MEXICO CITY – Mexico escaped major destruction from a magnitude 7.2 earthquake that jolted southern and central parts of the country, authorities said Saturday, though 13 people were killed in the crash of a helicopter sent to assess the damage. A national emergency committee that convened after Friday’s quake adjourned in the afternoon after reporting 200 homes had been damaged, primarily in the southern state of Oaxaca, along with the city hall and main church in the town of Santiago Jamiltepec. Two people sustained broken bones but had been treated in Pinotepa Nacional, Oaxaca, and their lives were not in danger, the Interior Department said in a statement. Nearly 1 million customers were said to have lost power, but service had been restored to 99 percent of them, it added. While there were no deaths directly linked to the quake, 13 people were killed and 16 injured when a military helicopter carrying officials assessing damage from the temblor crashed late Friday. The Oaxaca state prosecutor’s office said in a statement that five women, four men and three children died at the crash site and another person died later at the hospital.
