“…The unique geological environmental conditions of this region provide a favourable setting for natural disasters, including landslides. Tehran province covers an area of 13,690 km 2 , with elevations ranging from 760 to 4360 m (Baftipour et al., 2022). The maximum vertical elevation difference is 3600 m, and the slope of the land is from north, west, and east to the south (Baftipour et al., 2022).…”

Landsliding and slope instability pose significant risks to human settlements and infrastructure. This study aims to develop a landslide susceptibility map for the mountainous regions of Tehran province, Iran. The rock engineering approach was employed at a regional scale, utilizing a database of regional landslides. The semi‐quantitative Rock Engineering System method was applied, considering 10 conditioning factors. The model was validated using historical landslide data, showing strong correlation. The majority of landslides occurred within medium and high susceptibility zones. Geological units, particularly the Karaj Formation's claystone layers, displayed a clear association with landslide susceptibility. The rock engineering approach yielded a highly accurate susceptibility map. Findings can inform future territorial planning in the area.

“…The values of Mmax in Table1were calculated using 4 empirical relationships (with equal weight)(Ambraseys and Jackson, 1998;Nowroozi, 1985;Wells and Coppersmith, 1994;Zare, 1995). Regarding the faults same as Salmas, the value of Mmax was determined according to related earthquakes.1-Zare, 1995; 2-Wells & Coppersmith, 1994; 3-Nowroozi, 1984; 4-Ambraseys & jacson, 1998In drawing and mapping the faults, it was attempted to bring together all previous studies(Ambraseys, 2009;Ambraseys and Jackson, 1998;Baftipour et al, 2022;Barka et al, 2002;Basili et al, 2013;Giardini et al, 2013;…”

Earthquakes are one of the natural hazards that have caused many casualties and financial losses around the world. This is why earthquake risk analysis studies need to be conducted more seriously. Iran is located in one of the seismogenic regions of the world, the Himalayan-Alpine belt, which is subject to many earthquakes every year. The Arias intensity, as one of the important seismic parameters, helps in seismic hazard analysis, and can be used to estimate structural performance, slope stability, and liquefaction during an earthquake. In this study, the tectonics and seismotectonics of the region of Khoy in northwestern Iran were investigated, and the location of future earthquake was determined. Next, Arias intensity’s maps for return periods of 475, 975 and 2475 years were prepared. The effect of shear wave velocity (Vs30) was also considered during the analyses. The most dangerous area, who’s located at one of future earthquake locations, and also has the potential of resonance and liquefaction, is the northeast of the Salmas fault. Evidently, other than the distance from the fault, the intensity of the earthquake is affected by changes in Vs30. It means, in some cases, at more distant points from the seismic source, the intensity even increases. This shows the importance of the effects of geological conditions on the estimation of intensity.
