A comparison is presented between explosion‐generated teleseismic P signals from single events of comparable magnitude in the Tuamotu Islands, Nevada, and E. Kazakh recorded by the Wake Island Hydrophone Array. Spectral analysis of these signals indicates that attenuation (presumably under the source) is greatest for the Tuamotu travel path and least for the E. Kazakh travel path. The high frequencies (> 3 Hz) present in E. Kazakh signals, which enhance the detectability of these signals on the ocean bottom near Wake (where noise levels are low in this range), are generally absent in signals from Nevada and the Tuamotus.
