1、Natural gas can be used for energy. One of the ways companies that get it is called hydraulic fracturing, or fracking. Its when engineers use water and chemicals to crack open rocks deep underground, and that releases those natural gases.Theres a debate happening in Youngstown, Ohio. Its not about f
2、racking itself. Its about what happens to the water and chemicals afterward. and its launched a scientific investigation. Poppy Harlow has the details on this for us.We want to know whats causing the earthquake.Youngstown residents are demanding answers about why their houses shook on New Years Eve.
3、Ive never heard - had an earthquake in my whole life.It was frightening.I thought a jet airliner crashed on the side of my house.It was the biggest of 11 earthquakes here since mid-March. And get this: scientists tell us they think theyre manmade.This is the New Years Eve earthquake.Seismologist Joh
4、n Armbruster says the 4.0 quake was likely triggered by this disposal well, which injects wastewater from fracking and oil and gas drilling at intense pressures, nearly 9200 feet underground.Injecting this much waste is disrupting Mother Nature. And Mother Nature, in this one case, is biting back.Th
5、e company, D and L Energy, says proximity alone does not prove causation.Channels one, two, and three are -Ohio called on Armbruster to help figure out whats causing all the earthquakes -You only need one disc.and closed five nearby disposal wells indefinitely.Its possible that theres induced seismi
6、c activity, so thats one possibility.Manmade earthquakes?Correct, but we dont have conclusive proof yet.There are more than 170 of these wells across Ohio.We wanted to understand how this process really worked, so were getting a rare look at these massive waste tanks,and then how it is all injected
7、deep into the earth.Trucks unloading the two tanks, then it is going through a filter and then injected down a hole. Were putting it exactly where the federal government says to put it.It is mostly saltwater, but also a small amount of chemicals from the frack fluid used to break apart the shale.How
8、 much drilling wastewater is being pumped deep into the earth here?Two thousand barrels a day approximately.Ive lived here about 42 years. Weve never had an earthquake like that.A proponent of fracking for the jobs it brings to this depressed economy, Youngstowns mayor is now worried.When you feel u

10、 the past two decades for the state of Ohio.Scientists hope theyre a little closer to solving a historic maritime mystery. This is the remains of the H.L.Hunley. It was a Confederate submarine from the U.S. Civil War. In fact, this is the first sub in history to sink an enemy warship.But in 1864, th
11、e Hunley sank, too, and nobody knows why. It was pulled out of the water about 12 years ago. The truss that pulled it out was removed for the first time last week. One researcher said being able to see the Hunley without the truss is like looking at the sub for the first time. Hes hoping this new vi

For CNN Student News, Im Carl Azuz, and we will see you tomorrow. 天然气可用于能源。公司获得它的方法之一是液压抽取或者之类的程序。当工程师使用水和化学药品炸开深埋地下的岩石时,大自然的这种气体被释放。俄亥俄州最近发生一种争论。这不是关于抽取。而是之后的水和化学药品。为此而展开了科学研究。请看博比?哈罗带给我们的详细报道。我们想要知道是什么导致了这次地震。扬斯敦的居民要
15、求回答他们的房屋为何在新年前夕震动。我在自己一生中都从来没有听说过地震。太可怕了。我以为是一架喷气式客机坠毁在我的房子旁边。这是3月中旬以来最严重的一次地震。看看这个:科学家告诉我们,他们就认为这是臆想出来的。地震发生在新年夜。地震学家约翰?阿贝斯表示这次4.0级的地震起因是处理井的缘故,强烈的压力将污水带进了地下9200英尺中的石油和天然气开采中。这种浪费现象无疑是破坏大自然。而大自然母亲,在这种情况下,开始了复仇。D&L能源这家公司表示独自一人并不能证明这种因果关系。频道一、二、三俄亥俄州呼吁阿贝斯帮助找出是什么因素导致了地震。你只需要一张盘。完全关闭附近的5个处理井即可。这是可能的,可以
16、诱发地震活动,所以这是有可能的事。人造地震?正确,但我们没有确凿证据。而在俄亥俄州有超过170个这样的处理井。我们想了解这个过程如何工作,所以我们得看看这一罕见的巨大的浪费的油罐,然后看看它如何到达深深的地底。卡车卸下两个燃料槽,那么它将会经历过滤,然后注入到一个洞中。我们把它放在联邦政府称其为确切的地方。大多是盐水,而且少量的化学物质用于分裂页岩的流体。这深不见底的地方要抽掉多少废水?一天大约二千桶。我在这里已经住了约42年。我们从未有过这样的地震。这样的工作为这里不景气的经济带来了就业机会,而最近市长正在担心。如果你在自己的房子感到不安全,那么这就是非常严重的情况。工作的繁荣导致巨大的需求
17、，更多的处理井被许可。州代表鲍勃?哈根呼吁暂停俄亥俄州的所有注射井。它会停止俄亥俄州呈现自己曾经在过去二十年间从未有过的经济发展的最佳机会。科学家们希望他们更进一步接近解开一个历史性的海中奥秘。这就是Hunley H.L.的遗迹。这是一艘来自美国内战的联邦潜艇。事实上,这是历史上第一艘击沉敌方舰船的潜艇。但在1864年,Hunley沉没,没人知道原因。约12年前它终于浮出水面。上个星期它首次被打捞得见天日。一位研究人员表示第一次看到潜水艇Hunley没有桁架结构。他希望这个新观点会给这艘船究竟发生了什么事带来新线索。今天的最后余兴节目为您带来的是,我们可能永远都不会知道为什么鸡会过马路。但是我们知道谁能帮她阻拦交通。大家向索菲娅问好,她是一位纽约最新的十字路口守卫。她自愿工作最近只有一个条件:那就是索菲能工作了。她携带的迷你停止标志是专门是给犬类准备。苏菲与学生的行程遍及全国的街道。你可能会想知道是什么品种最适合这项工作的。苏菲的血缘部分来自德国牧羊犬, 部分拉布拉多和100%的护卫狗。所以你最好在她面前抢行。今天的节目就此结束。这里是CNN学生新闻,我是卡尔?阿祖兹,我们明天再见。.
