The A23a iceberg, which has lost its status as the world’s largest iceberg due to its gradually shrinking area, may break apart within days or weeks.

Axar.az reports that this was announced by the US National Aeronautics and Space Administration (NASA).

In December 2025, scientists from the Arctic and Antarctic Research Institute (AARI) revealed that A23a, which they had been monitoring for nearly 40 years, had lost 67% of its original area.

The agency added that the iceberg is currently moving in the South Atlantic Ocean, southeast of South America.

The A23a iceberg calved from the Filchner Ice Shelf in 1986. At the time of its formation, it covered an area of 4,170 square kilometers. For more than 30 years, it remained grounded in the central Weddell Sea. In mid-November 2023, it “awoke” and began moving again. In the spring of 2024, it unexpectedly started drifting toward the Scotia Sea along the coast of the Antarctic Peninsula.
