地震触发滑坡
定义
由地震震动引发的土壤和岩石沿坡向下运动。滑坡可能掩埋整个社区，造成的伤亡有时甚至超过震动本身。
示例
2008年四川地震在山区引发了超过60,000次滑坡。

常见问题解答
震中是地表上位于震源（地震破裂开始处）正上方的点。通常以经纬度坐标报告。最强的震动通常发生在震中附近，但当地土壤条件和断层几何形态可能使最大损害区域发生偏移。
地震仪（地震计）是检测和记录地震波引起的地面运动的仪器。现代宽频带地震仪可以检测到比原子宽度还小的运动。全球地震仪网络使科学家能够在几分钟内确定地震的位置和震级。
P波（纵波）是通过岩石传播最快的压缩波，最先到达地震台站。S波（横波）到达较晚但引起更大的地面震动。P波可以通过固体、液体和气体传播；S波只能通过固体传播。两者之间的时间差有助于确定地震的距离。
震源是地球内部地震破裂开始的点。它由经度、纬度和深度来描述。震源与其正上方地表之间的垂直距离即为地震深度，这对地表感受到的震动强度有很大影响。
地震学是研究地震和地震波在地球内部传播的科学学科。它包括地震检测、定位和特征描述、地球内部结构、地震危险性评估和地震工程。地震学家利用全球地震仪网络的数据来研究这些现象。
