What's behind the 'shaking' well in Gujarat's Morbi? It's not earthquake

Water in a village well in Gujarat's Morbi district began shaking continuously, alarming residents. Officials said the disturbance appears linked to groundwater recharge after heavy rain, not seismic activity.'Shaking' well in Gujarat's Morbi leaves villagers baffled, probe ordered. (Photo: X)Residents of Gujarat's Morbi district were left puzzled after the water in a village well began shaking continuously, triggering speculation and concern that the unusual phenomenon could be linked to an earthquake.Videos of the rippling water quickly spread on social media, drawing crowds to the site as people gathered to witness the mysterious event.However, authorities have ruled out any connection to seismic activity.District Geologist JS Vadher said preliminary investigations found no evidence that the shaking was caused by an earthquake or tectonic movement. Well water oscillate non stop in Gujarat. Whyy ?This is called well seicheImagine you have a bucket filled with water. If you suddenly shake the bucket once, the water moves left to right left right for some time before becoming still.Now imagine the Earth itself is pic.twitter.com/d26u8mgnPv— Madhu sudhan Reddy Pakala (@MSRPakala) August 7, 2026 "This is not seismic activity. Prima facie, it appears that following heavy upstream rainfall, groundwater is recharging and air trapped in the pore spaces of rocks is being released, causing the disturbance in the well," Vadher explained.According to officials, recent heavy rainfall in upstream areas may have significantly increased groundwater recharge. As water infiltrates underground rock formations, it can compress and force trapped air through fractures and pore spaces. The escaping air may create bubbling and continuous ripples on the water's surface, giving the impression that the well is shaking.Gujarat has witnessed an exceptionally active monsoon season this year, with several districts receiving heavy to extremely heavy rainfall.Successive low-pressure systems over the Arabian Sea and central India have triggered widespread showers, leading to flooding in parts of Saurashtra and Kutch, while also significantly recharging reservoirs, rivers, and groundwater across the state.The explanation is further supported by the absence of any recorded tremors in the region. Officials consulted the Institute of Seismological Research (ISR) in Gandhinagar, which reportedly confirmed that there is no active fault line in the area and no seismic event was detected.Despite the initial assessment, authorities are taking no chances.Morbi District Collector Swapnil Khare said the Gujarat government has been informed about the incident, and a scientific team from Gandhinagar will visit the site to conduct a detailed investigation."We have informed the Gujarat government about it, and a team from Gandhinagar will visit the site for further investigation," Khare said.Experts note that such groundwater-related disturbances, while uncommon, can occur during periods of intense rainfall and aquifer recharge.While officials believe groundwater recharge and the release of trapped air are the most likely explanation, scientists are expected to examine several other possibilities. These include fluctuations in groundwater pressure caused by heavy monsoon recharge, which can create rhythmic movement in well water.Investigators will also study whether the well's unique shape and depth are amplifying subtle underground pressure waves through a phenomenon known as a well seiche or resonance. Another possibility is that the well is connected to an underground fracture or cavity, making it uniquely responsive to changes below the surface.The investigation is expected to determine the precise geological processes responsible for the unusual movement, offering clarity to residents who feared the phenomenon was an early warning of an earthquake.- EndsPublished By: Sibu Kumar TripathiPublished On: Aug 7, 2026 10:49 IST
