Submit Landslides and Help NASA Scientists

Landslides cause billions of dollars in infrastructural damage and thousands of deaths every year worldwide. Data on past landslide events guides future disaster prevention, but to date we do not have a global picture of exactly when and where landslides occur. NASA is building the biggest open global landslide catalog to address this problem, and we need your help!

The Cooperative Open Online Landslide Repository, or COOLR, is an open platform where scientists and citizen scientists can share landslide reports. See all landslide data from COOLR with other scientific data using the Landslide Viewer application. Want to contribute? Add to COOLR using our citizen science application, Landslide Reporter.

With more hands and your help, we can complete the global picture of landslides to prepare for and protect against future disasters. Every landslide submitted by you is another step towards a more predictable future!

COOLR has two applications, Landslide Viewer and Landslide Reporter.

How You Can Submit to COOLR

In order to build a more comprehensive, worldwide database of landslides, we need you!

Building a global landslide inventory is not an easy task and cannot be accomplished without citizen science. As a citizen scientist, you play a transformational role in improving landslide science. The Cooperative Open Online Landslide Repository (COOLR) provides a platform to submit landslides that you find in media, in person, or through other credible means to COOLR. Our goal is to collect as many landslides as we can to enable better research, modeling, prediction, and response.

The main steps to the submission process are:

The submission process
  1. Landslide occurs: A landslide event (see definition in the Primer) occurs and is reported in a newspaper article, online database, or in your local area.
  2. Submit to Landslide Reporter: Using Landslide Reporter, you can add this event to the database and describe its setting, impacts, and details. The Add a Landslide Event Guide takes you through this process step-by-step. When investigating a landslide, the most important thing is to be in a safe place! Do not conduct field work or look at a landslide up close unless you are an expert.
  3. Approval: Our team at NASA checks the incoming landslide reports for accuracy in a best effort basis.
  4. View Your Landslide: Once approved, your landslide event appears on Landslide Viewer alongside other landslide databases like the GLC for the world to see.
  5. Download and Use: Scientists and the public can download the landslide data from Landslide Viewer to use in research, models, and policy work.

Every landslide report made by you is another step towards a more predictable future!

COOLR data analysis options in Layer List

The data from the Cooperative Open Online Landslide Repository (COOLR) can be organized and displayed in several ways on the map. These are the available options in Layer List.

Data Type Description
Landslide Points/Polygons All points or polygons representing landslide events are marked on the map.
Fatalities All points are sized by how many fatalities occurred because of the event.
Time Aware The points can be played in chronological order in the Time Slider.

Using the Time Slider

Time Slider

The Time Slider allows you to pan through landslide events chronologically. To use the tool, a Time Aware layer (you will see the words "Time Aware" next to the layer name) must be selected from the Layer List.

Once a Time Aware layer is selected, click the Time Slider icon in the menu to open the Time Slider panel. You can press “play” to automatically advance the sliders, change the range of dates, and change the speed of the sliders.
