Solving a Seismic Mystery With the Audio From a Diver's Camera: A Case of Shallow Water <i>T</i>‐Waves in the Persian Gulf

Abstract Sparse offshore coverage of seismic networks has hindered detailed studies submarine earthquakes and their associated hazard. We present results our analysis a diver's recording acoustic signals from an M L = 5.6 earthquake in the Persian Gulf. model as set several shallow water T phases frequency group velocity which are determined by bathymetry. show that audio track this can provide reliable estimates location moment. also reported shaking southern Gulf, &gt;170 km source small could result waves traveling through entire width basin. Our point to rudimentary affordable underwater microphones similar those used divers' cameras tools build efficient, low‐cost for study events early warning.
