Embankment vibration characteristics using ground motion records and ambient noise measurements, Briones Dam, California Open
Investigating the seismic response of earth embankment dams is crucial for assessing the safety of existing dams and guiding new design procedures. The dam fundamental frequency (f0) is a critical parameter in the dynamic response of dams …
Fully remote assessment of rockfall incidents based on crowdsourced imagery Open
This paper presents a fully remote approach for the assessment of rockfall incidents that is based on leveraging data that become available online with the goal to develop three dimensional (3D) models, document in detail the rockfall traj…
Regional Back‐Analysis of Earthquake Triggered Landslide Inventories: A 2D Method for Estimating Rock Strength From Remote Sensing Data Open
Landslides occur where the stresses below the surface exceed the shear strength of the material. Landslide inventories thus offer opportunities to investigate patterns in subsurface strength provided that the stress conditions at failure c…

Quantifying surface process dynamics during extreme events from storm characteristics and landslide inventories Open
Extreme precipitation events drive landsliding in many regions across the globe and are an important part of the erosional cycle and related hazards. The intensity and frequency of extreme events are likely increasing due to rising global …

Transformation, Transport, and Storage of Major Elements in Municipal Solid Waste Disposal Sites Open
The predominant management approach for municipal solid waste (MSW) remains disposal, given significant increases in generation and disposal rates of MSW in recent decades. In addition to the well-documented carbon emissions from disposal …

The 2021 Melamchi Flood: A massive erosional cascade in the Himalayan Mountains of central Nepal Open
Large, sediment-laden floods in mountainous terrain can have disastrous consequences and play important roles in landscape evolution. These events often unfold as a series of interconnected processes, but understanding of such “hazard casc…

Landslides Triggered by Medicane Ianos in Greece, September 2020: Rapid Satellite Mapping and Field Survey Open
Medicanes, a type of strong hurricanes/cyclones occurring in the Mediterranean, can be the source of major geohazard events in Mediterranean coastal and inland areas. Medicane Ianos that hit Greece during 17–19 September 2020 caused widesp…
Realities of bridge resilience in Small Island Developing States Open
Small Island Developing States (SIDS) are acknowledged as particularly vulnerable to extreme climate events; however, the realities for transport infrastructure and bridges are still poorly studied. Assessing bridges in this context can be…

Near‐Surface Geomechanical Properties and Weathering Characteristics Across a Tectonic and Climatic Gradient in the Central Nepal Himalaya Open
Shallow bedrock strength controls both landslide hazard and the rate and form of erosion, yet regional patterns in near‐surface mechanical properties are rarely known quantitatively due to the challenge in collecting in situ measurements. …
Coupled process modeling for energy generation from municipal solid waste degradation: Laboratory-scale and field-scale simulations Open
Modern regulated landfills are designed to protect the environment by containing and isolating municipal solid waste (MSW) from the environment. Instead of treating MSW as a hazard to be contained, next generation landfills, here termed Su…
Coseismic deformation of the ground during large-slip strike-slip ruptures: Finite evolution of “mole tracks” Open
To evaluate ground deformation resulting from large (~10 m) coseismic strike-slip displacements, we focus on deformation of the Kekerengu fault during the November 2016 Mw 7.8 Kaikōura earthquake in New Zealand. Combining post-earthquake f…
Profiles of Near‐Surface Rock Mass Strength Across Gradients in Burial, Erosion, and Time Open
Rock mass strength is recognized as an important control on landscape morphology and evolution. However, the controls on rock strength in mountainous topography remain poorly characterized, in part because strength remains challenging to q…
Waste-composition-dependent ‘HBM’ model parameters based on degradation experiments Open
Municipal solid waste (MSW) is biodegradable in landfills under anaerobic conditions. The evolution of the hydro-biochemical-mechanical (HBM) processes during degradation is investigated first through experiments and subsequently through m…
Closure to “Ground Vibration Measurements near Impact Pile Driving” by Athina Grizi, Adda Athanasopoulos-Zekkos, and Richard D. Woods Open
The authors would like to thank the discusser for his interest in this work.The discusser states that there are no connections of the obtained results with the problem of dynamic settlement or any investigations of dynamic settlement in th…
UAV-based mapping, back analysis and trajectory modeling of a coseismic rockfall in Lefkada island, Greece Open
We present field evidence and a kinematic study of a rock block mobilized in the Ponti area by a Mw = 6.5 earthquake near the island of Lefkada on 17 November 2015. A detailed survey was conducted using an unmanned aerial vehicle (UAV) wit…
Strong variation in weathering of layered rock maintains hillslope‐scale strength under high precipitation Open
The evolution of volcanic landscapes and their landslide potential are both dependent upon the weathering of layered volcanic rock sequences. We characterize critical zone structure using shallow seismic V p and V s profiles and vertical e…
Earthquake science in resilient societies Open
Earthquake science is critical in reducing vulnerability to a broad range of seismic hazards. Evidence‐based studies drawing from several branches of the Earth sciences and engineering can effectively mitigate losses experienced in earthqu…
