An earthquake of magnitude 4.7 hit the Andaman Sea on Monday morning, according to the National Centre for Seismology (NCS). As per the NCS, the earthquake occurred at 10.09 am at a depth of 10 kilometres. Earlier on June 25, an earthquake measuring 4.2 on the Richter scale struck the Andaman Sea, according to the National Centre for Seismology (NCS).(Pixaby/ Representational Image)
In a social media post on X, the NCS wrote, 'EQ of M: 4.7, On: 30/06/2025 10:09:03 IST, Lat: 9.43 N, Long: 94.17 E, Depth: 10 Km, Location: Andaman Sea.'
Earlier on June 25, an earthquake measuring 4.2 on the Richter scale struck the Andaman Sea, according to the National Centre for Seismology (NCS).
As per the NCS, the quake occurred at 01.43 am at a depth of 20 km, with its epicentre located at 9.46°N latitude and 94.07°E longitude.
"EQ of M: 4.2, On: 25/06/2025 01:43:50 IST, Lat: 9.46 N, Long: 94.07 E, Depth: 20 Km, Location: Andaman Sea," National Centre for Seismology wrote on X.
The Andaman Sea and the Andaman and Nicobar Islands fall within Seismic Zone V, the highest risk zone in India. The Alpine-Himalayan seismic belt extending up to the Andaman-Nicobar island region is known to be one of the seismically active belts of the world, according to the Ministry of Earth Sciences.

Earthquake today: Three successive quakes jolt Andaman Sea, latest seismic activity measures 4.7 magnitude
Earthquake today: Three successive quakes jolted Andaman Sea on Monday. The latest earthquake measuring 4.7 magnitude on the Richter scale jolted Andaman Sea on June 30, according to National Center for Seismology (NCS). As per the report, the third seismic activity was felt in the region at 12:06 AM. The quake occurred at a depth of 10 km. 'EQ of M: 4.7, On: 30/06/2025 12:06:25 IST, Lat: 9.60 N, Long: 93.79 E, Depth: 10 Km, Location: Andaman Sea,' the NCS said in a post on X. The first seismic activity of 4.7 magnitude was reported around 10:09 AM which was followed by two aftershocks. The second quake was reported around 11:22 AM. Notably, the second and third quakes happened within an hour. The NCS in a post on X informed that the first earthquake struck Andaman Sea on Monday at a depth of 10 km. 'EQ of M: 4.7, On: 30/06/2025 10:09:03 IST, Lat: 9.43 N, Long: 94.17 E, Depth: 10 Km, Location: Andaman Sea,' the NCS said. Tremors measuring 4.6 magnitude followed at the same 'shallow' depth and location. In a post on X, the NCS stated, "EQ of M: 4.6, On: 30/06/2025 11:22:23 IST, Lat: 9.45 N, Long: 93.93 E, Depth: 10 Km, Location: Andaman Sea." Shallow earthquakes are more dangerous than deeper ones as they are often followed by aftershocks. This happens because shallow earthquakes release greater energy release closer to the Earth's surface which is destructive. Hence, shallow quakes have higher potential of causing damage to structures and casualties due to stronger ground shaking.
