RE,
This swarm looks like it may have legs. The last time I saw my inbox go nuts with USGS automatic earthquake emails was just befor Fukushima. The boxing day 2004 big quake and tsunami mostly generated aftershocks but not many preshocks to the big one. I just read on another site that the count on the swarm is 60 plus. I haven't gotten that many emails because of my magnitude filter setting (I've gotten around 15). Still, that's a lot. :o :jawdrop:

Whole Lotta Shakin' Going On- 7.4 El Salvador
« Reply #31 on: August 27, 2012, 02:46:53 AM »
Shakin' good now!  7.4....equivalent to around 2.7 MEGAtons.  By comparison, the "Fat Boy" dropped on Nagasaki (bigger than Hiroshima by almost double) was around 20 KILOtons.  Get it?  That quake just dropped down approximately 100 Nagasakis.  ONE QUAKE! How many went down in SoCal today? Where do YOU think all that energy went?  Mother Earth can drop down some Rip Roaring energy dissipation when she has a mind to do it.  We are FLEAS

Quake of 7.4 magnitude hits off El Salvador coast: USGS
 August 27, 2012 • 01:05 AM • last update 01:26 AM


A major earthquake of 7.4 magnitude hit in the Pacific Ocean about 78 miles off the coast of El Salvador late Sunday night, the U.S. Geological Survey said.

No destructive Pacific-wide tsunami is expected, and there is no tsunami threat to Hawaii, the Pacific Tsunami Warning Center said.

The center said, however, that although it did not know if a tsunami had been generated, a warning was in effect for Costa Rica, Nicaragua, El Salvador, Honduras, Guatemala, Panama and Mexico.

The earthquake struck 74 miles south of Usulutan, El Salvador, at a depth of 33 miles, the Geological Survey said.

There were no immediate reports of damage to coastal areas or to shipping.

This is the biggest quake so far but just look them on Google Earth. There are several fairly good sized quakes.

7.6 Magnitude Quake Hits Costa Rica

Costa Rica Earthquake 2012: 7.6 Magnitude Quake Hits Costa Rica

http://www.huffingtonpost.com/2012/09/05/costa-rica-earthquake-2012_n_1857743.html



NOSARA, Costa Rica — A powerful, magnitude-7.6 earthquake shook Costa Rica and a wide swath of Central America on Wednesday. There were no immediate accounts of injuries, but communications were down near the epicenter.

The USGS said the 8:42 a.m. quake struck about 38 miles (60 kilometers) from the town of Liberia. It was centered about 25 miles (41 kilometers) below the surface. The magnitude initially was estimated at 7.9.

In the town of Hojancha near the epicenter, city official Kenia Campos said the quake knocked down some houses and landslides blocked two roads.

"So far, we don't have victims," she said. "People were really scared ... We have had moderate quakes but an earthquake (this strong) hadn't happened in more than 50 years."

There were no initial reports of damage or deaths in the capital of San Jose, said Douglas Salgado, a geographer with Costa Rica's National Commission of Risk Prevention and Emergency Attention.

Salgado said, however, officials were having problem accessing the earthquake zone or reaching people there and were flying over the area to assess damage to highways and other structures.

The earthquake didn't knock out phones or electricity in the capital 88 miles (141 kilometers) from the epicenter, Salgado said by telephone, but communications were down near the epicenter.

"There's chaos in San Jose because it was a strong earthquake of long duration," Salgado said. "It was pretty strong and caused collective chaos."

At the Hotel Punta Islita in the Guanacaste area, "everybody is crying a lot and the telephone lines are saturated," said worker Diana Salas, speaking by telephone, but she said was no damage there

In the coastal town of Nosara in northwest Costa Rica, trees shook violently and light posts swayed. Teachers chased primary school students outside.

A tsunami warning was in effect for Costa Rica, Panama and Nicaragua, the Pacific Tsunami Warning Center said in a bulletin. It said it was unknown if a tsunami was generated, but the warning was based on the size of the earthquake.

Geohazard expert: Prepare for Arkansas quake, pipelines at risk


    * New Madrid Fault
    * September 3, 2012
    * By: Deborah Dupre


A geohazard supervisor with the Arkansas Geological Survey has advised Monday that people and pipelines in northeast Arkansas are at risk of the real possibility of an earthquake and to be prepared.

"On average, the region is having an earthquake every other day, so residents need to be ready," said Scott Ausbrooks, geohazard supervisor with the Arkansas Geological Survey about northeast Arkansas.

Ausbrooks is urging residents to prepare for an Arkansas earthquake, saying the risk of a major earthquake occurring in northeast of the state is a "real possibility."

"Unreinforced masonry buildings, brick buildings with no ductile frames (are at greatest risk)," Ausbrooks said. "When it shakes, there is nothing to hold it together."

