Landslides

Cooperative Open Online Landslide Repository What is COOLR? The Cooperative Open Online Landslide Repository, or COOLR, is an open platform where scientists and volunteers can share information on landslides. COOLR consists of two main components: Report-based data: Individual landslide reports from various sources, including: The Global Landslide Catalog (GLC), compiled by NASA staff The Landslide Reporter Catalog (LRC), compiled by volunteers Other report-based data, compiled by researchers outside NASA Event-based data: Landslide inventories associated with a specific triggering event or

What was the exact date the landslide occurred? Leave this blank if you are not sure which day it happened. What time did the landslide occur? Enter the approximate time of the landslide in the local time zone. If unknown, leave blank. Where did the landslide happen? This can be a street address, Latitude and Longitude (if known), or general description. Did it cause any damage? How much? Describe any casualties and damage to infrastructure, property, or the environment. Include numbers if possible. How do you know about the landslide? Indicate your source of information, such as personal

Overview: Hydrometeorological natural hazards are on the rise globally, yet in Africa, rainfall data which is crucial in mitigation efforts is lacking. Understanding the amount and distribution of rainfall and how it plays a role in causing these natural hazards is critical to improve disaster response and mitigation efforts. This project uses GPM IMERG data together with resources like NASA's Landslide Viewer to determine a precipitation threshold for landslides in the Mt. Elgon region of Uganda.

The Pacific Northwest coast saw two atmospheric rivers (ARs) bring heavy rains from Nov. 10-16, 2021, resulting in severe flooding, landslides, and damage to infrastructure in the British Columbia province of Canada. ARs are long, narrow corridors of water vapor that travel vast distances above the ocean from warm, tropical regions to higher latitudes, where they often release their moisture as rainfall when they reach land areas. While ARs occur across the globe, this year has been notable for several strong events that have impacted the Pacific Northwest coast. The two atmospheric rivers in

NASA’s Earth observation data are used in a wide variety of ways to improve life for humans and other animals across the world every day. Our climate is changing, and these changes include differences in temperature and precipitation patterns around the globe. As you might imagine, these changes bring about both anticipated and unanticipated consequences that have a profound impact on people around the world. Many organizations are responding to the amazing yet complicated wealth of data that can be used to successfully monitor many aspects of our global environment. The World Resources

On November 3, 2020, Hurricane Eta made landfall as one of the most powerful hurricanes to hit Central America in years. The category 4 storm destroyed hundreds of homes, killed more than 100 people, and brought torrential rains that triggered large and numerous landslides in Guatemala and Honduras. Less than two weeks later, Hurricane Iota—an even more powerful category 4 storm—nearly retraced Eta’s path. Within hours of Eta’s landfall and flooding rains, researchers at NASA’s Goddard Space Flight Center worked to predict landslides and map the storm’s aftermath. One team assessed potential

The extremely active 2020 Atlantic hurricane season, aided by the ongoing La Niña, continues on. After Hurricane Zeta made landfall along the northern part of the Gulf Coast, yet another hurricane has arisen - Hurricane Eta, the strongest of the season. Like Zeta, Eta also formed in the Caribbean, where sea surface temperatures are still running quite warm at around 29° C, almost a full degree above average and well above the typical 26° C needed for tropical cyclone development. But while Zeta turned north into the Gulf of Mexico, Eta moved westward where it delivered powerful winds and

Landslides are a widespread and often underestimated natural hazard, causing thousands of deaths and significant economic damage each year. They routinely block roads, destroy infrastructure, and disrupt communities. Intense or prolonged rainfall is the most common landslide trigger, but earthquakes and human activities can also cause them. Using satellite data, models, and citizen science reports, NASA researchers have developed a collection of tools and datasets to improve our understanding of landslides and help communities around the world monitor, predict, and respond to these destructive events.
