Colombo, 19 May, (Asiantribune.com):

The National Building Research Organization (NBRO) warns people to be watchful on the possibility of landslides, slope failures, rock falls, cutting failures and ground subsidence, since the rainfall within the past 24 hours has exceeded 75mm.

Further, if the rains continue, be on alert on the possibility of landslides, slope failures, rock falls, cut failures and ground subsidence, by being ready to evacuate to a safe location if the need arises, since the rainfall within the past 24 hours has exceeded 100 mm.

People are also asked to evacuate to a safe location to avoid the risk of landslides, slope failures, rock falls, cutting failures and ground subsidence, if the rains continue, since the rainfall within the past 24 hours rains have exceeded 150 mm.

Locations for potential risk and places which need special attention are Galle Four Gravets, Akmeemana, Elpitiya, Niyagama, Bope Poddala and Nagoda, Divisional Secretariat Divisions and surrounding areas, including Baddegama, Neluwa and Thawalama as well as all mountainous areas, manmade cut slopes and roads within the relevant DS divisions.
All the landslide susceptible areas previously identified by NBRO are Matale Ukuwela Divisional Secretariat Division (DSD) and surrounding areas, Ratnapura, Kuruwita, Eheliyagoda, Pelmadulla and Nivithigala Divisional Secretariat Divisions (DSD) and surrounding areas including Ayagama,Rathnapura, Elapatha, Kalawana and Kiriella.

People who live in high hazard areas identified by NBRO, shall be evacuated to safe locations.

They are Kaluthara Horana, and Mathugama Divisional Secretariat Divisions (DSD) and surrounding areas, including Agalawaththa, Palindanuwara, Walallawita, Bulathsinhala and Ingiriya Divisional Secretariat Divisions (DSD) and surrounding areas, Matara, Pitabeddara and Kotapola Divisional Secretariat Divisions (DSD) and surrounding areas, Colombo Seethawaka Divisional Secretariat Division (DSD) and surrounding areas, Kegalle Aranayake and Yatiyanthota Divisional Secretariat Divisions (DSD) and surrounding areas, Deraniyagala Bulathkohupitiya, Warakapola Rambukkana, Galigamuwa Kegalle and Dehiowita Divisional Secretariat Division (DSD) and surrounding areas, Kurunegala Mawathagama and Polgahawela Divisional Secretariat Division (DSD) and surrounding areas, Kandy Gangaihalakorale Thumpane Kandy Four Gravets & Gangawatakorale and Pathahewaheta Divisional Secretariat Divisions (DSD) and surrounding areas, Nuwara-Eliya Kotmale Divisional Secretariat Division (DSD) and surrounding areas, Ambagamuwakorale Divisional Secretariat Division (DSD) and surrounding areas.

These warning levels are issued based on the cumulative rainfall received to respective areas and given weather forecast by meteorological department of Sri Lanka .

Pay your attention to the following pre landslide signs,

? Development of cracks on the ground, deepened cracks and ground subsidence ? Slanting of trees, electrical posts, fences and telephone posts ? Cracks in the floors and walls of buildings which are built at slopes ? Sudden appearance of springs, emerging muddy water, blockage or disappearance of existing springs .

People should move immediately away from the areas where they noticed the above pre-landslide signs.

Furthermore, people living in landslide susceptible areas should be extra vigilant and should be ready to move quickly to safe places if heavy rain continues. Communities are advised to follow the instructions given by National Building Research Organization.

Meanwhile, the Department of Metrology predicts that there could be land problems in the island, especially in Southern, Western, Sabaragamuwa and Central Provinces. Expect rain to continue over the next 24 hours.

In some locations in the Nuwara Eliya, Ratnapura, Kegalle, Kalutara, Galle and Matara districts rains would exceed 150 mm. Expect heavy rains with island wide winds to increase at times (50-60) can be increased. People are requested to take measures to reduce lightening hazards during thunderstorms.
