Despite their remoteness from each other, Japan and Mexico share a critical characteristic: the seismic hazard. In the past, both nations have been hit by great earthquakes that have caused serious human and material losses. Although the prediction of earthquakes is not yet possible, the development of early warning systems and their constant innovation is a priority, especially the studies of the horizontal-to-vertical spectral relationship of microseisms, which can help the study and understanding of earthquakes’ nature, as well as their impact on infrastructure. It is for mutual benefit to Japan and Mexico that cooperation between university institutions specialized in seismological studies increases to jointly create study and innovation mechanisms.
