I feel a M6 for NZ coming on.
data shows a pre-M5 low of energy released of 8TTNT the last 24 hours, very low.

No word on the Possible Tsunami on the east coast, 6.8 off the east coast?

sorry for the informal structure, but my boss just informed me of this and I'm a bit surprised and freaked out.

EDIT: I cant find anything on it sorry, I was looking for a link. I did see it on her phone though....hmm, sorry if I was wrong and posted too soon everybody...

a reply to: GoShredAK
doubt it, needs to be over M7.5 to cause anything significant from that distance

US say 6.8Mi, still building the page by the look of it, on conversion to Mw likely will come down

Thank you Muzzy, I appreciate it, whew... seemed like doom potential to me for a sec.

yikes

a reply to: berkeleygal

So there were two before the 6.9, Possibly relieved some pressure and the 6.9 will be the final and biggest quake for now?

a reply to: berkeleygal

so it went up on conversion!, that's unusual i think, will have to check on some other big quakes, Wilbur should have them with Mi.
early days yet, 7 days will give a better indication of how big it actually was.

gfz confirm 6.9 on conversion to Mw
emsc have 6.8mb
www.emsc-csem.org...

been 3 months since the last M7, Molucca Sea 15/11/2014

USGS now 7.1Mww, 7.0Mwc, 6.9Mwc, 6.9Mo
and GFZ 7.0Mw


I had a look back to the last few M7's in 2014 on Wilber and the Mo tends to be less than the Mw. Mo is consistantly show on IRIS Wilber, Me not always.

The seismic moment is a measure of the total amount of energy that is transformed during an earthquake.
Usually only 1-10 percent or less of an earthquake's total energy is released in the form of radiated seismic waves.
so 7.1 Mw =
Seismic Moment = 13,164,619,895.0 Tons of TNT
Radiated Energy = 673,609.7 Tons of TNT

Where ever in the past I have quoted TTNT, e.g. on my Interactive Maps it is Radiated Energy

whatever, it was a powerful quake
and rare for this spot, only 5 others in the last 100 years, max M7.0, 58 years ago 13/2/1967

That North Mid Atlantic Ridge M7.0 has got me going again on the M7+ project, I need to start 2015 now.
With the Google changes at the end of Feb, the maps are about to go blank, making the whole thing totally useless.
I've been playing around with Open Street Map.
Its not quite the same, without the custom icons the maps look quite different and I am having trouble getting the popup tags to show the data in lines. Also getting the map to show with the right centre so all the icons show on it has taken me a couple of hours. There is a bit of experimenting to do yet, but I think I can redo the whole thing. Biggest task will be the text on some of the popups, they are not in the CSV files I created, the text was added in Google Earth as KMZ, so having to use KMl I'll have to go through each year and grab the text of each individual event (that has extra text) and copy and paste that in the CSV file.
Due to Wordpress only allowing Google i-frames, the project will have to be transfered to Blogger, which accepts all kinds of HTML.

See what you think, feed back would be welcome, I did a test page, of the year 1997

here's a screenshot to show what it looks like


the original M7+ project is in my signature, but for those that are not logged in here it is again

*the W8 type pesky popout menu on the right side is a real PITA, it goes over the menu bar and you can't move the bar. If you read the single page off the main home page its not a problem though.

a reply to: muzzy

It is also on a spreading ridge not a subduction zone so not likely to cause a tsunami.

There have only been 2 there in the last 20 years (500 mile radius of the event today)

The link goes to my post because the link would not work but it does work from that post.

a reply to: muzzy
or could go this style, with pins, easier to see the icons?
The pins actually "penetrate" the map where the location is, unlike the ones I experimented with at Christmas.
A little bit more work as I have to change the colour individually, OSM doesn't recognize colour in the CSV file.


On the 1997 page, the text list has events that have more information highlighted in blue, this presumes the reader has some geographical knowledge to be able to find the pin on the map, in the case of 1997 where Iran, Kamchatka and Tonga are.

the project link again in classic view. As it builds Flipcard becomes the best view, as you can see all the maps and be able to select whichever one you are interested in from there. Flipcard will be the default view when you first arrive at the blog.

had one in Queensland, Australia (around 400-500 klm from me) earlier this morning, was between 5.2 and 5.4 and the 4th in the area in less than a week.

that's pretty big for Queensland!
there's some kind of Gold Mining operation 39km to the east, south of Perry
