Quake Watch 2011

reply to post by Anmarie96

What the heck is this - they just listed it

Um, an earthquake perhaps?

Yup, just had another look at it. I can confirm that it is an earthquake. I guess it took them a while to work that out!

You edited your post. Maybe they thought it was a mine blast and eventually decided it was not.

Curious I am. Your weeny little bump from the 5.93 is dwarfed by the Iranian quake yet Iran only have that as a 6.2 Mb

2011/01/27 08:38:28.5 12:08:28 28.15 59.09 15 Mb:6.2 Kerman Province, 139 km North-East of Kahnuj

It seems a whole lot of shaking for a shallow low 6.

Look at it (your one) on URZ - good for about 8 days

USGS and EMSC both have it at 5.3?????????????

I don't have the Geonet version yet. They seem to come through in a bunch about midnight UTC or thereabouts.

ohhhhhh...ok I went through the link you sent and see now. It was the 6.0 in Southeastern Iran at 8:38:28 UTC. That was kind of fun.

I feel a little sheepish, but now I understand the graphs a LOT better. So thanks for that.

reply to post by onthelookout


No need to feel sheepish and yes spot on. It was a great opportunity to learn and the next time you will be able to tell others what is going on.

Glad it worked for you!

Hi Puterman. I have a question, the time displayed on the LISS helicorders graphs is it GMT or local ? I'm also trying out to pin point quakes (found today's bigger one) but sometimes my b brain gets tangled up in the calculations of time differences and the time it takes the waves to hit certain points on the globe...
Maybe I'm just tired cause it's around 2 am here

reply to post by Odyssian


The LISS main screen us usually dated as MST but all the enlarged versions of the station are in UTC.

Now I am not sure about that if you are using the US version of LISS but if you are UTC +2 that would make you Europe East time i guess so MST would be about 9 hours behind you.

The right LISS one to use

The wrong LISS one to use (USA local)

The time down the side is still UTC on both however.

Heard the 5.9 is at Taupo. Hope everyone is alright!

reply to post by PuterMan


Yeah big difference in duration between Iran and NZ, it must be something to do with depth, the NZ one was 150km.
I've noticed the NZ quakes don't show up much on LISS SNZO, sometimes a local 5.0 is little more than a heave in the line, must be something to do with he settings of the seismo.

I was just doing 25th UTC data and there was a 4.06ML right under Taumarunui Aerodrome, Waikato, not one single felt report , but the depth was 202km.

reply to post by crazydaisy


I haven't heard anything at all about this quake on the news.
If you look at the Shaking Map you can see most of the energy went South and South East.
It was in the Whakamaru/Maroa caldera group which is the part of the Taupo Volcanic Zone, its a really lively area for deep quakes, its older than Taupo itself, last eruption estimated 14,000 years ago.

That RSOE cracks me up, everything that happens in New Zealand is in the "Woodville County", there is no such place , there is a Woodville town in the Manawatu Province, but there are no counties, we don't have counties.
Someone should tell them.
Even the Darfield (Christchurch) quakes are in "Woodville County" according to RSOE.

This 4.0 aftershock just rocked my world.. I almost got on the floor to take shelter it was very shaky... v. close to my house and shallow...

I live in Saigon on the 3rd floor of a 3 story house in the middle of the city. I guess it was Wednesday the 26th about 2pm and I felt a big sway and I heard the metal stairway outside rattle for a few seconds. I thought wow an earthquake, looked outside and everything seemed normal. I forgot about the whole thing until last night I was having dinner with a few Vietnamese professors from a university and one of them brought it up. He said he had read about it in the paper but didn't feel it, he was worried because southern Vietnam isn't known for quakes and would not be prepared if a one hit. So today I looked at the Vietnam news and sure enough a 4.7 quake about 185km away from Saigon in the South China sea. Some reports had it lasting 1-3 minutes a few miles from where I live. My numbers may be off, I don't know all the technical details. Just thought I would share...

Thats interesting, thanks for the heads up.
The Vietnamese geological web site is not much help reporting these events.

I have spoken to several Vietnamese people here in NZ who said "heck yeah we get earthquakes alright"

last reported quake was the 5.2 on 31st Dec 2010 at Son La up North

They certainly do.

Take a look at these PDFs

ntur.lib.ntu.edu.tw...

eqtap.edm.bosai.go.jp...

www.seis.nagoya-u.ac.jp...

Yes, most of the quakes are up north, usually not much action in the south.. All the typhoons, floods and such always hit the northern or central areas. Living in Saigon is so boring!

Here's the article:

Interesting they have a map of the epicentre from USGS, but its not listed on the USGS Latest earthquakes page earthquake.usgs.gov...
despite being 4.8mb, over the 4.5 threshold of that page.

I seen 2 of those pdf's last night, wouldn't open for me then, but did just now

Hanoi right on a fault line eh

I think the North Island of NZ has got volcanic gastro problems

7 hrs prior to the 5.93ML at Pohaturoa volcanic dome Waikato, there were a couple of Burps at the Crater Lake Mt. Ruapehu strato volcano
3455916, -39.277, 175.56334, 2011/1/27 7:44:29, 0, 1.869, N of Crater Lake, Mt Ruapehu, Volcanic Plateau

and 3hrs after the 5.93 a fart from Lake Rotorua caldera
3456123, -38.08304, 176.25294, 2011/1/27 18:3:19, 128, 3.495, Lake Rotorua, Bay of Plenty

I hope she ain't gonna throw up next

BTW thats the 2nd Mag 5+ thats been right under a old volcanic cone in the North Island this month
the other was the moderate/strong/deep
3449463, -38.11591, 176.18695, 2011/1/18 8:45:47, 153, 5.744, Ngongotaha Dome, Rotorua, Waikato


edit: I'll put tis here because it has to do with Maroa anyway.
When I seen the dome beside the earthquake it didn't have a name on Google Earth so I went through the Smithsonian List for Moroa, and ended up creating a KMZ file of all (most) of the domes in the area.
A lot of the locations on Smithsonian were a bit off, so I fixed that by making my GE go max 3D so I could see the domes properly.
I also created 3 new Google Earth icons while I was at it, as I couldn't find any decent ones
heres the KMZ file for Maroa

Thanks for that Muzzy. So this is all part of Lake Taupo and "The Big One"?

What are these domes? To me domes means areas of uplift.

reply to post by PuterMan


I was just reading up on it.
www.teara.govt.nz...
www.teara.govt.nz...
Domes are created when the main eruption is over and lava oozes slowly out of a single vent, rather than a massive gas explosion that blows ash half way to China.
The ash and scoria builds up around the vent etc.
Mt. Ngauruhoe is a classic dome, although it looks like a volcano in its own right, it is just actaully a vent of Mt. Tongariro.
The North Island is littered with them from Ngauruhoe northwards.
I remember as a kid driving between Auckland and Wellington on many occasion my brothers and I would try to ID each cone as it came on the horizon all the way from the Desert Rd to Hamilton. (the old Shell road maps were better back then)
Auckland city is also littered with domes, many of them overbuild with houses.

I believe Little Krakatoa is also a Dome, coming out of the sea like it is, and its just a vent of the big old boy that blew in the 1800's

can this EQ be related to the hot-spot under jan mayen?
