Why The Earthquake Near San Francisco Is Just The Start Of The Shaking In California.
http://theeconomiccollapseblog.com/archives/why-the-earthquake-near-san-francisco-is-just-the-start-of-the-shaking-in-California

The average rate of big earthquakes — those larger than magnitude 7 — has been 10 per year since 1979, the study reports. That rate rose to 12.5 per year starting in 1992, and then jumped to 16.7 per year starting in 2010 — a 65 percent increase compared to the rate since 1979. This increase accelerated in the first three months of 2014 to more than double the average since 1979, the researchers report.

Oklahoma, which used to rarely ever have significant earthquakes, has experienced over 2,300 earthquakes so far in 2014.

That is absolutely staggering.

ZENICA Bosnia (Reuters) - Thousands of Bosnians paid their last respects on Monday to five miners killed after an earthquake triggered a collapse at the Raspotocje mine and trapped 34 miners 500 metres below the surface.

In the third serious mining accident this year, a 3.5-magnitude earthquake near the central town of Zenica on Thursday caused rocks in the mine to burst, spewing out rubble that sealed off the miners in an underground passage.

Emergency teams reached the body of the last victim on Sunday night, after digging for 80 hours through tight underground corridors filled with methane.

Miners in working outfits and helmets carried the green-draped coffins of their colleagues for an Islamic prayer led by Bosnia's chief mufti at Zenica's main square.

"Just a few days ago we were celebrating his new job, and now we are burying him," said Damir Bradarac, who attended the funeral of his cousin Hajrudin Bradarac, who was killed at the mine four days after he started work there.

A day of national mourning was declared in Bosnia's autonomous Bosniak-Croat Federation, where the mine is located.

The Raspotocje mine produces coal for Bosnia's largest power utility, EPBiH, and employs 430 miners. Experts say it is the most dangerous of all Bosnian mines because of frequent rock bursts caused by tremors at its deep underground pits.

Thirty-nine miners died in a rock burst at the mine in 1982.

"Our miners can no longer work at such depths," said Sinan Husic, the head of the Federation miners union, who said he would seek new funds to improve safety at the mine.

Normally, Dry Creek, just west of Napa, lives up to its name this time of year. But three days after the South Napa Earthquake, it suddenly sprang to life.

“This was completely dry and right now it’s running at the rate that we’d normally see in May or so,†said Garrett Buckland, overlooking a stretch of the creek about 2.5 miles above where it empties into the Napa River. Buckland is a vineyard consultant who pays close attention to the hydrology of the Napa Valley. In September, he said, Dry Creek doesn’t usually make it as far as the river

When he started hearing the sound of moving water shortly after the magnitude-6.0 temblor, Buckland said he wasn’t entirely surprised; he said the same thing happened after a 4.9 temblor near here in 2000. Based on that experience, Buckland was willing to make a prediction.

“This will continue to flow all the way until it dries up next year,†he ventured. “All those changes in cracks and adjustments to the fissures all across this area are really just releasing a ton of really, really cold, crisp, clean groundwater, basically.â€

JAKARTA: A 6.2-magnitude earthquake struck off the central Indonesian island of Sulawesi on Wednesday (Sep 10), according to the US Geological Survey (USGS), sending panicked residents running from their homes.

The USGS initially reported the quake's magnitude at 6.5 but later revised it down. The quake struck in the Molucca Sea between Sulawesi and the Maluku chain of islands, but Indonesian officials said there was no threat of a tsunami.

Earthquake Unleashes Avalanche Over Sprawling Glacier (Photo)

An earthquake that rattled remote parts of Alaska and northwestern Canada in July triggered an avalanche that spilled mounds of snow down a steep mountainside. NASA scientists flying over the region captured dramatic photos of the quake-induced landslide just days after the event.

A 6.0-magnitude earthquake shook sections of Alaska and Canada's Yukon Territory on July 17. The quake struck Seward Glacier, which is located 62 miles (100 kilometers) from the Alaskan city of Yakutat, reported the Alaska Earthquake Information Center.

