According to the USGS, the epicenter was located 31.6 km (19.7 miles) NNE of San Agustín Chayuco (population 0), 54.5 km (33.9 miles) NE of Pinotepa Nacional (population 25 669), 69 km (42.9 miles) S of Heroica Ciudad de Tlaxiaco (population 14 608), and 80.7 km (50.1 miles) E of Ometepec (population 17 801), Mexico.
A very strong and shallow earthquake registered by the USGS as M7.2 hit Oaxaca, Mexico at 23:39 UTC (17:39 local time) on February 16, 2018. The agency is reporting a depth of 24.7 km (15.3 miles). EMSC is reporting M7.2 at a depth of 10 km (6.2 miles). Mexico's SSN is reporting M7.2 at a depth of 12 km (7.4 miles). A yellow alert was issued for shaking-related fatalities and economic losses.
There are 1 100 000 people living within 100 km (62 miles) and 11 000 within 10 km.
16 000 people are estimated to have felt very strong shaking, 439 000 strong, 1 322 000 moderate and 34 449 000 weak.
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 GDP of Mexico.
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 mud wall and adobe block with concrete bond beam construction.
Recent earthquakes in this area have caused secondary hazards such as tsunamis and landslides that might have contributed to losses.
At 02:01 UTC, the Governor of Oaxaca said there are no reports of people killed. "However, places like National Pinotepa, Río Grande, Jamiltepec and San José del Progreso report damage in dozens of buildings."
