Quake Watch 2011

reply to post by BobAthome


Yeah I could maybe create my own wiggles and put them on a chart as an image
I'm half way there with the timeline graph I do now using coloured dots
I'll have a go
I have the data on csv Excel file already (used for the maps)

example

Another big aftershock 2hrs ago at the Kermadecs, 5.7 Mw ....................... (5.5mb on the phase data)
earthquake.usgs.gov...
So why aren't the other 5.5mb' quakes converted inti Mw too?

Looks like selective data manipulation on the USGS Last 7 Days list, to make things look worse than they really are.
If they were all in mb it would be a flat band of aftershocks between 4.7 and 5.6

Yes I think I have seen negative magnitudes before, was it the Iceland site?

Yes it was, heres an example

Also on NORSAR, the Norweign Seismic Array lists
heres an example , negative magnitudes are quite common, look for the "Netmag"

heres where you get the lists, they are numbered from 1-365, today is day 190 UTC

these guys are so precise I wouldn't be surprised if the negitive ones weren't Whale Burps

ahhhhh punch cards lol thats a lot of holes

You know it might indicate stress build up,,not stress release,, kind of a "potential energy" wave.Being in the negative that is.


Me Guessing.

Big bump off Japan. Somebody was talking about the region off New Zealand as being busy. I was noticing that as well, and was expecting something there, not Japan. No tsunami warning I think.

Yes they are a regular feature on the Icelandic lists.

Negative magnitudes are still quite substantial! (as a meal?)

We have 3 or 4 threads started on the
Japan quake. There is a tsunami warning
and the Fukushima plant has been evacuated.
Hope for the people of Japan!

If you are suggesting what I think you are suggesting then you should not be suggesting what I think you are suggesting. Just suggesting!

After three weeks of being without my program, my graphing and earthquake lists etc I FINALLY got it all back and working today and the first run I see the 7.0 - a big red blob!

Not wholly unexpected however. Has anyone accessed the Japan Met Office tsunami bulletin yet?

Ha! We'll see in a few days if what I wasn't suggesting happens.

I got a bad feeling.

That is a song title isn't it? It won't happen. It has never happened before in recorded earthquake history and I see no reason why it should happen now.

As I have stated before a 7 to 7.5 was on the cards but and 8 or greater was not UNLESS Japan was not going to run to the 'norm' (if there is such a thing) whereby very large quakes only follow very large quakes in Indonesia and Alaska, and usually not within less than a one year period.

To get a 9 so soon after a 9 would be like winning the Euromillions! (Lottery) 116,531,800 to 1

Meteorologists warned of a possible tsunami of around 50cm (20in). But NHK reported an actual height of just 10cm (4in) for the surge.

There were no immediate reports of injuries or damage, according to NHK.

TBH, was this mag really a surprise in the aftershock sequence?

JMA have now cancelled all tsunami warnings:

edit on 9-7-2011 by berkeleygal because: (no reason given)

And dont forget:

At 9:46 PM Pacific Standard Time on March 10, an earthquake with preliminary magnitude 7.9 occurred near the east coast of Honshu, Japan . (Refer to the United States Geological Survey for official earthquake parameters.)
IF TSUNAMI WAVES IMPACT HAWAII THE ESTIMATED EARLIEST ARRIVAL OF

MESSAGES WILL BE ISSUED HOURLY OR SOONER AS CONDITIONS WARRANT.

Thanks for the comparison. I see the depth of both
quakes are close to the same. I certainly hope they
are not in for a bigger quake this time around.

I could be wrong but I don't believe there have ever been two 9.0+ mag quakes in the same year in recorded history, let alone a few months apart.

So if that were to happen in Japan, or anywhere else it will certainly add plenty of fuel to the 2012 and other doomsday prophecies.

Also if Japan were to get rocked yet again and 'sink into the ocean' like many psychics (i.e. Edgar Cayce) claim will happen that will be the last sign I need to personally see we are truly living in the end times.

Wow just saw this pop up on the android app too.

This is directly under the land mass underneath Toyko, pretty shallow too so it's not likely an aftershock from the earlier 7.0 quake that was in the ocean.

Stay tuned.,....

I see that the Russians are quite high on their reading for the o/s Honshu quake
7.3Ms and 7.1mb

USGS are only 6.8mb
Geofon 6.9Mw
EMSC 7.1Mw

if it wasn't for the Russians I think this one was likely for a downgrade below 7.0
