Before and After Images

Landsat images from March of 2018 and March of 2019 show a stretch of the Missouri, Platte, and Elkhorn rivers in a full scene that stretches from just north of Sioux City, IA, to south of Omaha, NE. The first image shows the rivers at normal levels.

Images from the Sentinel-2B satellite show the impact of 2019 Missouri River flooding on the Midwest. The first image shows the area in March of 2018, with rivers at typical levels. The second shows the Missouri River and its tributaries after heavy flooding. 

Nearly four inches of rain in 30 hours drenched the second-largest city in Afghanistan at the beginning of March, causing flash floods that killed at least 20 people, collapsed homes and swept away moving vehicles.

These Landsat 8 images depict the damage done by the Great Pine Tier fire in Tasmania’s Central Plateau. The first image was acquired on Jan. 13, 2019, three days before the Tasmania Fire Service announced that lightning strikes had ignited dozens of fires across the island state.

Landsat 7 was overhead on Saturday, June 25, 2011 as the Souris River in Minot, North Dakota exceeded the 1881 flooding record by over 4 feet.

These images show the impact of the Gell River fire, which began in December 2018. Landsat 8’s Operational Land Imager acquired the first on Nov. 17, 2018. Clouds cover Mt. Field National Park in the image, rendered using bands 7, 5, and 3.

These Landsat 8 images show the impact of the Riveaux Road fire in southern Tasmania. The first was captured on Nov. 17, 2018, and shows Southwest National Park in shades of green with fragments of brown, with similar patterns apparent in the Barrier Islands of Lake Pedder to the north. By Jan.

This before and after image shows the same area before and after dense trees and brush were cleared for wildfire mitigation efforts. The WiRe (Wildfire Research Team) conducts research to support these mitigation efforts and other components of wildfires and communities.

This is a comparison of photos taken from the same location in the Volcano House on May 19 and June 13, 2018. The focal length of the lens for each photo is almost the same. The photos show the enlargement of Halema‘uma‘u laterally and vertically. Note how much lower the rim is relative to the tree in the lower photo.

North Carolina saw heavy rainfall in the second half of May 2018 as a result of Subtropical Storm Alberto. These images from the European Space Agency's Sentinel-2B satellite, captured on May 12 and June 1, 2018, highlight flooding along the French Broad River near the Henderson County community of Etowah. 

Daylight and fluorescen images of a Orbicella faveolata coral colony in Dry Tortugas National Park. In this colony, the GFP fluorescence is so intense that it overwhelms the weaker red fluorescence of chlorophyll. 

Comal Springs, one of the largest springs in Texas, ran dry during the 2013 drought

Images from the Ferlo region of Senegal show the degredation of land between 1994 and 2011. The images are included in the U.S. Geological Survey Earth Resources Observation and Science Center book "Landscapes of West Africa: A Window on a Changing World." Geographer G.

Radium Spring, Radium Springs Gardens & Historic Site, Dougherty County, Georgia

Radium Springs was once reported to be the largest spring in Georgia flowing 70,000 gallons per minute. As, this "before" picture shows, it still flows when Floridan Aquifer water levels are high enough.

Addicks Reservoir, Houston TX.    Before image (8/29/2017) shows Hurricane Harvey flooding.    Reservoir level was 108.8 feet at the time of the picture; the peak was 109.09 feet on 8/30.    After image (4/6/2018) is eight months after the flooding; reservoir level was 69.45 ft.
