I guess since the EMSC one has not been reviewed we will see a reduction.

Showed up good on LISS SNZO graph

IC that Geofon also have it at 6.2, manually Revised

Magnitude: 6.2
Epicenter: 102.54°E 5.19°S

Status: manually revised
geofon.gfz-potsdam.de...
On their list they have a C, never noticed that before, it means "If an automatic solution was checked and found to be OK without manual revision, it is marked as confirmed a C "

Could be possible USGS got it wrong

BMKG (Indonesia) have

Date 18/01/2011-02:20:54 WIB (UTC +7)
Magnitude 6.5 SR (ML)
Depth 10 Km
Location 5.29 LS 102.47 BT
Information:
The quake's epicenter was at sea 115 km Southwest Bengkulu
Felt at (MMI):
III Kepahiang, II-III Liwa, III - IV Manna, III - IV Bintuhan, III - IV Bengkulu,

BMG has changed their web site around a bit , new address
www.bmkg.go.id...

edit: just had a look at what usgs based their result on;
mb = 6.1 (136) ML = 6.0 ( 16) mblg = 5.1 ( 9) md = 0.0 ( 0) MS = 5.9 (343)

usually a mb reading comes out way higher in Mw , 2011, same old same old, manipulating the numbers

Yep there were a few more in the afternoon NZDT, spreading out from the morning locations, seems to have died off now though,

Something new I thought I would do is a 7days interactive map of NZ quakes.
Not quite USGS or EMSC with the speed of reporting them, but at least once a day. (I haven't got the $60million budgets)
All I have to do is add the kmz file each new day and drop the first day

I find it good for spotting Swarms that I might otherwise miss when just looking at a couple of days.

On this one there are 3 main swarms going on and of course the Darfield, Canterbury aftershocks keep on going

Hm. don't like it when they are near Taupo. But there are other volcanos near by aren't there? It's been fairly active over there lately? (Sorry, been caught up in Qld flood stuff and have no idea what's going on in the rest of the world).

Hello quakewatchers, I'm wondering if you could post a good link for webicorders that are showing the swarm in Guy Arkansas. Thank you.

Well, that swarm at Waimangu WAS a warning sign.
I didn't feel it, there was a big storm going on here at that time, heavy rain and strong winds, wouldn't have noticed this quake unless it was within 5km of US.
Was located right under Ngongotaha rhyolite dome.

No it has been pretty quiet (this is always a bad sign). 2011 started off with a Mag 4 every day some days 2 of them, and a couple of 5's spread throughout the country, last 2-3 days was very quiet.
Lake Rotorua IS a volcano crater.
The whole area between Ruapehu and the Bay of Plenty is a volcanic zone, known as the Taupo Volcanic Zone duh:

And only 10km deep. It's a bigun'.
Hopefully that's as bad as this one gets. Unless of course it's a secret HAARP thing. Or an atomic blast. Or maybe it's just a quake.

NM,seems to be a false one

Does water cause large earthquakes? Pakistan was hit with major floods recently.

Puterman wake up and find me in my corner of the universe. I have a real job for you.

It's been downgraded to 7.2 and 52 miles deep. Quite big changes...and it has said it was already reviewed before. hmmmmm

Is that the Antolian Plate? I always get these wrong. There is also earthquakes in Yemen today. I know nothing of this but has one plate knocked the other?

Guys, what is your take on this?

I can't find ANY fore-shocks to this quake (7.2 in Pakistan), and so far after 1.5 hours, no AFTER shocks.

Do you think there might be something bigger in the works???? I sure hope not.

Live Pakistani News Feed - SAMAA.TV

Does anyone speak Pakistani? I am curious to see if they are mentioning the fact that there have been no aftershocks.
