Mountain Rivers Reveal the Earthquake Hazard of Geologic Faults in Silicon Valley

Abstract: The 1989, Mw = 6.9 Loma Prieta earthquake resulted in tens of lives lost and cost California almost 3% of its gross domestic product. Despite widespread damage, the earthquake did not clearly rupture the surface, challenging the identification and characterization of these hidden hazards. Here, we show that they can be illuminated by inverting fluvial topography for slip‐and moment accrual‐rates—fundamental components in earthquake hazard assessments—along relief‐generating geologic faults. We applied this tec… Show more

“…With these boundary conditions, tribemx uses Green's functions (Meade, 2007) to calculate, firstly, the slip vector, with its corresponding strike and dip slip components, at the centroid of each triangular element (e.g., Aron et al, 2022). Secondly, a displacement vector and its horizontal and vertical components on a regular 10 km grid on the Earth's surface.…”

“…We used the 8400 m grid as the final output and average the results of the seismic and interseismic model runs. The Green's functions are used to calculate vertical displacement as a percentage of the total convergence rate (e.g., Aron et al, 2022). Using two control points on the Earth's surface we scaled these dimensionless rock uplift values, x: Xnorm = x -rmin/ rmax -rmin (tmax -tmin)+tmin where rmin and rmax are understood to be the minimum and maximum modelled values of x, and tmin and tmax are minimum and maximum values of xnorm.…”
