Landslides Induced Damages Due to Recent Sikkim Earthquake: Strategies for Geotechnical Intervention
An earthquake measuring M6.8 on Richter scale occurred on September 18, 2011 in the Sikkim–Nepal border (27.723°N, 88.064°E) region. It was widely felt in all the northeastern states of India, West Bengal, Bihar, Uttar Pradesh, Haryana and Rajasthan, including capital city Delhi. National highways and state highways including the rural connectivity in the Chungthang, Lachung and Lachen area have been snapped. Several aftershocks accompanied with incessant rainfall were causing further distress in the relief and rescue operations. As per information received, while BRO (GREF) cleared debris at more than 20 spots along NH31A up to Gangtok within 20 h, followed by road to Mangan, the North District HQ., via Dikchu in 3 days, road to Nathula, the Chinese border, by October 2, and from Mangan to Chungthang by October 18, it will take more time to restore normal road traffic up to Lachung and further north. It is reported that roads so cleared for traffic have not been yet found fit for carrying heavy machineries to many hydroelectric power (HEP) project sites, thus resulting in inordinate delay in their target achievements.
