Abstract In this research, we used the 2006–2024 seismic catalog from the Iranian Seismological Center for a comprehensive analysis of the seismic ity parameters (b -value, the magnitude of com pleteness (MC), Fractal Dimension (DC), Seismic Moment (M0), and seismic quiescence (Z -value)) in the vicinity of Mw 6.2 Murmuri Earthquake of August 18, 2014, in the Zagros region of Iran. The MC exhibits spatial heterogeneity, with values rang ing from 2.0–2.5 near Dehloran to 3.0–3.5 near the Mountain Front Fault (M.F.F.), reflecting detection challenges in complex fault zones. Spatial b -value distribution indicates low values near the main shock epicenter and M.F.F., suggesting high-stress accumulation. The DC -value shows higher values near the epicenter, reflecting clustered seismicity. An orthogonal regression analysis reveals a strong negative correlation (r = -0.71) between b-value and DC -value in the region. The Z -value distribution in early 2014, using a 2-year time window, identifies significant quiescence near the epicenter, a precursor to the mainshock, transitioning to post-event acti vation. The spatial distribution of Z -values exhib its a complex pattern, with lower values (z ≈ − 1.0 to − 1.5) concentrated near the Murmuri epicenter, indicating a moderate decrease in seismic activ ity relative to the reference period. These findings highlight the M.F.F. as a high-hazard zone, with integrated parameter analysis enhancing precursory detection and post-event stress mapping.
