Who is right, or is this 2 events?

Edit: No scientific data for USGS yet. Looking at EMSC I am guessing they are possibly right.

More EMSC data just arrived. Looks closer to 6.1 than 5.5

Edit: USGS just in

mb = 5.7 ( 32) ML = 5.2 ( 12) mblg = 5.0 ( 6) md = 0.0 ( 0) MS = 0.0 ( 0)

Eh? Wot? How do USGS get a 6.1 from that?

EMSC just dropped it to a 5.8.

www.emsc-csem.org...

USGS sticking at 6.1 which now looks wrong.

Just what one needs when they wake up in the morning, another magnitude conundrum going on
Its interesting to watch the networks rearrange the magnitude when the event first happens eh.

I got these from EMSC, British Geological Survey had the highest reading, that NEWS (NORSAR) 4.5 probably twisted the final result downwards, in fact I think they should have ignored that contribution, the location was way out too.

quite a few 6.2's in the EMSC phase data too.

and Geofon split the difference and called it a 5.9

definitely a "strong" quake either way

edit: ha! I just checked back on EMSC and now its a 6.0

Want to try another one, this time both in mb. lets see what they finally come up with, surely this will end up a 6Mw too

Is anyone else getting a problem connecting to GEE or to Vase or is it just me?

It has been offline for 2 days now!

reply to post by PuterMan
maybe it was shut down due to the recent activity near Westcoast.
and didnt want the headaches of answering questions,.

reply to post by PuterMan


Nope. Not just you. I have been trying to get onto GEE since yesterday...keep getting an error.

Good thing I'm not paranoid or anything.

I have got Vase back again. They changed something in the configuration. I got an email from the Vase programmer. (I have emailed him before)

I am trying to find out what the problem is, or rather how to fix, GEE. It looks like it is the same problem as it says it cannot find a CORBA server and it was this parameter the asked me to change on Vase. Apparently we are not the only ones having problems with this.

reply to post by Anmarie96

Hi Anmarie, well that was a surprise when got the computer up and running this morning
Geonet have 5.9ML
www.geonet.org.nz...

I didn't feel it, slept in again, woke at 1:30am but went back to sleep.
Interesting that I seem to sleep soundly prior to when there is a big quake within 500km, could be some kind of calmness that sets in before all h_ll breaks loose

Our Internet was off for about 20 hrs, just spent an hour on the phone with Telecom troubleshooting it out, couldn't find the problem, they were going to send a technician around to the house but after I hung up I plugged the fax machine back into the wall socket and everything fired up and worked

Amazing how dependant we have become on the Internet, we had no idea what was going on in the world, apart from the Radio and the morning newspaper.

Never had this trouble when we used to write letters to each other and post them

reply to post by muzzy


Felt by my friends in Hawke's Bay

reply to post by PuterMan


I wrote to the folks in charge of GEE to ask when we might expect it to be up and running again - here is what I got which confirms there is a problem but does not address my question at all

Sorry, there are some issues with the systems at the IRIS DMC that prevent GEE from accessing the servers it needs to get data. Until they are able to resolve this issue, GEE will not work.

Sorry
Philip

That 5.93ML at Atiamuri looked like it was a strong sharp jolt.
Not an unusual location at all, they get a lot of 4's around there.
I took a couple of screenshots for posterity
nice and thick on Mangatainoka, which always seems to be one of the most sensitive siesmograhs in the country



and on LISS SNZO (marked with red arrow)

I was looking on LISS, and it looks like something happened across the globe at the same time 10:00 GMT. Japan & Alaska are particularly extreme. Does anyone know anything more about this? Live Internet Seismic Server

reply to post by onthelookout


Hi onthelookout. First it is nothing to be concerned about - for you anyway. The people where it happened might not agree.

Yes I do know what caused it, and so will you in a short while.

Take a look at this: Understanding Seismograms and LISS helicorders

You only get a few occasions to try this in a year so it is worth going through the exercise to see if you can work out for yourself what caused this. If you don't want to do this then I will give you a clue. The earthquakes was in a country considered to be on the 'axis of evil' by the US and is found opposite the Arab states. The name begins with 'I' and it's leaders name sounds like "I'm a dinner jacket"

If you are really stuck just come back and ask but this is an excellent learning opportunity for you.

Edit: I would use this one to determine the time. I can tell you now it is not 10 o'clock.

What the heck is this - they just listed it ----- Oh wait --- it's just below Gillette - where they are doing all that mining

This is what Philip said to me:

Hi

Unfortunately, there is no way to change the nameserver in GEE, so until the DMC fixes the problem with their systems, GEE will not work.

Sorry,
Philip

Chris from the Vase team said:

Great. We have some problem forwarding from dmc to dhiserv.

Somewhere in GEE there is a configuration the same as Vase. You need to change it as you did for Vase.

Please contact Philip Crotwell, who wrote GEE, to see how. He is at Univ of So Carolina.

Here is his email:

The problem is that there is no configuration file. This is was as a result of my fixing Vase about which he said....

The CORBA server is the problem. I think it is fair to say that this is not going to be a quick fix if they don't have any configuration in GEE. What a daft idea!
