August 2026  \nGlacial Lake Outburst Flood (GLOF)  \nCatastrophic flash floods along Nepal's Bhote Koshi and Trishuli corridor have reignited urgent concerns over Himalayan Glacial Lake Outburst Flood (GLOF) risks and infrastructure vulnerability.  \no GLOF: A sudden and catastrophic release of water from a glacial lake caused by the failure of its containing dam.  \no Glacial Lake: Water bodies formed by melted glacier ice pooling in depressions created by retreating glaciers.  \no Shrinking glaciers leave behind unsupported moraine walls and larger meltwater pools, directly escalating structural instability.  \no Trigger: Outbursts are frequently triggered by ice avalanches, rockfalls, heavy rainfall, earthquakes, or rapid snowmelt destabilizing the lake.  \no Accelerated global warming intensifies glacier melt, rapidly expanding lake volumes and increasing the likelihood of catastrophic breaches.  \no The geologically active, steep terrain of the Himalayas makes the region highly susceptible to sudden and destructive glacial floods.  \no In India, vulnerability is concentrated in the high-altitude Himalayan states, particularly Sikkim, Uttarakhand, Himachal Pradesh, and Arunachal Pradesh.  \no Sikkim: The October 2023 South Lhonak Lake disaster caused massive destruction along the Teesta River basin, highlighting severe regional vulnerability.  \no Uttarakhand: The 2021 Chamoli disaster demonstrated the deadly impact of glacial collapses in steep, fragile valleys like the Rishi Ganga.  \no Ladakh: Rapidly warming high-altitude deserts face emerging threats from expanding pro-glacial lakes previously frozen for most of the year.  \nLine of Actual Control (LAC)  \nIndia and China recently held the 25th Special Representatives dialogue, reaching an eight-point consensus on advancing border management, establishing new hotlines, and pursuing early boundary delimitation.  \no LAC: The demarcation line separating Indian-controlled territory from Chinese-controlled territory, remaining largely un-demarcated on the ground.  \no India-China Border: Spans approximately 3,488 kilometres, broadly divided into the Western Sector, Middle Sector, and Eastern Sector with differing territorial claims.  \no Western Sector: Encompasses the traditional boundary in Ladakh, where major friction points like Galwan, Pangong Tso, and Gogra-Hot Springs are located.  \no Middle Sector: The least disputed segment, covering the borders of Himachal Pradesh and Uttarakhand with minimal major territorial overlaps.  \no Eastern Sector: Centred on Arunachal Pradesh, covering the historic boundary delineated by the McMahon Line which Beijing actively contests.  \no Aksai Chin: A high-altitude desert region in the Western Sector currently administered by China but strategically claimed by India.  \no McMahon Line: Negotiated during the 1914 Simla Convention between British India and Tibet, defining the boundary in the Eastern Sector.  \nIndia's Strategic Petroleum Reserves (SPR)  \nRecently, the Government of India reiterated its focus on expanding energy security by advancing the Phase II development of Strategic Petroleum Reserves at Chandikholand Padur.  \no SPR: Strategic Petroleum Reserves are massive underground stockpiles of crude oil maintained to ensure emergency energy security.  \no Importance: Unlike commercial stocks held by refiners, strategic stocks are sovereign reserves released strictly during national crises.  \no They act as a critical macroeconomic buffer against global supply chain disruptions and unexpected price shocks.  \no Refineries: SPR facilities are strategically connected to major coastal refineries via heavy-duty pipeline networksand port infrastructure.  \no Geography: Coastal locations are chosen to facilitate the rapid offloading of crude oil directly from large maritime tankers  \no Indian Strategic Petroleum Reserve Limited: ISPRL, a special purpose vehicle under the Petroleum Ministry, constructs and manages these facilities.  \no Phase I: The firs","cbCaivSJCWxPqguu","https://ap.wps.com/l/cbCaivSJCWxPqguu","pdf",234291,"English","# Glacial Lake Outburst Flood
