The avatar size is 160 wide per the rools

Copy that to your PC and then upload as normal and set as your avatar.

ETA: I notice that the shadow shows badly on the avatar size so i have cropped that off. (Gives you a very slightly larger avatar)




Just got rid of the small whiter corners. Should look better in place.

Its hard to tell at this stage, a lot of those are Pegusus Bay aftershocks, but there seems to be more quakes being located elsewhere in NZ on a daily basis than there has been in the past. Most of those are small 2's, which I follow closely looking for hotspots.
Bay of Plenty quite busy, but it always is.

Anyway I don't know if is real but they say(government)that in February they may expect a big one.

4th small earthquake recorded near SC coast

hosted.ap.org/dynamic/stories/U/US_SC_EARTHQUAKES?SITE=AP

SUMMERVILLE, S.C. (AP) -- A fourth small earthquake in the past month has been recorded on the South Carolina coast.

The U.S. Geological Survey says a quake of magnitude 2.6 was recorded around 3 a.m. Wednesday about three miles south of Summerville.

The epicenter was about three miles below the surface. Quakes of such magnitude are not usually felt by people.

The quake was is the same area as a fault that caused the devastating 1886 Charleston earthquake that killed more than 100 people. That quake had a magnitude of 7.3.

Previous earthquakes occurred on Dec. 7, Dec. 21 and on New Year's Day.

I have had my eye on that area all year

They have had some big ones there in the last 10,000 years.

I hope it is not a little foreshadowing!

Wow, and I thought I was old. Can you really remember that far back or is this something that might benefit from a little linky-poo?

After quakes, owner to lower pressure in Ohio well

hosted.ap.org/dynamic/stories/U/US_GAS_DRILLING_EARTHQUAKES?SITE=AP

COLUMBUS, Ohio (AP) -- The owner of a northeast Ohio well used to dispose of wastewater from oil and gas drilling plans to remove material from it to help lower its inner pressure following 11 minor earthquakes.

State officials say they believe injecting wastewater near a fault line created enough pressure to cause seismic activity. The latest and largest quake was Saturday in the Youngtown area and registered at magnitude 4.0, which can cause moderate damage.

The Ohio Department of Natural Resources said Wednesday that Northstar Disposal Services LLC is taking 12 holding tanks to the site of the now-shuttered injection well to pump the material into the tanks.

Department spokesman Jason Fallon says he's unsure when the removal will start but seven tanks are already on the site.

The company hasn't returned phone and email messages left after business hours Wednesday.

How dare I overlook such a matter......not much info, but I left that page with a little more knowledge about the area then I did yesterday

Just happened in the DR. Now that's a bit big for the DR, and me thinks it could be a delay triggered fault from the 7 in Haiti a while back. Maybe it activated another fault and caused this quake. Maybe it didn't. But the Caribbean in general has my attention lately. After Japan, there is no telling what could happen down there with so many miles of subduction going on.

Last couple of years mag 4.5+

Historically this seems a fairly normal event for the area

In amongst that lot are these:

PDE 1979 03 23 193231.10 17.99 -69.04 80 6.4 UKPAS .C. ....... 45
PDE 1979 11 05 015112.90 17.83 -68.62 104 6.2 UKPAS 3F. ....... 64
PDE 1984 06 24 111711.92 17.98 -69.34 23 6.7 MsGS 5FM ....... 65

So it would seem that the area is capable of nearly Mag 7

Hey Puterman,

I have a question for you guys here. I noticed on the Live Earthquakes map a ton of "little quakes" from North to Southern California. Is this the norm?

About 20,000 people left homeless and severe damage in northern Dominican Republic from Samana to Santiago and Puerto Plata. Some damage occurred at Santo Domingo (Ciudad Trujillo) and slumping and sand blows were observed in the Yaque del Norte and Yuna River Valleys. The death toll was light because the quake struck in early afternoon on a holiday, when most people were outdoors. It was felt strongly (V-VI) in parts of Haiti and Puerto Rico, including San Juan; and (III) in the Virgin Islands and eastern Cuba. Almost all the people killed were drowned by a tsunami at Matanzas, near Nagua (Julia Molina). Although the waves were only about 2.5 m (8 ft) high at this location, they moved inland several km, causing such severe damage that the town was abandoned. Maximum wave heights were estimated at 4-5 m (13-16 ft) at Nagua. A small tsunami was recorded by tide gauges at San Juan, Puerto Rico; Bermuda; Daytona Beach, Florida and Atlantic City, New Jersey.

Yes that is normal, you will find California, Greece, New Zealand, parts of Chile and Scandanavia amongst others have lots of micro and minor size quakes every day.
'little' isn't a geoquakespeak word
Greece
New Zealand (felt quakes only listed)
Chile
Scandanavia

That Global Incident site is not very reliable when it comes to earthquakes, have a look at Putermans page with all the links to many earthquake pages country by country
QVS Loads of Links
Be prepared to be amazed at how many earthquakes there actually are every day (many hundreds globally)

reply to post by dreamfox1


see thats why that site is useless,
those 2 "light" aftershocks are probably the same quake at 22:02:40
how can they get the data before usgs, when usgs feed is the source.
thats the trouble with automated services.
there are only 2 quakes listed that are not from USGS feed, how can that be subjective?
where are;

a feed from ONE Govt agency does not a Global Incident Map make

Possibly more important is this one

Magnitude: 5.2

Region: Pacific-Antarctic Ridge
Depth: 15.9 km

on a spreading ridge and been going on for weeks now, certainly has the potential to cause a buildup at the subduction zones (if you believe in that theory) either side of the South Pacific,
