Studying the potential and risk of liquefaction zoning in the Saqqez unit (Iran-Kurdistan)

The phenomenon of liquefaction occurs in separated sand or silty soils. Symmetric or asymmetric settlement, a decline in the capacity of surface foundations and piles to support loads, and an increase in the lateral forces needed to safeguard structures are all effects of structural instability. During earthquakes, liquefaction can harm human infrastructure and alter the geomorphology of the earth's surface. It is crucial to identify locations susceptible to liquefaction in order to combat the damaging effects of this phenomenon. Zoning can be used to identify regions that are prone to liquefaction, greatly minimizing the amount of damage brought on by liquefaction during an earthquake. This identification may take the form of zoning, in which the risk tolerance of various places is assessed. This article presents the findings of research done on the zoning of liquefaction capacity in the province of Kurdistan. This zoning was carried out in accordance with the guidelines in the zoning handbook for geotechnical earthquake hazards and earthquake engineering. The findings of the investigations indicate that the plains of the Kurdistan Province have a danger potential that ranges from low to high, depending on the nature and texture of the deposits and the amount of subsurface water. This article's goal is to explain how Sanandaj's earthquake danger is zoned based on impact factors.
