Land Is Sliding, Tell Us Where!

Land is Sliding, Tell Us Where!

Summer in the northern hemisphere brings monsoon season, causing heavy rains and flooding that trigger landslides. Next time you see a landslide in the news, online, or in your neighborhood, submit it to our citizen science project Landslide Reporter to build the largest open global landslide catalog and help us and the public learn more about when and where they occur.

Rainfall is the most common cause of landslides.

After a storm, the soil and rock on a slope can become saturated with water and begin to slide downwards, posing a danger to people and destroying roads, houses and access to electricity and water supplies.

We have been monitoring rainfall from space for decades.

Orbiting the Earth right now, the Global Precipitation Measurement (GPM) mission is a group of 10 satellites that measure rain, snow, sleet and other precipitation worldwide every three hours. This data tells us where and when heavy rain is falling and if it could lead to disasters.

What can rainfall data tell us about landslides?

We’re using GPM data to understand where and when landslides are happening. A global landslide model uses information about the environment and rainfall to anticipate where landslides are likely to happen anytime around the world every three hours.

To improve the global landslide model and other landslide research, NASA is looking for citizen scientists like you!

If you find a landslide reported online or in your neighborhood, you can provide the event details in Landslide Reporter, our citizen science project.

Your detailed reports are added into an open global landslide inventory available at Landslide Viewer. We use citizen science contributions along with other landslide data to check our prediction model so we can have a better picture of how rainfall, slope steepness, forest cover, and geology can trigger a landslide.

Because the data is open, anyone can use the data for research or response.

When you report a landslide, you improve our collection of landslide data for everyone.

Help support landslide efforts worldwide by contributing to Landslide Reporter, and you can help inform decisions that could save lives and property today! Learn more about the project at https://landslides.nasa.gov. You can also follow the project on Twitter and Facebook.
