• We had the opportunity to measure the microtremors of 46 buildings in Mexico City as members of the Technical Cooperation Mission that the Japan International Cooperation Agency (JICA) dispatched to work in Mexico from 19 October to 22 November 1985. Fourier analyses of the recorded microtremor data provided useful information about the dynamic properties of buildings damaged or undamaged by the 1985 Michoacan earthquake. The measured natural periods suggested that the rigidity of the undamaged buildings in Mexico City is only l/2 to l/3 that of Japanese buildings. Moreover, there was an apparent difference in the natural periods of the damaged and undamaged buildings.
