the flow of the landslide was
extreme because of the
extraordinary run-out of mud
and debris
The landslides were triggered
by heavy rains in Badakhshan
province bordering Tajikistan,
where melting snow and sea-
sonal showers make the region
vulnerable to such calamities

but have uplifted plateau margins influenced by neo-tectonic activity. The Hima-
layas mountain belt comprises of tectonically unstable younger geological forma-
tions subjected to severe seismic activity. According to Prasad ( 1986 ), Rao and
Chacko ( 1986 ), Thigale and Khandge ( 1996 ) that landslide activities are increasing
gradually in the Western Ghats, for over 1,200 km, covering parts of Maharashtra,
Goa, Karnataka, Tamilnadu and Kerala. Major landslide locations of Western Ghats
are Ghatkopar (Mumbai), Morbad (Thane), and Panchmukhi (Thiruananthpuram).
Landslide has become an annual phenomenon in the Iddukki and Wynad district of
Kerala as a result of deforestation and soil erosion. Compared to Western Ghats
region, the slides in the Himalayas region are huge and massive and in most cases
the overburden along with the underlying rocks are displaced during sliding par-
ticularly due to the seismic factor. Himalaya is the youngest and highest mountain
range on Earth, which extends over a length of about 2,400 km. It is one of the most
active and fragile mountain chains in the world; it is home to millions of people
