Uttarkashi floods not due to glacial burst, says space tech firm
Chennai, Aug 7 (UNI) Suhora Technologies, an Earth observation and space data analytics company today categorically said the flash flood in the Uttarkashi region of Uttarakhand is not due to any glacial burst. Ruling out the theory of glacial burst, Suhora Technologies took help of satellite images and data analytics and said the flood is due to a cloud burst. Suhora Technologies examined data from the National Remote Sensing Centre (NRSC) and also its own comprehensive glacial lake inventory along with cross-checking through high-resolution optical imagery to verify that there are no glacial lakes present upstream of Dharali village, thereby ruling out a glacial burst as the cause of the flash floods. The company conducted the analysis using Synthetic Aperture Radar (SAR) and high-resolution optical imagery to identify the disaster-hit zones resulting from this catastrophic event. According to the company, it had acquired Synthetic Aperture Radar (SAR) imagery at 11:01 PM on August 5 through its platform, SPADE, which delivered the image in near real-time, enabling timely and accurate analysis of the disaster. As per the analysis Suhora Technologies said approximately 16 hectares of area have been affected, impacting nearly 148 buildings and resulting in widespread disruption to housing, schools, and public infrastructure. In addition, one bridge has been damaged, and about 0.95 km of road has been affected, leading to significant road closures and interruptions in connectivity. 'This incident is a stark reminder of the increasing vulnerability of Himalayan regions to climate-induced natural hazards, emphasizing the need for proactive policy, planning, and community resilience strategies," said Krishanu Acharya, CEO, Suhora Technologies. "Space data analytics can play a critical role in disaster management and can provide actionable insights to government agencies, policymakers and companies, thereby enhancing their ability to respond effectively and build greater resilience against future disasters,' said Acharya.

The turn that wasn't: How a tampered riverbed turned flood into catastrophe
Two days after a massive mudflow inundated the Dharali village in Uttarkashi, experts are still looking for an answer to pinpoint the exact reason behind the tragedy that has led to at least five deaths and over 60 the verdict is out on the cause of the tragedy, experts are cautioning on why it led to such extensive damage, with hundreds of buildings struck, buried under the debris of mud and loss of life and property could have been exacerbated by encroachment in the riverbed of the Bhagirathi River, according to Prof. K Seshagiri Rao, a renowned geology expert and Emeritus Professor at the Indian Institute of Technology Delhi. Prof. Rao, who was travelling through Rudraprayag, explained that the region experienced heavy rainfall continuously for three to four days, which likely triggered a massive mudflow that struck Dharali. Efforts are being intensified to airlift advanced equipment to Dharali village. (Photo: PTI) RIVEBED ALTEREDWhile mountainous regions often face natural hazards such as cloudbursts, glacier lake outburst floods (GLOFs), and monsoonal mudflows, he emphasised that the scale of destruction seen in Dharali was amplified due to human intervention in the river's natural encroachments and constructions within the riverbed altered the flow dynamics, and when the powerful mudflow struck the built-up areas, it collided with buildings with immense thrust and force, causing catastrophic loss of life and property. The width needed for the mudflow to pass was missing due to construction in and around it, which worsened the disaster. The professor posed critical questions about why constructions in such vulnerable riverbed zones were allowed, highlighting the consequences of unchecked urbanisation driven largely by tourism development in the region. This unplanned expansion into ecologically sensitive and disaster-prone zones has increased the risk exposure of local communities. SATELLITE DATA REVEALS EXTENT OF DAMAGESupporting these observations, recent satellite analyses performed by Suhora Technologies, using Synthetic Aperture Radar (SAR) and high-resolution optical imagery, revealed the extensive impact of the Uttarkashi data, captured at 11:01 PM on August 5, showed approximately 148 buildings damaged and an area of about 16 hectares affected. The imaging also highlighted damage to critical infrastructure, including one bridge and nearly 0.95 km of roadway, leading to significant disruptions in connectivity and emergency Uttarkashi tragedy highlights the urgent need to regulate and enforce land-use policies to prevent encroachment on riverbeds and other high-risk also calls for sustainable urbanisation practices that respect the natural dynamics of mountainous ecosystems to mitigate loss and enhance community resilience against future disasters.

Both areas remain largely cut off due to extensive landslides and multiple road breaches caused by the flash floods.- EndsMust Watch

Satellite reveals hidden environmental crisis in Manipur, Arunachal
Satellites can reveal more about the planet than we can see from the surface.A new satellite based study from Suhora Technologies, a leading Indian Earth observation and analytics company, puts the spotlight on two urgent environmental crises in Northeast India: accelerating deforestation in Manipur and a recent forest fire in Arunachal renowned for its lush forests and biodiversity, is under mounting threat from According to Global Forest Watch, the state lost approximately 17,800 hectares of natural forest in 2024 alone, releasing nearly 9.11 million metric tons of carbon dioxide into the continues a troubling trend of forest decline since latest analysis, covering 2021 to 2025, reveals that Manipur lost around 21,100 hectares of forest during this period. While 13 hectares have shown signs of regrowth, the scale of loss remains drivers of deforestation are complex. Traditional shifting cultivation, or jhum, has become unsustainable due to shortened fallow cycles, reducing the land's ability to recover. Illegal logging, fuelwood collection, and the spread of poppy cultivation further exacerbate forest loss, especially in remote hill areas. Deforestation in Manipur. (Photo: Suhora) advertisementInfrastructure projects like roads and railways, while improving connectivity, also contribute to deforestation and increase the risk of landslides in Manipur's fragile hills. Climate change compounds these pressures by altering rainfall patterns and increasing vulnerability to wildfires and Pradesh: Forest Fire BlazeOn April 24, 2025, a massive forest fire broke out in the Nadipar region near Dirang, West Kameng district, Arunachal Pradesh. Propelled by strong winds, the blaze quickly engulfed several acres, though, fortunately, there were no human casualties or property advanced machine learning algorithms, using daily PlanetScope satellite imagery, detected the fire's impact: 1.09 square kilometers of forest burned, with 0.03 square kilometers still active as of April satellite intelligence is crucial, as many forest fires in remote regions escape timely detection, often leading to severe ecological Acharya, CEO of Suhora Technologies, emphasised that satellite-based analytics provide near-real-time insights, supporting rapid response and better management of environmental crises. 'While the deforestation figures are concerning, the recorded vegetation regrowth offers a pathway forward. There is an urgent need for sustainable land-use practices and community-based forest management,' he findings point to the urgent need for policy action, sustainable management, and technological intervention to safeguard Northeast India's forests for future Watch
