This study investigates the interaction between Rayleigh wave-groundwater-aquifer dynamics using seismic data. It finds a connection between groundwater level and the vertical motion of Rayleigh waves, and validates it at significant frequency bands. The findings are important for understanding aquifer behavior during seismic events and guiding groundwater management and earthquake readiness.
This study delves into the interplay of Rayleigh wave-groundwater-aquifer dynamics, utilizing seismic data from designated stations, particularly the magnitude 9 event on March 11, 2011 (02:46:23 PM epicenter), Tohoku earthquake, Japan. Auto spectra uncover significant peaks, linking groundwater level with the vertical motion of Rayleigh waves. High coherence between groundwater levels and seismogram vertical displacements confirms this connection. Coherence analysis validates it at the significant frequency bands. Groundwater storage coefficient estimation aligns with typical values of confined aquifers, ranging from 1.0E-05 to 1.0E-03. This consistency applies across different methods and other earthquake events, highlighting seismic impact. The findings enhance understanding of aquifer behavior during seismic events, aiding groundwater management and earthquake readiness in susceptible regions. Further research should expand datasets for coefficient accuracy. Insights advance aquifer behavior comprehension during seismic events, guiding groundwater management and earthquake readiness in prone areas.
