A total of 61 people have been reported as the new death toll figure after an 8.2 quake hit Mexico's Pacific Thursday night.
"It's 71 (dead). Just for Oaxaca", said Jesus Gonzalez, a spokesperson for the state civil protection authority.
Federal Agrarian, Territorial and Urban Development Secretary Rosario Robles said in an interview with Milenio Television that on Saturday she had accompanied the Oaxaca Governor on a tour of several municipalities in the state.
Mexico President Enrique Peña Nieto announced Friday that the natural disaster killed 45 people in Oaxaca state, 12 in Chiapas and 4 in Tabasco.
The worst hit was the Zapotec indigenous city of Juchitán in Oaxaca. But they warned that those figures remain preliminary.
Rescue efforts following the quake, which struck the nation's Pacific Coast late on Thursday, were focussing on the worst-hit states of Tabasco, Oaxaca and Chiapas.
The powerful quake was felt as far away as the capital, Mexico City, sending residents out in the streets for fear of aftershocks.
