Rockfall geosite

Rockfall, downslope movement of loose rock materials, has been known as one of the hazardous geomorphological processes, which occurs due to various causes. Earthquake is the most important rock fall triggering agent. Field observations from throughout the Aras Geopark territory indicate that this region has experienced devastating historical earthquakes so that their effects are particularly noticeable in the western and northwestern parts of the area. Rock falls along the Jolfa to Poldasht Road and mainly around the Choopan Chapel enable us to confirm the occurrence of earthquakes in this region. Consequently, large blocks of red conglomerate have fallen from the Eocene sedimentary sequence of the northern slope of Alli-Bashi Mountain. This implies the potential for natural hazards to cause damage in the region and can be an alarm for local people.
