The 2004 Indian Ocean tsunami remains one of the deadliest natural disasters in history, claiming over 230,000 lives and displacing millions.

Triggered by a massive undersea earthquake near Sumatra, the waves devastated coastal regions across Southeast Asia, including Thailand, Indonesia, and Sri Lanka.

Swedish dentist Anna Jinghede Sundwall recalls the harrowing task of identifying victims through dental records in Thailand, while Lisa Borg, then 15, saved her younger sister from the deadly waves on Koh Lanta.

Survivors recount the chaos, trauma, and resilience in the face of unimaginable loss.

Over 500 Swedes perished, and many survivors still grapple with the emotional scars two decades later.
