In the last ten years, 69 earthquakes with a magnitude of four or higher have occurred within 300 kilometers (186 miles) of Lucknow, Uttar Pradesh. This equates to an average of six earthquakes annually. In 2023, there were comparatively many earthquakes in the vicinity of Lucknow.
A 3.7 magnitude earthquake was felt in the vicinity of Lucknow, Uttar Pradesh. The National Center for Seismology reports that the shocks’ epicenter was located in Gonda at a depth of 10 kilometers. In two further posts on X, the NCS stated that earthquakes of magnitude 3.4 and 4.4 were also detected in the Xinjiang region and Bageshwar, Uttarakhand, respectively.
Days after a powerful earthquake of magnitude 5.9 struck Myanmar, causing shocks in Kolkata and Dhaka, Bangladesh, these regions are experiencing early morning tremors. Similar to Gonda, the previous earthquake occurred at a depth of 10 kilometers (6.21 miles), according to the German Research Centre for Geosciences (GFZ). The earthquake occurred 70 miles east of Akyab, Myanmar, according to EMSC data.
Bangladesh’s northern and southeast regions are known to be earthquake-prone because of the tectonic plate collision between India and Eurasia.
How earthquake occurs?
Any abrupt earth shaking brought on by seismic waves passing through the rocks of Earth. When energy held in the Earth’s crust is abruptly released, as occurs most often when masses of rock straining against one another unexpectedly fracture and slip, seismic waves are created.
Geologic faults, which are small areas where rock masses shift in relation to one another, are where earthquakes most frequently occur. The world’s main fault lines are found near the edges of the massive tectonic plates that comprise the crust of the planet.
Long-standing concerns like why and how earthquakes occur have been answered by seismology, which is the scientific study of all aspects of earthquakes.
Every year, over 50,000 earthquakes big enough to be detected without the use of instruments take place all across the planet. Of them, about 100 are large enough to cause significant harm if their centers are close to populated regions. On average, really large earthquakes happen once a year. They have caused immeasurable property damage and millions of lives over the ages.
According to the experts, Lucknow is prone to damages due to an earthquake as it lies in Ganga plains, that lessen the severity of the earthquakes by acting as a shock absorber. However, they stated that over the past three decades, the Himalayan Frontal Fault, which divides the Himalayas from the Ganga Plain, has become increasingly active, increasing the frequency of earthquakes in this area.
India is divided into five major seismic or earthquake zones according to the likelihood of damage. Based on observations of the impacted areas, each zone represents the impacts of an earthquake at a location. Zone 5 has the biggest risk, while Zone 1 has none at all.

Although additional research is needed to confirm if groundwater can reduce the intensity of seismic shocks, geologists stated that rapid groundwater depletion is a concern and that early preventive action should be taken.
