Martian Meteorite Points to Ancient Hydrothermal Activity
22 November 2024 @ 9:07 pm
The Red Planet had water—in the form of a hydrothermal system—4.45 billion years ago, new analyses of a Martian meteorite suggest.Characteristics of Moist Layers over the Tropical Atlantic
22 November 2024 @ 2:00 pm
In a new study, characteristics of elevated moist layers, their seasonality, spatial distribution, structure, and the coupling of mid-tropospheric circulation and convection are examined over the tropical Atlantic.Why Wildfires Started by Humans, Cars and Power Lines Can Be More Destructive and Harder to Contain
22 November 2024 @ 1:30 pm
While climate change sets the stage for larger and more intense fires, humans are actively fanning the flames.The mobility of landslides triggered by earthquakes
22 November 2024 @ 7:25 am
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. A key determinant of the ability of a landslide to cause loss is its mobility. A more mobile landslide has greater potential capacity to impact humans and their assets, and faster movement […]New Insight into Inland Water Carbon Dioxide Emissions
21 November 2024 @ 2:15 pm
A process-based modeling technique reveals surprising information about carbon emissions from rivers, lakes, and reservoirs across the contiguous United States.New Rules for Catastrophic River Avulsion
21 November 2024 @ 2:14 pm
Scientists thought two factors influencing river avulsion were unrelated, but new research suggests they may be working in tandem. The findings could help predict new river pathways and improve disaster preparedness.La corriente de Florida podría estar desacelerándose, pero no por mucho
21 November 2024 @ 2:11 pm
Una corrección necesaria a un conjunto de datos ampliamente utilizados redujo las estimaciones de los científicos de cómo se ha debilitado la circulación oceánica.The Explosive Origins of Titan’s Rampart Craters
21 November 2024 @ 2:00 pm
In a new study, volcanic explosions are explored and modeled to understand the possible origins of rampart craters on Titan and determine whether their formation can source atmospheric methane.The 30 November 2022 Maratea rockfall in southern Italy
21 November 2024 @ 7:32 am
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. On 30 November 2022, the Maratea rockfall occurred on the slopes below Castrocucco castle in southern Italy. This landslide is the subject of an interesting paper (Santo and Massaro 2024) that has […]Compositional Anomalies Complicate Our Model of Mantle Convection
20 November 2024 @ 2:00 pm
A new study expands on recent research which suggests that oceanic crust accumulates in the mid-mantle. The new seismological constraints advance our understanding of thermo-chemical planetary evolution.
