New Map Reveals the Extent of Vegetation in Antarctica
More than 40 square kilometers of vegetation cover Antarctica, including in previously unknown areas. A new map offers fresh insights for conservation amid climate change.
As the River Flows the Colors Sparkle
Diving into the science behind river color and its relationship with flow.
New satellite imagery of the 11 May 2024 tailings failure at Siana in Surigao del Norte, Philippines
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. Just under a month ago, I wrote about the tailings failure at the Siana gold mine in Surigao del Norte, Philippines. Capella Space captured good radar imagery of the site. We now […]
The 22 July 2021 Xiao Dongsuo debris flow on the Tibetan Plateau
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. Debris flows in arid and semi-arid areas are less common than in more humid environments, but they can have devastating consequences. There has been considerably less research into these processes than might […]
New Insights on Atmospheric Waves from the Hunga Volcanic Eruption
High temporal resolution geostationary imagery reveals new details of atmospheric waves generated by the January 2022 Hunga volcanic eruption and provides a chronology of the eruption sequence.
Challenges in Measuring Aerosol Cloud-Mediated Radiative Forcing
Satellites are required for the global measurement of aerosol cloud-mediated radiative forcing, but satellite retrievals of aerosols and cloud properties still have challenges to overcome.
Urban Nature Is Often Plentiful but Inaccessible
A novel research framework deepens understanding of urban nature accessibility and highlights progress toward green space goals.
Iceland’s Recent Eruptions Driven by Tectonic Stress
Magma flow in the magmatic dike near Grindavík was among the fastest recorded. The processes driving that flow could be at play at volcanoes in Hawaii, off the African coast, and anywhere crustal plates split apart.
Monitoring Polar Ice Change in the Twilight Zone
Landsat’s new extended data collection program is mapping Arctic and Antarctic regions year-round, even in polar twilight.
