Abstract. Erosional coastal sections of the coastal plains of Eastern Chukotka have been studied by the authors since 2012. Since then, a significant amount of field data has been accumulated on key segments of the coast. In the 2023 field season, aerial photography of several sections of the coast was carried out, accompanied by the arrangement of a geodetic network with height reference. The obtained field materials made it possible to construct a high-precision digital terrain model for the main key site in the village of Lorino, represented by the remnant of a marine terrace composed of heterogeneous sands, sandy loams and peat. The obtained materials will make it possible to study the dynamics of the retreat of the key area not only in plan, but also to estimate the volumetric rates of erosion of non-lithified sediments. As a result of field research, aerial photography of coastal thermal cirques was also carried out in order to determine the dynamics of their development. Keywords: Chukotka, permafrost, coastal erosion, thermicirque, retreat coasts
