Earthquake In Assam: An earthquake struck Assam’s Morigaon early on Thursday, causing panic among residents, who rushed out of their homes and buildings in fear. Tremors were felt across the state and neighbouring regions. Further details on the magnitude, epicentre, and damage are yet to be confirmed. Authorities are monitoring the situation, and further updates are awaited.
Earthquake Zones In India
India is divided into different seismic zones based on the frequency and potential damage caused by earthquakes. These zones help determine the appropriate seismic coefficients for building designs. The classification is based on geological studies, tectonic activity, and historical earthquake occurrences, with periodic updates as new data becomes available.
In this classification, regions experiencing intensity levels below V are categorized as Zone 0. Delhi falls under Zone IV, which signifies a high seismic risk. Earthquakes in this zone typically range from magnitudes of 5-6, with occasional tremors reaching 6-7, and in rare instances, 7-8. This places Delhi among the areas with considerable earthquake vulnerability.
Earthquakes In India’s History
Since 1720, Delhi and its surrounding regions have experienced at least five significant earthquakes with magnitudes ranging from 5.5 to 6.7 on the Richter scale. Two major geological faults— the Delhi-Hardwar Ridge and the Delhi-Moradabad Fault—run through the region. Both have the potential to generate earthquakes of up to MSK VIII intensity. The estimated depth of such earthquakes is around 30 kilometres.
Given Delhi’s seismic risk, it is crucial to incorporate earthquake-resistant measures into infrastructure planning. A comprehensive strategy focusing on both prevention and preparedness can help mitigate potential damage and enhance the city’s resilience against future seismic events.

Earthquakes occur due to sudden movements of tectonic plates beneath the Earth’s surface. India lies near the collision zone of the Indian and Eurasian plates, making it prone to seismic activity. Some of the worst earthquakes in India’s history include the 2001 Bhuj earthquake, the 1993 Latur earthquake, and the 2015 Nepal-Bihar earthquake. Experts advise residents in earthquake-prone regions to stay alert and follow safety protocols during tremors.
More details to follow. Stay tuned for updates.
