Geodetic Data

Currently to make geodetic observations the USGS uses the Global Positioning System (GPS) and also other techniques. (creepmeters, tiltmeters, strainmeters, magnetometers, pore pressure monitors).

Earth Structure and Site Response

Ground Motion and Site Conditions

The data obtained from active source studies are archived at IRIS and/or at the National Geophysical Data Center. USGS also provides access to certain data sets.

Hazard Assessment Data and Models

Faults and Folds