"In a given 50-year period, the USGS (United States Geological Survey) says there is a 7 to 10 percent chance (of a magnitude 7 or greater earthquake)," he said.

"When you look at a 6 to a 6.7 on the high end, still a decent size and damaging earthquake, there is a 25 percent chance in the next 50 years."

The last earthquake of that magnitude along the New Madrid Fault was in Charleston, Mo., in 1895. With an earthquake of that size, the region would run the risk of major disruptions in services, Ausbrooks said.

"There is a risk to telecommunications and water," he said.

"And lots of pipelines crisscross the area, going to the northeast. Those (pipelines) are at risk."

There has been a direct correlation between the amount of fracking in Arkansas and the increased seismic activity. Environmental Modification (ENMOD) is impacting Arkansas residents and their human rights to security.

'Get a kit, make a plan and stay informed'

Sheila M. Annable, preparedness division director for planning at the Arkansas Department of Emergency Management, said, "We don't know of anyone in the country ready for a catastrophic event like this."

"If we get a truly large quake, it will have a significant impact on roadways, waters and gaining access into the most devastated areas will be difficult," she said.

"We encourage everyone to get a kit, make a plan and stay informed," Annable said, urging people to visit ready.arkansas.gov.

On that site, Arkansas residents are urged to assemble a kit including bottles of water, enough non-perishable food to last a family for three days, a battery-powered or hand-crank radio with extra batteries, a flash light with extra batteries, a first aid kit and a map, among other items.

The Center for Earthquakes and Information says survival supplies in an Earthquake Survival Kit should include:

Water-2 quarts to 1 gallon per person, per day.
First Aid Kit-ample, and freshly stocked.
First Aid Manual-know how to use it.
Food-canned or individually packaged;precooked, requiring minimum heat and water. Consider infants, pets, and other special dietary requirements.
Critical medication, extra eyeglasses
Can opener
Blankets
Radio-portable battery operated, spare batteries
Critical medication and eyeglasses, contact cases and supplies
Fire Extinguisher-dry chemical, type ABC
Flashlight-spare batteries and bulbs
Watch or clock-battery or spring wound.
COOKING:
Barbeque-use outdoors ONLY-charcoal and lighter, or Sterno stove
Plastic bags-various sizes, sealable
Pots-at least two
Paper plates, plastic utensils, and paper towels SANITATION
Large plastic trash bags-for trash, waste, water protection
Ground cloth
Large trash cans
Hand soap, liquid detergent, shampoo
Toothpaste, toothbrushes, dental floss
Deodorant
Feminine supplies
Infant supplies
Toilet paper
Powdered chlorinated lime-to add to sewage to disinfect and keep away insects.
Newspapers-to wrap waste, garbage; may also be used for warmth.

SAFETY

Heavy shoes for every family member
Heavy gloves for every person cleaning debris
Candles
Matches-dipped in wax and kept in waterproof container
Knife-sharp, or razor blades
Garden hose-for siphoning and fire fighting
Clothes-complete change kept dry

TOOLS

Axe

Shovel
Broom
Crescent wrench-for turning off gas main
Screwdrivers
Pliers
Hammer
Rope or bailing wire
Plastic tape
Pen and paper
Mini Survival Kit for Automobile

Non-perishable food-store in coffee cans
Boiled water
First aid kit and manual
Fire extinguisher
Blanket
Sealable plastic bags
Flashlight-spare fresh batteries and bulb
Critical medication, extra eyeglasses
Tools-screwdriver, pliers, wire, knife
Short rubber hose
Pre-moistened towelettes
Feminine supplies
Sturdy shoes and gloves
Your emergency supplies should be adequate for at least 72 hours (3 days).
A 10-day supply of water, food, and medicine is recommended.

Prepare yourself and your family now

Have an earthquake survival kit on hand.
All family members should know how to turn off gas, water, and electricity.
Plan family emergency procedures, and make plans for reuniting your family.
Know emergency telephone numbers (doctor, hospital, police, 911, etc)
Anchor heavy objects to walls (bookcases, wall units, mirrors, cabinets, etc.)
Never place heavy objects over beds, and keep heavy objects lower than head height of shortest member of family.

Annable also recommends insurance for northern Arkansas residents.

Surly1,
Excellent advice. It's amazing all the stuff we take for granted until it's not available.  :(

A large earthquake aftermath is very bad news.

