This part of the Global Disaster Laboratories series delves into valuable lessons from past earthquake disasters worldwide, emphasizing the need for nations to adopt and implement policies to enhance their disaster resilience. From the detrimental impacts of earthquakes on different regions to specific examples of lack of preparedness leading to significant loss of life and property, this study underscores the importance of learning from global seismic events. Through detailed analysis of earthquake-prone regions and case studies, the imperative role of timely responses and proactive measures is highlighted for preventing future catastrophes. Join us in understanding the critical steps towards building a more resilient world against earthquake disasters.

LEARNING FROM GLOBAL DISASTER LABORATORIESPART 2: EARTHQUAKES Walter Hays, Global Alliance for Disaster Reduction, Vienna, Virginia, USA
WE CONTINUE TO OPERATE WITH A FLAWED PREMISE: KNOWLEDGE FROM EARTHQUAKE DISASTERS, WHICH OCCUR ANNUALLY ON A GLOBAL SCALE, IS ENOUGH TO MAKE ANY NATION SUSCEPTIBLE TO EARTHQUAKES ADOPT AND IMPLEMENT POLICIES THAT WILL FACILITATE ITS OWN DISASTER RESILIENCE
FACT: IT USUALLY TAKES MULTIPLE EARTHQUAKE DISASTERS BEFORE A STRICKEN NATION WILL ADOPT AND IMPLEMENT POLICIES THAT MOVE IT TOWARDS EARTHQUAKE DISASTER RESILIENCE
FACT: MOST UNAFFECTED NATIONS DON’T EVEN TRY TO LEARN ANYTHING NEW FROM ANOTHER NATION’S EARTHQUAKE DISASTERS AND CERTAINLY DON’T CONSIDER THEM TO BE A BASIS FOR CHANGING EXISTING POLICIES

LESSON: THE KNOWLEDGE AND TIMING OF ANTICIPATORY ACTIONS IS VITAL • The people who know: 1) what to expect (e.g., strong ground motion, oil effects, tsunami wave run up, ground failure),2) where and when they will happen, and 3) what they should (and should not) do to prepare for them will survive.
LESSON: TIMELY, REALISTIC DISASTER SCENARIOS SAVE LIVES • The people who have timely, realistic, advance information that facilitates reduction of vulnerabilities, and hence the risks associated with strong ground shaking, tsunami wave run up, and ground failure will survive.
LESSON: EMERGENCY RESPONSE SAVES LIVES • The “Uncontrollable and Unthinkable” events will always hinder the timing of emergency response operations, especially the search and rescue operations that are limited to “the golden 48 hours.”
LESSON: EMERGENCY MEDICAL PREPAREDNESS SAVES LIVES • The local community’s capacity for emergency health care (i,e., coping with damaged hospitals and medical facilities, lack of clean drinking water, food, and medicine, and high levels of morbidity and mortality) is vital for survival.
LESSON: EARTHQUAKE ENGINEERED BUILDINGS SAVE LIVES • Buildings engineered to withstand the risks from an earthquake’s strong ground shaking and ground failure that cause damage, collapse, and loss of function, is vital for protecting occupants and users from death and injury.
LESSON: THE INTERNATIONAL COMMUNITY ALWAYS PROVIDES AID • The International Community provides millions to billions of dollars in relief to help “pick up the pieces, ” but this strategy is not enough by itself to ensure earthquake disaster resilience.
