Decent sized quake for alaska. Sure showed up well on the Yellowstone seismos!

No tsunami:

I felt it too here in the North Island.
Just filled out areport to USGS and Geonet.

I had just got up and sat down at the computer with my coffee, and felt "dizzy" I thought maybe it was me, there was no shaking just the whole world was wobbling slightly, especially my chair.

Looking at the location in the Port Hills near Christchurch there is bound to be major damage

Wow - USGS now has it as a 7.2. I sure do hope the damage is minimal. Be aware of aftershocks!

From: NOAA/NWS/West Coast and Alaska Tsunami Warning Center
Subject: Tsunami Information Statement #1 issued 09/3/2010 at 9:46AM PDT

A strong earthquake has occurred, but a tsunami IS NOT expected along the California, Oregon, Washington, British Columbia, or Alaska coast. NO tsunami warning, watch or advisory is in effect for these areas.

Based on the earthquake magnitude, location and historic tsunami records, a damaging tsunami IS NOT expected along the California, Oregon, Washington, British Columbia, and Alaska coasts. At coastal locations which have experienced strong ground shaking, local tsunamis are possible due to underwater landslides.

the Geonet site is slow, lots of postings of felt reports
They have it at 7.4ML

MM8 at Waikuku Beach

Where is Moorfnz?, she MUSThave felt it, maybe the power is out?

www.radionz.co.nz...
A strong earthquake of 7.4 magnitude has hit 30 kilometres west of Christchurch.
The quake occurred at 4.35am at a depth of 33 kilometres.
It was also felt in other parts of the South Island and in Wellington, where it was felt in a rolling motion which lasted for about 40 seconds.
Radio New Zealand listeners report particularly strong effects in Christchurch, with one resident saying the turned his house upside down, with crockery breaking.
Another said the power had gone out.

USGS has the location too far east.
This is the Geonet map




[edit on 3-9-2010 by muzzy]

Yep, I'm in Christchurch...it woke me up and I've never felt one that strong before...apparently it was just south of the city!
Need a new dinner set, but the fish tanks are intact!
We can expect aftershocks for a while.

Unfortunately it wasn't "the big one" that is due as it didn't occur along the alpine fault.

I still shaking....adrenaline...and there are continuous aftershocks!

If you felt it please fill this out as it helps with information gathering and planning for future events!


Freaky!

Yeah, apparently the power is out across much of the city!

This is going to make a mess of the seismos

Rata Peaks

McQueens Valley

SNZO South Karori

Muzzy, look at the YS-Seismos: www.isthisthingon.org...

there is nothing. Hmmmm!?

reply to post by muzzy


Yup, all the stations on the planet are still showing the S-waves right now (except for the shadow zone, of course).

This quake is the biggest I have ever captured live in GEE, BEFORE the USGS reported on it. I posted a screen shot of it here:

www.abovetopsecret.com...

When I first see something like this at a distance (in other words, from a distant station- in this case I was monitoring the Australia area), I can tell right away that it is a big quake just from the duration of the signature. Even though at that point I can't be sure of the magnitude, until I start opening stations closer and closer to the epicenter and watch the amplitudes go up.

Those few minutes before the USGS reports, when I see something big has happened, but don't know exactly where, are a time of excitement, challenge, and prayer that everyone's ok.

Now it's a 7.0. oO

And in few minutes it will be a 6.9 ...

Why? => Statistic : )

good to hear from you.
sounds like his is a huge event, "whole row of shops demolished", "bridges damaged" etc sounds worse then the 2008 Gisbourne Dec 6.8 quake.
The location is weird, no known faults there between Darfeild and Rolleston.
Bet the Lincoln Campus is a mess inside.

You have to smile about the tsunami reports, it was in the middle of the Canterbury Plains

Good catch

WOW! I just got up and look at all the big quakes!?!?? My friends in NZ, are you all ok? Anyone heard from MoorfNZ?

reply to post by muzzy




On a more serious note I am praying that Moorfnz is Okay and that she can get on here as quickly as she can to let us know. Do any of you know how far away from quake she is?

emsc seem to be on the ball with the fastest reporting of aftershocks 2 x 5's so far.

I'm not sure where she lives, somewhere in Canterbury I think

Come to Austria because it is always calm.

Hope Moorfnz is healthy.

Yep, we're all ok here, shaken and slightly stirred, but we have power etc whereas quite a lot don't (including all of rural canterbury!).
I never take tsunami reports lightly, after all, it was a very large quake and there was the possibility...don't let your guard down!

apparently thjere is looting going on in the CBD, but I can't find any more of that....damn those dropkicks and bogans....

Hope everyone else is unhurt and just on edge....

kia kaha, take care....


Oh hell...I work in the Geology Deparetment and Canterbury Uni...I can tell, already, that there will be a mess (four story building) and I bet a lot of our equipment is damaged...xrf...isotope lab, my lasersizer......

...at the end of the day they are only 'things' and as long as people aren't hurt....

I bet it goes down like you say.

Geofon had it at 6.7 right from the start
GeoAustralia 7.1
