On Tuesday 19 September, the 32nd anniversary of the magnitude 8 earthquake that levelled large parts of Mexico City in 1985, an earthquake of magnitude 7.1 hit the city and neighbouring states. In 1985 the epicentre was off the Pacific coast, and the death toll reached at least 10,000. When that one set our house rocking back and forth at 7.17 a.m., my wife Betty and I were about to send our daughters to school. They boarded the bus and we turned on the television. For the next three days we witnessed the havoc at collapsed hospitals, hotels, and residential and office buildings. This time I was crossing Chapultepec Park, on my way to pick Betty up from the ABC Hospital. At 1.14 p.m., two hours after a planned earthquake drill and 12 days after a quake in Chiapas and Oaxaca killed at least 98 people, my taxi suddenly halted and began moving to and fro on the undulating road, while trees swayed towards and away from me. At the hospital, staff and patients were hugging the walls.
