Oklahoma Earthquake Officially Largest in State's History
The 5.6 magnitude earthquake that rattled Pawnee, Oklahoma Saturday morning has been classified as largest in state history, according to the U.S. Geological Survey (USGS).
The September 3, 2016 Oklahoma earthquake occurred as the result of shallow strike-slip faulting about 15 kilometers northwest of the town of Pawnee.USGS
Earlier reports had matched the Labor day weekend temblor with the November 2011 Prague quake. However, USGS geophysicist Daniel McNamara confirmed to KOCO on Monday that the Pawnee earthquake was about 10 percent larger, even though it fell within the same 5.6 magnitude range.
The Midwestern state is not previously known for seismic activity, however the disposal of wastewater produced from fracking has led to the region's alarming increase in magnitude-3 or larger earthquakes in recent years. Scientists have dubbed this phenomenon as "induced earthquakes" as they are triggered by human activities as opposed to "natural" seismicity.
The USGS is currently investigating whether or not Saturday's earthquake—which occurred 25 miles north of the world's largest oil-storage complex in Cushing, Oklahoma—was triggered by wastewater fluid injection from oil and gas production in the area.
If the Sept. 3 quake was indeed triggered by wastewater injection, Oklahoma will set the record for the largest manmade earthquake in history. This dubious record is currently held by British Columbia, Canada, which felt a 4.6-magnitude last year due to fluid injection from the fracking process.
Oklahoma Gov. Mary Fallin declared a state of emergency for Pawnee County following the quake that was felt from Nebraska to Texas. The Oklahoma Corporation Commission (OCC), the state agency tasked with regulating the oil and gas industry, also immediately shut down all disposal wells within a 725-square mile in the Arbuckle shale formation. Commission spokesman Matt Skinner told Bloomberg that this is the first time the regulator issued the mandatory measure.

According to KOCO, the Oklahoma Geological Survey said on Monday that the Pawnee quake could have been years in the making, adding that earthquakes can happen years after wastewater is disposed into the ground. Ominously, this implies that wastewater that has already been pumped into the ground could trigger future quakes.
It's important to note that the OCC did not shut down every well in the state. Oklahoma is currently home to 3,200 active disposal wells, according to data from the OCC.
In March, the USGS released a startling report showing that approximately 7 million people live and work in areas of the central and eastern U.S. with potential for damaging shaking from induced seismicity. There are roughly 40,000 disposal wells nationwide, the U.S. Environmental Protection Agency says.
Environmentalists have called on a ban on fracking due to the recent spate of Oklahoma earthquakes.
"The 5.6 magnitude earthquake that occurred in Oklahoma and was felt throughout the Midwest this morning threatened countless homes and businesses, and put lives at risk," Wenonah Hauter, the executive director of Food & Water Watch, said.
"But it could have been prevented. This earthquake, and hundreds of others like it over the last few years, are the direct result of the underground disposal of fracking wastewater. There can't be fracking without disposing of fracking waste, and there is no safe way to do so. This is just one of many reasons why fracking is inherently dangerous and must be banned."
Earlier this year, the Sierra Club and Public Justice filed suit against four of the primary culprits for wastewater disposal, citing that it causes an "imminent and substantial endangerment" to public health and the environment in violation of the Resource Conservation and Recovery Act.

By 2030, almost a third of all the energy consumed in the European Union must come from renewable sources, according to binding targets agreed in 2018. Sweden is helping lead the way.

Naturally Warm<p>54% of Sweden's power comes from renewables, and is helped by its geography. With plenty of moving water and 63% forest cover, it's no surprise the <a href="https://sweden.se/nature/energy-use-in-sweden/#" target="_blank">two largest renewable power sources</a> are hydropower and biomass. And that biomass is helping support a local energy boom.</p><p>Heating is a key use of energy in a cold country like Sweden. In recent decades, as fuel oil taxes have increased, the country's power companies have turned to renewables, like biomass, to fuel local 'district heating' plants.</p><p>In Sweden these trace their <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank">origins back to 1948</a>, when a power station's excess heat was first used to heat nearby buildings: steam is <a href="https://www.sciencedirect.com/topics/engineering/district-heating-system" target="_blank">forced along a network of pipes</a> to wherever it's needed. Today, there are around 500 district heating systems across the country, from major cities to small villages, providing heat to homes and businesses.</p><p>District heating used to be fueled mainly from the <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140" target="_blank">by-products of power plants</a>, waste-to-energy plants and industrial processes.

Energy ‘Prosumers’<p>But Sweden doesn't stop at village-level heating solutions. Its new breed of energy-generation takes hyper-local to the next level.</p><p>One example is in the city of Ludivika where 1970s flats <a href="https://www.buildup.eu/sites/default/files/content/transforming-a-residential-building-cluster-into-electricity-prosumers-in-sweden.pdf" target="_blank">have recently been retrofitted with the latest smart energy technology</a>.</p><p>48 family apartments spread across 3 buildings have been given photovoltaic solar panels, thermal energy storage and heat pump systems. A micro energy grid connects it all, and helps charge electric cars overnight.</p><p>The result is a cluster of 'prosumer' buildings, producing rather than consuming enough power for 77% of residents' needs. With <a href="http://www.diva-portal.org/smash/get/diva2:1232060/FULLTEXT01.pdf" target="_blank" rel="noopener noreferrer">high levels of smart meter usage</a>, it's a model that looks set to spread across Sweden.</p>

This story is published as part of StudentNation's "Vision 2020: Election Stories From the Next Generation" reports from young journalists that center the concerns of diverse young voters. In this project, working with Dr. Sherri Williams, we recruited young journalists from different backgrounds to develop story ideas and reporting about their peers' concerns ahead of the most important election of our lives. We'll continue publishing two stories each week over the course of September.
