Detection of Earthquake Infragravity and Tsunami Waves With Underwater Distributed Acoustic Sensing

Geophysical Research Letters, Volume 51, Issue 2, 28 January 2024.
Abstract Underwater Distributed Acoustic Sensing (DAS) utilizes optical fiber as a continuous sensor array. It enables high‐resolution data collection over long distances and holds promise to enhance tsunami early warning capabilities. This research focuses on detecting infragravity and tsunami waves associated with earthquakes and understanding their ...
