Seismo-acoustic coupling in microseismic events: Evidence from the Deccan Volcanic Province, Maharashtra, India

The Deccan Volcanic Province (DVP), traditionally classified as a stable continental region, exhibits persistent low-magnitude seismicity that challenges conventional tectonic paradigms. Recent microseismic events in the Sangola tehsil, Solapur district, Maharashtra, have been accompanied by audible acoustic phenomena, providing an opportunity to investigate seismo-acoustic coupling mechanisms. We conducted a comprehensive analysis integrating instrumental seismic data from the National Center for Seismology (India) with systematic documentation of public acoustic reports. Seismic events were analyzed for magnitude-depth relationships, temporal patterns, and frequency characteristics. Acoustic reports were systematically classified and correlated with instrumental records. Four documented earthquakes (M 2.2-3.1) occurred at shallow depths (5-10 km) between 2023-2025, all accompanied by audible
