A 4.2 magnitude earthquake struck the Bay of Bengal on Tuesday, December 2, 2025, at 7:26 AM IST. The quake originated at a depth of 35 km, with coordinates 20.56°N latitude and 92.31°E longitude, confirmed by the National Centre for Seismology (NCS).
There have been no reports of damage or casualties. Authorities continue to monitor seismic activity to ensure public safety and readiness for any aftershocks.
Seismic Background of the Bay of Bengal
The Bay of Bengal is subject to tectonic activity due to movements of the Indian and Burmese plates beneath the ocean floor. While the area experiences periodic moderate earthquakes, it is relatively less active compared to highly seismic zones like the “Ring of Fire.”
The 4.2 magnitude tremor is moderate and typical of the region, which has witnessed larger quakes such as the devastating 2004 Sumatra-Andaman earthquake that triggered a catastrophic tsunami. Monitoring such events is crucial for coastal communities vulnerable to seismic hazards.
Event Specifics and Official Details
According to NCS data, the earthquake depth at 35 km helps to mitigate severe surface shaking. The NCS communicated through posts on social media platforms like X (formerly Twitter) to update the public promptly.
This event is part of ongoing seismic monitoring efforts, which included earlier quakes in 2025 with magnitudes of 5.1 near the Andaman and Nicobar Islands and 4.2 in Tajikistan that did not cause damage or tsunamis.
NCS emphasises transparent communication to reduce panic and raise public awareness about earthquake preparedness.
The Logical Indian’s Perspective
Natural events like this earthquake highlight the ever-present forces shaping our planet and the importance of scientific vigilance and disaster readiness.
Though relatively mild, it reminds communities to maintain preparedness and authorities to invest in early warning systems and resilient infrastructure, especially in vulnerable coastal zones.
The Logical Indian advocates for fostering empathy, knowledge sharing, and solidarity among citizens and policymakers to enhance safety and coexistence with nature’s unpredictability.
