Lava Flows Down Mayon
The OLI (Operational Land Imager) on Landsat 8 acquired this rare, relatively clear image of Mayon, the most active volcano in the Philippines, on Feb. 26, 2026. The natural-color scene is overlaid with infrared observations to highlight the lava’s heat signature. On that day, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported volcanic earthquakes, rockfalls, and hot clouds of ash […]
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 […]
