California's carbon mitigation efforts may be thwarted by climate change itself
climate change carbon mitigation ecosystem
2021/8/3
To meet an ambitious goal of carbon neutrality by 2045, California's policymakers are relying in part on forests and shrublands to remove CO2 from the atmosphere, but researchers warn that future clim...
Cenozoic tectonic rotation of the Mojave Desert, California as indicated by paleomagnetic studies
The mojave desert crustal movement paleomagnetism volcanoes the earth's crust
2014/10/22
Strain distribution across broad plate boundaries is inadequately understood. California's Mojave Desert has been adjacent to Tertiary convergent and transform plate margins and its general geology is...
Boundary Element Method Numerical Modeling: An Approach for Analyzing the Complex Geometry and Evolution of the San Gorgonio Knot, San Andreas Fault, Southern California
Boundary Element Method Numerical Modeling Complex Geometry Evolution of the San Gorgonio Knot San Andreas Fault Southern California
2014/10/22
The San Andreas fault forms the right lateral transform boundary between the North American and Pacific tectonic plates. At various locations along the San Andreas fault the geometry of the fault surf...
The Role of Fluids in Promoting Seismic Activity in Active Spreading Centers of the Salton Trough, California, USA
Crustal Model Magmatic Intrusion Salton Trough Seismic Activity Spreading Centers
2013/3/7
We interpret seismic activity in the active spreading centers of the Salton Trough to indicate 1) a magmatic intrusion in the lower crust beneath the active Brawly, Cerro Prieto, Imperial, Elsinore, a...
