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 vulnerable to earthquake shaking, though resistant structures exist. The predominant vulnerable building types are informal (metal, timber, GI etc.) and heavy wood frame construction.

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