Recently Sikkim experienced a Glacial Lake _______ Flood in the teesta river basin over Lhonak lake killed seven people. What will come in place of blank space?

### Concept & Terminology The phenomenon described is a Glacial Lake Outburst Flood (GLOF), which occurs when the dam containing a glacial lake fails, releasing a massive volume of water. ### Step-by-Step Solution * The event in Sikkim involved South Lhonak Lake in the Teesta river basin. * Due to heavy rainfall or glacial calving, the natural moraine dam breached. * This sudden release of water is scientifically and officially termed a "Glacial Lake Outburst Flood". * Therefore, "Outburst" fits perfectly into the blank space. ### Exam Strategy & Shortcut Memorize standard geographical and disaster management acronyms. GLOF stands specifically for Glacial Lake Outburst Flood. ### Common Pitfall Confusing standard disaster terminology with generic descriptive words like "Overflowed". While a lake naturally overflows, the specific technical term for this catastrophic event is an "Outburst". ### Final Answer Therefore, the correct answer is **Outburst**.
