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 a mix of vulnerable and earthquake-resistant construction. The predominant vulnerable building types are unknown/miscellaneous types and heavy wood frame construction.
Recent earthquakes in this area have caused secondary hazards such as landslides that might have contributed to losses.
