The earthquake that on Tuesday killed at least 155 people in Mexico City and toppled dozens of buildings there was all the more destructive because of the city’s unusual position atop an ancient lake bed.
The animation above, based on a model by Víctor Cruz-Atienza, a professor of geophysics at the National University of Mexico, shows how the shock waves of a hypothetical earthquake near Mexico City would spread. Darker red areas indicate the strongest ground movement.
