地壳形变观测可以通过仪器测量观察，用激光测量地表标志之间的距离变化；用水准仪测量地面固定点之间的高差变化等。通过这些数据，为地震预测提供依据。直接观测地壳形变,不论在研究地球动力学、地壳构造运动和地壳稳定性评价,以及研究地壳形变在地震形成过程中所起的作用,都具有重要意义。
地倾斜连续观测是地壳形变观测研究中重要内容。
Continuous ground tilt observation is important in crustal deformation studies.
钻孔应变观测正在成为一种与测震和GPS相提并论的地壳形变观测。
Borehole strain observation has been admitted, following seismometry and GPS, a most important means to monitor real-time crustal deformation.
日本的地震预测系统现在已经在观测地壳活动和形变，也许它们还要将海潮纳入观测范围。
Japan's earthquake forecasting program, which monitors factors such as seismic activity and crustal deformation, may eventually watch tidal activity as well.
