Image of the Week - A New Yellowstone Hot Spot

Scientists with the USGS Yellowstone Volcano Observatory use satellite and aerial imagery to map hot springs, geothermal vents, and geysers at Yellowstone National Park. They recently found an entirely new thermal area miles from the nearest trailhead. Landsat 8's thermal infrared sensors captured the change in a nighttime image from April of 2017. Aerial images reveal a quiet emergence over the course of 20+ years.



At the USGS EROS Center, we study land change, operate the Landsat satellites, and maintain the longest, continuously acquired collection of images of the Earth's land surface.
