摘要

In this study, the geophysical environment and earthquake dynamics of the Sabalan volcano are explored using MT inversion and advanced spectrum analysis. The magnetotelluric profile, approximately 12.98 km in length, oriented SW-NE, is located about 5.31 km west of Mount Sabalan. The Occam and Bostick algorithms have succeeded in inverting two-dimensional sections of electrical resistivity, indicating conductive fault-controlled paths FLM1 to FLM3, which are linked to hydrothermally altered sections with fluid movement. These paths are located above larger and highly resistive sections that correspond to large volcanic or intrusions which may act as a heat source in geothermal environments. In addition to geoelectric modeling and interpretation, we are examined amplitude spectra of local seismic data through two methods classical Fourier analysis and a formulation derived from quantum mechanics theory. By classical means, via Fast Fourier Transform, we obtain the traditional results, whereas the quantum approach grounded in the Schrödinger equation exhibits greater resilience to noise and reveals distinct resonance features at low frequencies ( 5–10 Hz ) that classical methods fail to resolve. These quantized energy provide novel insight on source processes and energy accumulation zones. The combination of MT and quantum spectrum analysis highlights the connection among structural geology, geothermal activity, and seismicity at Sabalan, carrying significant implications for risk evaluation and the exploration of geothermal resources.
