Summary
Description
Moving beyond a purely technical view of early warning, this session explains why effective systems must integrate risk knowledge, governance, communication, social behavior, and policy alignment. Using earthquakes as a detailed case study, the lecture illustrates how early warning works in practice—and why technology alone is never enough.
Key themes include:
* How risk is changing in the 21st century (climate change, pandemics, systemic risk)
* Why disasters are not “natural,” but socially constructed
* The four core elements of effective early warning systems
* Multi-hazard approaches and cascading risk
* Earthquake early warning: science, limits, and real-world applications
* Public and private sector uses (transportation, infrastructure, industry)
* Governance, policy integration, and cross-sector coordination
* Lessons from COVID-19, Tonga, Japan, Haiti, and the Caribbean
This lecture is part of a graduate-level course in Crisis and Disaster Management and is designed for students, practitioners, policymakers, emergency managers, and humanitarian professionals seeking to better understand how early warning systems reduce disaster risk—when they are people-centered and policy-enabled.
