求帮忙啊，英语作文关于火山喷发的，要带翻译，最好不要太难，简单点，高一水平

After 9,000 years of silence, Chile's Chaiten volcano erupted, generating what may have been a "dirty thunderstorm." These little-understood storms may be caused when rock fragments, ash, and ice particles collide to produce static charges--just as ice particles collide to create charges in regular thunderstorms. The eruption, which continued off and on for months, forced the evacuation of thousands of residents and cattle from this corner of Patagonia.

　　智利伴随闪电暴风雨的火山爆发场景，在经过长达9000年的沉寂后，智利的紫藤(Chaiten)火山首次爆发。正如图片所示，火山爆发时伴随着雷电和暴风雨，这种很难理解的现象可能是当火山爆发时的岩石碎片、灰尘和冰粒相互碰撞产生强大静电造成的。这次断断续续长达几个月的火山大爆发也使成千上万的民众被迫转移。
