Rising Temperature and Decreasing Snow Cover Increase Soil Breakdown
With climate change and rising temperatures, soil freeze-thaw – which is in turn causing soil breakdown – may counterintuitively increase in the hillslopes where snow cover is decreasing.

The State of Stress in the Nankai Subduction Zone
The Nankai subduction zone, in southern Japan, has hosted several large magnitude 8+ earthquakes during the last three hundred years. But, how stressed is it right now?

Cyclic Opening of Deep Fractures Regulates Plate Boundary Slip
Seismic anisotropy changes through time suggest that cyclical opening of fluid-filled fractures is synchronized with subduction zone slow slip events.

Landslides in Art Part 35 – Landslide in Front of the Hodogaya Tunnel on the Tōkaidō (1924) by Oda Kanchō
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. It is over three years since I last posted in my series on Landslides in Art – an unintended gap. For those who are interested, previous editions can be found on the […]

Plate Boundaries May Experience Higher Temperature and Stress Than We Thought
Surface heat flux data shed light on conditions deep below Earth’s surface, at a tectonic plate interface where major earthquakes initiate.
