We focus on the 6 August 2010 Mount Meager landslide that occurred in Southwest British Columbia, Canada. This 48.5 Mm3 rockslide that rapidly changed into a debris flow was recorded by over 25 broadband seismic stations. We showed that the waveform inversion of the seismic signal making it possible to calculate the time history of the force applied by the landslide to the ground is very robust and stable, even when using only data from a single station. By comparing this force with the… Expand
Estimation of dynamic friction and movement history of large landslides
We performed seismic waveform inversions and numerical landslide simulations of deep-seated landslides in Japan to understand the dynamic evolution of friction of the landslides. By comparing theExpand
Constraining landslide characteristics with Bayesian inversion of field and seismic data
Using a fully nonlinear Bayesian approach based on forward modelling of granular flow, we invert for landslide parameters (volume, release geometry and rheology) from different kinds of observations.Expand
Variation patterns of landslide basal friction revealed from long-period seismic waveform inversion
A catastrophic landslide struck the Xiaoba village in Fuquan, Guizhou, southwestern China at about 8:30 p.m. (Beijing Time, UTC + 8) on August 27, 2014. The landslide and induced impulse water wavesExpand
Analysis of Broadband Seismic Recordings of Landslide Using Empirical Green's Function
The 2010 Mount Meager landslide generated strong seismic waves. We used seismic signals generated by a smaller landslide that occurred within 2 min of the end of the main landslide as the empiricalExpand
Friction weakening in granular flows deduced from seismic records at the Soufrière Hills Volcano, Montserrat
Accurate modeling of rockfalls and pyroclastic flows is still an open issue, partly due to a lack of measurements related to their dynamics. Using seismic data from the Soufriere Hills Volcano,Expand
Complex force history of a calving‐generated glacial earthquake derived from broadband seismic inversion
The force applied to the Earth by the calving of two icebergs at Jakobshavn Isbrae, Greenland, has been quantified. The source force history was recovered by inversion of regional broadbandExpand
Dynamic process analysis of the Baige landslide by the combination of DEM and long-period seismic waves

Characterization of rockfalls from seismic signal: Insights from laboratory experiments
The seismic signals generated by rockfalls can provide information on their dynamics and location. However, the lack of field observations makes it difficult to establish clear relationships betweenExpand
Dynamics of the Askja caldera July 2014 landslide, Iceland, from seismic signal analysis: precursor, motion and aftermath
Abstract. Landslide hazard motivates the need for a deeper understanding of the events that occur before, during, and after catastrophic slope failures. Due to the destructive nature of such events,Expand
