After the coup of 1973 and the establishment of the military regime, major changes in urban planning did not take place until the 1980s, when the government adopted a neoliberal economic model. In 1979, the master plan was amended. The urban area was extended to more than 62 000 ha for real estate development. This created urban sprawl, especially in La Florida, with the city reaching 40 619 ha in size in the early 1990s. The 1992 census showed that Santiago had become the country's most populous municipality with 328,881 inhabitants. Meanwhile, a strong earthquake struck the city on 3 March 1985. Although it caused few casualties, it left many people homeless and destroyed many old buildings.
