地震警报系统（SAS）是由市政府赞助开发的一项公共服务，旨在减轻地震灾害。自1991年8月以来，经过84个月的连续运行，SAS已经能够在格雷罗海岸探测到681次地震事件；其中12次强烈到触发墨西哥城的一般警报，33次受到限制，还有一次虚假的一般警报。强烈或限制预警范围对应于预测的地震震级大于6级或大于5级。在1995年9月14日“Copala”7.3级地震期间，SAS被激活，并在“S”型地面运动到达前72秒在墨西哥城发布了一般预警信号。这次地震警报覆盖了大约400多万居民。由于实施了减少地震危害的计划，学校里的孩子们反应热烈。科帕拉地震帮助我们确定了社会对地震早期预警信号反应的优势和劣势。国家公共教育部公共教育秘书处的减灾长期计划在各级学校的儿童中建立了地震意识。尽管孩子们没有遭受1985年地震的灾难性后果，但他们今天比经历过那场灾难性事件但仍未受过培训的普通人更有意识。
The Seismic Alert System (SAS) is a public service developed with the sponsorship of the City Government Authorities, with the aim to mitigate seismic disasters. Since August, 1991, after 84 months of continuous operation, the SAS has been able to detect 681 seismic events in the Guerrero Coast; 12 of them so strong as to trigger general alerts in Mexico City, 33 restricted, and one false general alert. The warning ranges strong or restricted correspond to seismic magnitude forecasted great than 6, or great than 5. During the “Copala” M7.3 earthquake, on September 14, 1995 the SAS was activated and issued a general warning signal in Mexico City, 72 seconds prior to the first arrival of “S” ground motion. This earthquake warning reached an estimated population of more than 4 million citizens. The response of children in schools was massive due to the application of an earthquake hazard reduction program. The Copala earthquake helped us to identify strengths and weaknesses of societal response to the earthquake early warning signal. The long-term plan of hazard mitigation of the National Ministry of Public Education, Secretaria de Educacion Publica (SEP), has created an earthquake awareness in the children of various school levels. Even though the children did not suffered the disastrous consequences of the 1985 earthquake, they are today more aware than the average person who lived through that disastrous event and who is still not trained.
