Analyzing Tangible and Intangible Effects of KermanshahEzgeleh Earthquake on Landforms

Earthquakes are one of the most important environmental hazards that always lead to a lot of damage. In addition to the effects that earthquakes on residential areas, they also have many tangible and intangible effects on landforms that can cause hazards. Due to the importance of the issue, the current study investigates the tangible and intangible effects of herd earthquakes on landforms in the Ezgeleh region. The research data includes the 30-meter SRTM digital elevation model, digital data layers, Sentinel 1 images, and information obtained through field visits. The most important research tools include ARCGIS software (for mapping and final output) and GMT (for radar interference). This research has been done in 3 stages. In the first stage, using the radar interferometry method, the amount of vertical displacement of the area is calculated. In the second stage, the vertical displacement of the landforms of the region has been evaluated and in the third stage, the tangible effects of the earthquake on the landforms of the region have been investigated. The results of the research indicate that under the influence of earthquakes, the area had a displacement of between -613 and +917 mm. Due to the vertical displacement that has occurred in the region, the landforms of the region have also faced a lot of displacement so that the plains in the region have been affected by this displacement in which the highest displacement with 382 to 917 mm elevation is related to Zahab plain. Unlike the plains of the region in which the movement and changes have been mostly imperceptible, the slopes located in the region, in addition to the imperceptible effects, have also encountered many tangible effects. Therefore, many slopes of the region, including the slopes located near the villages of Ramaki Ramazan, Meleh Kaboud and Ghouchbashi have lnadslice, as well as the slopes near Piran waterfall and Baba Yadegar valley have Debriz.
