Ani Naqvi remembers the Boxing Day tsunami 20 years ago not just as the day when she nearly lost her life but one that gave her new purpose. She had just turned 33 and was visiting a friend in the Sri Lankan surfing village of Arugam Bay on 26 December 2004 when one of the largest earthquakes ever recorded struck off the coast of Indonesia,

In Thailand, people gathered at a memorial ceremony in Ban Nam Khem, a small fishing village in Phang Nga province that bore the brunt of the devastating wave in the country. The tsunami claimed the lives of over 8,000 people in Thailand. Many remain missing and nearly 400 bodies are unclaimed to this day.

On Boxing Day 2004, an earthquake in the Indian Ocean near Indonesia set off a tsunami which killed almost 250,000 people. It was the deadliest natural disaster this century, and was probably the deadliest tsunami in human history.
