Mexico City was severely affected by the September 19, 2017 Puebla-Morelos earthquake (M_w = 7.1). City authorities confirmed that more than 12,000 structures for all uses were damaged as a consequence of this earthquake. In this paper, the focus of attention is devoted to trying to quantify in a simple manner how resilient the built environment in Mexico City was during the September 19, 2017 earthquake. Global statistics compiled for the severity of damage observed during this seismic event from detailed information gathered from well-documented and detailed damage surveys were used for this purpose. Also, an update is provided on how the seismic reconstruction and recovery processes of the built environment in Mexico City have been after this earthquake. This adaptive resilience has been assessed from reliable information and statistics of the ongoing reconstruction process of the affected built environment in Mexico City. The implementation of structural health monitoring programs for typical, representative buildings within the city would be germane to detect and correct potential structural deficiencies on time before the next strong earthquake may strike, then helping to improve the seismic resilience of the built environment.

墨西哥城受到 2017 年 9 月 19 日普埃布拉-莫雷洛斯地震的严重影响（M _w = 7.1)。市政当局证实，这次地震破坏了超过 12,000 座各种用途的建筑物。在本文中，关注的焦点致力于尝试以简单的方式量化墨西哥城建筑环境在 2017 年 9 月 19 日地震期间的弹性。为此目的，使用了从有据可查和详细的损坏调查中收集的详细信息，针对此次地震事件期间观察到的损坏严重程度编制的全球统计数据。此外，还提供了有关地震后墨西哥城建筑环境的地震重建和恢复过程的最新情况。这种适应性复原力是根据墨西哥城受影响建筑环境正在进行的重建过程的可靠信息和统计数据进行评估的。
