Rainfall and Landslides in Northern California
A summary of recent and past landslides and debris flows caused by rainfall in northern California, and links to current shallow landslide monitoring.
When hazard avoidance is not an option: Lessons learned from monitoring the postdisaster Oso landslide, USA
On 22 March 2014, a massive, catastrophic landslide occurred near Oso, Washington, USA, sweeping more than 1 km across the adjacent valley flats and killing 43 people. For the following 5 weeks, hundreds of workers engaged in an exhaustive search, rescue, and recovery effort directly in the landslide runout path. These workers could not avoid the...

Progress and lessons learned from responses to landslide disasters
Landslides have the incredible power to transform landscapes and also, tragically, to cause disastrous societal impacts. Whereas the mechanics and effects of many landslide disasters have been analyzed in detail, the means by which landslide experts respond to these events has garnered much less attention. Herein, we evaluate nine landslide...
Collins, Brian D.; Reid, Mark E.; Coe, Jeffrey A.; Kean, Jason W.; Baum, Rex L.; Jibson, Randall W.; Godt, Jonathan W.; Slaughter, Stephen; Stock, Greg M. Remote thermal detection of exfoliation sheet deformation
A growing body of research indicates that rock slope failures, particularly from exfoliating cliffs, are promoted by rock deformations induced by daily temperature cycles. Although previous research has described how these deformations occur, full three-dimensional monitoring of both the deformations and the associated temperature changes has not...
Guerin, Antoine; Jaboyedoff, Michel; Collins, Brian D.; Stock, Greg M.; Derron, Marc-Henri; Abellan, Antonio; Matasci, Battista Linking mesoscale meteorology with extreme landscape response: Effects of narrow cold frontal rainbands (NCFR)
Landscapes evolve in response to prolonged and/or intense precipitation resulting from atmospheric processes at various spatial and temporal scales. Whereas synoptic (large‐scale) features (e.g., atmospheric rivers and hurricanes) govern regional‐scale hydrologic hazards such as widespread flooding, mesoscale features such as thunderstorms or...
Collins, Brian D.; Oakley, N. S.; Perkins, Jonathan P; East, Amy E.; Corbett, Skye C.; Hatchett, Benjamin J. A new data set of granitic rock strength values from Yosemite Valley, California: Applications to rock fall assessment
To explore connections between rock strength and rock falls, we undertook a comprehensive rock mechanics testing program for six granitic rock types in Yosemite Valley (California, USA) where rock falls are a common geomorphic and sometimes hazardous process. We collected samples from boulders located at the base of cliffs, with the inherent...

Rock strength properties of granitic rocks in Yosemite Valley, Yosemite National Park, California
Yosemite National Park, located in the central part of California’s Sierra Nevada mountains, is a glacially carved landscape filled with iconic rock formations such as Cathedral Peak, El Capitan, and Half Dome. Igneous rocks, consisting primarily of variations of granite, granodiorite, and tonalite, make up the majority of the bedrock geology and...
Collins, Brian D.; Sandrone, Federica; Gastaldo, Laurent; Stock, Greg M.; Jaboyedoff, Michel Quantifying 40 years of rockfall activity in Yosemite Valley with historical Structure-from-Motion photogrammetry and terrestrial laser scanning
Rockfalls and rockslides are often dominant geomorphic processes in steep bedrock landscapes, but documenting their occurrence can be challenging, requiring frequent monitoring and well resolved spatial data. Repeat application of remote sensing methods such as Terrestrial Laser Scanning (TLS) and Structure-from-Motion (SfM) photogrammetry can...
Guerin, Antoine; Stock, Greg M.; Radue, Mariah J.; Jaboyedoff, Michel; Collins, Brian D.; Matasci, Battista; Avdievitch, Nikita; Derron, Marc-Henri Assessing the feasibility of satellite-based thresholds for hydrologically driven landsliding
Elevated soil moisture and heavy precipitation contribute to landslides worldwide. These environmental variables are now being resolved with satellites at spatiotemporal scales that could offer new perspectives on the development of landslide warning systems. However, the application of these data to hydro-meteorological thresholds (which account...
Thomas, Matthew A.; Collins, Brian D.; Mirus, Benjamin B. Detection of rock bridges by infrared thermal imaging and modeling
Characterization of rock discontinuities and rock bridges is required to define stability conditions of fractured rock masses in both natural and engineered environments. Although remote sensing methods for mapping discontinuities have improved in recent years, remote detection of intact rock bridges on cliff faces remains challenging, with their...
Guerin, Antoine; Jaboyefoff, Michel; Collins, Brian D.; Derron, Marc-Henri; Stock, Greg M.; Matasci, Battista; Boesiger, Martin; Lefeuvre, Caroline; Podladchikov, Yury Y. Enhanced landslide mobility by basal liquefaction: the 2014 SR530 (Oso), Washington landslide
Landslide mobility can vastly amplify the consequences of slope failure. As a compelling example, the March 22, 2014 landslide near Oso, Washington (USA) was particularly devastating, traveling across a 1-km+ wide river valley, killing 43 people, destroying dozens of homes, and temporarily closing a well-traveled highway. To resolve causes for...
Collins, Brian D.; Reid, Mark E. Relaxation response of critically stressed macroscale surficial rock sheets
Rock environments both underground and on Earth’s surface show indications of energetic macroscale fracture. In tunnels and excavations, these manifest as rockbursts—energetic explosions of rock that can damage engineering projects, and may pose ongoing financial and safety risk as rock stresses adjust during post-failure relaxation. In natural...

Terrestrial lidar data of the February 14, 2019 Sausalito Boulevard Landslide, Sausalito, California
On February 14, 2019, just before 2:56 am local time (Pacific Standard Time), a landslide initiated from the hillslopes above the Hurricane Gulch section of the City of Sausalito, Marin County, California. The landslide, specifically classified as a debris flow, overran a road (Sausalito Boulevard) immediately below the landslide source area and...

Why Do Giant Rocks Suddenly Fall From Cliffs?
"In Yosemite Valley, rockfalls can happen every four to five days, where boulders that can be larger than your average car or apartment building thunder down steep mountainsides." - Seeker
