There are about 300 000 people living within 100 km (62 miles).

2 000 people are estimated to have felt moderate shaking and 17 866 000 light.

The USGS issued a Green alert for shaking-related fatalities and economic losses. There is a low likelihood of casualties and damage.

Recent earthquakes in this area have caused secondary hazards such as landslides that might have contributed to losses.
