The epicenter was located 42 km (26 miles) ESE of Molina (population 28 775), 49 km (30 miles) SE of Curicó (population 102 438), and 70 km (43 miles) E of Talca (population 197 479), Maule, Chile.
17 000 people are estimated to have felt very strong shaking, 150 000 strong and 3 819 000 moderate.
The USGS issued a Yellow alert for shaking-related fatalities and economic losses. Some casualties and damage are possible and the impact should be relatively localized. Past yellow alerts have required a local or regional-level response.
Estimated economic losses are less than 1% of Chile’s GDP.
Overall, the population in this region resides in structures that are resistant to earthquake shaking, though vulnerable structures exist. The predominant vulnerable building types are adobe block and rubble/field stone masonry construction.
Recent earthquakes in this area have caused secondary hazards such as liquefaction that might have contributed to losses.

There are no reports of damage or injuries.
