This is a database of more than 11,000 extreme social-ecological events for colonial Mexico spread across about 660 unique geographic sites, including approximate locations of some 'unspecified sites' where the geographic center of the state or region was used. Mostly, geographic locations are specified and precisely located. The 11,000+ events are given a descriptive name by each editor and are then classified into thirteen event-types: abundance, church response, cold, crisis, dry, epizootic, geophysical, hot, illness, scarcity, state response, storm, and wet.
