The coastline between Reynisfjall mountain and Kúðafljót river in south Iceland has undergone large changes since the beginning of the 20th century. With new data on coastline position, the changes in coastline position and volume between 1904 and 2024 were calculated, including a new calculation of the volume of Kötlutangi protrusion soon after the 1918 glacial outburst flood caused by an eruption in Katla volcano. The new volume is about 325 Mm3 of material deposited below the 0 meters in chart datum, increasing the total volume by about 25-75 Mm3 from previous calculations.
