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).

• Crustal Deformation Data

Earth Structure and Site Response

• Vs30 Data
• Cone Penetration Testing (CPT) Data

Ground Motion and Site Conditions

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

• Landslide hazard maps and data:
  • U.S. Landslide Inventory
  • Coseismic Landslides Data

Hazard Assessment Data and Models

• International Hazard Map Data
