According to USGS PAGER, 1 000 people are estimated to have felt moderate shaking, 58 000 light and 23 000 weak.
There is no tsunami threat from this earthquake.
The USGS issued a Green alert for shaking-related fatalities and economic losses. There is a low likelihood of casualties and damage. Overall, the population in this region resides in structures that are moderately resistant to earthquake shaking. The predominant vulnerable building types are reinforced concrete frames with unreinforced brick infill.
Recent earthquakes in this area have caused secondary hazards such as landslides and liquefaction that might have contributed to losses.
Liquefaction triggered by this earthquake is considered unlikely. No significant landsliding is expected.
