Hydrodynamic Echoes: An investigation of Seiche Activity Following the March 28, 2025 Myanmar Earthquake

This article presents a unique dataset of standing waves, also known as seiches, observed in swimming pools and other small bodies of water (ponds, lakes, fish tanks etc.) near the epicenter of the M7.7 Myanmar earthquake and in neighboring countries. While this phenomenon of seiching is not frequently documented on such a scale, these waves may provide valuable insights. Although this dataset is certainly not exhaustive due to its reliance on reported observations (versus available observations), these collected observations are crucial to better understand the initiation of seiches due to earthquake ground motions and their dependence on local geological and geomorphological characteristics. This study aims to contribute to the field by providing a unique collection of records linked to this seismic effect.
