One June 11, 2003 the first volcanism article,
Volcanoes In California, Idaho, and Pacific Northwest Building Towards Catastrophic Eruptions, reveals a startling discovery to science the 'earthquake boom' (see list item 11 of History of 'Breakthrough' Technology).
Currently a mystery to seismologists, a powerful explosion sound which eludes detection by the best of seismographs, is a real earth event and should be correctly classified as an 'earthquake'. The rare earthquake boom is part of a 'family' of five types of events the earth can generate of which only two are known by science. It is important for residents near volcanoes to be aware of the 'earthquake boom', although an unnerving experience doesn't indicate an actual explosion occurred or that an eruption is imminent. This article gives insight into why these events occur and what they mean. Included are some hair raising stories from Mt. St. Helens climbers who experienced a fantastic 'boom'.
Quake surprises Summerville, South Carolinaby Adam Parker - The Post and Courier - November 20, 2005Trucks rumbled by, but that wasn't it.
A C-17 or fighter jet might have passed over, but that didn't do it either.
There's been some roadwork in the area, which could easily be confused with tectonic activity, but that had nothing to do with it.
The
boom heard across much of Summerville, and the vibration that followed, was actually a little earthquake, the second this year in the area, according to Pete Jenkins, director of the Earthquake Center at Charleston Southern University.
The quake, which struck about 3 p.m. Saturday, raised eyebrows and worried children, but caused no damage. The U.S. Geological Survey took note of the event but did not report its magnitude as of late Saturday.
It came on the heels of the Earthquake Center's Earthquake Awareness Week, co-sponsored by the South Carolina Emergency Management Division. The event concluded Nov. 12. Classes were taught at Charleston Southern University, lectures were presented at the College of Charleston, and drills were arranged at all the public schools in the state, Jenkins said.
The program offered the perfect impetus to become aware of the region's shaky ground.
Buddy Farmer said he took notice after Saturday's quake.
"My wife thought I had fallen down upstairs," said Farmer, who has lived in Summerville for 37 years and is no stranger to seismic activity.
"It seems like there's a little shaking going on every couple of months or so," he said.
Actually, the last little bit of shaking happened on Feb. 22, when the Middleton Place-Summerville Seismic Zone experienced a 2.15 magnitude earthquake, according to Jenkins.
Twelve small quakes struck in 2004; 22 in 2003.
Jenkins said 10 to 20 a year is typical, and that this year is an anomaly. "Hopefully we're not going to make up for it from now to the end of the year," he said.
4.1 Quake Rattles Bellingham, Washington Area - November 23, 2005 - By KOMO Staff & News ServicesWhatcom County - A small earthquake shook the area around Deming in Whatcom County Wednesday. There were no initial reports of any injuries or property damage.
The Pacific Northwest Seismographic Network at the University of Washington said the magnitude 4.1 quake occurred at 12:53 p.m. and was centered about five miles east-northeast of Deming, which is west of Mount Baker. It was about a third of a mile below the surface, which is considered shallow.
In the first half hour after the quake, 25 people reported feeling it, describing the shaking as moderate. Some people who called the media reported hearing a loud
boom before the quake.
Bill Steele, a UW seismology spokesman, said the quake was the strongest one in Washington in more than a year. The last magnitude 4 quake was in August 2004 near Goat Rocks, between Mount Rainier and Mount Adams, both inactive volcanoes.
Tiny earthquake shakes St. Louis, Missouri region - By Eric Hand - Post-Dispatch 11/23//2005A minor earthquake ruptured Tuesday night just east of the Mississippi River near Washington Park.
Dozens of St. Louis area residents reported feeling weak shaking with no damage, according to the U.S. Geological Survey.
The magnitude 2.5 earthquake occurred at 11:05 p.m. Tuesday with an epicenter one mile west of Washington Park. The earthquake ruptured 8 miles below the earth's surface.
By noon today, 48 people from the St. Louis region had reported feeling the earthquake as weak, in two of the lowest of nine possible shaking categories, according to the U.S. Geological Survey earthquake hazards program. Did you feel it?
