An Analysis of Vulnerability Indicators of Urban Settlements Against Earthquake (Case Study: Gorgan City)

Natural events such earthquake can cause to big damage especially growth population and increasing city-sitting and stopped extension city so decreasing city-damaging is a main aim to program city-making. The study surveys evaluation damaging of gorgan's buildings. Method of the study is describing-analyzing that knowing different ways to evaluate buildings that depend on building conditions. Studied zones, methods of field concepts that were used and analyzed by GIS, such spatial geostatistical analysis and studied interior by Kringing method to supply forecasting maps and evaluations with compactions ideal factors from damaging city-buildings at earthquake that 17.33 % of gorgan's zone has possibility of damaging and human events. Biggest zone of the zone that is old using invaluable material for buildings. Analyzed results showed that 25.58 % of gorgan's zone is based on 2800 number protocol that have less-damage that build at new houses at recent years.
