摘要
On 28 June 1994 when 240 mm of rainfall occurred, a huge debris slide took place at Parmachi village in the Varandh Ghat of the Konkan district on the west coast of India. The debris slide resulted in extensive damage to property and killed 20 people in addition to numerous animals. The slide is considered to have occurred due to the development of hydrostatic pressure at the base of colluvial material, such that slope failure took place at the rock/soil interface. In view of the significance of such slides to settlements and highways, it is proposed that a warning system is developed based on a rainfall threshold of 170 mm in a 24-hour period.