Not so small if you live in Boston.     ;D   :laugh:

Two small earthquakes were recorded off the coast of New England Saturday night and early Sunday, specialists at Boston College’s Weston Observatory say. The first, which measured about 2.5 in magnitude, happened at about 10:31 p.m. Saturday about 41 miles east of Rockport, according to the observatory’s seismic detection recordhttp://feeds.boston.com/click.phdo?i=47059ee350c9035215de7841316ff11b      :icon_study:

I thought a snowleopard had a great deal of white in its fur, Snowleopard, sort of like that might give it a little camoflage in the snow,you know what I mean,survival of the fittest and all that. But maybe there was a nice brown spotted snowleopard in your momma's woodpile. Just goin by your picture and thinkin, that's all. Afterall mongrels do have the highest immunity and stronger if they've been treated right.

Lots of color variation in snowleopards, always some white underside and black spots, the rest ranges from grey/white to tan/brown or yellow/brown with varied intergrades.  Higher elevation ranges do tend to have whiter cats.  The eyes vary quite abit too.  Some pictures at this link: 

http://www.bing.com/images/search?q=Snow+Leopard&go=&qs=n&form=QBIR

Their camo can be quite good, snow or not, but it doesn't confuse IR scopes.  They are endangered and seldom seen in most of their range.  Not known to cross breed with other cat types!   ::)  Very good ambush hunters but never heard of one attacking a human.  Reportedly a minority eat substantial vegetation.  A different breed of cat!

Wonder if GO felt the Rattle in Bean Town?

Seabrook Nuke declared it an "unusual event".  Very unusual, just ask the locals around Fuk-U-shima.

4.6 earthquake in southern Maine rattles New England
 
Published October 16, 2012
 
Associated Press

PORTLAND, Maine –  An earthquake that hit southern Maine has rattled nearby New England states as far as Connecticut, including the Boston area.
 
The U.S. Geological Survey at first estimated the Tuesday evening quake as a 4.6 magnitude, but later downgraded that to 4.0. It hit at about 7:12 p.m. The epicenter, about 3 miles west of Hollis Center, Maine, is about 3 miles deep. That's about 20 miles west of Portland.
 
The Maine Emergency Management Agency had no immediate reports of damage or injuries.
 
In Waterboro near the epicenter, about 20 customers and staff at Waterboro House of Pizza ran outside when they heard a loud bang and the building shook.
 
The Seabrook Station nuclear plant, about 60 miles away in New Hampshire, declared an unusual event, but said it wasn't affected. The plant has been offline for refueling.

I'm on Cape Cod. The house shook slightly and all the windows rattled for about half a minute. Pretty cool actually- no damage of course. We don't get tremors like this all that often so we kinda have to go around and tell everyone all about it when we do.  :)

Re: Whole Lotta Shakin' Going On- Iceland quake swarms

"Interesting" quake swarms developing in Iceland:

An Earthquake swarm started in northern Iceland during the night to the 21th.

Hundreds of earthquakes have been recorded yesterday, last night and this morning outside Siglufjörður. The largest was the second time in the night, 5.2 in size. Human habitations quaking in Akureyri, dogs rushed up óhljóðum and items moved from one place. People were troubled, according to reporters in the north.
 No reports have been received of injuries, however, people or property. Several other earthquakes have been recorded over four dozens of tremors over three large. Bergthora Thorbjarnardottir, geophysicist at the Meteorological Institute, says a shaky offense that is not preceded volcanic activity. The epicenter is about twenty miles north of the town accounted for, at 6-9 kilometers.
 Earthquake had begun the previous night 20 km north SIGLUFJORDUR. Activity has come in waves but calm was between 15 and 23 o’clock yesterday. Furthermore, the cycle may come back with great force. She says that the area has calmed down tonight but it is not possible to predict whether earthquakes recurrence. The last quake of three large measured shortly before seven in the morning. He was of size 3.5 according óyfirfarinni automatic measurement. You can monitor the earthquake on site certified.
 Bergthora says shaking Tjörnes Seismic Zone could reach up to seven large. It can not be excluded a large tremor, but there is no evidence, however, especially for a large earthquake is coming.
 Earthquakes were well over the north and west, to form a Blönduósi in Fnjóskadal, Sauðárkrókur in Staircase,-exhibition, in Isafjordur, in dollars, in Húnaþing and Reykjadalur.
 Earthquakes are common in this area but has not previously been so dramatic cycles in this place.

@RE

Yeah, Iceland has lots of EQ swarms.   

The ones under the volcanoes are probably as ordinary as those we experience under Ranier, St Helens, Yellowstone and Mammoth.  Most folks are unaware of those swarms too.  I'm not sure anyone is keeping good track, but IMO this sort of activity is picking up worldwide.  You could be correct that it is insignificant.  I'm not entirely sure of that though.

 OTOH: The Tjörnes fracture zone has not experienced a swarm of this intensity or with a higher Mag EQ since 1976 per the Icelandic Met Office.  This is interesting to me, but apparently noone else here.  Won't bore you with further posts in this genre.