Small earthquakes abound in the New Madrid Seismic Zone. There have been 27 tiny earthquakes 2.0 or greater in the seismic zone since the beginning of 2005, according to an earthquake catalog kept by the University of Memphis Center for Earthquake Research and Information
This one, the 28th, was felt perhaps because it was so close. The earthquake was closer to St. Louis than any magnitude 2.0 or greater quake in at least 30 years, according to a search of the University of Memphis catalog, which includes quakes as far back as 1974.
Big bang shakes up Dryden, Ontario area - By Bryan Meadows - Nov 25, 2005, 23:05The earth moved for Dryden-area residents Wednesday evening. Glasses tinkled, a few homes shook and a large bang was heard about 8:30 p.m. during what seismologists are calling a small 1.5 magnitude earthquake, with an epicenter about three kilometres south of the city.
Anne Owens, who lives with her husband Trevor on Wabigoon Lake's Larson Bay, said Thursday that the couple heard a deafening bang, like a sonic
boom or explosion.
She said her husband told her it didn't sound anything like earthquakes he experienced while living in Los Angeles. It was a like a propane tank exploded, or a sonic boom from an aircraft flying beyond the speed of sound, Owens related.
Judi Lynch, also of Larson Bay, said she heard the big bang, but experienced no shaking.
Two of 10 people who called local radio station CKDR about the loud noise, said they felt their homes shake and items had fallen off shelves.
The Geological Survey of Canada's (GSC) website (http://gsc.nrcan.gc.ca/) said Wednesday's earthquake was the second seismic event this week in the area. A 1.6 magnitude quake hit 57 km south of Sioux Lookout at about 4 p.m. Tuesday.
Seismic analyst Veronica Peci said the Dryden-area quake was very local in nature.
She said the seismic event measured 1.5 on the Nuttli magnitude scale and occurred about six km from a GSC seismic monitoring station near Dryden.
In Canada, two magnitude scales, Richter and Nuttli, are used to determine the size of any seismic events: earthquakes, mining-induced events, induced earthquakes, and other blasts. Both scales are based on the maximum vertical S-phase amplitudes of the seismic waves recorded. The Richter scale is mainly used for Western Canada (west of the Rockies) and offshore seismic events.
GSC spokesman John Adams said Northern Ontario experiences about 40 small earthquakes a year.
Most are not felt because, he said, they're not all that big and occur in sparsely-populated areas.
He said Northern Ontario earthquakes are fairly shallow and affect a relatively small area.
It's a pretty stable area (of Canadian Shield rock) . . . a long way away from plate boundaries, Adams said, adding shallow seismic events are normally associated with blasting due to road construction, or mine and quarry work.
As for the cause of the Dryden-area earthquake, Adams said it's likely associated with the Mid-Atlantic ridge and West Coast plate squeezing the continent and the Canadian Shield. It means the brittle crust is cracking a little bit. Meanwhile, the GSC is interested in what people saw, heard or felt during Wednesday's tremor.
Input can be provided via the website, Adams said.
(Northeast Missouri) The mystery surrounding a loud, explosion-like noise that had much of Northeast Missouri talking Tuesday afternoon is now solved.
It was apparently a sonic
boom, an explosive sound caused by the shock wave preceding an aircraft traveling at or above the speed of sound.
Officials at Whiteman Air Force Base in Knobnoster, Missouri have the official word on the mysterious boom.
The Kansas City Central Control Command was testing an F-18 Superhornet military craft.
They were flying in a FAA approved test corridor.
The noise happened around 3 p.m. Tuesday and was heard by viewers in Queen City, Novinger, Brashear, Edina, Kirksville and places in between.
Eerie recording captures sound of tsunami
Underwater microphones pick up dull, deadly roar in Indian Ocean - By Robert Roy Britt Senior writerSound from last December's huge tsunami-causing earthquake was picked up by underwater microphones designed to listen for nuclear explosions.
Scientists this week released an audio file of the frighteningly long-lasting cracks and splits along the Sumatra-Andaman Fault in the Indian Ocean.
The spine-tingling hiss and rumble is an eerie reminder of the devastation and death that is still being tallied in the largest natural disaster in modern times.
At least 200,000 people are thought to have died as a result of the magnitude-9.3 earthquake, the tsunami, and the lack of food, drinkable water and medical supplies that followed.
