US-Indian Space Mission Maps Extreme Subsidence in Mexico City
One of the most powerful radar systems ever launched into space has mapped the ground moving beneath one of fastest subsiding capitals in the world: Mexico City. The findings show how quickly and reliably the NISAR (NASA-ISRO Synthetic Aperture Radar) satellite can track real-time changes across Earth’s surface from orbit, unhindered by clouds or vegetation […]
See NASA’s GUARDIAN Catch a Tsunami
A new data visualization illustrates how an experimental NASA technology can provide extra lead time to communities in the path of a tsunami. Called GUARDIAN (GNSS Upper Atmospheric Real-time Disaster Information and Alert Network), the software detects slight distortions in satellite navigation signals to spot hazards on the move.. The animation breaks down a real-life […]

NASA’s GUARDIAN Tsunami Detection Tech Catches Wave in Real Time
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 […]
NASA’s Ready-to-Use Dataset Details Land Motion Across North America
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 […]
NASA Satellite Images Could Provide Early Volcano Warnings
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 […]
