FEMA Mitigation Best Practices: GPS System Measures Earthquake Potential   [open pdf - 31KB]

Alternate Title: Measuring Earthquake Potential with GPS

"The FEMA Best Practices Portfolio consists of mitigation stories submitted by individuals and communities that describe measures they have taken to reduce the loss of life and property from disasters. These Best Practices are meant to provide ideas and concepts about reducing losses and to encourage others to evaluate their own risk and consider mitigation as a long-term solution to reducing that risk." [...] "The Southern California Integrated GPS Network (SCIGN), a new type of ground motion monitoring network. Using SCIGN data to measure deformation of the Earth's crust, which can occur as movement on a fault or as slow distortion of the ground, scientists can determine how strain builds up slowly over time before being released suddenly during an earthquake. These new GPS measurements contribute to improving the region's earthquake hazards assessments that help motivate people to prepare for earthquakes." This and other individual FEMA Best Practices documents are also combined in "Mitigation Best Practices: Public and Private Sector Best Practice Stories for All Activity/Project Types in All States and Territories Relating to All Hazards [August 10, 2011]," which can be accessed at the following link: [https://www.hsdl.org/?abstract&did=683132]
