Petersen, Charles S. Mueller, Morgan P. Moschetti, Susan M. Potentially induced earthquakes in Oklahoma, USA: Links between wastewater injection and the 2011 Mw 5.7 earthquake sequence. + Author Affiliations Significant earthquakes are increasingly occurring within the continental interior of the United States, including five of moment magnitude (Mw) ≥ 5.0 in 2011 alone.
Concurrently, the volume of fluid injected into the subsurface related to the production of unconventional resources continues to rise. Here we identify the largest earthquake potentially related to injection, an Mw 5.7 earthquake in November 2011 in Oklahoma. The earthquake was felt in at least 17 states and caused damage in the epicentral region. What is fracking and why is it controversial? Drilling companies suggest trillions of cubic feet of shale gas may be recoverable from underneath parts of the UK through a process known as "fracking".
Hydraulic fracturing, or fracking, is a technique designed to recover gas and oil from shale rock. But how does it work and why is it controversial? What is fracking? Fracking is the process of drilling down into the earth before a high-pressure water mixture is directed at the rock to release the gas inside. Report Warns Of Human-Induced Earthquakes. A report on United States earthquake risk areas reveals what seismologists have gradually come to suspect: The interior states are now more likely to experience earth tremors than the famously quake-prone cities of the West Coast.
Most of the time, human activity is to blame, but the question remains—how much damage can human-induced earthquakes do? The U.S. Geological Survey (USGS) has for the first time attempted to estimate the scale of earth movement that human activities generate. It acknowledges that oil and gas drilling operations are setting off thousands of earthquakes. Oil and gas operations could trigger large earthquakes.
The U.S.
Geological Survey (USGS) has taken its first stab at quantifying the hazard from earthquakes associated with oil and gas development. The assessment, released in a preliminary report today, identifies 17 areas in eight states with elevated seismic hazard. Promiscuous women cause earthquakes, Iran cleric says. Survivors of an earthquake search debris in Bam, Iran, in late 2003.
That quake killed tens of thousands of people. "When promiscuity spreads, earthquakes increase," hard-line cleric says in videoVideo on YouTube apparently shows cleric leading Friday prayers in TehranIran suffers regular earthquakes, including one that killed tens of thousands in 2003.
