Powerful earthquake near Salina Cruz, Mexico (Oaxaca)

Earthquake Report comment :
Epicenter of the earthquake is only 40 km from the town of Salina Cruz in the province of Oaxaca.
De pending on the data source the hypocenter of this earthquake is located in between 10 km and 58 km (a big difference).
Salina Cruz has a population of 73,468 (latest census).
San Mateo de Mar, even a little closer to the epicenter, has a population of 5,441.
Both populated centers lie in the immediate vicinity of the subduction zone where the Cocos plate is diving under the Caribbean plate, thus creating a dangerous earthquake zone.
This area has regular earthquakes and people are used to shocks from time to time. Earthquake-Report.com predicts no damage or injuries from this earthquake, although every earthquake can be felt differently.
This earthquake is hardly reported by the Mexican press. All the spots are still on the aftermath of tropical storm "Karl" who is claiming at least 18 victims.

Wikipedia info on Salina Cruz :
Salina Cruz is a major seaport on the Pacific coast of the Mexican state of Oaxaca. It is the state's third-largest city and is municipal seat of the municipality of the same name. It is part of the Tehuantepec District in the west of the Istmo Region. The city had a 2005 census population of 71,314 persons, while its municipality, with an area of 113.55 km² (43.84 sq mi) had a population of 76,219, the state's fourth-largest municipality in population. The port expanded in the late 19th century due to its location at the southern terminus of the Tehuantepec National Railway, which carried freight across the Isthmus of Tehuantepec. It is situated near the mouth of the Río Tehuantepec, on the open coast of the Isthmus of Tehuantepec, and has no natural harbour. There was only a small Native American village before Salina Cruz was chosen as the Pacific terminus of the railway, whereupon a modern town was laid out and built on adjacent higher ground.
