Lydia M Staisch, Ph.D.

Lydia is a Research Geologist with the GMEG Science Center, working on structural geology, tectonic geomorphology, geologic mapping, and seismic hazards in the Pacific Northwest. She graduated from the University of Michigan in 2014, where she focused on the deformation history of the northern Tibetan Plateau and coseismic landslide hazards in the Himalayas.

Afterwards, Lydia was a Mendenhall Postdoctoral Fellow with Brian Sherrod at the Earthquake Science Center. Her general research interests are in continental deformation and landscape evolution. She tends to employ a multi-faceted approach in her research, including field work, structural-stratigraphic analysis, geochemical analysis, geodynamic modeling, remote sensing and geodesy.

Subduction zone geometry modulates the megathrust earthquake cycle: Magnitude, recurrence, and variability

Megathrust geometric properties exhibit some of the strongest correlations with maximum earthquake magnitude in global surveys of large subduction zone earthquakes, but the mechanisms through which fault geometry influences subduction earthquake cycle dynamics remain unresolved.

Crustal structure and quaternary acceleration of deformation rates in central Washington revealed by stream profile inversion, potential field geophysics, and structural geology of the Yakima folds

Post‐Miocene tectonic uplift along fault‐cored anticlines within central Washington produced the Yakima Fold Province, a region of active NNE‐SSW shortening in the Cascadian backarc. The relative timing and rate of deformation along individual structures is coarsely defined yet imperative for seismic hazard assessment. In this work, we use geomorphic and geophysical mapping, stream profile inversi

Miocene−Pleistocene deformation of the Saddle Mountains: Implications for seismic hazard in central Washington, USA

The Yakima fold province, located in the backarc of the Cascadia subduction zone, is a region of active strain accumulation and deformation distributed across a series of fault-cored folds. The geodetic network in central Washington has been used to interpret large-scale N-S shortening and westward-increasing strain; however, geodetic data are unable to resolve shortening rates across individual s

Cascadia subduction zone database: compilation of published datasets relevant to Cascadia subduction zone earthquake hazards and tectonics

As part of the USGS Powell Center working group on Cascadia earthquake hazards, we compile and host several available geologic, paleoseismic, geophysical, and instrumental datasets along the Cascadia subduction zone. The ArcGIS online map and downloadable map package include both raster images and shapefiles. In this Story Map, we outline the features and datasets compiled.
