Public perceptions and information seeking intentions related to seismicity in five Texas communities

Abstract

Texas has experienced levels of seismicity comparable to areas of California in recent years, and seismologists suggest that the increased activity in Texas is likely the result of human activities associated with oil and gas extraction. However, the general public is largely unaware of induced seismicity and related risks. To better understand this lack of awareness and how it might be addressed, we sought guidance from Kahlor's (2010) planned risk information seeking model to explore the social-psychological factors that are likely to influence Texan's intentions to seek information about the potential risks posed by earthquakes. We test the model using data collected from residents in five Texas communities that have varied experiences with seismicity. The data supports the model: the variance in intentions to seek information about earthquake risks were largely explained by positive attitudes towards seeking such information, perceived control over the ability to seek such information, perceived social pressure related to seeking such information, perceived earthquake risks, risk-related emotion (e.g., worry) and a perceived need for more information about earthquake risks. The study highlights the applicability of this risk information-seeking model to the context of seismic risk, and suggests ways in which scientists and communicators might engage the public more effectively with the topic.
