After fresh landslide in river Yarlung-Tsangpo in Tibet, creating another fear of fresh flood in river Siang in Arunachal Pradesh.



Barely two weeks have passed, when the people of Arunachal Pradesh living along river Siang have taken sigh of relieve from threat of massive flood, another landslide has blocked the river Yarlung-Tsangpo again at the same location at Milin Section in Tibet, creating another fear of fresh flood in river Siang in Arunachal Pradesh.

The information of fresh landslides has come from the Central Water Commission (CWC),  who has received the information shared by the Chinese Govt. As per the information provided by China, the landslides struck the Milin Section of river Yarlung-Tsangpo on 29th October 2018 at about 1100 hrs. The landslides has caused partial blockade of river Yarlung-Tsangpo. It appears the water is passing over the blockade. No details information is available regarding the magnitude of the landslides or the lake formed due to the blockade.  The height of the barrier could not be ascertained, which could have given estimate of the water collected or the threat of the lake.

 However, from the information available, it appears the landslides are smaller than the landslides that struck the area on 17th October 2018. The water that has accumulated and lake formed is also half the size of 17th October 2018. Bidol Tayeng, Secretary (Disaster Management) said “the water is flowing down the down stream of Arunachal Pradesh, which is a relief as no big lake is expected to be formed. The slight decline in the river water last night is not a matter of much concern”.

As a result of the landslides, the water level of river Siang has declined by 1.44 mt between 10.00 PM- 11.00 PM last night on 29th October 2018 at Tuting in Upper Siang district. After the declined, the water level is stable today.

The Department of Disaster management, Itanagar has alerted the districts through which the river Siang is passing through. The DCs have convened emergency meetings with Officials and public in their respective districts to meet any eventualities. The DCs have alerted people living along river Siang about the landslides and possible rise in level of water of river Siang. They have been asked to restraint from going to river for fishing, swimming, boating or picnic etc. ADC, Tuting, where the flood water will enter India first in case of burst of lake, has set

up control room to monitor the water level throughout the night.   Bidol Tayeng, Secretary (Disaster Management) said “We are in constant touch with the Deputy Commissioners and monitoring the situation from Itanagar. We are also in constant touch with the Ministry of Home, Govt. of India for more information on the situation from the Chinese Govt.  We have asked for more information on the magnitude of blockade and the size of the lake.  We are hopeful of getting more information from satellite or the Chinese side tomorrow”.
