Past events with this alert level have required a regional or national level response. Yellow alert level for economic losses. Some damage is possible. Estimated economic losses are less than 1% of GDP of the Islamic Republic of Iran. Structures: Overall, the population in this region resides in structures that are highly vulnerable to earthquake shaking, though some resistant structures exist. The predominant vulnerable building types are adobe block and unreinforced brick with timber floor construction. Historical Earthquakes (with MMI levels): Date (UTC) Dist. (km) Mag.
