Exploring Evidence-based Guidelines for Protective Actions and Earthquake Early Warning Systems
Earthquake early warning systems (EEW) are becoming increasingly available or in development throughout the world. With public alerting in Mexico, Japan, Taiwan, New Zealand, Philippines and the United States, among others, it is important to provide evidence-based recommendations for protective action so people can protect themselves when they receive an alert. Best-practice warning communication research suggests that providing a protective action will increase the efficacy of the message. However, given the diversity of earthquakes and building types, and social/cultural contexts that these systems exist in, the question is: what is the best protective action to recommend? In this research, we seek to answer this question by developing guidelines for consideration when deciding on what advice is best to provide.
We outline key lessons and influential theories from the social sciences and humanities that can be integrated into messaging for EEW systems. We then provide an overview of what is known about injuries and fatalities during earthquakes and review current protective action recommendations and associated public education campaigns. We explore three critical questions for operators of these systems regarding what protective action to recommend, thereby developing a guideline to assist decision makers of these systems. We explore our limitations and future directions for the research, including more data types that earthquake injury researchers can collect to help fill gaps in the literature.
We determined factors to consider include: 1) social, cultural and environmental context such as who people are with and their social roles and what type of building an individual is located in when an earthquake happens, 2) demographic variables such as gender, age and previous history with earthquakes and 3) magnitude and intensity that influence the duration and impacts of the earthquake itself.
