据一项新的研究报告,智利的部分地区早就应该发生一场今年早些时候所经历的大地震;这场迟迟没有发生的大地震发生前有过持续很久的一系列地震活动,这或是大地震的触发机制。这一持续良久的地震活动是一种所谓的慢滑事件的一部分;该缓慢滑动是一种地震样的事件,它会在为期数月甚至数年的时期内释放能量,而不是在几秒钟或数分钟内释放能量。今年4月 According to a new study, some large earthquakes experienced earlier this year should have taken place in parts of Chile for a long time before this great earthquake that lasted Or the trigger mechanism of a large earthquake. This prolonged seismic activity is part of a so-called slow-slip event, a seismic event that releases energy over periods of months or even years instead of seconds Or within a few minutes to release energy.
