satellite imagery shows the before and after the calving in 2023. In 2012, previously stable large chasms in the ice shelf (cracks which clearly go all the way through to the sea) started expanding, which was expected to cause large parts of the Brunt Ice Shelf to break off within the next few years. On 26 February 2021, the
Iceberg A-74 duly broke away from the north-facing shelf, separating from the edge of the shelf at the
McDonald Ice Rumples along the North Rift and finally joining the Brunt-Stancomb chasm. As of 28 February, A-74 was located at 75° 13' South, 25° 41' West and measures on its longest axis and on its widest axis. On 23 January 2023, the second major calving from this area occurred when the crack known as Chasm-1 fully extended through the ice shelf, creating a iceberg. Chasm-1 had continued to grow since 2015 and by December 2022 extended across the entire ice shelf, marking the beginning of the calving event. ==See also==
