Giant iceberg capsizes off Ilulissat, Greenland

A livestream camera positioned at the entrance of the UNESCO‑listed Ilulissat Icefjord captured a massive iceberg slowly tipping over and rolling onto its blue underside. The event, recorded on 25 July, lasted about 55 minutes and produced waves that reached the nearby town but caused no injuries or damage.

Scientists explained that roughly 90 % of an iceberg’s volume lies below the waterline; uneven melting or fragment loss can shift its centre of gravity, causing it to roll until a new equilibrium is found. The exposed underside displayed a deep blue colour, a contrast to the white, snow‑covered top that is normally visible.

The rollover is a natural occurrence in the Ilulissat region, which is fed by the fast‑moving Sermeq Kujalleq glacier, one of the world’s most active ice streams. While the spectacle is striking, it also highlights the broader climate context, as Greenland’s ice sheet is melting at an accelerating rate and contributing to global sea‑level rise.
