Population response to earthquakes and earthquake early warnings in Mexico

International Journal of Disaster Risk Reduction, 2021
Human responses to various natural hazards have been studied for more than a few decades. However, the effects of early warning interventions that alert the population to allow them time to take protective actions are not well known, at least to an extent where it could be compared within a socio-culturally similar region under two different scenarios:
