A mild earthquake of magnitude 3.9 struck Assam’s Udalguri district on Friday, January 30, at 12:20 PM IST, sending light tremors across parts of the state, including Guwahati, and neighbouring Arunachal Pradesh.
Residents in Guwahati reported brief shaking in homes and offices, though there were no immediate reports of damage or injuries, officials said.
A 3.9 magnitude earthquake hit Udalguri, Assam, at 12:20 PM on January 30, with tremors felt in Guwahati and parts of Arunachal Pradesh. The quake occurred at a depth of 10 km, according to the National Centre for Seismology. No loss of life or property damage has been reported.
What the Seismology Data Shows
According to the National Centre for Seismology (NCS), the earthquake was recorded at a depth of 10 km, with its epicentre in Udalguri district.
- Magnitude: 3.9
- Time: 12:20 PM IST
- Latitude: 26.78°N
- Longitude: 92.27°E
- Depth: 10 km
The relatively shallow depth explains why the tremors were felt across a wider area.
Tremors Felt in Guwahati
Though the epicentre was located in Udalguri, mild tremors were felt in several parts of Guwahati, particularly in high-rise buildings and office complexes, where residents noticed brief vibrations lasting a few seconds.
Many commuters and office-goers took to social media to confirm the tremor, while daily activities resumed normally shortly after.
Impact Across the Region
The tremor was also felt in parts of Arunachal Pradesh, officials confirmed. However, no reports of casualties or structural damage were received from any district as of the latest update.
District authorities said they are monitoring the situation but see no cause for immediate concern.
Why Earthquakes Are Common Here
The Northeast region, including Guwahati, lies in one of India’s highest seismic zones, making earthquakes a frequent occurrence.
Seismologists note that low- to moderate-intensity tremors are not unusual in Assam and surrounding states due to active tectonic movement in the region.
What Residents Should Know
Disaster management officials advise residents to remain calm during mild tremors and follow standard safety protocols if stronger earthquakes occur, such as moving away from heavy objects and avoiding panic.
