Landslides in granular soils can be highly hazardous when exhibiting flow‐like behavior. The extensive mass wasting associated with the 2008 Mw = 7.9 Wenchuan earthquake (China) left several cubic kilometers of loose granular material deposited along steep slopes and in low‐order channels. Rainfall‐triggered remobilization of these deposits evolved often into catastrophic flow‐like landslides. Ten years after the earthquake, most of the deposits are still in place but landslide rates have… 
Enhanced Rainfall‐Induced Shallow Landslide Activity Following Seismic Disturbance—From Triggering to Healing
Evidence suggests that following earthquakes, landslide activity, and susceptibility remain elevated for months to years after cessation of shaking. In landslides constrained within the soil mantle,
Earthquake‐Induced Chains of Geologic Hazards: Patterns, Mechanisms, and Impacts
Large earthquakes initiate chains of surface processes that last much longer than the brief moments of strong shaking. Most moderate‐ and large‐magnitude earthquakes trigger landslides, ranging from
Controls on Post‐Seismic Landslide Behavior in Brittle Rocks
Earthquakes trigger widespread landsliding in tectonically active landscapes. The effects of strong ground shaking on hillslope stability persist into the post‐seismic stage; rates of landsliding
Rapidly Evolving Controls of Landslides After a Strong Earthquake and Implications for Hazard Assessments
Strong earthquakes, especially on mountain slopes, can generate large amounts of unconsolidated deposits, prone to remobilization by aftershocks and rainstorms. Assessing the hazard they pose and
Triggering and propagation of exogenous sediment pulses in mountain channels: insights from flume experiments with seismic monitoring
Abstract. In the upper part of mountain river catchments, large amounts of loose debris produced by mass-wasting processes can accumulate at the base of slopes and cliffs. Sudden destabilizations of
Two-dimensional finite element modeling of seepage-erosion coupled process within unsaturated soil slopes
Fines migration along with rainfall infiltration is a possible cause of failures of slopes composed of loose deposits. To investigate the intrinsic mechanisms, a rigid mathematical model which can
Acoustic Emissions and Microseismicity in Granular Slopes Prior to Failure and Flow‐Like Motion: The Potential for Early Warning
Rain‐triggered landslides in loosely packed granular deposits are highly hazardous because of their sudden failure, flow‐like motion, and high mobility. Predicting their initiation and establishing
Spatio-temporal evolution of mass wasting after the 2008 Mw 7.9 Wenchuan earthquake revealed by a detailed multi-temporal inventory
Strong earthquakes in mountainous areas can trigger a large number of landslides that generate deposits of loose and unconsolidated debris across the landscape. These deposits can be easily


Debris-flow mobilization from landslides
▪ Abstract Field observations, laboratory experiments, and theoretical analyses indicate that landslides mobilize to form debris flows by three processes: (a) widespread Coulomb failure within a
Evaluation of landslide triggering mechanisms in model fill slopes
Hong Kong is particularly susceptible to landslide risk due to the steep natural topography and prolonged periods of high intensity rainfall. Compounding the risk of slope failure is the existence of
Transient changes of landslide rates after earthquakes
Earthquakes impart an impressive force on epicentral landscapes, with immediate catastrophic hillslope response. However, their legacy on geomorphic process rates remains poorly constrained. We have
Process dependence of grain size distributions in rock avalanche deposits
Rock avalanches are a form of hazardous long-runout landslide and leave fragmented deposits of complex sedimentology that, if studied in detail, can provide insight into their emplacement processes.
The control of earthquake sequences on hillslope stability
Earthquakes trigger landslides in mountainous regions. Recent research suggests that the stability of hillslopes during and after a large earthquake is influenced by legacy effects of previous
Relationships among three repeated large-scale debris flows at Pubugou Ravine in the Wenchuan earthquake zone
The 12 May 2008 Wenchuan earthquake in China triggered numerous landslides. Loose landslide materials can easily evolve into deadly debris flows during wet seasons. During the period from 2008 to
