Geologic model for abyssal seismoturbidite generation along the Cascadia Subduction Zone. (A) With each earthquake cycle, slope failures occur on the oversteepened limbs of thrust folds in the accretionary wedge, resulting in proximal MTDs and turbidity flows that spread out across the abyssal plain.

Enlargements of 1-m AUV bathymetry overlain on 30-m bathymetry grid for the study area along the Cascadia Subduction Zone. (A) The AUV bathymetry data reveal a 10m high failure scarp that extends for 4km along the seaward face of the frontal thrust fold. Secondary reverse faults observed in the chirp subbottom data are expressed at the seafloor with ~3m offsets.

USGS Coastal Storm Modeling System (CoSMoS) flood hazard maps for coastal adaptation planning across California are now available state-wide.

Time-series from the entire 132-d deployment. a Wind velocity (black vectors, left axis), and barometric pressure (orange line, right axis) measured by the Ponce buoy; the timing of two major tropical cyclones (TC), Irma and Maria, are labeled and correspond to the sharp dips in barometric pressure.
