From Damage Maps to News Agendas: Agenda-Setting and the Visibility Deficit of Cultural Heritage After the 2023 Hatay Earthquakes

After major disasters, news media selectively construct the public record of what has been lost. This study examines that pattern by comparing an independently derived satellite-based inventory of damaged cultural heritage in Hatay, Türkiye, with a corpus of 79 Turkish-language online news reports published between February 2023 and February 2024. Under the primary retrieval protocol, only 16 of the 86 ARIA-export assets appeared directly in the coverage; with six further off-export or proximity-based cases, 22 reported assets entered the news in total. A targeted asset-name search then located 15 further reports, containing 17 additional direct references to damaged assets. Even on the most inclusive reading, in which every one of these references is treated as a previously uncounted and non-overlapping asset, at least 53 of the 86 assets (61.6%) remained outside the news record. The analysis also covers attribute salience, temporal patterns, and outlet concentration in the coverage. Drawing on first- and second-level agenda-setting theory, and treating gatekeeping and media-system conditions as contextual mechanisms, it defines visibility deficit as the measurable gap between independently documented damage and the damage that enters a defined news corpus. This gap need not imply deliberate suppression. It may follow from editorial priorities, limited access to sites, the availability of visual material, or the limited capacity of newsrooms to work with geospatial data. By attending to what stays outside the news agenda rather than only to differences in salience among covered items, the study identifies a structural boundary of agenda setting and extends agenda-setting research into measurable non-coverage after disaster.
