On December 26, 2024, thousands gathered across Southeast Asia and South Asia to commemorate the 20th anniversary of the devastating Indian Ocean tsunami, one of the deadliest natural disasters in history. The tsunami, triggered by a 9.1 magnitude earthquake off the coast of Sumatra, Indonesia, struck 14 countries, killing around 230,000 people. In Indonesia, memorial services took place in Aceh province, the hardest-hit area, where mass graves and the Grand Baiturrahman Mosque were the focal points of remembrance. In Sri Lanka, survivors and officials observed a moment of silence at the Peraliya Tsunami Memorial, while in Thailand, ceremonies were held at the Phang Nga Tsunami Memorial and Tsunami Wall. Similarly, in India’s Tamil Nadu, candles were lit and prayers offered for the victims.
These memorials not only honored the victims but also highlighted the global improvements in disaster preparedness since the tragedy. The tsunami prompted significant changes in early warning systems across the Indian Ocean region. Nations such as Indonesia, Sri Lanka, and India have invested in advanced seismic monitoring technologies and tsunami detection systems, which now offer a crucial buffer against future tsunamis. Additionally, communities have been educated on evacuation plans, and coastal infrastructure has been strengthened. The disaster also led to the establishment of the Indian Ocean Tsunami Warning System in 2006, which serves as a model for international cooperation in disaster risk reduction. Despite these advancements, the anniversary serves as a reminder of the ongoing need for vigilance and preparedness in the face of natural hazards. More
