2004年9月5日日本纪伊半岛附近发生M7.4地震，在2004年4月新设计和建立的GPS浮标处记录到了海啸，该浮标距离日本西南部室户岬约13公里。海啸在到达室户岬尖端最近的验潮站前约8分钟到达浮标。初步源模型的基础上预测的海啸记录显示出良好的协议（均方根2.7厘米）与观测到的GPS记录。这表明GPS浮标观测不仅可用于海啸预警系统，而且可用于精确确定海啸源。
A tsunami due to the 2004 M7.4 September 5th earthquake off of the Kii peninsula, Japan, was recorded at the GPS buoy newly designed and established in April 2004, about 13 kin off of the Muroto Promontory, southwestern Japan. The tsunami arrived at the buoy about 8 minutes before its arrival to the nearest tide gauge station at the tip of the Muroto Promontory. The predicted tsunami record based on preliminary source model shows excellent agreement (rms 2.7 cm) with the observed GPS record. This demonstrates that GPS buoy observations can be used not only for a tsunami warning system, but also for precise determination of the tsunami source.
