108 000 people are estimated to have felt very strong shaking, 206 000 strong, and 233 000 moderate.
The USGS issued an Orange alert for shaking-related fatalities. Significant casualties are likely and the disaster is potentially widespread. Past events with this alert level have required a regional or national level response.
Yellow alert was issued for economic losses. Some damage is possible. Estimated economic losses are less than 1% of GDP of Iran.
Overall, the population in this region resides in structures that are a mix of vulnerable and earthquake-resistant construction. The predominant vulnerable building types are adobe block and dressed stone/block masonry construction.
Recent earthquakes in this area have caused secondary hazards such as landslides that might have contributed to losses.
According to the governor of West Azerbaijan Province, Mohammad Sadegh Motamedian, the quake injured 528 people, of which 135 had to be admitted to hospital.
The quake and its aftershocks damaged 500 houses in 12 villages, completely destroying 50.
