San Jose resident, Jose Cerna, and his wife and kids were with family in Mexico City yesterday. He was on the 3rd floor of a building and said it felt like it was moving side to side and up and down. His family was not injured.
"We just didn't know what to do. We just started running down the stairs, and fortunately the building stayed," he said.
Others are leaving SFO for Mexico City. Mexico City resident, Alice Davalos, was in the Bay Area for a week long vacation when she saw the news. Her family says it was chaotic in her hometown. Cars left on the streets and everyone trying to get to their kids at their schools.
Doctor Cesar Echegaray lives in the Bay Area and was planning on his trip to Mexico City to be a vacation. He doesn't know what to expect now.
"We've seen all the schools that have trouble and the hospitals, I'm a doctor, so maybe when I arrive home I'll get all my stuff and go help the people," Cesar Echegaray, M.D. said.
Mexico City's airport was facing delays and cancelations due to the earthquake.
