Over 100 low-intensity tremors recorded since 2021, Vijayapura tops list as experts link quakes to monsoon and mining activity
Bengaluru: Karnataka has witnessed a surprising surge in seismic activity, with 114 low-intensity earthquakes recorded between 2021 and 2025, according to data presented by the Ministry of Earth Sciences in the Lok Sabha. The majority of these tremors have been concentrated in North Karnataka districts, raising fresh scientific and public interest.
The districts of Vijayapura, Bidar, and Kalaburagi have recorded the highest number of tremors, with Vijayapura alone emerging as the most active seismic zone in the state.
Fresh Tremors Trigger Panic in Vijayapura
On Wednesday morning, mild tremors were felt across parts of Vijayapura district, particularly in Tikota taluk and surrounding villages. Residents in areas like Kallakavatagi, Babanagar, Bijjaragi, Somadevarahatti, Habanur, and Takkalaki reported brief ground shaking around 8:21 AM, sparking panic.
Border villages in Maharashtra, including Morabagi and Tikkundi, also experienced the tremors.
“We felt the ground shake for a few seconds and immediately ran outside,” a resident said.
Authorities confirmed that no casualties or property damage were reported.
Data Reveals Fluctuating Seismic Pattern
Official data indicates a fluctuating pattern of earthquakes in North Karnataka:
- Vijayapura: 11 (2021), 19 (2022), 6 (2023), 2 (2024), 7 (2025)
- Bidar: 3 (2021), 3 (2022), 7 (2023), 2 (2024), 3 (2025)
- Kalaburagi: 0 (2021), 5 (2023), 4 (2025)
A notable spike was also observed in Ballari, where 7 tremors were recorded in 2024.
In contrast, districts like Mysuru, Dakshina Kannada, and Kolar reported minimal or rare seismic activity.
Why Is North Karnataka Experiencing More Earthquakes?
Experts attribute the rise in tremors to a combination of natural and human-induced factors.
Babloo Choudhary, Assistant Professor at National Institute of Technology Karnataka, explained that:
- Hydroseismic activity during and after monsoon seasons increases underground pressure
- Large-scale mining operations may disturb geological stability
These factors together may be contributing to the frequent low-intensity tremors in the region.
No Immediate Threat, But Warning Issued
Most earthquakes recorded in Karnataka are below 3.0 magnitude on the Richter scale, which are considered minor and generally do not cause structural damage. Events above 4.0 remain rare, and no earthquake above 5.0 has been recorded in recent years.
However, experts caution that a rise in frequency or intensity could signal deeper geological changes.
“While current tremors are not alarming, any increase must be scientifically monitored and studied,” experts warned.
Authorities on Alert
Local administration and disaster management teams are closely monitoring seismic activity, ensuring preparedness in case of further tremors.
A Silent Geological Shift?
The growing number of earthquakes, though minor, indicates a gradual shift in Karnataka’s seismic profile, especially in the northern belt. Scientists stress the need for continuous monitoring, research, and preventive planning to avoid future risks.
