浅层岩体有韧度,可减缓断裂。
The effect is to give seismologists a tool they can use to make an instant estimate of anearthquake s depth and thus, if it is submarine, the risk of its creating a big tsunami.
地震学家可据此迅速估算地震深度,如果是海洋地震,还能估算地震是否引发强烈海啸。
The system Dr Newman and Mr Convers have developed taps into hundreds of seismicmonitoring stations around the world.
纽曼博士与康弗斯先生研发的新系统接入了世界各地几百所地震监测站。
When an earthquake is detected, the software immediately looks at the size of the tremorand the location of its epicentre.
当检测到地震时,该系统软件立即测算地震规模与震中位置。
If the quake s magnitude is greater than 6.5 and the epicentre is underwater, it thenrequests information from the relevant stations on how long the earthquake took frombeginning to end.
如果级数超过6.5级且震中位于水下,系统则要求相关监测站报送地震全程持续时间。
That allows it to work out how quickly energy was released by the earthquake, and thushow fast the rupture propagated.
这一信息可帮助计算地震能量释放速度,并以此计算岩层断裂速度。
