Image of the Week - Southern California Wildfires, December 2017
The Thomas fire has burned more than 230,000 acres and continues to blaze across souther California. These images show some of the burn scar left behind.
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.

Landsat in Action - Changing Forest Phenology with Andrew Elmore
When parking lots go up, when rooftops multiply, land cover and land uses change. Professor Andrew Elmore with the University of Maryland’s Center for Environmental Science understands that very well, and explains how he uses Landsat to study and quantify that change in USGS EROS’ latest “Landsat in Action” video conversation.

Image of the Week - New Rift on Greenland's Petermann Glacier
A new rift is forming across the Petermann Glacier. If this rift connects to existing rifts, it could result in another large iceberg breaking free.

Every Pixel - Ground Stations
Every pixel of Landsat data is transmitted down to a network of ground stations around the world. Here is an overview of how that happens.

Every Pixel - Processing Data
Once the ground stations receive data from Landsat, there's still a lot of processing to make every pixel usable. Here's an overview of some of that work.

Every Pixel - Recording Data
Recording every pixel as Landsat orbits Earth is a complicated task. Here is an overview of how that data goes from the sensors into the recorder.

Active Breakout of Pu`u `Õ`ō Episode 61G Lava Flow
Video of an active breakout of the Pu‘u ‘Ō‘ō episode 61G lava flow. This breakout is below the pali on the eastern margin of the flow. Pāhoehoe lava is flowing out from the base of an inflated tumulus, and has a characteristic blue tint to its surface crust (compared to the color of solidified lava around it).

New camera shows snowfall on summit
A new HVO webcam provides improved views of Mauna Loa's summit caldera, Moku‘āweoweo, from the northwest rim. This time-lapse sequence shows a full day on Sunday, Dec. 3, starting and ending at midnight. The full moon and sensitive low-light ability of the camera allow good views throughout the nighttime hours.

2017 Nov. Pub. Lecture—Sea Otters: Confessions of a Keystone Carnivore
- Sea otters are perhaps the best-known example of a "keystone predator".
- Sea otter behavior -- in particular diet specialization and limited mobility -- can mediate their effects on ecosystem dynamics.

Majuro Atoll — Topobathymetric Model
This video is of is a three-dimensional (3D) view of the Majuro Atoll, Republic of the Marshall Islands topobathymetric model which consists of topography (land elevation) and bathymetry (water depth). This video shows the importance of high-resolution, detailed topobathymetric models because the highest natural elevation for the Majuro Atoll is only three meters.

Serene Sirens: USGS Sea Cow Science
A USGS video about manatees reveals that while the animals may act like the cows of the sea, they also have more than a bit of the magical siren or mermaid about them. Go for a serene swim.

Channelized Breakout
An impressive channelized breakout appeared on the pali this morning, with lava emerging from the tube and swiftly flowing down the channel towards the base of the pali and coastal plain. Breakouts like these happen occasionally on the pali and are normally short lived.
