Google Earth mapping of the last 365 days of quakes 4.5+

Thought some of you folks might be interested in this:

I have been working many many long hours of toil on the new version of QVS Data (formerly Quake Data) and crafting imports for USGS, EMSC and New Zealand (GeoNet) and part of this is comparing locations of quakes to see if they are the same. This is actually more difficult than it sounds - one of these situations where a human can interpret information more easily than a computer.

Each degree of latitude is about 111 Km on the ground. GeoNet use 5 decimal places, USGS use 4 decimal places and EMSC and Iceland use 2 decimal places. (Published information. Their own records may be more accurate)

What does this do to placement on the ground?

[atsimg]http://files.abovetopsecret.com/images/member/602d02ab625a.png[/atsimg]

As you can see NZ ROOLS!! GeoNet is max 740 mm out against 740 metres (1000x worse) for EMSC.

Longitude is a bit different as the distance between degress of longitude depends on where you are in terms of latitude.

On Earth, the length of an arcdegree of north–south latitude difference is about 60 nautical miles, 111 kilometres or 69 statute miles at any latitude.

The length of an arcdegree of east-west longitude difference is about the same at the equator as the north-south, reducing to zero at the poles.

Us Kiwis like to know exactly where we are.

could be an insecurity issue

Ummmm.... is this anything to be concerned about???

Checked the local papers for yesterday and there was a small report in "www.republikein.com.na" in Afrikaans which I can translate if anyone is interested. What it does say is that the tremor was reported to the paper by various people but most said it was just a trembling of the ground underfoot. What is interesting to me though is that the friend who felt says it was definitely around 4.10-4.15 and the paper is reporting it to have been around 3.45pm.
Reports of dogs barking and birds flying out of trees but no damage or injuries!
Thanks for the info Puterman!

ps. I got the name of the extinct volcano incorrect it is called "Brukaros" or Brucharos" and not Mukarob (The Finger of God) which is another natural landmark in the same area!
I should concentrate more when typing and not let the moment take hold causing such errors! My bad!

Another quick ps. I have heard today that it registered around 2.5, just a baby!

BANGLADESH... very rare.

Yes rare indeed.

I don't understand completely yet what the theory is, but some pundits out there think that the P-wave shadow zone is sometimes a warning of where near future quakes will occur ( especially after big quakes like the Christchurch 7.1)
Here is the P-wave map for that quake, and what do you know, right there on the 103 line is ..... taadaa Bangladesh

and also on the 103 line today is ...................
Peru- Equador 5.1
and o/s Salvador 4.7



Worth following, see how many quakes have been within the shadow zone since compared tho outside

followup to post by muzzy

OK.
I transposed the boxes off the Recent Worldwide 7 days USGS Map onto that P-wave map to see whatsup

No the theory doesn't stack up , the quakes are where they always are ...... all over the place

Hey you guys, jump over to the Yellowstone thread!!! Things are heating up.

I realize the two 4.0 are south of the park, but check out the seismos....THUMBNAILS

Jeepers - that doesn't look too good... something else to watch - I'm still being bombarded with aftershocks here - Monday morning and the bloomin' things woke me up again (

reply to post by MoorfNZ


WOW....I have been looking at more pics from your area and it is absolutely amazing. Your stress level must be at an all-time high!

Not to be negative or anything, but I still have this feeling that things are building....perhaps that is a stupid statement as I supose you could argue that it is ALWAYS building to a realease. Maybe a more accurate way to explain it would be that it is speeding up?

reply to post by westcoast


Don't worry, I also believe that this isn't going to follow the "normal" pattern they keep subscribing too.. don't know why.. perhaps it's my mind's way of coping, afterall I'm a total pessimist!

reply to post by westcoast


Boring old soul that I am, I am thinking this is nothing to be getting excited about. When all is said and done it is only 33 miles from the little swarm in August, so I guess this is probably just an adjustment as a result of that.
