USGS has updated their site since I last visited. Quite an improvement. The zoom and pan map makes it a lot easier to get perspective on the location. I get their email notices, but there are very many of those. I'm sure I went there after the Japanese Tsunami, though it have been through EQuake3D which gives a graphic representation of quakes by accessing USGS data.

The sort of thing we get excited about :-)

But the quake occurred about 13 km underground.

This is a good thing.

If xilman was speaking of the horizontal dstance to the surface point directly above the epicenter, from Pythagoras we have sqrt(10^2+13^2) = a bit more than 16 km as-the-slanted-drillbit-travels diagonal distance. However, the characteristics of earthquake wave propogation may render that particular measure irrelevant.

The only reason that the quake was felt in three counties (Derbys, Notts and Leics) is that those counties meet at a point close to the epicentre.

I've not heard from my family but I doubt they felt anything. The very fact I've not heard from them supports that supposition.

During a major earthquake, should you climb under furniture to try protect yourself, or immediately adjacent to same?

Today’s Earthquake Fact (via [url]http://earthquake.usgs.gov/earthquakes/[/url] )

Each year the southern California area has about 10,000 earthquakes. Most of them are so small that they are not felt. Only several hundred are greater than magnitude 3.0, and only about 15-20 are greater than magnitude 4.0. If there is a large earthquake, however, the aftershock sequence will produce many more earthquakes of all magnitudes for many months.

This latest one that I've just felt is a different spot but close and stronger.

Hi,

I live in Wellington (Southern city of the North Island, very close to epicentre), and I can report that it was scary as heck.

The earthquake is now reported to measure magnitude 6.5.

I've heard that there is minor structural damage to some buildings, mostly broken windows (I know for a fact that a window upstairs is broken in my hostel), and a few buildings have cracks, as well as some damage to roads.

There are currently no reports of fatalities that I have heard, but I've heard sirens of fire engines and police constantly since the quake happened over two hours ago.

This morning there was an earthquake measuring 5.8 and on Friday morning one measuring 5.7, too. I'm very worried about there being more now.

Didn't expect this to reach international news though!

it seems to be downgraded to a 6.0 but still is in the significant category on the USGS.

I was in the car returning from work, didn't feel a breeze. When I reached home everybody was on the street in my mooban (neighborhood) including my family, and I didn't know why. They said they felt the shaking darn well...

My girls (SWMBO included) were scared and didn't want to go back into the house for a while, they played and talked with other children/people outside. I parked the car, went straight into the house, took a shower and a nap... :w00t: This morning there was a small aftershock (like a big truck passing on the the street, no shaking), which again I didn't feel, I was still sleeping, SWMBO said she was in the kitchen making breakfast, and she felt the glasses vibrating a bit.

6.8 in Mexico.

[QUOTE]May 13 (Reuters) - An earthquake of 6.8 magnitude struck off the coast of Panama early on Tuesday, the U.S. Geological Survey reported.

The quake hit the sea, 132 km south of the city of David at 0635 GMT at a depth of 10km, the USGS added.[/QUOTE]

Apparently the great 1906 SF quake was historically unusual in being a one-off:

[url=www.mercurynews.com/science/ci_25793975/quake-cluster-likely-strike-bay-area-scientist-say]Earthquake cluster likely to strike Bay Area, scientists say[/url]
[quote]The Bay Area's Big One will still be plenty big, but it might not be just one, according to a study released Monday by U.S. Geological Survey scientists.

A flurry of mid-sized quakes is more likely to strike the Bay Area rather than a giant 1906-esque rupture, said David Schwartz, a paleoseismologist at the USGS's Menlo Park office and the lead author of the study, which appeared in June's Bulletin of the Seismological Society of America. The study marks the first comprehensive history of the Bay Area's seismicity dating to 1600.

A quake cluster isn't necessarily good news, as it could keep communities constantly cleaning up the earthquake damage, several experts said.

