Quake Watch 2010

No, you don't have to learn how to understand it. Just be able to find the station you are looking for in the list.

Null brain power required which is a good thing or I could not manage it

I don't know how to find stations in the list. Seismology is a whole new field for me. (actually so is geo). I got to sleep now, busy few days coming up. But will have a closer look at it (& geo ref) in the next week.
I noticed the sun and the planet have quietened down so more time to catch up on all this reading!

My sincere apologies. When you look at a USGS listing of an earthquake it looks like this:

Couple of quakes near me.
Didn't feel either, although plenty others did.

Thank you for the effort in this post. For total beginners this really helps a lot.

A quake in Nebraska today. Not so very notable except for the location.

Idaho Fault Line Could Spur 7.5-Magnitude Quake
Scientists Map Previously Unknown Fault beneath the Rockies and Say an Eruption Could Come Soon; Area is Sparsely Populated

www.cbsnews.com...

A newly-discovered seismic fault line in central Idaho could produce a 7.5-magnitude earthquake, according to scientists at Idaho State University.

The 40-mile-long fault line beneath the northern Rockies had not been mapped before and could unleash a quake "in the next few decades," according to one of the scientists, who spoke to Reuters. "If it does happen it will be a rather large earthquake," Glenn Thackray, chairman of the school's geosciences department, told Reuters.

interesting eh?

Here's another headline breaking today

Earthquake risk high in Panama, data suggests

www.cbc.ca...

Two faults that run through central Panama have ruptured both independently and in unison over the past 1,400 years, suggesting that Panama City and the Panama Canal face "a significant seismic risk," new research suggests.

And then the earth shook 4.2 quake: It wasn’t related to the windstorm, was felt around much of the state, centered in St. Helens zone
JOHN DODGE; Staff writer | • Published November 17, 2010

www.theolympian.com...

The Lewis County earthquake that jolted southwest Washington on Tuesday morning apparently was centered at the north end of the Mount St. Helens seismic zone, according to state Department of Natural Resources geologist Tim Walsh.

There were no immediate reports of damage from the 7:51 a.m. quake, which had a magnitude of 4.2 and was centered about 6.2 miles west of Morton. It appears to be the largest quake in the Mount St. Helens zone in 10 to 15 years, Walsh said.

In South Sound, residents who awakened from a windy night riddled with power outages reported feeling two jolts that some mistook for explosions.

Just had a decent quake here on the Kapiti Coast, NZ quite a sharp jolt, house shook like crazy, rumbled a bit first.
Nothing on Geonet yet, felt like a mid Mag 4 or a big 3 if close by.
I reckon in the Tararua Mts to the east.

368 Felt reports at the moment, our suburb of Raumati Beach 20km away has the most so far

I was right about the location , it had that "rocky" feel about it, different feel to the ones that come from off shore to the west.

I see RSOE has it on their map (using Geonet as source)
hisz.rsoe.hu...


I notice RSOE always has ALL New Zealand earthquake locations listed as "Woodville County"

There is no such place, we don't have Counties here, we have Provinces.
Woodville is a town east of Palmerston North in the Manawatu, but it certainly is not a County.

Even the Christchurch aftershocks are shown as "Woodville County"

Underneath Haiti, Another Big Quake Waiting to Happen

Last week, on the morning of Nov. 11, a tremor shook the Port-au-Prince suburb of Carrefour. It was a minor geological event, but given the still fresh and haunting memories of the 7.0-magnitude earthquake that hammered Haiti on Jan. 12 and killed some 230,000 people — many of them in Carrefour — even that mild shudder caused public panic. The only reported injuries, in fact, were due to people scrambling to take cover.

I know Glenn. He was a visiting Academic. Cooked his meals for a week.

He knows his stuff.

As always, kindly sharing your knowledge. Thank you for showing me where to find that info. I love this stuff but don't have the time to learn it. You make it easy and quick - straight to the point and all laid out. You should be a teacher (if you aren't already).

That's pretty close to the big one last month. The 7.7 was 3.484°S, 100.114°E. ..about 100km

Well it IS RSOE isn't it. Nuff said!

Please, translate all the lines. I know you live upside down but I have great difficulty reading New Zealand English.

Thank you Zenius and Tzavros for those kind words. That makes the effort worthwhile.

I have always believed that help files should be 'how to do' something unlike Microsoft and so many others who think it should be 'what it does' - which of course is useless if you don't know 'how to do it'.

No I am not a teacher. Perhaps I should have been. I did teach computing for a year once as a temporary lecturer and quite enjoyed it.
