Position: 10.008°S 161.533°E – Depth: 64.5 km
Jamaseis heliocoder trace of AM.R8C73.00.SHZ and PE.PSUB.HHZ. The P wave arrivals are annotated. At this distance direct S waves are not present as they cannot pass through the liquid outer core. As a result there isn’t much to see on R8C73 as it is mostly sensitive to the higher frequency body waves (P and S). On PSUB however you can see long period surface waves starting at about 20:02. These continue for another 90 minutes.
