Surveys of multichannel surface waves and horizontal to vertical spectral ratios were conducted at wharf No. 25 of the port, which suffered severe damage. An investigation of the extent of liquefaction is described, and descriptions of the seismic displacement-induced cracking of the caisson are provided. This study comprehensively integrates the observed geotechnical engineering-related disasters at Hualien Port caused by the earthquake. Through the on-site investigations and measurements, the interpreted information serves as a valuable reference for devising strategies in the event of future seismic events.falseGeotechnical reconnaissanceGravelly soilsPort structureSoil liquefaction[SDGs]SDG11journal article10.1016/j.soildyn.2025.1096132-s2.0-105009657366