The audio recording of the quake starts out silent. A low hiss begins and the intensity builds gradually to a rumbling crescendo. Then it tails off but, frighteningly, builds again in waves as Earth continues to tremble.
The audio file is sped up 10 times to make it easier to hear. As it was recorded, the sound was at the lower threshold of human hearing, but it could have been noted by someone paying attention.
"If you were diving even hundreds of miles away you could hear this," said study leader Maya Tolstoy of Columbia University's Lamont-Doherty Earth Observatory. "You would hear it as sort of a '
boom.'"
Comment: Signs of the Times is often entertained by the newsletters of "Shorcha Faal," which are prolific and well-put together. In fact, if a person wasn't careful to check the sources, they might be taken in by them.
And that's not to say that there aren't a lot of reliable stories included.
The problem is: they are generally "linked" together by a very shakey lynchpin which, when discovered, makes one very suspicious of everything else.
The above linked article is a case in point. It is the lynchpin for the recent SF newsletter about all the mysterious "booms" going on in the U.S. which are supposed to be indicators of the imminent fracturing of the North American Plate. And certainly, taken together with the dam that has just collapsed in Missouri, and the gas geysers in Oklahoma, things are looking a bit suspicious. (Not to mention the lack of activity on the Western Rim of the Ring of Fire vs. all the activity on the Western Rim.)
"Sorcha Faal" refers to the author of the above linked article as "the United States Terra Research Institute in their report titled Mystery of 'The Earthquake Boom'.
What's wrong with that? Sounds like a legitimate government agency with real science going on and the voice of a real expert, right?
Well, if you do a bit of a websearch, you will find this interesting tidbit:
Thousands Flee After India Passes Along Sham Warning
Misinformation and chaos filled disaster's breach last week as thousands fled coastal areas of India and Sri Lanka after the Indian government put out a public warning that another earthquake, and subsequent tsunami, was imminent. The basis for the alarm: Readings supposedly taken by a contraption housed in the back of a pickup truck in Oregon. The warning was originally posted to the Web site of Terra Research and Consulting Services. The business's owner, Larry Park, claims to be a computer expert and earthquake forecaster, based on a new type of electromagnetic radiation he's discovered. He has no formal training in geology, and his theories have not been peer-reviewed.
So why did the Indian government act? Indian Science and Technology Minister Kapil Sibal explained that the U.S. office of the Indian Space Research Organization saw the prediction posted on Park's Web site, contacted Park, and then passed along the dire warning to the government in New Dehli. In retrospect, Sibal called Park's conclusion "unscientific hogwash," but it was the S&T Ministry that passed the warning along to the Home Ministry, which issued the warning. Sibal said he wasn't consulted before that alarm was sounded.
Park has a different version of events. He says he alerted filmmaker Mike McNulty, who passed the warning along to the U.S. embassies of India, Indonesia and Australia. On Dec. 30, McNulty, nominated for an Oscar for his 1998 documentary film "Waco: The Rules of Engagement" about the FBI siege of the Branch Davidians compound, told the AP "the forecast is January 1- it isn't game over yet."
The deadline passed, of course - so "game over" for Park's prediction. "There are lots of these charlatans out there, and the more publicity they get the more money they make," Steve Malone of the Pacific Northwest Seismograph Network at the University of Washington told the Seattle Post-Intelligencer. "There is no way to predict earthquakes ahead of time yet that's proven."
So everything is NOT as Sorcha Faal presents it. And we have caught him/her at it dozens of times. Why, if a person is trying to propagate truth, do they have to fudge their sources? There's no reason to make Larry Park appear to be a gov. scientist. But apparently, Sorcha realizes that most people will NOT click the links, or if they do, they will not then try to verify who is who and what their agenda might be.
And we aren't even saying that there is any nefarious agenda to Mr. Park. But there sure does seem to be a nefarious agenda behind Sorcha Faal.
Nevertheless, we are still left with those interesting "mystery booms" and collapsing dams, gushing gas geysers, and a whole host of fun things going on here on the Big Blue Marble that Sorcha rightly points out as being significant. Click the expandy thinger to read some of them, and let's leave it open for now. For all we know, Larry Park is right. But we strongly urge caution when reading Sorcha Faal - he/she "prestidigitates" information rather often, and we wonder why?
