A massive earthquake and subsequent tsunami off Russia in late July tested an experimental detection system that had deployed a critical component just the day before. A recent tsunami triggered by a magnitude 8.8 earthquake off Russia’s Kamchatka Peninsula sent pressure waves to the upper layer of the atmosphere, NASA scientists have reported. While the … Read more
Lee esta historia en español aquí. NASA satellite data and trainings helped Uruguay create a drought-response tool that its National Water Authority now uses to monitor reservoirs and guide emergency decisions. A similar approach could be applied in the United States and other countries around the world. From 2018 to 2023, Uruguay experienced its worst drought … Read more
An online tool maps measurements and enables non-experts to understand earthquakes, subsidence, landslides, and other types of land motion. NASA is collaborating with the Alaska Satellite Facility in Fairbanks to create a powerful web-based tool that will show the movement of land across North America down to less than an inch. The online portal and … Read more
Scientists know that changing tree leaves can indicate when a nearby volcano is becoming more active and might erupt. In a new collaboration between NASA and the Smithsonian Institution, scientists now believe they can detect these changes from space. As volcanic magma ascends through the Earth’s crust, it releases carbon dioxide and other gases which … Read more
NASA researchers conducted initial validation of a new airspace management system designed to enable crews to use aircraft fight and monitor wildland fires 24 hours a day, even during low-visibility conditions. From March 17-28, NASA’s Advanced Capabilities for Emergency Response Operations (ACERO) project stationed researchers at multiple strategic locations across the foothills of the Sierra … Read more
Lava encroaches on the Blue Lagoon, a popular tourist destination in Iceland, in this Nov. 24, 2024, Landsat 9 image overlaid with an infrared signal. The infrared signal helps distinguish the lava’s heat signature. A volcanic fissure burst open on Iceland’s Reykjanes peninsula four days prior, heralded by a series of earthquakes. A plume of gas, … Read more

The Moderate Resolution Imaging Spectroradiometer flying aboard NASA’s Terra satellite took this picture of two cyclones near Iceland on Nov. 20, 2006. Though we usually think of cyclones occurring in the tropics, these spiraling storms can also form at mid- and high latitudes. Cyclones at these latitudes are actually fairly common, and they drive much … Read more
The information will help people who live in coastal areas prepare for impacts caused by rising sea levels. Earth’s ocean is rising, disrupting livelihoods and infrastructure in coastal communities around the world. Agencies and organizations are working to prepare people as their world changes around them, and NASA information is helping these efforts. The agency’s … Read more
Data from NISAR will improve our understanding of such phenomena as earthquakes, volcanoes, and landslides, as well as damage to infrastructure. We don’t always notice it, but much of Earth’s surface is in constant motion. Scientists have used satellites and ground-based instruments to track land movement associated with volcanoes, earthquakes, landslides, and other phenomena. But … Read more
