A three-year drought is threatening to cause city officials in Cape Town, South Africa, to shut off the tap water. The growing city of nearly 4 million relies mostly on reservoirs for its water supply. While drought is part of the cause of the current crisis, an increasing population is also straining water resources.

At least 300 active volcanoes dot the Kamchatka Peninsula, which lies along the geologically active Pacific Ring of Fire. Landsat 8 caught this plume of ash and smoke streaming from one of these volcanoes - Klyuchevskaya - on January 10, 2018.

If you like being connected to the world everywhere you go with a smartphone or other device, then you have a desolate salt flat in northern Chile to thank.

Pine Island Glacier in Antarctica has snapped off its share of icebergs in recent years. The frequency of noteworthy breaks is evidence that the ice shelf is becoming increasingly fragile. The latest iceberg cracked off the end of the Pine Island Glacier ice shelf around September 23, 2017.

This pair of Landsat 8 images shows the large-scale damage done to Puerto Rico. The lush green landscape in the 2016 image is replaced by a faded green. The strong winds stripped the leaves off trees to cause the degraded landscape. The forest is expected to recover.

Hurricane Irma crossed the Florida Keys the morning of September 10, 2017, as a Category 4 hurricane with winds of 130 miles per hour. Besides damage done to structures on the islands, the storm also stirred the waters.

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.

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 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.

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.

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.

Wildfires fueled by dry conditions, high temperatures, and strong winds are scorching central Chile at a level Chilean officials say they haven’t seen in decades.

A decade of drought in California has eased after the first month of 2017 thanks to heavy rains and snow, a fact that Landsat images are helping to confirm.

The Operational Land Imager (OLI) onboard Landsat 8 captured this image an eruption from Ethiopia's Erte Ale volcano in late January of 2017.

Large areas within the Amazon rain forest have undergone large-scale deforestation over the past few decades, and Landsat has helped record this widespread land change.

Images from Landsat 8's Operational Land Imager sensor show the dramatic transformation of the river as it flows toward Cedar Rapids. On July 8, 2016, the shallow river meanders into the city, surrounded by green crops in the heart of the growing season.

On June 28, 2016, a 4,000-foot-high mountainside in Glacier Bay National Park and Preserve collapsed, sending rocky debris equivalent to 60 million mid-size SUVs tumbling onto nearby Lamplugh Glacier.
