The dramatic changes to the island caused by Irma, the strongest Atlantic hurricane on record, are shown in this pair of images from Landsat 8. Landsat uses shortwave-infrared, near-infrared, and green wavelengths to reveal those changes. The August 27 image shows healthy vegetation as bright green.

Extensive flooding inundated the Gulf Coast of Texas after Hurricane Harvey made landfall as a Category 4 hurricane on August 25, 2017. Among the many waterways in southeastern Texas that exceeded flood stage was the Brazos River, which flows past Houston to its west and to the Gulf of Mexico at Freeport.

A new rift has been forming on Petermann Glacier, Greenland, throughout 2017. An older crack to the right of the new rift also seems to be extending toward the glacier's center. If this new rift meets up with the older crack, and an iceberg breaks off, it would be Petermann's third massive iceberg calving since 2010.

Hurricane Harvey made landfall on the Gulf Coast of Texas as a Category 4 hurricane on the night of August 25, 2017. It then stalled over southeastern Texas as a tropical storm and continued to creep northeast over Louisiana.

It may seem surprising that wildfires burn in Greenland, a huge island of ice and glaciers. But fires do happen there. Earth-observing satellites detected a fire in a remote area of western Greenland in August 2017.

The world's largest continuous hops-growing region by area is Hallertau, just north of Munich. More than 80 percent of Germany's hops come from this 42,000-acre stretch of fertile loess soil.

In northern Brazil, the Belo Monte Dam complex on the Xingu River, a major tributary of the Amazon, has changed the course of the river and surrounding landscape. 

Around July 10–12, 2017, in the middle of the long, dark Antarctic winter, a rift in the Larsen C Ice Shelf broke through the last few miles of ice to the Weddell Sea and formed a new iceberg. The NOAA National Ice Center has given the Delaware-sized iceberg the designation A-68.

An increasingly large gash has opened up in northern Russia's Siberian tundra. During the past few decades, warmer summers and shorter winters have caused permafrost in this region to thaw, which then allows the warmed soils on slopes to slump and erode.

On an average day during the fire season, multiple wildfires burn in the western United States. For example, 216 fires were active on July 7, 2017. Firefighters were battling 27 of these fires through ground and air support.

The Landsat archive, the world's longest continuously acquired collection of space-based, moderate-resolution land remote sensing data, has now surpassed 7 million scenes since Landsat 1 first began collecting data in July 1972.

This image of the Las Vegas /Lake Mead / Grand Canyon area was acquired on June 16, 2017, with Indian Space Research Organization’s Resourcesat-2 AWiFS sensor. Images of this region can be useful to help detect changes in vegetation and water availability for growing desert communities.

How many pictures have you taken with your smartphone? Too many to count? However many it is, Landsat 8 probably has you beat.

A wildfire ignited by lightning in the Okefenokee National Wildlife Refuge on April 6, 2017, is persisting into May. Hot, dry weather and extremely dry fuels are making the fire difficult to contain. As of May 22, the blaze, also called the West Mims Fire, had burned 152,478 acres.

Today Mount Pinatubo is relatively quiet, and about 300 meters shorter than it was before the eruption. This Landsat image pair shows the mountain several months after the eruption and more recently in 2017.

Is Louisiana falling into the sea, or is the sea inundating Louisiana? It's actually a bit of both. To the inhabitants of a tiny island on the bayou, an island getting tinier by the day, it hardly matters.

This image of the New Orleans/Lake Pontchartrain area in Louisiana was acquired March 31, 2017, from the Indian Space Research Organization’s Resourcesat-2 LISS-3 sensor. Land loss and hurricane hazards are key landscape issues here. 

After 5 years of drought, California finally got relief during the winter of 2016–2017 with much needed precipitation. One result of this additional moisture was a springtime abundance of wildflowers.

Solar energy is booming worldwide, and these Landsat 8 images show three large solar energy farms.

Landsat's shortwave infrared (SWIR) band measures reduced moisture content in soil and vegetation. When combined with its near-infrared (NIR) band, which helps reveal actively growing vegetation, Landsat produces highly accurate images and maps of burned areas.

Landsat 8’s shortwave infrared (SWIR) band is useful in viewing recent eruptions at Erta Ale volcano in northern Ethiopia near the Eritrea border.
