- North America ; San Andreas Fault
- Project Type: Research
DESCRIPTION: Use biomarker thermal maturity analysis to determine whether earthquake temperature rise has occurred in material from the San Andreas Fault core; nvestigate and rule out other sources of heating/alteration that may cause biomarker reaction, such as hydrothermal fluids and migrated petroleum.; Estimate the temperature rise if a coseismic heating signal is observed.; Model earthquake slip along the San Andreas Fault to determine the properties of the earthquake that could generate any observed heating signal (e.g., location within the fault, stress, displacement).
