Case study of an landslide
Answers
A massive landslide wiped out the village of Malin located at 110 km from Pune city, in the Western Ghats on July 30. Mound of mud and debris that came down from a nearby hillock, swallowed up almost the entire tribal village of around 50 families. Due to the remoteness of the village, the tragedy came to light only when the driver of the first state transport bus reached the village a little after 7.30 am to find it uprooted. Final death toll was 153 when the rescue operation was stopped and around 100 people were missing. This tragedy has brought the focus back on the management –or mismanagement – of the vulnerable hills of India especially Western Ghats, Himalayas and North Eastern states There are many speculations about what caused such massive landslide. In this paper we are analyzing geotechnical aspects of the catastrophe. Some of the key facts to note are, heavy rainfall before the landslide (10.8 cm on July 29) and heavy downpour throughout the following day. This calamite is a lesson for sustainable geotechnical planning in future to avoid massive loss of human life and property. Detailed analysis of geotechnical facts is carried out and an attempt is made to pinpoint the cause and preventive measures are suggested.
