Prediction of peak, horizontal ground motion parameters in mexico city from coastal earthquakes

While the need for prediction of peak ground motion in Mexico City from coastal earthquakes is evident, the peculiar site conditions in the city and the paucity of strong motion data in the past have given rise to doubtful attenuation relations. We now have strong motion recordings of 16 coastal ear...

Descrição
Resumo:While the need for prediction of peak ground motion in Mexico City from coastal earthquakes is evident, the peculiar site conditions in the city and the paucity of strong motion data in the past have given rise to doubtful attenuation relations. We now have strong motion recordings of 16 coastal earthquakes (5.6~Ms~8.1) at a hill zone site in Ciudad Universitaria (CUIP) (282~R~466 km) including those from the 19 Sep 1985 (Ms= 8.1). Michoadn earthquake. two of its aftershocks, and 8 other events which were not analyzed previously. From 16 peak horizontal acceleration (amax>) and 14 peak horizontal velocity values (vmax) we propose the following attenuation relations for CUIP
