Every day or once a week, our original stories and digest of the web's top headlines deliver the full story, for free. Kathryn Miles descends into mines in the Northwest, dissects Mississippi levee engineering studies, uncovers the horrific risks of an earthquake in the Northeast, and interviews the seismologists, structual engineers, and emergency managers ... Fracking involves blasting water, sand and chemicals deep into the ground to fracture rock to obtain oil and natural gas. The consultants' report, commissioned by the U.K. government and published on Tuesday recommends that fracking should be halted temporarily if there is a tremor greater than magnitude 0.5 on the Richter scale. After years of skepticism, in April, the Oklahoma Geological Survey said that the state’s staggering rise in earthquakes “is very likely” triggered by waste-related injecting wells. The recent investigation by Colorado and U.S. Geological Survey scientists is the first to take a comprehensive look at this issue. January 20, 2015 Sean Adl-Tabatabai Sci/Environment 0. This SEAOC Blue Book: Seismic Design Recommendations is the premier publication of the SEAOC Seismology Committee. The name Blue Book is renowned worldwide among engineers, researchers, and building officials. Out of the more than 106,000 wells reviewed, roughly 27,000 fell into the “associated” category. At enhanced oil recovery wells, material is injected deep into the earth (adding pressure) and then later pumped back up (decreasing pressure) nearby. These quakes are barely felt, let alone damaging. Scientists at the University of Colorado Boulder and the United States Geological Survey analyzed data from earthquakes and more than 106,000 active injection wells across the central and eastern part of the nation, the largest such study to date. In the US, interviews with Environmental Protection Agency (EPA) scientists and leaked documents have shown that, since the 1980s, EPA investigations into the oil and gas industry's environmental impact—including the ongoing one into Found inside – Page 159Extracting oil and gas from shale rock involves cracking, or fracturing, a layer of underground rock ... studies. So do injection wells cause earthquakes? Then there’s “produced water,” the naturally occurring water that flows up a well during production. Researchers did not study whether the technique of fracking itself (the process used to stimulate a well before extraction) causes earthquakes. However, the boom in fracking has led to much more wastewater being produced and injected underground, and its rise coincides with the increase in earthquakes. Opposition to fracking has ramped up since the release of the 2010 documentary "Gasland," which shows residents of small town Colorado setting alight tap water they charge was soured by nearby oil industry activity. The answer is a clear yes, because, simply put, fracking is the very definition of an earthquake. In 2011, a magnitude-5.6 quake struck Prague, Okla.; the damage was mainly limited to cracks in some buildings, collapsed roofs and items falling off walls. Energy companies are increasingly using the technique across Canada, where there is already regular seismic activity and an ever looming threat of various sized tremors. Primarily, during the fracking process: “ [Earthquakes] were caused by fluid injection during hydraulic fracturing in proximity to pre-existing faults. Among all the factors reviewed, researchers found one statistically significant relationship between earthquakes and the amount of waste injected each month. The purpose of this book is to get a practical understanding of the most common processing techniques in earthquake seismology. The book deals with manual methods and computer assisted methods. Wastewater is produced through both conventional drilling, as well as after a well is fracked. Fractured Communities reveals how this contested terrain is expanding, pushing the issue of fracking into the mainstream of the American political arena. But there have been a few noteworthy exceptions that scientists believe are likely tied to injection. Includes: site-response analyses, behavior of seawalls, lifeline performance, damage to 4-story apartment buildings and much more. Over 100 photos, charts and diagrams. Found insideTexas regulators, however, have yet to confirm any examples of fracking ... rock and tight oil sand formations, which causes thousands of micro-earthquakes. In Oklahoma, U.S. officials have severely curtailed operations after injection of waste water underground caused several earthquakes above magnitude five – one nearly 180,000 times … Wells further away from the fault line were not related to the tremors, according to the study. The aim of this book is an applied and unified introduction into parametric, non- and semiparametric regression that closes the gap between theory and application.

