Geophysical characterization of salt caverns for compressed air energy storage using microtremor array measurements
Peng Guan
Accurate characterization of salt caverns is a prerequisite for evaluating the feasibility of Compressed Air Energy Storage (CAES), yet high-noise urban environments pose challenges for conventional active-source geophysical methods. To address this, our study utilized Microtremor Array Measurements (MAMs) based on the Spatial Autocorrelation (SPAC) method to characterize deep salt caverns for a CAES project in Yunnan, China. The results reveal dissolution features and morphological asymmetry wi
