A massive landslide occurred near Mantam village (opposite the Passingdang– Mantam Road) in Sikkim, India around 13:30 h (IST) on 13 August 2016 (Figure 1 a). The location (at the centre of the zone of depletion) of the landslide was 27°32'22.92"N and 88°30'2.47"E. According to the news reports, formation of a lake and consequent rise in water level had submerged the bridge over Kanaka river and washed away about 300 m stretch of the road. Five houses in Mantam village were also submerged. The villages of Tingvong, Lingdem, Laven, Kayeem, Lingzya, Bay, Sakyong Pentong and Ruklu Kayeem were cut-off due to damage to the connecting road. However, there were no human deaths reported due to the incident.

Abstract


A massive landslide occurred near Mantam village (opposite the Passingdang– Mantam Road) in Sikkim, India around 13:30 h (IST) on 13 August 2016 (Figure 1 a). The location (at the centre of the zone of depletion) of the landslide was 27°32'22.92"N and 88°30'2.47"E. According to the news reports, formation of a lake and consequent rise in water level had submerged the bridge over Kanaka river and washed away about 300 m stretch of the road. Five houses in Mantam village were also submerged. The villages of Tingvong, Lingdem, Laven, Kayeem, Lingzya, Bay, Sakyong Pentong and Ruklu Kayeem were cut-off due to damage to the connecting road. However, there were no human deaths reported due to the incident.
