ResumoAbstract A very large coseismic displacement (≈304 cm) was recorded at the city of Concepción during the moment magnitude (Mw) 8·8 Offshore Maule, Chile earthquake of 27 February 2010. The Alto Rio building, a 15‐storey reinforced concrete structure with two underground levels, experienced a global overturning collapse, resulting in the death of eight of its occupants. Ever since, a lingering question has preoccupied the minds of structural engineers and earth scientists: Did the large coseismic displacement cause the overturning collapse of this building? The answer based on the analyses provided in this paper is no. Copyright © 2010 John Wiley & Sons, Ltd.
