No significant changes at Kīlauea's summit water lakeAn HVO geologist collects GPS data on the western rim of Kīlauea's summit caldera. The geologist is standing upon a thick sequence of tephra deposits formed during explosive eruptions at Kīlauea's summit between about 1500 CE and the early 19th century.

Eyes on Earth Episode 29 – Tracking Landscape Change with LCMAP
Eyes on Earth Episode 29 – Tracking Landscape Change with LCMAPThe U.S. Geological Survey took a bold step toward documenting change across the landscape with the launch of the first Landsat satellite in 1972. Since then, it’s collected nearly five decades of imagery. But it takes more than just imagery to understand change. It takes time, effort—and serious computing horsepower.

Image of the Week - Virtual Road Trip with Landsat
Image of the Week - Virtual Road Trip with LandsatSummer vacation plans changed for many in 2020. Whatever your plans, Landsat can take you on a virtual road trip. Landsat 8, in its sun-synchronous polar orbit, views every national park in the U.S. every 16 days and gathers more photographic data than the most ambitious of tourists.

Absaroka Mountains in northeastern Yellowstone National ParkA view into the Absaroka Mountains in northeastern Yellowstone National Park. While the Absarokas of today look a little different due to glacial activity, these are the same mountains that existed over the last 53 million years, well before the arrival of the Yellowstone hot spot.
