Left y-axis (black solid line) indicates the location's daily log frequency, right y-axis (red dotted line) indicates the location's weekly probability of receiving a descriptor phrase like "Puerto Rico". Hurricane Maria in 2017, the location "San Juan" was less likely to receive a descriptor (e.g., "San Juan, PR") following the peak in collective attention volume. While this shift appears to be due to time<cite> (Staliūnaitė et al. 2018)</cite> , the shift in descriptor use may also stem from non-temporal factors as well, such as an author's expectations of their audience (audience design) and additional information such as links to external news articles, included in the same sentence with the location (a micro-level aspect of the discussion).
