There were at least five minor earthquakes measuring more than 4 degrees magnitude on the Oaxaca coast early Saturday.
The tremors occurred between 1 a.m. and 7:57 a.m., the National Seismological Service (SSN) reported.
The most intense tremors both measured 4.6. The first was recorded near Huatulco at 6:24 and the second near Puerto Escondido at 7:57.
The second most intense were 4.4 and 4.1, recorded at 3:50 and 6:57 a.m. near Salina Cruz and Huatulco respectively.
Another 4 magnitude tremor was reported at 5:45 a.m. near Salina Cruz.
Despite the frequency of the tremors, state Civil Protection officials did not report any injuries or property damage.
Oaxaca is one of the states with the highest seismic activity in Mexico, with 25% of the country’s earthquakes recorded here.
The activity is due to the convergent contact between two important tectonic plates, the Cocos plate and the North American plate.
The interaction between both takes place on the Pacific coast, in an area that goes from Chiapas to Jalisco.
The towns historically most affected by earthquakes in Oaxaca are Puerto Escondido, Pochutla, Puerto Ángel, Huatulco, Loxicha, Chacahua, Jamiltepec, Pinotepa Nacional, Ometepec and Miahuatlán.
The SSN recorded 111 earthquakes in Oaxaca during the first nine days of September.
