In order to evaluate the ultimate usefulness of the Earth as a gravitational wave detector Professor Boughn will compute the excitation of the quadrupole modes of the Earth by terrestrial mechanisms, the most important of which are earthquakes and atmospheric/ocean pressure loading. This research will primarily involve careful modeling of the latter mechanism and then comparing the results with seismic data taken in earthquake quiet times. The results of this analysis will not only provide an evaluation of the ultimate sensitivity of the Earth to gravitational waves but should also provide interesting geophysical information about excitation mechanisms of the modes of vibration of the Earth.

为了评估地球的最终用途 作为引力波探测器， 地球四极模的激发， 其中最重要的是 地震和大气/海洋压力负荷。 这 研究将主要涉及后者的仔细建模 并与地震资料进行了对比 在地震平静的时候。 该分析的结果 不仅能提供一个最终的 地球对引力波的敏感性，但应该 还提供了有趣的地球物理信息， 地球振动模式的激发机制。
