Post facto analysis of Zumpango del Río earthquake of 11 December 2011 (Mw 6.5) (centroid moment tensor catalog), comparing an earthquake early warning system using the tP+3 algorithm with the 2(tS−tP) and (tS−tP) algorithms. The horizontal axis corresponds to GMT beginning at the origin time of the earthquake. The red dot on the map shows the location of the Zumpango earthquake.

AmaxHF versus Amax at CU for earthquakes listed in Table 1. For clarity, only some of the events are identified. Note that the 7 earthquakes with the largest AmaxHF values during the period 1964–2011 are all intraslab earthquakes. AmaxHF of Michoacan and Zumpango earthquakes are 5.4 and 17.0 gal, respectively. None of these events caused damage in the hill zone.

Post facto analysis of the 11 December 2011 Mw 6.5 Zumpango earthquake with a focal depth of 65 km. The (tS−tP) and the 2(tS−tP) algorithm would have issued an alert in Mexico City ∼27 and 16 s before the arrival of the S waves.

Same as Figure 4 but for the lake-bed zone site SCT. In this case, the AmaxHF values as well as Fourier spectra at high frequencies of the two earthquakes are similar.
