智利是世界上部分大地震的发生地:那里大概平均每十年就会发生一次8级地震。这些地震都发生在俯冲带:有的发生在南美和Nazca板块之间的界面上,称为板间破裂;有的发生在Nazca俯冲板块内部,称为板内事件。每个世纪都会发生几次巨大的板内、板间地震,这些地震只需一次剧烈震动就会 Chile is the site of some of the major earthquakes in the world: an average of a magnitude 8 earthquake occurs every ten years there. These earthquakes occur in the subduction zone: some occur at the interface between South America and the Nazca plate and are called intraplate ruptures; others occur inside the Nazca subduction plate and are known as intraplate events. Every century, there will be a few huge intra-plate and inter-plate earthquakes, these earthquakes will only need a violent vibration
