A
landslide, also known as a landslip, is a form of mass wasting that includes a
wide range of ground movements, such as rockfalls, deep failure of slopes, and
shallow debris flows. Although the action of gravity is the primary driving
force for a landslide to occur, there are other contributing factors affecting
the original slope stability. A landslide is the movement of rock, debris or
earth down a slope. Landslides can be triggered by natural causes or by human
activity.

Pinnawala Elephant
Orphanage is captive breeding ground for wild Asian elephants originally
founded in order to afford care and protection to many of the orphaned unweaned
wild elephants found wandering in and near the forests of Sri Lanka. It is in
Kegalle, a district in Sabaragamuwa Province, Sri Lanka. Kankesanthurai is a
town with a harbour, of Jaffna District, Northern Province, Sri Lanka.
Srilankan Met Office
reports that the low pressure area in the Bay of Bengal has intensified in to a
depression and now located to about 400km north of Kankesanturai.It is further
moving away from the island. Hence, rainy weather prevailed over northern part
of the island will be reduced. However, there is a high possibility to sudden
increase of rain in the South-western part of the country and strong windy
conditions over the country and in the sea areas around the island will
continue during next few days due to meeting of wind feeding to the system. The
Office added that there may be temporary
localized strong winds during thundershowers.
That is bad news for
Lankans, affected by severe rains in Colombo after 18 years. Some reports state
that due to unprecedented rainfalll this week, over 300,000 people in seven
districts have been badly inconvenienced. BBC and local media reports suggest
that a record of 440 mm rain was recorded in the city. Many streets were under
water. Floodwater was running from 3-4’ above the road level. Many could not
get out of the houses they live to go to safe places. The Speaker had to limit the Parliamentary session to just
8 minutes and the Parliamentary complex and surrounding areas have been
flooded.
SMH reports that rescuers
are looking for more than 200 families who are missing following massive
landslides in a remote area on the slopes of Sri Lanka’s Central Hills. Agency reports quoting Red Cross stated that they
suspect at least 220 families were missing, going by government population
records. Government officials did not confirm the figure. Seventeen bodies had
already been recovered from piles of mud, a military spokesman said, taking to
36 the confirmed, countrywide death toll attributed to the severe weather and
flooding.
It is stated that rescue operations had been hampered because
roads leading to the mountainous area north-east of the capital, Colombo, were
treacherous. The operations are further hampered by lack of quality
equipments. The Disaster Management Centre (DMC) said
dozens of houses were destroyed when mountain slopes collapsed, forcing
hundreds of villagers to evacuate. The military said dozens of service
personnel and eight army officers had been deployed to the rescue area near the
town of Aranayaka.
“This is the worst torrential rain we have
seen since 2010,” said a DMC spokesman. Nineteen of Sri Lanka’s 25 districts
have been hit. Flooded roads and fallen trees led to traffic jams in Colombo.
Trains were halted as water submerged railway tracks, officials said. Flooding
and drought are cyclical in Sri Lanka, which is battered by a southern monsoon
between May and September, while a north-eastern monsoon runs from December to
February.
Landslide that has caused devastation
is insurable. In Australia, the standard
homeowner policy will not cover damage caused by land movement or a landslide
due to: rain runoff, snowmelt, flooding and earthquakes. There are add-on covers that provide
protection. Back home in India, the
Standard Fire & Special perils Policy names ‘ Subsidence, Landslide and
Rock slide ’ as one among the perils named. Destruction or damage caused to the
property by subsidence is covered. The coastal or river erosion, erosion of
soil etc. are not covered. Claims attributable to improper or faulty design or
defective work of construction will not be within the purview of insurance
policy.
