MicroFlow: Domain-Specific Optical Flow for Ground Deformation Estimation in Seismic Events
Juliette Bertrand, Sophie Giffard-Roisin, James Hollingsworth +1
Dense ground displacement measurements are crucial for geological studies but are impractical to collect directly. Traditionally, displacement fields are estimated using patch matc…

A systematic search for tectonic tremor and low-frequency earthquakes in the Atacama segment of the Chilean subduction zone (24S-31S) turns up empty
Jannes Münchmeyer, William B. Frank, Sophie Giffard-Roisin +2
Subduction megathrusts release stress not only seismically through earthquakes, but also through creep and transient slow deformation, called slow slip events (SSEs). Understanding…

Denoising of Geodetic Time Series Using Spatiotemporal Graph Neural Networks: Application to Slow Slip Event Extraction
Giuseppe Costantino, Sophie Giffard-Roisin, Mauro Dalla Mura +1
Geospatial data has been transformative for the monitoring of the Earth, yet, as in the case of (geo)physical monitoring, the measurements can have variable spatial and temporal sa…
