What is The collapse of Álvaro Obregón 286 building in Mexico City during the September 19, 2017 earthquake. A case study about?

During the September 19, 2017 Puebla-Morelos Earthquake in Mexico City, 46 buildings experienced global or partial collapses. However, perhaps the most emblematic collapsed building during this earthquake was Álvaro Obregón 286 building (AO-286), located at Hipódromo Condesa District in the soft soils of former western Lake Texcoco. Unfortunately, 49 people died there, being the building which claimed more victims in Mexico City during this earthquake. Taking aside this tragedy, the collapse of Alvaro Obregón 286 building is an interesting case study from a structural engineering viewpoint, as it has several angles to explore to try to explain the reasons of its failure. In this paper, the authors report a detailed study that they conducted to try to understand better the collapse of AO-286 building and the observed damage in the neighboring AO-284 building. As no blueprints or lab data were publicly available, the authors did first a forensic study. Information was gathered from sources like press reports, public information and pictures taken at the site by the authors and by many other people. Then, using Google Maps and Google Earth information and tools, the following items we