NASA scientists based in Fairbanks, Alaska, flew near Seward Glacier one day before the quake, on July 16, and observed that an earlier landslide had strewn rocks and other debris across the icy slopes. Four days after the earthquake, on July 21, the scientists revisited the site and discovered that a quake-induced avalanche had blanketed the mountainside in snow, covering much of the previous landslide's rocky trail. [On Ice: Stunning Images of Canadian Arctic]

"It's obvious that many big debris and snow slides happened in this short time window," NASA glaciologist Kelly Brunt said in a statement. "This is a super steep area, so you get a lot of activity here. The bulk of the activity in this case is probably associated with the July 17 quake."

Brunt and her colleagues snapped photos of the earthquake's aftermath using a digital camera mounted inside the nose cone of NASA's high-altitude ER-2 aircraft. The researchers flew within 1.2 miles (2 km) of the earthquake's epicenter.

The scientists were already scheduled to conduct flights over Alaska, near Seward Glacier, to test an instrument called the Multiple Altimeter Beam Experimental Lidar (MABEL), which is designed to detect changes in Earth's landscape — particularly Arctic sea ice — using lasers and photon detectors.

MABEL sends out pulses of laser light and measures how long it takes photons to bounce off Earth's surface and return to the detectors. The pattern of photons can help scientists determine elevation changes and characteristics of the landscape, including areas where ice is thinning, or the location ofmelt pools during Arctic summers.

MABEL is being used to help scientists develop ways to interpret data for the upcoming ICESat-2 mission, scheduled to launch in 2017. The ICESat-2 mission will collect data on elevation changes of ice sheets in the Arctic, which could help researchers determine how sea-ice thickness is fluctuating over time.

    Swedish earthquake shakes parts of Finland An unusually strong earthquake in central Sweden on Monday was also felt in Finland.

 

The University of Helsinki’s Institute of Seismology says that an earthquake occurred shortly after 4 pm in central Sweden, with a magnitude of 5.2 on the open-ended Richter scale. It says the temblor took place some 10 kilometres under the earth’s surface

The institute adds there were a number of observations of the quake in the Pirkanmaa and Satakunta regions of south-western and central Finland. There was also an observation in Vantaa that was likely related to the Swedish quake.

It couldn't happen here?

According to Matti Tarvainen of the Institute of Seismology, the quake was strong enough to have caused minor damage.

He says that a quake of this size has apparently never taken place in Finland, and according to current models would be impossible here.

Neighbouring Sweden is more susceptible to seismological activity due to the Scandinavian mountain range. There are also several fault lines in southern Sweden, Tarvainen told Yle on Monday.

Swedish institute rates it at 4.1

Swedish public broadcaster SVT says the quake was felt in the Dalarna and Gävleborg areas on Monday afternoon. The Swedish national seismological network, based at Uppsala University, says a quake with a magnitude of 4.1 occurred at 3:08pm local in the southern Härjedalen, some 42 km south of Sveg and 73 km north of Mora.

Residents commenting on social media reported houses shaking for several seconds, but no serious damage or injuries.

Earthquake in Philippines on Saturday, 20 September, 2014 at 13:28 (01:28 PM) UTC.

 

