Project Grant 2439442

This federal Project Grant award from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) provides $349,455 to the University of Washington to investigate seafloor spreading and volcanic activity along the Endeavour segment of the Juan de Fuca Ridge. The project will deploy additional seismometers to enhance an existing cabled observatory network, with the goal of better understanding the precursory earthquakes and processes that trigger seafloor spreading and volcanic eruptions in this region. Key research objectives include determining whether diking events are driven by extensional stresses or magmatic pressures, detecting evidence of aseismic strain or ridge extension, and examining the links between seismicity, hydrothermal activity, and the permeability of the seafloor. The project will also train undergraduate and graduate students in seagoing research and seismic data analysis techniques. The award period runs from April 1, 2025 to March 31, 2029.
