1、地震学潘明恩121150048 基地班地球物理学：以地球为研究对象的一门应用物理学。地震学：以地球介质的弹性差异为基础，研究地震波产生和传播规律。天然地震震源（focus)：发生地震的地方震中(epicentre)：震源于地面上的垂直投影震源深度(depth of focus)：震源至震中的距离震中距（distant of epicentre)：震中至台站的距离发震时刻(original time)：地震发生时间震级（magnitude）：地震释放的弹性波能量大小，根据地震图上记录地震波强度表征地震大小的无量纲标量地震成因：构造地震：由于构造力作用导致地下岩层断裂和错动造成的地震火山地震：火山
2、喷发前地下岩浆冲动，或在火山喷发时火山口内气体发生爆炸产生的地震诱发地震：人类活动导致地壳局部失稳导致的地震震源深度：浅源地震：震源深度不超过60Km 中源地震：震源深度61300Km 深源地震：震源深度超过300Km 震中距：地方震：100 km 近震：100 km 1000 km 远震：1000 km 地震波传播的基本规律在一般情况下，当作用力较小，且作用时间较短时，介质可以近似地看作为弹性介质。应力：反映物体内部一点处受力程度的力学量，定义为物体内部单位面积上所受的力。应力张量：xxxyxzyxyyyzzxzyzz线应变:L/L 体应变:V/V 剪切应变:l/l=1/2*tg 应变张量：

4、面附近，并沿地表或层面传播的波叫面波。瑞利波：在介质自由表面，由P波和 SV波耦合形成的面波。勒夫波：当低速层状介质覆盖于较高速度的半空间时，SH波在层内全反射叠加形成的面波。纵波波速2pV横波波速文档编码:CW6P4I3Y5M2 HV5W7E4T2T10 ZI3H3I1J3Y3文档编码:CW6P4I3Y5M2 HV5W7E4T2T10 ZI3H3I1J3Y3文档编码:CW6P4I3Y5M2 HV5W7E4T2T10 ZI3H3I1J3Y3文档编码:CW6P4I3Y5M2 HV5W7E4T2T10 ZI3H3I1J3Y3文档编码:CW6P4I3Y5M2 HV5W7E4T2T10 ZI3H3I1
