That should be

we switched back Sunday night
forgot to change the template for my NZ earthquakes

regarding that Tonga/Samoa quake
GFZ finally came up with 6.4Mw. geofon.gfz-potsdam.de...

but why is UselesSGS still showing mb?
earthquake.usgs.gov...
shows 5.8mb

Mw is available on their site however
earthquake.usgs.gov...
6.3, 6.4, 6.2 depending on what Mw suffix you want to use, w, b or c

guess it makes things look less disturbing,
2 M6's in 6 days should be of concern, especially as this spot has had a couple of M8's recently
M8.0
Date: April 07, 1995 22:06:56 UTC
Depth: 21.20 km (13.17 mi)
M8.0
Date: May 03, 2006 15:26:40 UTC
Depth: 55.00 km (34.18 mi)
M8.1
Date: September 29, 2009 17:48:10 UTC (major Tsunami)
Depth: 18.00 km (11.18 mi)

FWIW GeoAus are hanging with Mwp (another suffix) at 6.53!!
www.ga.gov.au...

and the Russians at 6.0Ms and 6.2mb

now you have all the facts to come to an educated conclusion

Been struggling to find a suitable replacement for Google Classic Maps which would show the KMZ?KML files for the M7+ project.
I think I have it for World size map, ikimaps to create it and Bing to show it.
I quite like the 3D effect of the Bing map at that zoom out level, its clean and simple, without too much junk (labels).
Seems to work just as well as Google Classic Maps did.
If I'm going to have to redo 104 years worth of mapping I thought I might as well include magnitude down to 6.5, which I mentioned I was thinking about last year.
It eliminates any controversy about the 6.9-7.0 bridge and also takes in a few quite seriously damaging 6's.
I have done 1995 as a test,
and another new filter is that I have all but eliminated the "unknown" magnitude, especially where it was the only magnitude type in the data. At this stage I'm processing the Centennial Data, I think anything that was M6.5 up would be in there. After 2000 though I'll have to wing it.
here is a screenshot of what the new layout looks like.

Japan fears big earthquake after beaching 150 Dolphins...
simulair happend by the big tsunami one in 2011
and at churchville a coupple of day's before the quake...
Dutch MSM now

Balderdash!
What about the thousands of Dolphins and Whales that stranded and there was no big earthquake, over the years.
There were no strandings before the Cook Strait quakes of 2013, or Eketahuna 2014, or the Dusky Sound 2009, none at all.
Group strandings are seasonal.

People forget things that don't fit the sensationalist agenda, ie sell newspapers (and web news)
EnglishTranslation here
It is more likely they died from living in a contaminated sea.

While I had the Translater open, I converted Balderdash to Dutch = onzin and translated back to English = no sense
also known as BS.

I changed the bars to Green, easier to see the text
more here
its a slow process doing the new maps, I'm only getting through one year per day, takes some time to add all the text about the quake in each icon/event.

Are you watching Japan now.

Got a few larger quakes.

Just had a very large sharp jolt in Los Angeles Just now at 9:20 pm

Yeah I heard on the radio in the UK about a tremor /mini earthquake in LA, according to the LA times it was a 3.5, hopefully this isn't a little one before a big one
www.latimes.com...

Last 7 days Radiated Energy Released TTNT graphs for Japan.
The cropped bars represent magnitudes over 3.7, therefore the more bars that reach the top the more TTNT was released. Graph shows up to 13/04/2015 18:00:34 UTC, the last 2 graphs are either reviewed and automatic mix, so will change in the next few days. 12th was the busy day with M3.9, 3.9, 4.3, 4.3, 4.3, 5.6 quakes

rightclickviewimageforfullsize (1400pixels wide)

I have just started this on japanearthquakes, graph thumbnail and (Bing) map popup when you click it, on Preview Style.
For comparison here is the graph the day of the M9 on 10/3/2011UTC

further to: muzzy
a little gif animation to show how the JMA/NIED review changes things
animation shows the preliminary versus reviewed, the preliminary one is the one with the lighter orange bar at 19:25.
the graphs show the bigger quakes in a lighter hue of orange, so bigger the quake the lighter the hue . And a couple of others were added or upgraded or downgraded in sizeThat 5.6 at 19:25 downgraded to 5.2 so being smaller the bar is darker, and the new one added on the graph in front of the 5.2 was a 3.7 Southwestern Ryukyu Isl

I have noticed that generally the review reduces the magnitude reading compared to the automatic reading, note also the 3.6 and 15:07 and 3.5 at 15:15 also went down, to 2.9 and 3.4 repectively.
for clarity here are the 2 images together, preliminary on the top, reviewed below

the first half of the preliminary graph had reviewed data to 18:00hrs, that is why no change there.
therefore caution should be taken when looking at preliminary (automatic) data

The Russians have finally got an interactive map showing earthquakes by GSRAS
