SRINAGAR: On March 30, 2026, the Jammu and Kashmir government informed the Legislative Assembly that the entire Union Territory had been placed -in Seismic Zone VI, the highest risk category under India's newly notified earthquake design code, IS 1893 (Part 1): 2025.
Responding to a starred question from MLA Salad Shaheen, officials confirmed that the revised Bureau of Indian Standards classification treats all districts across J&K as uniformly and maximally vulnerable, with no internal gradation of risk.
Structural audits are now underway, over 11,600 school buildings have been assessed following the 2025 floods, and a committee has been constituted to conduct a full Hazard, Vulnerability and Risk Assessment of the territory. An earthquake early warning system, officials acknowledged, remains at a nascent stage.
The government's disclosure, significant as it is, concerns administrative classification and preparedness machinery. It does not, in itself, explain why Kashmir sits at the apex of seismic danger or why the threat may be deepening.
For that, a peer-reviewed study published just months earlier in Physics and Chemistry of the Earth provides the most comprehensive accessible scientific account to date.
The paper, "Earthquake hazard: A silent crisis in Kashmir valley, NW Himalaya" by Ayaz Mohmood Dar of the Indian Institute of Science, Bangalore, draws on seismological data, geophysical field surveys and structural engineering simulations to build a multi-layered picture of Kashmir's earthquake vulnerability.
Its conclusions are worrying. While the government's reclassification covers the entire Union Territory, Dar's study focuses specifically on the Kashmir Valley.
A Valley Built on Seismic Tension
The fundamental source of Kashmir's earthquake hazard lies beneath the surface, in the slow but inexorable collision of two of the Earth's largest tectonic plates. As Dar's paper explains, the Himalaya formed through the northward drift of the Indian plate and the southward movement of the Eurasian plate, a process of continental collision that began the subduction of the intervening neo-Tethyan oceanic crust over 200 to 50 million years ago.
That collision has never stopped. The forces it generates continue to accumulate in the crust, and Kashmir Valley sits squarely in their path.
The valley is described in the paper as an intermontane basin - a depression enclosed by mountains - developed along what scientists call the Kashmir Seismic Gap, which the study identifies as "one of the most tectonically significant yet historically under-ruptured regions of the Himalayan arc."
The words "under-ruptured" mean that the seismic energy building along this section of the Himalayan plate boundary has not been released in proportion to the forces accumulating there. The gap is not a zone of quiet; it is a zone of accumulating debt.
The valley is encircled by a dense network of major fault systems. The paper notes that the Kashmir basin is surrounded by the Himalayan Frontal Thrust, the Main Boundary Thrust, the Main Central Thrust, the Main Mantle Thrust, and the Kishtwar Fault, among numerous lesser faults.
The Himalayan Frontal Thrust is described as "one of the greatest fault systems" associated with large historical earthquakes and intense ground motion. The Main Central Thrust, locally known as the Panjal thrust, shields the valley from the west and is identified as "one of the principal tectonic scars in the region," dipping steeply at 45 to 55 degrees toward the northeast. Running beneath the valley floor is the Balapur fault, whose activity Dar investigates in forensic detail using ground magnetic surveys.
Thousand Years of Catastrophe
The paper's historical record leaves little room for comfort. Kashmir's earthquake history is not a sequence of occasional shocks. It is a near-continuous chronicle of major seismic events stretching back over nine centuries.
The study catalogues significant earthquakes in and around the valley from 1123 onwards. In 1555, a magnitude 8 event struck Jammu and Kashmir, described elsewhere in the scientific literature as the largest earthquake recorded in the region.
The paper recounts that it "occurred at around midnight, collapsed many houses in Srinagar, toppling some into the river, and was accompanied by fissuring and ground cracks."
Large earthquakes also struck in 1669 (M 7), 1678 (M 6.8), 1736 (M 7), 1779 (M 7.5), 1784 (M 7.5), 1828 (M 7.5) and 1885 (M 7.5 at Baramulla). In 1905, the Kangra earthquake devastated the wider northwest Himalayan region.
More recently, October 2005 earthquake most powerfully shaped modern awareness of the region's vulnerability. With its epicentre in Muzaffarabad, in Pakistan-administered Jammu and Kashmir, its magnitude was 7.6. It killed more than 80,000 people, injured nearly 200,000, left 3.5 million homeless, and killed 19,000 children, "mostly due to building collapses" across the two sides of the Line of Control.
The paper makes clear that this history is not an argument that the worst is past. Citing Bilham (2019), it notes that "geology and historic study reveal that the Himalaya will witness much larger earthquake events than the 2005 event" and that scientists, "based on the massive scale of faults in the Himalayan arc and enormous forces," consider large magnitude earthquakes inevitable.
Bilham's analysis cited in the paper evaluated the slip potential for 15 Himalayan fault segments and found that 10 of the 15 are currently mature to host earthquakes of magnitude 8 or greater.
When Not If
Using Extreme Value Theory and the Gutenberg-Richter methods to Kashmir region’s seismic data from 1905 onwards, the study establishes estimates about how frequently earthquakes of different magnitudes are likely to occur.
