How to Help People During a Landslide in Sri Lanka

Quick answer: To help people during a landslide in Sri Lanka, move away from unstable slopes, report danger to the Disaster Management Centre on 117, call 1990 for an urgent ambulance, and follow the location-specific landslide early warnings published through DMC. Do not enter moving debris, cross a damaged hill road or dig for buried people without trained rescue support. If authorities instruct an evacuation, help the household reach a verified safe site before rain or ground movement blocks the route. Sri Lanka’s landslide agency is now the National Building Research Institute (NBRI), formerly NBRO. Its official technical monitoring helps explain which areas need attention.

Landslide danger in Sri Lanka is particularly relevant in the hill country and other steep wet terrain. A household in Kegalle, Ratnapura, Nuwara Eliya, Kandy or Badulla may be threatened by a different slope, road cutting, drainage pattern or rainfall history from a neighbour two valleys away. The Disaster Management Centre (DMC) publishes dated landslide early-warning reports, and NBRI is the national focal point for landslide risk management and geotechnical work. A warning or map covers particular places and dates; it is not a declaration that all streets in the named district are dangerous.

The order of helping is important. Protect yourself and warn people from safe ground; identify the last confirmed location of anyone missing; contact the appropriate rescue service; then support evacuation, medicines, water, shelter and longer-term recovery. A neighbour who climbs into fresh loose soil may trigger further collapse. Someone who gives DMC or local responders the exact address, road marker and continuing hazards can provide real assistance without risking a second casualty.

First 12 actions when a hillside may be failing

Keep clear of the unstable ground: do not walk beneath a moving slope, onto a visible crack, or across a fresh landslide scar.
Call 117 for disaster-management coordination: provide the district, divisional secretariat, village, road or nearby landmark, and what danger is occurring.
Call 1990 for emergency ambulance care: serious injuries, collapse, breathing distress and other clinical emergencies need qualified assistance.
Report policing or other urgent emergencies through local arrangements: 119 is a recognised police emergency contact, and local officials may specify other response channels.
Check the latest DMC landslide early warning: read the issuing date, valid time, affected district, divisions and warning level.
Warn neighbours from safety: use calls or short accurate messages; do not approach an unstable wall to knock on a back door.
Help people evacuate when required: confirm the authorised safe route and reception site with local disaster or Divisional Secretariat officials.
Do not cross a blocked hillside road: the road may have lost foundations and more rocks may fall.
Be alert to obstructed waterways: landslide debris can block a stream and cause flooding upstream or a sudden surge downstream.
Ask about medical and mobility needs: children, older adults, pregnant people and people with disabilities may require a specific safe plan.
Report trapped people accurately: give last-seen location, number and time rather than circulate speculative casualty lists.
Coordinate recovery through recognised services: organise safe drinking water, food, accessible shelter and medical support when access is permitted.

Sri Lankan contacts and official hazard information

117 — DMC emergency call centre: the Disaster Management Centre’s listed hotline for disaster-related reporting, information and coordination.
1990 — Suwa Seriya ambulance: Sri Lanka’s free nationwide pre-hospital emergency ambulance service for serious medical needs.
119 — Police: police emergency reporting when assistance is required; call the locally designated dispatch point.
DMC warnings: the official landslide early-warning report archive and Disaster Management Centre homepage.
NBRI, formerly NBRO: official agency site for landslide science, risk mapping and technical advice.
1990 Suwa Seriya: official ambulance foundation and emergency access.
Divisional Secretariat, district and local disaster committees: evacuation decisions, verified shelters, road closures and support for affected families.

DMC’s official homepage displays 117 and separate emergency operations centre contacts. The 1990 Suwa Seriya FAQ confirms that 1990 is a free, islandwide pre-hospital emergency service, not a general transport service for routine clinic visits. It may be unable to reach a patient quickly when roads are cut by landslides; report road and access hazards clearly rather than promising a particular arrival time.

Important 2026 terminology: NBRI replaced NBRO

Many older news reports and landslide-warning documents still say National Building Research Organisation (NBRO). The organisation has since become the National Building Research Institute (NBRI) under Act No. 20 of 2025, while the established NBRO name remains familiar to residents. The institute’s official About page confirms the renaming and states that it continues to perform landslide early-warning, hazard mapping, field monitoring and risk assessments.

This matters when sharing instructions: a warning PDF using the NBRO logo may be an official report from the same technical agency, but the reader should still check the issue time, validity, place and current DMC listing. Do not dismiss a genuine older-branded report simply because the organisation’s name changed; and do not circulate an expired PDF as today’s hazard warning.

How to understand the landslide early-warning levels

Sri Lanka’s NBRI/NBRO landslide warnings are published through DMC with distinct levels, affected divisions and validity periods. In general, Level 1 (yellow) asks residents to be watchful; Level 2 (amber) calls for heightened alert and readiness to evacuate; Level 3 (red) calls for evacuation from the specified at-risk area. Do not use a level announced for a different divisional secretariat as evidence that your own location has the same order.

