A look at the blind Kumamoto experiment: combining active and passive seismic observations to avoid Rayleigh-wave mode misidentification

Earth, Planets and Space, 2023
We present our pathway through participation in the blind Kumamoto exercise, particularly the Step 1 of site characterization. The combination of passive and active seismic imaging techniques is used to image the velocity profile beneath the KUMA site ...

New progress on the onshore-offshore seismic survey in East China Continental Margin

Solid Earth Sciences, 2019
The East China Continental Margin (ECCM) is an exemplified natural laboratory not only for studying the origin and evolution of trench-arc-basin system, but also for investigating the deformation mechanism within continent and its margins.

Ambient Seismic Noise and Microseismicity Monitoring of a Prone-To-Fall Quartzite Tower (Ormea, NW Italy)

Remote Sensing, 2021
Remote sensing techniques are leading methodologies for landslide characterization and monitoring. However, they may be limited in highly vegetated areas and do not allow for continuously tracking the evolution to failure in an early warning perspective.
