​Disaster literature agrees that knowledge alone is insufficient to promote the adoption of preparedness by populations. Nevertheless, this is a prerequisite for initiating behaviour. Governments and Civil Protection authorities are among the multiple sources of information on preparedness and appropriate disaster behaviours. If these sources are trusted, members of the public will accept the information they transmit. However, few studies have addressed the content of risk communication messages from European authorities. We analysed and discussed the frequency and diversity of household earthquake preparedness and response measures recommended by European Civil Protection authorities in countries exposed to seismic risk, using 84 official website documents and texts from 25 countries. Authorities highly recommended behaviours to apply during an earthquake, focusing on physical protection and conforming to the literature. However, official recommendations weakly recommended planning measures, a well-established preparedness component in the literature. Furthermore, authorities failed to reinforce skill acquisition, insurance acquisition, structural mitigation, and other mitigation measures. Nevertheless, non-structural mitigation was highly advised and was more frequent than stockpiling recommendations. The results also pointed to concerns about the behaviour of residents during and after an earthquake, misinformation, and to the diversity of measures in each country, disagreeing with previous research. Local differences and factors related to the process of selecting recommendations may explain the results. This study contributes to the literature on earthquake recommendations, risk communication, household preparedness and response, and practical applications of preparedness and response literature.​
