On August 8, 1993 at 6:35 p.m., Guam was struck by a magnitude 8.1 earthquake. The earthquake caused the partial collapse of the Royal Palm Resort, a new 220-unit, 12-story hotel and condominium complex that opened for occupancy just 18 days before the earthquake. The resort incorporated two nearly identical buildings, the "Beachside Tower" and the "Roadside Tower," which were constructed of reinforced concrete, with special moment-resisting frames providing the lateral force resistance. The Beachside Tower suffered partial collapse but the damage to the Roadside Tower consisted only of cracking of the architectural masonry walls. Exponent's structural engineers performed an investigation to assess the damage in relation to the construction of the building. To visualize the earthquake response and progressive collapse of the Beachside Tower, the Visual Communication group prepared a real-time 3D animation.
