V2.0


You can save either version to Google Earth by copying the file link address from the Google Maps search bar and paste it into your browser address bar. Providing you already have Google Earth, it should open directly when you click go.

The lined version doesn't stand out very well on Google Earth as the lines are black, but you can easily open the first sub folder and right click Properties/Style,Color on the file and change the lines to whatever colour you want. It looks great on Google Satelitte though

As with all the Google Maps I do you can click or unclick each sub file as you wish. Actually works better with lines than it does with icons.

For readers who have no clue what I'm talking about ....................

The Flinn-Engdahl regions (or F_E regions) are a division of the Earth into seismic zones. In seismology, it is the standard of localizing earthquakes. The scheme was proposed in 1965 by Edward A. Flinn and E. R. Engdahl. The first official definition was published in 1974 and a revision in 1995. Borders of the F-E regions may differ from political boundaries. For instance, the F-E region 545 ("Northern Italy") also includes parts of France, Switzerland, Austria and Slovenia. After the 1995 revision there are 754 F-E regions, subsequently numbered from 1 to 757 with three gaps (172, 299 and 550) at dissolved regions. (wikipedia)


These are the names that appear in the popup tags off each icon on my interactive maps here and elsewhere.
Took me about a day to plot all the polygons, doing one or three here and there as I had time.

Theoretically given time if you search "F_E Regions KML files" on Google, it should bring you back to this page.

The resource I used is an oldish pdf by J.B. Young , B.W. Presgrave, H. Aichele, D.A. Wiens , E.A. Flinn
called "The Flinn-Engdahl Regionalisation Scheme: the 1995 revision}
original copy available here.

Thought I would try something different this evening,
I have always preferred Open Street Map maps, they are clean and easy to read IMO, but unfortunately you cannot create interactive maps with them in the manner that Google Maps offers.
So here is an alternative

A screenshot of the days events in Japan on Open Street Maps.
Click it and it opens (in a new tab/window) the interactive Google Maps version.
As a bonus I have centered that (the interactive Gmap) on the spot mentioned in the comment text below the screenshot
Killed 3 birds with one stone




o/s Choshi finally popped a 5, been watching that peninsula for months now, always a cluster of quakes every day, first time I've seen one that big amongst them (since the 2011 mag 9.0 aftershock sequence)
there.

Actually 4 birds with one stone, I stamped the time period on the screenshot too.


Don't forget you can oom out on the GMap too see all the other events and click on them for the data too.
