Resonant Collapses
The Resonance of Tectonics, Desiccation, 
and Regulation in the Collapse of AO286
On the 19th of September 2017, an earthquake of magnitude 7.1 hit Mexico City, leading to the collapse of the seven storey building located on 286 Álvaro Obregón Avenue, or AO286, causing the death of 49 people.

Though Mexico City’s vulnerability to tectonic forces has been responded to by enacting progressively stricter building codes, 38 additional buildings collapsed that day, close to five thousand more structures were severely damaged, and 366 people were killed.[1]
Resonant Collapses is an investigative platform that articulates forces of tectonic plates, lake desiccation, and building code regulations to reveal seismic destruction not just as the result of earthquakes, but also as a complex event entangled with environmental violence and institutional negligence. The investigation exposes a form of seismic governance where the State mandates strict building regulations with one hand, while with the other progressively deteriorates the soil upon buildings are founded, all while failing to prosecute those who break the law.
Resonant Collapses presents spatial and cartographic timelines, regulatory databases and architectural representations at interscalar jumps across time, from five centuries of colonial control of water to the split-second of the collapse of AO286; and across space, from the planetary processes of tectonics to the constructive detail of a slab, to contribute to the public and political conversation which addresses the question: 

Why did AO286 collapse?
The 3 Forces & AO286 as a Seismograph
This platform conceptually and materially reconfigures AO286 into a seismograph to reveal how the building  was able to detect, register and present evidence of different forces which resonated upon it, thus leading to collapse.[2]  Just as a seismograph senses independent movements across directions X, Y, and Z, this platform reveals how AO286 recorded the forces of tectonics, desiccation, and regulation in its architecture. 

Explore the three different forces to examine how AO286 was able to detect, register and present evidence of violence. Each section first explains the force and how it approached the site of AO286, was registered by the building leading to the moment of its collapse.​​​​​​​ The investigation concludes by bringing the three forces together and how their resonance contributed to the building’s structural failure.
This first section surveys the planetary  force of tectonics and the registry of 58 years of earthquakes at the scale of AO286.
This second section inquires the force of desiccation at the regional scale of the Mexico City Basin and its registry as subsidence at the architectural scale of AO286.
This third section explores the force of regulation at the institutional scale of the Mexico City Building Code its registry as normative irregularities at the scale of architectural detail in AO286.
