Arunachal Pradesh has stepped up vigilance following the flash floods in Nepal, after seven glacial lakes in the Mago area of Tawang district were identified as posing a significant flood risk to downstream populations. The lakes could burst suddenly, triggering what are known as Glacial Lake Outburst Floods (GLOFs).
In response, the Arunachal Pradesh State Disaster Management Authority (SDMA) has launched a major awareness and training programme for communities living downstream of these high-risk glacial lakes.
Key Highlights
- What: Seven high-risk glacial lakes identified in Arunachal Pradesh
- Where: Mago area, Tawang district, Arunachal Pradesh
- Why: Risk of sudden outbursts and flash floods affecting downstream settlements
- Trigger for alert: Recent flash floods in Nepal
- Response: GLOF awareness and training programme by the Arunachal Pradesh SDMA
- Areas covered: Mago village, Doori village and a nearby Indian Army camp
Why Arunachal Is on High Alert
The flash floods in Nepal have prompted heightened vigilance in Arunachal Pradesh. Authorities have identified seven glacial lakes in the Mago area of Tawang district as high-risk because of the potential for sudden outbursts.
If any of these lakes were to burst, the resulting floodwaters could pose a serious threat to people and settlements downstream.
What Is a Glacial Lake Outburst Flood (GLOF)?
A Glacial Lake Outburst Flood (GLOF) is a sudden release of water from a lake formed by a melting glacier. Such lakes are often held back by natural barriers of ice or loose rock debris, which can fail without warning.
When this happens, large volumes of water rush downstream in a short time, leaving communities in the flood’s path with very little time to react. This is why awareness and early preparedness are critical in high-altitude regions like Tawang.
Arunachal SDMA Launches GLOF Awareness and Training Programme
The Arunachal Pradesh State Disaster Management Authority has launched a major awareness and training campaign on GLOF risks for communities living downstream of the high-risk lakes.
Campaign Begins in Mago Village
The campaign began in Mago village. It focuses specifically on high-risk downstream areas, including Doori village and the Indian Army camp located in the vicinity.
What Residents Were Told
During the programme, residents were informed about:
- The locations of the high-risk glacial lakes
- The altitudes of these lakes
- Their distances from local settlements
- The potential dangers of a sudden glacial lake outburst
- The likely impact on downstream settlements
- The estimated time floodwaters would take to reach them after an outburst
Knowing how quickly floodwaters could arrive helps residents understand how much time they would have to move to safety in the event of a GLOF.
Frequently Asked Questions (FAQs)
Why is Arunachal Pradesh on high alert?
Arunachal Pradesh has heightened vigilance after the flash floods in Nepal, as seven glacial lakes in Tawang district have been identified as high-risk for sudden outbursts.
Where are the 7 high-risk glacial lakes in Arunachal Pradesh?
The seven high-risk glacial lakes are located in the Mago area of Tawang district, Arunachal Pradesh.
What is a GLOF?
A GLOF, or Glacial Lake Outburst Flood, is a sudden flood caused when water breaks out of a glacial lake, sending large volumes of water downstream.
Which areas are at risk?
Downstream areas such as Doori village and a nearby Indian Army camp have been identified as high-risk.
What is the Arunachal SDMA doing?
The Arunachal Pradesh SDMA has launched an awareness and training programme to educate downstream communities about GLOF risks, starting in Mago village.
Conclusion
The identification of seven high-risk glacial lakes in Tawang’s Mago area highlights the growing threat that glacial lake outbursts pose to Himalayan communities. With the Nepal flash floods serving as a warning, the Arunachal Pradesh SDMA’s awareness and training drive aims to ensure that residents of Mago, Doori and nearby areas understand the risks and are better prepared to respond if a GLOF occurs.