A study published in the November edition of Seismological Research Letters concluded that fracking operations triggered a series of earthquakes up to … Found insideThis book provides an integrated approach to the assessment of seismic hazards. The reduction of losses expected by future earthquakes is probably the most important contribution of seismology to society. One of the paper’s surprising findings has nothing to do with the wastewater disposal wells mentioned above. The study tracked magnitude-3.0 (M3) and greater earthquakes on the moment magnitude … Dr. Kayal has put together his vast experience in this useful book. This timely compilation addresses several aspects of microearthquake studies as well as their application to comprehending complex seismotectonics of South Asia. The principal concerns are their possible human health and environmental impacts, particularly "man-made earthquakes." "Fracking causes earthquakes, studies confirm" 04/17/12: 5: Confirmed: Fracking caused Ohio earthquakes: 01/03/12: 6: Does Fracking Cause Earthquakes? Mark Zoback, a Stanford University geophysics professor who co-authored the Oklahoma study, said his findings are “completely in sync with” the state Geological Survey’s announcement. South Africa and Australia will jointly host the Square Kilometre Array, which promises to be the world's largest telescope, the international consortium in charge of the project said Friday. They’ve closed at least 50 wells and reduced the allowable volumes of injection liquid at more than 150 others. Opposition to fracking has ramped up since the release of the 2010 documentary "Gasland," which shows residents of small town Colorado setting alight tap water they charge was soured by nearby oil industry activity. Audience Relations, CBC P.O. "Hydraulic fracturing has been inferred to trigger the majority of injection-induced earthquakes … Both studies confirm that processes linked to the extraction of oil and gas through hydraulic fracturing, or fracking, can trigger manmade earthquakes. You will be redirected to ICN's donation partner. Closed Captioning and Described Video is available for many CBC shows offered on CBC Gem. Fracking has been confirmed as the cause of an earthquake that rattled homes from Sylvan Lake to Red Deer last March, say government scientists. Found inside – Page viiPreface This book contains papers concerning earthquake preparation and the ... findings of the studies set out in this collection confirm to some extent ... U.K. experts, meanwhile, point to a study released Monday that found recent earthquakes in northwest England were caused by fluid injection into a nearby fault zone as evidence fracking can be safe when conducted by responsible operators. Before 2009, Oklahoma was struck by fewer than five earthquakes of magnitude 3.0 or higher a year. AGA, Bloomberg NEF. Earthquakes induced by fracking are different than natural quakes, according to the USGS, in “source, frequency, propagation, and ground shaking characteristics.” (Source, here, denotes not … The U.S. Geological Survey has maintained that fracking is … Both studies confirm that processes linked to the extraction of oil and gas through hydraulic fracturing, or fracking, can trigger manmade earthquakes. In Texas, regulators are currently investigating whether the activity of two companies has contributed to earthquakes near their operations. Clarification: Details were added to this story to clarify the role that unconventional fracking has played in the increase in seismic activityy in oil- and gas-producing regions. Found insideTo address this need, Negative Emissions Technologies and Reliable Sequestration: A Research Agenda assesses the benefits, risks, and "sustainable scale potential" for NETs and sequestration. According to the USGS study, the earthquakes are linked to the disposal of wastewater produced during fracking, not the fracking process itself, as previously reported. This book examines historical evidence from the last 2000 years to analyse earthquakes in the eastern Mediterranean and Middle East. Their research was published Thursday in the journal Science.

From the impact of war or technology on disease emergence to the development of enhanced disease surveillance and vaccine strategies, Microbial Threats to Health contains valuable information for researchers, students, health care providers ... However, due to seismic monitoring advances and the increasing popularity of hydraulic fracturing to recover hydrocarbons, the number of earthquakes – felt and unfelt – associated with hydraulic fracturing has increased in the past decade. Fracking may be to blame for recent earthquakes in … In western Canada and the central United States, an emerging side effect of the fracking boom is the proliferation of suspected man-made earthquakes. The study found that although it is rare for fracking associated with shale gas extraction to cause earthquakes large enough to be felt on the surface by … Weingarten and his colleagues also discovered that wells blasting the most wastewater into the ground, and at a faster rate—more than 300,000 barrels a month—were more likely to be linked to earthquakes. The consultants' report, commissioned by the U.K. government and published on Tuesday recommends that fracking should be halted temporarily if there is a tremor greater than magnitude 0.5 on the Richter scale. In 2014, that number jumped to more than 140 earthquakes in the same range of intensity. –Fracking causes earthquakes, studies confirm earthquake A sudden and violent shaking of the ground, sometimes causing great destruction. Previous studies have suggested that fault slip in shale formations targeted by fracking occurs too slowly to produce an earthquake. following tremors of magnitudes 2.3 and 1.5, CBC's Journalistic Standards and Practices. With this information at hand, Weingarten and his colleagues ran statistical analyzes searching for patterns between the associated and non-associated well groups in order to answer the simple, critical question: Do wells associated with earthquakes have distinct attributes? Routine seismic monitoring in mines was introduced over 30 years ago with two main objectives in mind: • immediate location of larger seIsmIC events to guide rescue operations; • prediction of large rockmass instabilities.
