| Popis: | The time of occurrence of the large EQ that occurred recently in Mexico (March 20th, 2012, Mw = 7.4) is compared to the peak amplitude occurrence time of the local M1 and K1 tidal components. It is shown that the specific EQ occurred one (-1) day before the next following peak of the M1 tidal component, and was delayed for only +20 minutes after the corresponding K1 tidal peak. Therefore, the specific seismic event complies quite well with the earlier proposed physical mechanism (lithospheric oscillation) that causes triggering of large EQs. Key words: Mexico, large earthquakes, M1 tidal wave, K1 tidal wave, lithospheric oscillations, tidal oscillations, short-term earthquake prediction.
