Heavy rain from the Habagat, tropical cyclones and prolonged thunderstorms can quickly raise landslide risk in many parts of the Philippines. Families living near steep slopes, road cuts or previously affected areas may have little time to react once the ground starts moving. This guide explains what to do before landslides, including how to check local hazard information, recognize warning signs, plan an evacuation route, prepare a go bag and keep essential communication devices ready.
Quick Checklist: What to Do Before a Landslide
Before heavy rain or worsening ground conditions increase the risk, make sure your household has completed these basic preparations:
Know the risk around your location.
Choose where your household will go and how everyone will get there.
Keep essential supplies and important documents ready to take.
Stay alert to changing weather, local warnings and unusual conditions nearby.
Leave early when the risk increases or local authorities advise evacuation.
Check Whether Your Home or Barangay Is Landslide-Prone
Start by checking your home, workplace, school and usual travel routes, especially if they sit near steep slopes, road cuts, gullies or areas that have experienced previous slope failures. A general barangay rating may not reflect every street or access road, so check each location that could affect your household during an evacuation.
Two government tools can provide an initial view of local landslide exposure:
HazardHunterPH: Search for an address or select a point on the map, then review the Rain-Induced Landslide (MGB) result. You can also generate a location-specific report with explanations and recommendations.
MGB Geohazard Map Portal: View detailed rain-induced landslide susceptibility zones prepared by the Mines and Geosciences Bureau. The portal classifies mapped areas as low, moderate, high or very high susceptibility and also identifies possible debris-flow paths or accumulation zones.
Prepare Your Household to Evacuate Early
A useful evacuation plan should tell every household member where to go, which route to take and what to carry. Complete these decisions before heavy rain affects local roads, since leaving late can expose the household to blocked access routes, poor visibility and moving debris. Use the following questions to build a practical plan:
What to Plan | What Your Household Should Confirm |
Safe destination | Which evacuation center has the barangay or LGU assigned to your area? |
Primary route | Which route avoids steep road cuts, gullies and known landslide or debris-flow zones? |
Alternative route | How will you leave if debris, flooding or a road closure blocks the usual route? |
Household roles | Who will assist children, older adults, pregnant family members, persons with disabilities and pets? |
Transport | Who can provide transport for family members who cannot leave independently? |
Communication | Where will everyone meet if phone networks fail or family members evacuate from different locations? |
Essential items | Who will carry medicines, documents and the household go bags? |
Confirm the evacuation site with your barangay or local DRRMO. Do not assume that the nearest school, covered court or public building will open as an evacuation center or sit outside the hazard zone.
Also, prepare a manageable go bag that you can collect without searching for separate items. Include:
drinking water and ready-to-eat food;
a first-aid kit, maintenance medicines and copies of prescriptions;
copies of IDs and essential medical information in a waterproof pouch;
a flashlight, spare batteries, portable radio, phone charger and power bank;
rain protection, suitable footwear, clothing and hygiene supplies;
small-denomination Philippine peso notes and a whistle;
additional supplies for infants, older adults, persons with disabilities or pets.
Monitor Rainfall and Landslide Advisories
Check official updates regularly during the rainy season, Habagat episodes and tropical cyclones. PAGASA rainfall warnings indicate when flooding and landslides may become possible, threatening or serious in susceptible areas, giving households and local authorities more time to act.
Understand PAGASA Rainfall Warnings
PAGASA uses a color-coded warning system to signal rainfall intensity and flood and landslide hazards. Monitor these colors on official news broadcasts or social media channels:
PAGASA Warning | What It Means for Landslide-Prone Areas | What Households Should Do |
Yellow Warning | Flooding and landslides are possible in susceptible areas | Continue monitoring updates and make sure your evacuation plan and go bag are ready |
Orange Warning | Flooding and landslides are threatening in susceptible areas | Contact your barangay or local DRRMO for instructions and prepare to leave if pre-emptive evacuation begins |
Red Warning | Serious flooding and landslides are expected in affected susceptible areas | Take immediate safety precautions and follow evacuation instructions without delay |
Follow Official Weather and Local Emergency Channels
Rely on verified local disaster agencies rather than unverified social media posts to make safety decisions:
PAGASA Updates: Check Heavy Rainfall Warnings, Tropical Cyclone Bulletins, Weather Advisories for the Habagat or low-pressure areas, and local Thunderstorm Advisories.
Mobile Disaster Alerts: Keep your phone charged and make sure government or emergency alerts remain enabled. Telecommunications providers may send location-targeted warnings under the Free Mobile Disaster Alerts Act, but households should not rely on mobile alerts as their only source of information.
Local Announcements: Follow warnings delivered through barangay sirens, loudspeakers or bandillo announcements, patrol vehicles, official social media pages and door-to-door notifications.
Safety Tip: Landslide risk may remain elevated after the rain weakens because slopes can stay saturated. Continue following PAGASA, MGB and LGU updates.
Recognize Landslide Warning Signs and Act Early
Some landslides produce visible or audible warning signs, but others can occur with little notice. Recognizing these subtle warning signs in your immediate environment gives your family time to evacuate before soil movement becomes destructive.