Read the DMC’s dated warning archive rather than an image without the message identifier and valid time. Conditions change as rainfall continues. A Level 1 warning does not mean a specific cracked slope is safe, and a Level 3 warning does not automatically mean every house in the entire district is within the threatened zone. Local directions and technical assessments are essential.

Why rainfall totals alone do not tell the whole story

Rainfall intensity, previous days of rain, soil saturation, drainage, slope angle, rock and soil conditions, road cuttings and previous ground movements all affect stability. A hillside may fail after the heaviest rain stops as water continues moving through the ground. Do not tell a family that the risk has ended merely because the sky is clear for an hour.

Signs to report from a safe distance

New or widening cracks: in soil, roads, retaining walls, house foundations and slopes.
New leaning objects: trees, poles, fences or walls shifting noticeably.
Unusual sounds: persistent rumbling, snapping roots or rocks knocking together.
Water changes: new seepage, muddy discharge, disrupted drains or a change in nearby streamflow.
Road distress: fresh subsidence, bulging pavement, broken culverts, sliding roadside banks or unexpected gaps.
After an initial slide: more falling stones, newly exposed soil or movement above the debris.

These observations are warning signs, not a reliable method of predicting precisely when and where a failure will occur. A landslide can happen suddenly without them. The US Geological Survey’s warning-sign guidance explains common indicators, while Sri Lanka’s NBRI and DMC determine local warnings. Never climb onto a new crack to measure it or stand below a damaged retaining wall to take a photograph.

If a person says they are trapped by moving debris

Ask first whether they can move away from the path safely without crossing new cracks, channels or falling rock. If conditions are already dangerous and escape is uncertain, relay the exact position and hazards to DMC 117, police or the appropriate local rescue team. Call 1990 for serious medical emergencies. Do not tell someone to swim through mud, walk across a damaged bridge or crawl beneath a roof that may collapse.

A useful report includes the district, divisional secretariat, GN division or village, road and kilometre marker, last known position, number of people and injuries. Example: “We last heard from three people beside [landmark], [village], [district] at [time]. Mud is crossing the road, and the upper slope is still dropping rocks. The bridge on [road] may be blocked. Callback [number].” Separate confirmed details from rumours.

Why untrained digging can be fatal

Fresh landslide debris is not a stable mound of dry soil. Heavy boulders, trees, walls and vehicle parts may be resting on other material. Moving the wrong part can trigger further collapse, including onto the trapped person. Trained rescuers must evaluate the slope, access and excavation method. Do not send an untrained family group with shovels or a private excavator into an active failure area. Safe reporting and protecting bystanders are genuine rescue support.

Blocked streams and sudden secondary flooding

A landslide can temporarily dam a river or stream. Water may rise on the upstream side, while lower downstream flow can give a misleading impression of safety. If the debris dam fails, a rapid surge may travel downstream. Keep away from both sides of a suspected blockage, warn from safe ground and report the location. Do not go into the ravine to attempt opening a channel.

Communities near narrow valleys, culverts and bridges should follow DMC, local disaster-management and technical instructions. Another problem is that floodwater can erode the slope beneath a road, making later vehicle crossing dangerous. A road closure remains valid until authorities reopen it, even if the debris has stopped visibly moving.

Helping people evacuate before a hillside collapses

Identify the actual barrier

An older resident may not have transport; a pregnant person may need a clinic; a wheelchair user may need an accessible route; a family may have a child at school or essential medicines indoors. Ask what makes safe evacuation difficult and work with the local Grama Niladhari, Divisional Secretariat and disaster staff. Do not invent a shortcut across a stream or assume every school building serves as an evacuation centre.

Confirm the receiving location

A public building may have been used in a previous disaster but may not be open or safe this time. Verify the current reception site, accessibility, toilets, drinking water, health support and route through the authorised local response. The nearest building is not necessarily outside the landslide or flood hazard zone.

Pack essentials only when it is safe to collect them

Regular medicines and relevant prescriptions.
Mobility equipment, glasses, hearing support and required medical devices.
Phone, charger or power bank and a written family contact.
Identification and important documents when safely within reach.
Safe infant feeding supplies, sanitary products and necessary clothing.
Drinking water and simple food when reasonable and not delaying departure.
Details of the confirmed reception centre and the household’s meeting plan.

Children and separated family members

Keep children with a known safe adult or authorised school or reception staff. Do not send a child across a blocked hillside road to find a parent. If separated, follow official reunification procedures and preserve privacy. Avoid posting a child’s name, medical condition, photograph or exact place of accommodation to open groups.

School or workplace closure notices should come from the responsible authority. A message from one district’s school is not a countrywide closure, and an old screenshot may show an expired warning. When translating across Sinhala, Tamil and English, preserve the division name, warning level, validity period and required action without exaggeration.

Medical treatment and disability support

Serious trauma, crush injuries and breathing problems require qualified medical care. The 1990 Suwa Seriya ambulance service is free for genuine emergencies and operates across Sri Lanka, but mountain roads may delay access. Help by describing the last safe road, nearest landmark and whether a bridge or slope has failed. Do not offer unprescribed drugs or try to pull a person’s trapped limb out from under heavy debris.

