Petanahan sub-district has three villages directly adjacent to the sea: Karangrejo Village, Karanggadung Village, and Tegalretno Village. This study aims to analyze the level of tsunami susceptibility in the coastal area of Petanahan District in the Kebumen Regency. Analysis of the level of tsunami susceptibility using assessment methods, weighting, and map overlays using tsunami hazard parameters, including elevation, slope, land use, distance from the shoreline, and distance from rivers. Then the Weighting of the Tsunami Vulnerability Level uses the formula N = Bi X Si, where Bi is the weight on each criterion, and Si is a score on each criterion. The weighting results are then divided into five classes, very low, low, medium, high, and very high. The results of this study indicate that the tsunami hazard in a coastal area of Petanahan Regency consists of a very high class (93.904 ha/8.33%), a high class (567.804/50.35%), and a medium class of (465.962 ha/41.32%). The results of this research on the vulnerability to tsunamis can be used by the community, especially in the research area, to increase preparedness in dealing with tsunami disasters. At the same time, the Government can take policies in carrying out disaster risk reduction activities of a tsunami, especially in the research area.

<p><em>Tingginya tingkat kerawanan bencana mendorong perlunya membentuk masyarakat yang resilien. Resiliensi masyarakat memberikan kesiapsiagaan bagi masyarakat, menentukan bagaimana cara merespon, dan bagaimana melakukan recovery dalam menghadapi bencana tsunami. Berdasarkan hal tersebut penelitian ini bertujuan untuk mengetahui tingkat resiliensi masyarakat terhadap bencana tsunami di pesisir Kecamatan Petanahan, Kabupaten Kebumen tahun 2020. Penelitian ini menggunakan metode deskriptif kualitatif. Tingkat resiliensi masyarakat terhadap bencana tsunami di pesisir Kecamatan Petanahan tahun 2020 berada pada tingkat resiliensi tinggi (high resilience) dengan tiga indikator tertinggi adalah coastal resource management dengan nilai 99,75%, risk knowledge dengan nilai 83,74% dan warning &amp; evacuation dengan nilai 90,91 %. Selain itu, elemen resiliensi yang tergolong sedang (intermediate resilience) yaitu society &amp; economy dengan nilai 52,31%, land use &amp; structural design dengan nilai 55,38 %, dan disaster recovery dengan nilai 41,15%, dan elemen resiliensi rendah (low resilience) yaitu governance dengan nilai 33,85% dan emergency response dengan nilai 20%.</em><em></em></p>
