Remembering some of the notable damaging earthquakes and tsunamis over the past quarter century

666

Published on

Each disaster is an opportunity to add to the “global book of knowledge” on occurrences, consequences, and disaster risk reduction measures. 2014--2020 is a good time for a global surge in educational, technical, health care, and political capacity building in all five pillars of community disaster resilience. All past disasters demonstrate the urgency of becoming disaster resilient. Premise: a disaster on the same scale should never happen twice in a community.
