The epicenter was located 8.4 km (5.2 miles) E of Sullana (population 160 789), 9.6 km (6 miles) SSE of Querocotillo (population 25 396), and 31 km (19.2 miles) N of Piura (population 325 466), Peru.

There are 1 680 000 people living within 100 km (62 miles).

315 000 people are estimated to have felt strong shaking, 1 013 000 moderate, and 1 157 000 light.

The USGS issued a Yellow alert for shaking-related fatalities. Some casualties are possible and the impact should be relatively localized. Past events with this alert level have required a local or regional level response.
