AB: Central Mexico is not only of scientific interest but also of great economic and social impact since it is the most populated region of the country of Mexico. Of particular importance to the seismic hazard in this region are intermediate-depth earthquakes, not only because of some highly energetic events, but also because of the proximity to the cities and villages in the Mexican Altiplano. This work is an effort to characterize the seismic-wave propagation parameters, regional attenuation and magnitude estimation in this region. I discuss the major issues regarding ground motion scaling of this challenging region of the world such as the predictive relation within and around the Trans Mexican Volcanic Belt, local magnitude estimations and source excitation characteristics.