"It presents a very different problem in how you respond and recover from earthquakes," Schwartz said.

After the 7.8-magnitude 1906 earthquake, the 20th century was abnormally stable, he said. Therefore, an earthquake cluster is overdue, the scientists said.

"Basically, what goes in, must go out," Schwartz said. The region's seismicity stems from the clash of two massive plates in the earth's crust. The Pacific Plate is sliding northwest, while the North American Plate is moving southeast.

Since 1906, the plates have moved about 13 feet in the Bay Area. Like a compressed spring, they're ready to burst.

In the Bay Area, the plate boundary fractures into a handful of fissures, all generally trending northwest-to-southeast. The well-known San Andreas Fault, which Schwartz calls the "master fault," is accompanied by the San Gregorio Fault, the Hayward Fault, the Calaveras Fault and the Rodgers Creek Fault in the North Bay, among others.

Future quakes are expected to spread out along these faults."These faults are being stressed by the plate movements... and they all have to catch up," Schwartz said.

The various faults "talk" to each other, said Roland Burgmann, an earth scientist at UC Berkeley. "The communicating family of faults sometimes tend to rupture together as a group or shut each other off."

The 1906 earthquake was likely a fluke, the perfect alignment of conditions that allowed 300 miles of the San Andreas Fault -- from northern Mendocino County to San Juan Bautista -- to release its pent-up pressure. This massive shaking kept the area unusually calm for a century, Schwartz said.

"Eventually, there should be more clusters," Burgmann said.

The scientists based their prediction on the historical record, which shows a cluster of quakes shook the Bay Area from 1690 to 1776. At least six earthquakes, ranging from 6.3 to 7.7 magnitude, rattled the region's major faults during that period, Schwartz said.

The cumulative release of energy from the quakes roughly equals that of the 1906 earthquake, Schwartz said.

"This is a summary of a tremendous amount of work," said Greg Beroza, a Stanford seismologist who was not involved with the study.

Previously, other scientists had scoured the records kept by the Franciscan missionaries at San Francisco's Mission Dolores starting in 1776, Schwartz said. He called the Spanish missionaries "the first seismographers." They described the rumblings in their records, allowing scientists to assess the earthquake's strength by extrapolating from the amount of damage the Franciscans described.

Scientists dated the earlier quakes by digging trenches and calculating the age of charcoal or other organic materials found several feet below the surface, Schwartz said.This technique misses small or deep earthquakes, which don't break the surface.[/quote]
Much as appreciate the work geologists do, I simply can't associate with them - they're such a fault-finding bunch.

using these as though on the moment magnitude scale I get an average energy of roughly a 7.3 quake.

Apparently where we live (NE Arkansas) is a high-risk earthquake area.

:max:

You live in an area with deep-injection waste disposal wells.

EDIT: Hold on to your hats if this induced shaking causes New Madrid to cut loose.

Bárðarbunga: rumble, rumble, rumble.... (volcano watch!)

[QUOTE]Well, after receiving almost no news coverage, Bárðarbunga - Iceland's biggest volcano and the "big sister" of Laki (the deadliest volcano in recorded history) - is finally starting to get noticed by the news.[/QUOTE]

Be sure to check out all the links to graphics and animations. There are some fantastic visualizations.

Brian and I visited both Vesuvius and Etna a few weeks ago.
At Vesuvius, it is easier to reach the top and there are great views over the Bay of Naples, but there has been no serious eruption for over 50 years, so all the stones and ash are old and the volcano feels dead.

On Etna, the landscape is much blacker, ash strays on to the access roads, and as you get higher you start hearing the volcano rumble a few times per minute.

Iceland has now issued a red alert to aviation:

The BBC, I believe, has always prided itself on getting spellings and pronounciations of foreign names right.

I always find their correspondents quite impressive with their apparently correct local pronounciations .... until I hear them doing it with Dutch language words!
