Early today, June 25, 2025, the Andaman Sea experienced seismic activity with an earthquake measuring 4.2 on the Richter scale. According to the National Centre for Seismology (NCS), the earthquake struck at a shallow depth of 20 kilometers.

While the magnitude of 4.2 is considered relatively moderate, earthquakes in this region are not uncommon. The Andaman and Nicobar Islands are located in a seismically active zone, making them prone to frequent tremors. Earlier this week, on June 24, 2025, the Andaman Sea experienced two more earthquakes. One was a magnitude 5.2 earthquake at approximately 3:47 PM IST and a depth of 61 kilometers. The quake epicentre was located at a latitude of 8.97° North and 94.24° East longitude. Another one was a lighter earthquake with a magnitude of 3.6 that occurred 320 km southeast of Port Blair.

The NCS and other seismological agencies continuously monitor seismic activity in the region to assess potential risks and provide timely information to the public. Following the 5.2 magnitude earthquake, authorities did not issue a tsunami warning, and there were no immediate reports of casualties or significant damage.

The Andaman Sea region has a history of experiencing earthquakes of varying magnitudes. According to seismic data, the area near the epicenter of the recent quake experiences an average of 30.4 earthquakes per year. Historical data indicates that larger earthquakes, exceeding magnitude 6, occur less frequently, approximately every 5 to 10 years.

Due to the frequency of earthquakes in the Andaman and Nicobar Islands, preparedness and awareness are crucial for the local population. Residents are advised to stay informed about safety measures and emergency procedures to minimize the impact of potential seismic events. These include securing homes, knowing evacuation routes, and having emergency kits ready. Continued monitoring and research in the region are essential to better understand the seismic activity and improve earthquake early warning systems.
