Towards the Usage of Quarry Blasts as an Active Seismic Source for Subsurface Characterization and Imaging
New paper in Geophysical Journal International from ERL/EAPS Principal Research Scientist Nori Nakata, former ERL/EAPS postdoc Hongrui Qiu, and collaborators: Towards the Usage of Quarry Blasts as an Active Seismic Source for Subsurface Characterization and Imaging https://academic.oup.com/gji/advance-article/doi/10.1093/gji/ggad391/7289239 “Active or man-made seismic sources are often used to delineate subsurface geologic structures via seismic imaging techniques. Although…

Searching for partial ruptures in Parkfield
New paper on EOS Archive from ERL/EAPS Prof. Camilla Cattania and collaborators: Searching for partial ruptures in Parkfield “Repeating earthquakes repeatedly rupture the same fault asperities, which are likely loaded to failure by surrounding aseismic slip. However, repeaters occur less often than would be expected if these earthquakes accommodate all of the long-term slip on…

Virtual Hyperspectral Images Using Symmetric Autoencoders
New paper on Arvix by ERL Director Laurent Demanet and collaborators including former ERL postdoc Dr. Pawan Bharadwaj: Virtual Hyperspectral Images Using Symmetric Autoencoders Archisman Bhattacharjee, Pawan Bharadwaj, Laurent Demanet Abstract: Spectral data acquired through remote sensing are invaluable for environmental and resource studies. However, these datasets are often marred by nuisance phenomena such as…