Warning Signs Around Your Home and Nearby Slopes
Watch for unusual changes from a safe location during and after heavy rainfall. Do not approach cracks, unstable retaining walls, steep road cuts or areas where soil and rocks have begun to move:
Where You Notice the Change | Warning Signs to Watch For |
Ground and slopes | New or widening cracks, small soil slips, falling rocks, sunken road surfaces or unusual ground movement |
Water and drainage | New seepage, saturated areas that are normally dry, rapid changes in creek levels or clear water suddenly becoming muddy |
Trees and structures | Leaning trees, posts, fences or retaining walls; doors and windows suddenly sticking; stairs or paths pulling away from the building |
Sounds and movement | Increasing rumbling, snapping roots, cracking timber or rocks striking one another |
What to Do Immediately When You Spot Warning Signs
Leave the exposed area: Use the safest available route away from the slope, gullies and possible debris paths. Do not approach cracks or moving material for a closer look.
Follow local instructions: Obey evacuation directions from your barangay, LGU or local DRRMO, even when the slope has not yet visibly failed.
Report what you observed: Once safe, contact local authorities and describe the cracks, movement, unusual water flow or sounds you noticed.
Alert others without delaying evacuation: Warn nearby households by phone, message or verbal call when this does not place you at additional risk.
Nighttime Caution: If your home lies in a high-susceptibility area and PAGASA issues an Orange or Red rainfall warning overnight, check the latest instructions from your barangay or local DRRMO before going to sleep. Leave promptly if authorities begin pre-emptive evacuation or warning signs appear nearby.
Keep Communication and Essential Power Ready
Heavy rain and landslides can damage power and telecommunications infrastructure or prevent repair crews from reaching affected areas. Before conditions worsen:
fully charge mobile phones, power banks, rechargeable lights and other essential devices;
save evacuation information, household contacts and important advisories for offline access;
keep a battery-powered radio with spare batteries so your household can still follow official announcements if mobile data or local networks become unreliable;
write down Unified 911, your city or municipal DRRMO, and your barangay contact on a card stored in a waterproof pouch.
Backup Power Solutions for Extended Outages
Small power banks can recharge phones, but they cannot support larger household devices. During an extended outage, prioritize communication equipment, lighting, internet access, refrigeration and other compatible essentials before allocating stored power to high-consumption cooking equipment or non-essential appliances. A portable power station can bridge this gap by supplying stored electricity to selected household devices when the grid is unavailable.
The EcoFlow DELTA 3 Max Portable Power Station can support selected small appliances during a blackout. Its fast UPS switching helps compatible devices stay powered when grid electricity fails, and its portable design makes it easier to position the unit where essential equipment needs power.
For households expecting longer outages or greater energy needs, the EcoFlow DELTA Pro Portable Power Station offers expandable energy storage for running more selected appliances over a longer period. Even when the main grid is still unavailable, it can be quickly recharged using solar energy, helping maintain a continuous and independent power supply.
What to Do During and After a Landslide
What to Do During a Landslide
If ground movement has already begun but a safe route remains open, move away from the unstable slope, its base and any gullies or stream channels that could carry debris.
If debris is already striking the building and leaving would place you directly in the moving material, move to a protected interior area on the highest safely accessible floor, stay away from windows and exterior walls, and cover your head.
Never walk or drive through moving mud, rocks, soil or water. Avoid steep slopes, road cuts and channels where debris may travel.
When driving, slow down and turn around if rocks, mud or collapsed road sections block the route. Do not stop beneath steep roadside slopes or ignore official road closures.
What to Do After a Landslide
Stay away from the affected area because continued rain may trigger additional slope movement. Avoid damaged roads, unstable slopes, stream channels and buildings near the debris zone.
Help injured people only when you can reach them without entering an unsafe area. Provide first aid within your level of training and contact emergency services for medical or rescue support.
Report blocked roads, new ground cracks, damaged drainage, broken utility lines, leaning poles or continued soil movement to your barangay, local DRRMO or utility provider.
Keep away from fallen power lines, exposed wiring and standing water near electrical equipment.
Return home only after local authorities confirm that the property and access route are safe.
Ask qualified personnel to inspect serious structural damage and affected electrical, water or LPG systems before using them again.
Conclusion
Landslides can develop quickly, leaving very limited time to react once they begin. That is why knowing what to do before landslides is so important when conditions begin to deteriorate. Simple preparation, early awareness of warning signs, and having a clear emergency plan can make a real difference when conditions become dangerous. In high-risk areas, especially during the rainy season, these preparations and early decisions can significantly reduce damage and help protect lives and property.
FAQs
Can light rain trigger a landslide?
Yes. Light rain may trigger slope movement when earlier prolonged rainfall has already saturated the soil or when the slope has existing cracks, poor drainage or disturbed ground. You should consider recent rainfall and warning signs together rather than judging risk only by the rain falling at that moment.
Is it safe to stay in a house during a landslide warning?
Do not stay if your barangay or LGU has ordered evacuation or if the property shows signs of slope movement. If debris is already moving and leaving would place you directly in its path, move to a protected interior area and wait for official instructions or rescue.
Can planting deep-rooted trees or bamboo completely stop landslides on my property?
Deep-rooted vegetation can reduce surface erosion, but it cannot guarantee slope stability. Prolonged rain may saturate soil and weathered rock below the root zone, so vegetation alone cannot prevent a deep-seated slope failure. Drainage, land-use controls and professional slope assessment remain important parts of how to prevent landslides.
