#EQHistory: Today marks the 40th anniversary of the 1985 M8.0 Michoacan, Mexico, earthquake. Causing widespread damage and loss of 9500+ lives, many in the greater Mexico City area, this event was the impetus for creating Mexico's Earthquake Early Warning system, the first world's public EEW system.
