The Bay of Bengal and surrounding areas experience occasional seismic activity due to tectonic plate movements. While the area is not as prone to severe activity as the “Ring of Fire,” moderate earthquakes do occur. Other notable earthquakes in 2025 included a magnitude 5.1 quake in February and a magnitude 6.3/6.5 quake near the Andaman and Nicobar Islands in July, neither of which resulted in a tsunami.

The region is primarily remembered for the devastating magnitude 9.1-9.3 Sumatra-Andaman earthquake and tsunami of December 26, 2004, which killed over 227,000 people across 14 countries around the Indian Ocean. This event highlighted the importance of ongoing seismic monitoring and early warning systems. (ANI)
