Из-за "сланцевого чуда" в США появилась еще одна сейсмоопасная зона

По теме сейсмики в Оклахоме добавлю: https://aftershock.news/?q=node/373544

... интересно бы послушать специалиста на эту тему. По идее небольшая вибрация должна приводить к "разрядке" напряжений в коре, а выходит что это наоборот землетрясения провоцирует...

По Оклахоме давно давно писал (перевел), интересная статья в моем блоге (тогда еще не участвовал в АШ):

Натуральная победа СМИ над разумом

“By including human-induced events, our assessment of earthquake hazards has significantly increased in parts of the U.S.,” said Mark Petersen, Chief of the USGS National Seismic Hazard Mapping Project. “This research also shows that much more of the nation faces a significant chance of having damaging earthquakes over the next year, whether natural or human-induced.”

Important Note: USGS scientists only distinguished between human-induced and natural seismicity in the CEUS. In the west, scientists categorized all earthquakes as natural. Scientists also used a different methodology in looking at the CEUS compared to the west.

While there are some areas of induced earthquakes in the western U.S., they don’t significantly change the regional hazard level compared to the much more abundant natural earthquakes. Therefore scientists just considered the historical catalog in the western U.S. and did not separate natural from induced earthquakes. Future research could take a more detailed look at induced seismicity in the west, including in California at The Geysers, Brawley or the Los Angeles Basin. 

Wastewater disposal is thought to be the primary reason for the recent increase in earthquakes in the CEUS. While most injection wells are not associated with earthquakes, some other wells have been implicated in published scientific studies, and many states are now regulating wastewater injection in order to limit earthquake hazards.

The assessment said that in that area, there is a 5 to 12 percent chance of a level six earthquake on the Mercalli index of intensity, which rates the potential for damage

Это его последствия))) 6 баллов по Меркалли - Ощущается всеми; испуганные люди выбегают на улицу; трескаются штукатурка и кирпичная кладка; сдвигается и переворачивается мебель; лопаются оконные стекла. Показательно состояние сейсмологии и отношения собственно к сейсмике в штатах)))

А это - что вообще такое эта геологическая служба

The new hazard model estimates where, how often and how strongly earthquake ground shaking could occur in the United States during calendar year 2016. The USGS chose this short timeframe of one year because induced earthquake activity can increase or decrease with time and is subject to commercial and policy decisions that could change rapidly.

The CEUS has experienced the most significant U.S. increase in seismic activity due to induced earthquakes in recent years. Therefore, in the 2016 forecast, scientists distinguish between human-induced and natural seismicity only for the CEUS. Scientists also used a historical catalog of seismic events leading back to the 1700s, putting a strong emphasis on earthquakes in 2015.

The USGS is the only federal agency with responsibility for recording and reporting earthquake activity nationwide and assessing seismic hazard. These maps are part of USGS contributions to the National Earthquake Hazards Reduction Program, which is a congressionally established partnership of four federal agencies with the purpose of reducing risks to life and property in the United States that result from earthquakes.

 

Короче говоря - мы пахали, я и трактор)))

The Geological Survey report also said the chances of a damaging natural earthquake had risen in some parts of the United States. Scientists noted an increase in the number of small tremors along the New Madrid fault, near Memphis, which in the early 1800s was the site of one of the nation’s largest earthquakes. The increase in tremors there has slightly raised the prospects of a larger quake, the scientists said 

Переводить надеюсь не надо? 

Я не знаю как 6 баллов можно не почувствовать. Живя в Казахстане помню землетрясение в 4,5 балла: люстра, раскачиваясь, била по потолку, из шкафов все вываливалось, поразбивались все вазы и вообще ощущения были не из приятных.

Я думаю тут землетрясения не так важны как отравление почвенных вод. Вот это реальная опасность.
