InSAR allows to quantify very accurately the vertical/horizontal displacements through time of local points onto the earth surface. We use InSAR to quantify the subtile subsidence of jetties in coastal areas.
Shocks between grains during coastal transport and water mass compression drive a seismic noise which is recorded by the devices traditionnally dedicated to the survey of earthquake activity. We explore this signature to quantify some relevant coastal informations on sediment transport and wave features to the shoreline.
The analysis of the time-spatial distribution of peculiar patterns within the ambiant noise recorder at seismometers and OBS allows to determine the track of typhoons.