The analysis estimates that earthquakes of magnitude 6 or above recur roughly every 6 years in the region, and events of magnitude 6.5 or greater recur every 19 years. The probability of an earthquake of magnitude 6.5 or below occurring within any 20-year window is calculated at 100 percent. Looking further up the magnitude scale, the study finds "there are approximately 40 percent chances to have an earthquake event of Mw ≥ 7.6 in 100 years," and that the recurrence interval for a magnitude 7.6 event is around 200 years.
Given the 2005 Muzaffarabad earthquake, another event of that scale falls within the range of statistical expectation within this century. An earthquake of magnitude 8 or greater has a recurrence interval of approximately 380 years.
The study clearly states that "the occurrence of high earthquake magnitude in future can't be ruled out."
Active Faults Beneath the Valley Floor
Dar conducted Total Magnetic Intensity (TMI) surveys along the strike of the Balapur fault, confirming active fault processes. The paper reports that fault magnetization reflections were found associated with magnetic minima, which the analysis attributes to oxidation and martitization, chemical changes that reduce iron-bearing minerals from magnetite to hematite at fault rupture zones. These are fingerprints of past and ongoing fault movement.
Magnetic minima were recorded along the entire strike of the Balapur fault, with a long, nearly linear magnetic transition oriented southwest to northeast representing what the paper calls "the reflection of magnetic lineation at the Balapur fault."
Three-dimensional susceptibility mapping further revealed "the presence of linear low magnetic zones, therefore active fault-related anomalies." The paper concludes that "the reflection of magnetic minima's of total magnetic intensity data and seismological data portray that the Balapur fault is vulnerable to earthquakes."
Ground That Cannot Hold
A further layer of danger, less discussed in public discourse but extensively examined in the paper, concerns the nature of the soil on which much of Kashmir's built environment sits.
The Kashmir Valley is an enclosed basin filled with thick Quaternary lacustrine and fluvio-deltaic sediments, which are essentially ancient lake and river deposits. When seismic waves pass through such soft, water-saturated ground, a process called liquefaction can occur. The soil temporarily loses its strength and behaves like a liquid, causing buildings to sink, tilt, or collapse even if the shaking itself is not extreme.
The paper cites research finding that "soils of major civil infrastructural regions like Baramulla, Kupwara, and Srinagar have very high to high liquefaction potential index (LPI) values."
The valley has a notably shallow water table, ranging from 1.5 to 4 metres below ground level in summer, and 1.75 to 6 metres in winter. This proximity of groundwater to the surface maximises liquefaction risk.
The devastating 2014 floods, the paper notes, contributed to groundwater fluctuations and are themselves considered "agents for soil liquefaction and ground shaking amplification." The study warns that "liquefaction of saturated, loose alluvial and lacustrine deposits can produce large ground deformations that can severely damage foundations, even when peak ground accelerations are moderate".
This could mean that even a moderate earthquake could prove catastrophic in areas like central Srinagar.
A Flawed Building Model
The most urgent dimension of the paper's findings concerns what has been constructed on this vulnerable ground.
Dar's building simulations, conducted using standard engineering software in compliance with Indian seismic codes, demonstrate that significant lateral loads with horizontal forces generated by ground shaking act on both residential and institutional buildings in the Kashmir Valley.
For a typical three-story institutional or commercial building, the analysis found lateral loads reaching 749 kN in one direction, with combined base shears of over 11,000 kN.
The problem is that most existing structures were not designed to handle such forces. Field investigations cited in the paper reveal that "most of the built-up in the Kashmir valley are constructed using concrete material with a shallow foundation" and that the platforms of these structures "directly repose on the ground without proper foundation evaluations."
Load-bearing concrete wall structures, now the dominant construction form, "may lack seismic strategies despite high seismic risk." Settlements in hilly regions and on river terraces face compounded risk from slope instability.
The paper notes the historical existence of two traditional Kashmiri construction methods - Dajji Dewar and Taq - which use timber-framed walls with masonry infill and demonstrate "tremendous resilience against lateral forces."
These systems, the paper observes, have largely been abandoned in favour of modern concrete construction. The study states plainly that "the endorsement of these structural systems seems lacking whereas the risk based concrete structures with indecorous seismic guidelines continue to shape the earthquake-related revulsion in the Kashmir valley."
A Silent Crisis, An Overdue Response
The Kashmir Valley, Dar's paper concludes, faces a convergence of risks: active fault systems surrounding and underlying it, a seismic gap accumulating unreleased energy, soft water-saturated soils primed for liquefaction, a built environment largely unprepared for the lateral forces a major earthquake would generate, and a population that has grown substantially in recent decades, expanding the urban footprint directly into the most vulnerable zones.
The paper states that "the earthquake activity in the Kashmir valley remains a silent crisis and therefore there is an urgent need for risk-based design decisions and disaster mitigation policies."
The government's reclassification of the entire Union Territory under Seismic Zone VI, and the infrastructure audit now underway, represent the most explicit official acknowledgement. Yet this crisis can no longer be treated as silent.
Whether the pace of structural retrofitting, the progress on an early warning system, and the enforcement of earthquake-resistant building codes can match the scale of the hazard that the experts describe is the more crucial concern.
