除了备有灵敏的地震仪，地球物理监测站还将会使用一个装有温度计的探测器钻入地下20英尺（6米）以尝试着计算出温度随深度增加而升高的速度。

Along with sensitive seismographic equipment, GEMS will drill down about 20 ft. (6 m) with a thermometer-equipped probe, trying to figure out how quickly the temperature rises with depth.

另有各种装备可改变转轴速度及使钻头自动钻入工作件中。

Means are provided for varying the spindle speed and (on some machines) for automatically feeding the drill into the workpiece.
