BEFORE Know Your Area’s Risk for Landslides You can’t predict big rainfall or earthquake, but you can learn about your area’s risk for landslides. Landslides are more likely to happen in places where they’ve happened before. If your area has experienced landslides in the past, you should be prepared since it’s likely to happen again.
BEFORE ⛔Prepare a Landslide Disaster Plan When a landslide happens, you need to evacuate quickly. Having an evacuation plan that you’ve practiced with your family will help you act fast when every minute counts, providing priority assistance to the PWD, pregnant, elderly and children family members. You should also be familiar with your area’s evacuation routes to help your evacuation go smoothly.

DURING Know the Warning Signs If you’re having a major or heavy, pounding rain, you may be at risk for a landslide. Keep an eye on hilled areas that are more likely to fall, as well as any streams or creeks near you. If the water increases suddenly or goes from clear to muddy, a landslide may be on its way.
DURING
DURING You can also listen for sounds of a landslide, including cracking trees, rushing water, rumbling or the sounds of rocks hitting each other. Listen to the radio or news to stay on top of the latest weather. Evacuate Immediately. If you know a landslide is happening, evacuate immediately. After you’re on the road, another family member can call and warn neighbors and friends.
DURING Be especially careful when driving. Landslides can block roadways or sweep away pavement. Keep your eyes on the road and watch for debris and falling rocks.
AFTER Wait for the All Clear
AFTER Don’t return to the area where a landslide happened until authorities tell you it’s safe. These areas are more likely to experience a slide again immediately after an event. Flooding is also more likely, so seek shelter on higher ground.
AFTER Listen to emergency broadcasts and pay attention to authorities. Focus on helping your neighbours and family as much as you can, but don’t get in the way of emergency professionals. You can also help authorities by reporting any dangers you see, such as: Broken power lines People in need of rescue Ruptured gas lines
AFTER If you or a loved one are injured in a landslide, go to the nearest emergency department (BHC or RHU).
