Instrument & Data Quality Research
USGS scientists are conducting research in a number of areas to help improve instrumentation and data quality. These improvements ultimately result in more precisely-located earthquakes and better science.
An increase in earthquakes in the central and eastern US prompts two important questions: Are they natural, or man-made? What should be done in the future as we address the causes and consequences of these events to reduce associated risks?
The Effects of Basins, Topography, and Fault Zones on Seismic Waves
These studies use basins, ridges, and fault zones in the San Francisco Bay area as a laboratory to explore in greater detail what is happening as seismic waves propagate through them.
- Central US Seismic Velocity Model
- East Bay Seismic Experiment
- The Effects of Basins, Topography, and Fault Zones on Seismic Waves: San Francisco Bay Area Portable Seismograph Deployments
- The Salton Seismic Imaging Project
- Site Response in the Northern San Francisco Bay Area, California
The USGS invites research proposals that will assist in achieving the goals of the National Earthquake Hazards Reduction Program (NERHP).