Several earthquakes that struck parts of North Cotabato on Saturday, September 20 - the highest recorded at magnitude 5 - damaged 82 houses and a church, and caused minor injuries on a boy, local authorities said. Cynthia Ortega, Provincial Risk Reduction and Management Council action officer of North Cotabato, said that Barangay Luayon in Makilala town was the most badly hit, with 82 houses damaged by the tremor, 15 of which were destroyed. A church was also reportedly damaged by the earthquake. Ortega also said a boy suffered "minor bruises" from falling debris and hollow blocks from his own home, apparently one of those badly damaged by the tremor. Several hours before a magnitude 5 earthquake struck 14 kilometers southwest of Kidapawan City in the province, a magnitude 4.6 earthquake of tremor was recorded 6 km southeast of Makilala town at 5:59 am. Several more earthquakes were recorded in the province throughout the afternoon but only a few recorded felt intensities. Barangay Luayon in Makilala town was celebrating its 62nd founding anniversary on Saturday when the quake happened. Governor Emmylou Mendoza, who was in Barangay Luayon as a guest speaker at the village's anniversary ceremony, personally witnessed the tremor. "I was there when the jolting happened. People had to stop for a while during the program when the tremors were felt, and then continued as soon as the movements stopped. But despite the earthquake the activities [continued]," Mendoza said. The Philippine Institute of Volcanology and Seismology (Phivolcs) said that at 12:26 pm Saturday, a magnitude 5.0 earthquake struck 14 km southwest of Kidapawan City. Intensity 4 was felt in Kidapawan City and Makilala, while Intensity 3 was felt in M'lang and Tulunan towns. Intensity 2 was felt in Matalam and Antipas towns. Phivolcs said aftershocks were expected in some areas in North Cotabato. As of posting, Philvolcs recorded a total of 14 tremors in North Cotabato, the last at 3:43 pm, all but one in Kidapawan. Of this number, only 4 reported felt intensities.

Seismotectonics of South America (Nazca Plate Region)

The South American arc extends over 7,000 km, from the Chilean margin triple junction offshore of southern Chile to its intersection with the Panama fracture zone, offshore of the southern coast of Panama in Central America. It marks the plate boundary between the subducting Nazca plate and the South America plate, where the oceanic crust and lithosphere of the Nazca plate begin their descent into the mantle beneath South America. The convergence associated with this subduction process is responsible for the uplift of the Andes Mountains, and for the active volcanic chain present along much of this deformation front. Relative to a fixed South America plate, the Nazca plate moves slightly north of eastwards at a rate varying from approximately 80 mm/yr in the south to approximately 65 mm/yr in the north. Although the rate of subduction varies little along the entire arc, there are complex changes in the geologic processes along the subduction zone that dramatically influence volcanic activity, crustal deformation, earthquake generation and occurrence all along the western edge of South America.

The Australia-Pacific plate boundary is over 4000 km long on the northern margin, from the Sunda (Java) trench in the west to the Solomon Islands in the east. The eastern section is over 2300 km long, extending west from northeast of the Australian continent and the Coral Sea until it intersects the east coast of Papua New Guinea. The boundary is dominated by the general northward subduction of the Australia plate.

Along the South Solomon trench, the Australia plate converges with the Pacific plate at a rate of approximately 95 mm/yr towards the east-northeast. Seismicity along the trench is dominantly related to subduction tectonics and large earthquakes are common: there have been 13 M7.5+ earthquakes recorded since 1900. On April 1, 2007, a mate.1 interplate megathrust earthquake occurred at the western end of the trench, generating a tsunami and killing at least 40 people. This was the third mate.1 megathrust event associated with this subduction zone in the past century; the other two occurred in 1939 and 1977.

Tectonic Summary Seismotectonics of Alaska

The Aleutian arc extends approximately 3,000 km from the Gulf of Alaska in the east to the Kamchatka Peninsula in the west. It marks the region where the Pacific plate subducts into the mantle beneath the North America plate. This subduction is responsible for the generation of the Aleutian Islands and the deep offshore Aleutian Trench.

The curvature of the arc results in a westward transition of relative plate motion from trench-normal (i.e., compressional) in the east to trench-parallel (i.e., translational) in the west, accompanied by westward variations in seismic activity, volcanism, and overriding plate composition. The Aleutian arc is generally divided into three regions: the western, central, and eastern Aleutians. Relative to a fixed North America plate, the Pacific plate is moving northwest at a rate that increases from roughly 60 mm/yr at the arc's eastern edge to 76 mm/yr near its western terminus. The eastern Aleutian arc extends from the Alaskan Peninsula in the east to the Fox Islands in the west. Motion along this section of the arc is characterized by arc-perpendicular convergence and Pacific plate subduction beneath thick continental lithosphere. This region exhibits intense volcanic activity and has a history of megathrust earthquakes.

