What the record says

NCEI’s account, from the sources it cites.

Three people killed in Oaxaca and two at Mexico City. Four people injured at Juchitan and three at Tlacotepec. Some houses and a bridge collapsed in the Tehuanepec area. Juchitan, Oaxaca, Mexico - CDI: 7; Copoya, Chiapas, Mexico - CDI: 6; Asuncion Ixtaltepec, Oaxaca, Mexico - CDI: 5; Loma Bonita, Oaxaca, Mexico - CDI: 5; Oaxaca, Oaxaca, Mexico - CDI: 4 (reference #13456)

Mexico's seismological authorities said the Saturday tremor was an aftershock of the September 7 earthquake. The aftershock was not as destructive as the previous tremors; however, fear is running high among Mexicans. Terrified residents ran into the streets, where they crouched and prayed as earthquake sirens went off. Two women died of heart attacks as the ground shook, the city government said. Three other deaths were also linked by officials to the earthquake, including a man who was attacked by a swarm of wild bees. (reference #11897)

The Ixtlaltepec bridge and at least 8 houses in Juchitan that had been affected by the earthquake of September 7, collapsed with the earthquake today. In Union Hidalgo, three more houses collapsed. Through a statement, Civil Protection of Oaxaca reported that two people in Juchitan were injured by the earthquake. (reference #11898)
