  • 10/05/2020 -- THOUSANDS OF HOT SPOTS appear across Plate + New Madrid -- Plate shifting? Big quake?

    Video at URL. Lots more hotspots occurred yesterday along the New Madrid fault zone, stretching down into Louisiana. I believe he first noticed hot spots occurring on the New Madrid on 10/4. Also hot spots occurring at the Washibngton Idaho border. Dutchsinse believes that hot spots appearing on the Short Infra Red spectrum is an indication of seismic stress could be an early indicator of earthquakes.

    The new research provides the first quantitative synthesis of faulting across the entire continent, as well as hundreds of measurements of compressive stress directions—the direction from which the greatest pressure occurs in the Earth's crust. The map was produced by compiling new and previously published measurements from boreholes as well as inferences about kinds or "styles" of faults based on earthquakes that have occurred in the past. The three possible styles of faulting include extensional, or normal faulting, in which the crust extends horizontally; strike-slip faulting, in which the Earth slides past itself, like in the San Andreas fault; and...
  • Tectonic Time Bomb: Recent Burst Of Seismic Activity Has Scientists Taking Notice

    SACRAMENTO (CBS13) — A recent burst of seismic activity along the West Coast has scientists taking notice. They believe these small tremors could potentially be a precursor to something larger. Over the last few weeks, these small tremors have been reported along the coast of northern California, up to Washington. Scientists said it’s due to the phenomenon called “slow-slip,” and it’s happening north of us out in the Pacific. “The Juan de Fuca plate, is what it’s called, is sliding under North America, and sometimes it’s locked, and sometimes it slips. But when it slips, it’s building up stress elsewhere...

    A vast mass of hot rock is welling up underneath Vermont and extending into other subterranean regions below New England, new research shows. Scientists used a network of thousands of seismic measurement devices in the largest geological study of its kind, detecting the enormous blob upwelling under Vermont, New Hampshire, and Massachusetts – and possibly elsewhere.

    a debate is emerging between the San Francisco Public Utilities Commission (PUC) and the Bay Area Water Supply and Conservation Agency over the potential disaster if the 89-year-old Mountain Tunnel, which supplies 2.6 million Bay Area homes and businesses with water, collapses. The PUC acknowledges that the tunnel does have a chance of "catastrophic collapse," which would require repairs costing $100 million or total replacement, costing up to $630 million. But the PUC’s 10-year-old 4.6 billion water system improvement program did not include the Mountain Tunnel in its plans. ... The risk right now is that the tunnel lining could...

    Mountain Tunnel, a key part of the Hetch Hetchy water system - which supplies 2.6 million Bay Area residences and businesses - is at risk of a "catastrophic collapse" and will cost more than $100 million to repair or up to $630 million to replace, according to the San Francisco Public Utilities Commission. City officials have known for 25 years that significant work is needed on the 19-mile-long tunnel just outside Yosemite National Park in a steep, hard-to-access wilderness area. They considered making it part of the PUC's decade-old, $4.6 billion water system improvement program, which is now more than...

    A research team from China's University of Science and Technology detected tremors in the sea near the Malaysia Vietnam border on March 8 hours after MH370 disappeared from the radar screen. In a report published on its website, the Wen Lianxing Research Team said it suspected the tremor to relate to the missing MAS plane because the area "is not within seismic zone." "The incident happened at 2.55am on March 8, about one-and-a-half hours after MH370 lost contact at 1.30am. "One of the two possible locations is (an area) about 116km to the northeast of MH370's last confirmed location," it...

    For decades, the giants of the oil industry were confounded by salt. While oil companies for years had shot sound waves into the deep to help create images of undersea geology, salt located far under the floor of the Gulf of Mexico was unpredictable. It muffled reflections, or bounced them away from survey vessels, leaving geophysicists in the dark. But that was before a series of recent seismic imaging breakthroughs involving supercomputers and the largest moving objects in the ocean. The advancements helped oil companies peek under salt layers located miles below the Gulf and have spurred a number of...

    Israel conducted a massive controlled explosion to calibrate instruments at seismic monitoring stations worldwide, officials said. Using 100 tons of explosives, The Geophysical Institute of Israel conducted the explosion at a site in the Negev on Wednesday. It registered 2.7 on the Richter scale, and created a mushroom cloud that reached the height of up to 1.78 miles, or three kilometers, Haaretz reported Thursday. Local scientists and scientists from the U.S. and France as well as journalists observed the blast. Dr. Rami Hofstetter, head of seismology at the Geophysical Institute told the newspaper the experiment was important to study how...

    BOSTON – In an epic upset in liberal Massachusetts, Republican Scott Brown rode a wave of voter anger to defeat Democrat Martha Coakley in a U.S. Senate election Tuesday that left President Barack Obama's health care overhaul in doubt and marred the end of his first year in office. The loss by the once-favored Coakley for the seat that the late Sen. Edward M. Kennedy held for nearly half a century signaled big political problems for the president's party this fall when House, Senate and gubernatorial candidates are on the ballot nationwide.

    Two U.S.-based scientists said Sunday they've located the site of North Korea's second nuclear test last year more precisely than ever before, pinpointing it just 2 kilometers off the place where the first test was conducted in 2006. Lianxing Wen, a geophysics professor at the State University of New York in Stony Brook, and his graduate student, Hui Long, located the epicenter of the second nuclear test on May 5 last year with a margin of error of only 140 meters, compared with 3.8 kilometers achieved by the U.S. Geological Survey. "We locate the 2009 test at 723 meters north...

    Redoubt volcano erupted for the second time this morning with a huge explosion at 9:24 that sent a cloud of ash to 65,000 feet above sea level. It looks like the plume is going to drift kind of over Prince William Sound and then into the Copper River, Cordova area, and then into the Panhandle," said Alaska Volcano Observatory geologist Chris Waythomas in Anchorage. "It could cause some real serious issues for aviation throughout the day, and I wouldn't be surprised if some flights are going to be canceled here," he said.

    Posted this question on another thread but had very little response. As I look at the ring of fire right now, there is a massive amount of activity, BIG activity in the Pacific ocean towards Asia. There is also a lot of activity in South America and a little in Central America. The only thing on my chart on the west coast that registered at 4.0 or above was a small quake in Oregon. Question is, with all of these plates shifting, and the plates around our nation's plates staying pretty quiet, what is this doing to our risks of...

    Source: University of Southern California Date: August 27, 2007 Los Angeles Enjoying 1,000 Year Seismic Lull Science Daily — The Los Angeles basin appears to be in a seismic "lull" characterized by relatively smaller and infrequent earthquakes, according to a study in the September issue of Geology. By contrast, the Mojave Desert is in a seismically active period. Seismic activity alternates between the two regions, the study suggests. The lull in the Los Angeles basin began 1,000 years ago, said the authors, led by James Dolan, associate professor of earth sciences at the University of Southern California. "The past 1,000...

The location is near the most active part of the New Madrid Seismic Zone, the source of at least three major earthquakes in the winter of 1811-12, before the region was heavily populated and developed. This location will allow instruments in the...