The central Aleutian arc extends from the Andreanof Islands in the east to the Rat Islands in the west. Here, motion is characterized by westward-increasing oblique convergence and Pacific plate subduction beneath thin oceanic lithosphere. Along this portion of the arc, the Wadati-Benioff zone is well defined to depths of approximately 200 km. Despite the obliquity of convergence, active volcanism and megathrust earthquakes are also present along this margin.

Mexico City, September 28 (RIA Novosti), Dmitry Znamensky - At least eight people have died and six injured as a result of an earthquake in Peru, the country's authorities reported Sunday.

"We have examined the area and confirm the deaths of eight people – one man and seven women that also include four teenagers," Police Chief Rodrigo Prado was quoted by RPP radio as saying.

Tremors with a magnitude of 5.1 were registered in the province of Paruro, which is located in the region of Cusco south of the country.

All the victims used to live in the village of Miska, which is situated in the area that has suffered the earthquake the most.

There is no land connection with the village since the roads are buried beneath landslides.

Peru's Prime Minister Ana Jara Velásquez said on her Twitter account that a rescue team were dispatched to provide help to those affected by the earthquake. According to her, up to 90 percent of the buildings in Miska have been destroyed. The electricity, she said, is off as well.

Seismotectonics of the Himalaya and Vicinity

Seismicity in the Himalaya dominantly results from the continental collision of the India and Eurasia plates, which are converging at a relative rate of 40-50 mm/yr. Northward underthrusting of India beneath Eurasia generates numerous earthquakes and consequently makes this area one of the most seismically hazardous regions on Earth. The surface expression of the plate boundary is marked by the foothills of the north-south trending Sulaiman Range in the west, the Indo-Burmese Arc in the east and the east-west trending Himalaya Front in the north of India.

The India-Eurasia plate boundary is a diffuse boundary, which in the region near the north of India, lies within the limits of the Indus-Tsangpo (also called the Yarlung-Zangbo) Suture to the north and the Main Frontal Thrust to the south. The Indus-Tsangpo Suture Zone is located roughly 200 km north of the Himalaya Front and is defined by an exposed ophiolite chain along its southern margin. The narrow (<200km) Himalaya Front includes numerous east-west trending, parallel structures. This region has the highest rates of seismicity and largest earthquakes in the Himalaya region, caused mainly by movement on thrust faults. Examples of significant earthquakes, in this densely populated region, caused by reverse slip movement include the 1934 mate.1 Bihar, the 1905 M7.5 Kangra and the 2005 M7.6 Kashmir earthquakes. The latter two resulted in the highest death tolls for Himalaya earthquakes seen to date, together killing over 100,000 people and leaving millions homeless. The largest instrumentally recorded Himalaya earthquake occurred on 15th August 1950 in Assam, eastern India. This mate.6 right-lateral, strike-slip, earthquake was widely felt over a broad area of central Asia, causing extensive damage to villages in the epicentral region.

HONG KONG: A strong 6.0-magnitude earthquake hit southwest China's mountainous Yunnan province late Tuesday (Oct 7), the US Geological Survey (USGS) said. 

The quake struck at the shallow depth of 10 kilometres at 9.49pm local (Singapore) time in a region that lies close to China's borders with Myanmar and Laos.

China's official Xinhua news agency said at least one person had been killed and 19 others injured. "Many houses collapsed and we are investigating the casualties," a local official told the agency. "The aftershocks seem non-stopping."

The epicentre was located in Jinggu County, 85-kilometres from Pu'er city, in a region famous for its tea plantations. The quake was also felt in Yunnan's provincial capital Kunming.

USGS had earlier given a lower magnitude reading of 5.8 and a shallower depth of five kilometres. Xinhua gave a significantly higher reading of 6.6-magnitude, citing the China Earthquake Networks Centre.

The agency said buildings shook for several seconds, according to local officials, while some phone calls to the region went unanswered.

"The whole building was shaking terribly with a loud cracking sound. Plates fell off in the kitchen. We all ran out and the streets now are packed with people," Li Anqin, a woman living in Weiyuan town, the county seat of Jinggu, told Xinhua via telephone.

Photos on social media showed damaged houses, cracked walls and fallen roof tiles, and crowds of people gathered outside into the night.