If a person needs dialysis, insulin, oxygen or other ongoing treatment, the disruption may become urgent even without a direct landslide injury. Contact their treating healthcare team and authorised disaster coordinator about safe alternate access. A temporary reception centre may not have specialist equipment. Do not ask a family member to carry a patient across a mudslide to keep an appointment.

The first 72 hours of useful recovery assistance

First hours: protect the exclusion area, report missing people accurately and identify emergency medical needs.
Day one: confirm an authorised safe shelter, drinking water, basic food, toilets and necessary medicines.
Day two: assist family communication, health referrals, accessibility and school or work updates.
Day three: help with government assessment, temporary accommodation and access to usable roads, with no promise of grants.
Following weeks: check on continuing slope movement, housing relocation, work, agriculture, water and mental-health needs.

Clean water and food after landslides

Slope failures can damage wells, springs, pipes and irrigation systems and mix soil, fuel or sewage into water supplies. Use a source identified as safe by the responsible water or health authority. Boiling can reduce many microbial hazards when done properly but does not remove all chemicals, fuels or dissolved salts. Food exposed to muddy floodwater or unsafe storage may need to be discarded.

Help families obtain clean covered water containers, functional toilets, soap and appropriate infant feeding supplies. Injuries exposed to mud and debris may need medical assessment to prevent infection. Severe dehydration, persistent diarrhoea, crush trauma or breathing symptoms require professional care. Never force drinks into someone unconscious or unable to swallow safely.

Why recovery may require technical reassessment

A hillside that has already failed may continue moving. Ground supporting a house or road may have shifted or been removed, and later rainfall can reactivate the slope. Reopening may require geotechnical assessment, drainage or retaining works, and sometimes relocation. The NBRI describes its role in hazard mapping, geotechnical stability reports and landslide mitigation. A neighbour’s visual impression is not a substitute for official clearance.

Do not encourage a displaced family to return for furniture or documents until authorised staff say it is safe. Someone who lost access to a medical clinic, school or farm needs practical continuity support even when their home was not buried. Treat the household’s own priorities with respect rather than assuming everyone needs identical emergency goods.

Volunteering and donations safely

Contact DMC, district authorities or a recognised humanitarian organisation before collecting supplies or travelling towards a slide. Technical rescue teams need clear roads, machinery access, medical support and safe staging areas. An unrequested convoy or crowd at a damaged bridge can slow response. If a donation appeal is circulating, verify the organisation, its actual need, receiving point and whether cash or specific goods will be more useful.

Community helpers may support authorised shelter operations, translation, private family check-ins, safe distribution, referral to health services, transport outside restricted zones and longer-term recovery. Untrained excavation, tree cutting beneath unstable slopes and bridge inspection are not suitable volunteer jobs. Protect affected people’s identity information and ask consent before using personal stories for fundraising.

Five realistic situations

1. A family notices a crack behind its house

Tell them not to approach the crack. Ask about rainfall and any official warning, then advise contacting local authorities for immediate assessment. If danger appears imminent, move away from the threatened slope if safe and call 117 or the appropriate emergency service.

2. The main road has a new pile of mud across it

Do not drive or walk across the slide. The road base may be missing and the slope may fail again. Report the exact kilometre marker and wait for the road authority’s reopening notice.

3. Someone is missing after a landslide

Give responders the last confirmed location and time, other people present, any sounds heard and ongoing hazards. Do not announce unverified casualties or start untrained digging.

4. A stream unexpectedly stops flowing after a rumble upstream

It could be blocked by debris, though other explanations are possible. Stay out of the watercourse, warn people from safety and report the exact stream and location. A sudden downstream release can be dangerous.

5. A screenshot says Level 1 while the district authority orders evacuation

Check the date and area: the screenshot may be old or refer to another division. Follow the current local emergency instruction; do not argue that a historic lower warning overrides evacuation.

Frequently asked questions

Who do I call during a landslide emergency in Sri Lanka?

117 is the Disaster Management Centre hotline. 1990 provides free emergency ambulance care. 119 is a recognised police emergency line. Provide the exact location and hazards.

Is NBRO the same as NBRI?

The National Building Research Institute is the successor to the former National Building Research Organisation, legally established under the 2025 Act. Official warnings may still display the former name; verify date and location with DMC.

What does a red landslide warning mean?

The highest warning level calls for evacuation from the specified at-risk areas. Follow the exact division coverage and local officials’ instructions. Do not treat a district-wide map as a street-level route certificate.

Can I cross a landslide if the soil looks still?

No. Loose ground and debris may move again, especially with rain, and roads may be undercut. Follow an authorised safe route.

Can 1990 take someone to a regular clinic appointment?

The free 1990 service is for emergency pre-hospital care, not routine outpatient transport. Contact the relevant healthcare and local support services for non-emergency transport.

How can relatives overseas help?

Maintain private contact, share current DMC and NBRI information, support a verified organisation and avoid unplanned shipments to closed mountain roads.
