“…Hence it was no surprise that EEW was very highly rated (4.6/5). New Zealand also received a high score (4.7/5) [22], and Switzerland ranked EEW slightly lower (4.2/5) [25]. In summary, surveys of prospective or nascent EEW systems achieved similar scores, but the two existing EEW systems showed a big difference.…”

“…In the event of experiencing any alert errors, participants acknowledge that EEW has limitations (M = 4.4, SD = 1.0). Additionally, post-alert messaging is essential to develop trust and awareness about the functioning of EEW [25,26], highlighted by the observation that participants want to know immediately the reason for receiving incorrect information (M = 4.0, SD = 1.2). Overall, results suggested that, despite alert limitations, EEW was perceived as valuable.…”

“…In this section, we compare the survey results from Central America to similar social science surveys for either prospective or existing public EEW systems, the section is structured similarly to section 3. The perceived usefulness, preferences of attributes and responses to EEW alerts in New Zealand [22] and Switzerland [25] were hypothetically assessed without having an EEW system in place. The performance of the existing EEW system in Mexico was assessed following the M7.1, Puebla earthquake in 2017 [14,15].…”

“…This requires identifying the needs and capacities of the target audience, determining drivers and restraints on how users can respond effectively to alerts and maximising public acceptance of the system [21]. In recent literature, social science surveys that document the behaviour, understanding and expectations of the public have been conducted in New Zealand [22][23][24], Switzerland [25], and the US [26]. In advance of the wide-scale roll-out of EEW in Central America, we aim to evaluate the level of desire for the system.…”

IntroductionAotearoa New Zealand (NZ) experiences frequent earthquakes, with a history of damaging and fatal events, but currently does not have a national, official earthquake early warning (EEW) system. Since April of 2021, Google's Android Earthquake Alert System has operated independently in NZ. While recent work has identified general public support for such a system, it is important to assess public knowledge of EEW as well as typical responses to receiving an alert. The protective actions “Drop, cover, and hold” are recommended and taught in NZ and previous research found strong intentions to undertake these and other protective actions in response to an alert.MethodHowever, it is important to explore a range of responses to these novel EEWs, including how much people know about them, what actions they took in response to the warning, and their overall judgment of the system including its usefulness. We undertook surveys following two widely received alerts from the Android Earthquake Alert System to assess public knowledge, perceptions, and responses to these alerts with a total sample size of 3,150.ResultsWhile most participants who received the alert found it useful, knowledge of both EEW generally and the Android System specifically was low and few participants used the time to protect themselves from shaking.DiscussionThese findings reiterate the importance of education and communication around a warning system, so that the public know how to act when they receive an alert.

Designing understandable, action-oriented, and well-perceived earthquake risk maps—The Swiss case study

With seismic risk assessments becoming more available and reliable over the last years, the need to communicate seismic risk emerged. Seismic risk allows people to understand what impacts earthquakes can have and how they could affect their lives. In Switzerland, a nation-wide seismic risk model (ERM-CH23) was published in 2023 demanding sophisticated communication products to inform about its results. Since only limited research has been conducted on how to best communicate earthquake risk information to societies including the general public, key elements of the outreach activities were tested before the model release. To this end, we, an interdisciplinary group, conducted a nationwide survey in Switzerland in December 2022 to test different earthquake risk map designs by varying the color scale and the legend type. We analyzed the effects of the map and legend design on people's correct interpretation of the risk information, perceived usefulness, risk perception, and motivation to take action. Our survey revealed that (i) a legend with the combination of qualitative and quantitative labels leads to more accurate interpretations of the information presented on the map and is preferred by the public; (ii) the color scale determines how people perceive the spatial risk; and (iii) personal factors influence people's interpretation skills, risk perception, and intention to take action. Our study thus provides insights and recommendations on how to best design user-centered earthquake risk maps as a key outreach product to ensure their effective use by the public, consequently enhancing society's resilience to earthquakes in the long term.
