FPM Geophysical & UXO Services is one of the leading geophysical services firms in North America. With 8 regional offices and our main office in Oak Ridge Tennessee, we are strategically positioned to provide service to our customers throughout the United States and overseas.
FPM's highly-experienced staff of geophysicists, engineers and technicians has worldwide project experience collecting, reporting and managing geophysical data from
environmental, engineering, water
resource , and UXO geophysical surveys for our commercial and government clients. Using a broad spectrum of surface and borehole geophysical technologies, we provide high-resolution geophysical imaging services for nearly any project type. Innovation and creativity, combined with a strong work ethic and an understanding of our clients needs and project constraints, are the qualities that make FPM the best choice.
Our personnel collect and analyze a variety of geophysical data types, but are also well-rounded in geology, groundwater hydrology, and geographic information system (GIS) applications. Some of the more common geophysical surveys we perform include:
Magnetic , Gravity, and Spontaneous Potential (SP)
Time- and Frequency-Domain Electromagnetic (EM)
Ground Penetrating Radar (GPR)
Electrical Resistivity and Induced Polarization (IP)
FPM routinely collects global positioning system (GPS) or total station land survey data during fieldwork to provide precise geophysical data positioning. We understand that our customers often need more than data outputs and interpretive maps. Our GIS specialists can prepare maps and cross-sections integrating existing site information and land survey data together with the geophysical information. In short, we are innovative and qualified to match your technical needs, and have the dedication to ensure that your project is successful.
Understanding the limitations of any geophysical method is as important as knowing the capabilities of that particular technique. We are aware of those limitations and will assist you in determining the most suitable geophysical approach for your project.
The observation reveals new relationships between earthquakes and landslides
improve our understanding of earthquakes precise knowledge of friction properties along active faults and the processes through which they release the accumulated stresses. Understanding GPS; How to Use Data and Accountability
If earthquakes are the most obvious mode of relaxation,development of GPS network in subduction zones, the causes and role in the earthquake cycle have yet to understand. Until now, aseismic transient shifts observed were of two types: the episodes of slow earthquakes during the loading phase faults and glides immediately following the large and moderate earthquakes .
The first are introduced spontaneously, without clear trigger process, they are characterized by a gradual acceleration and deceleration slip accompanied by seismic tremor or earthquake swarm, Adventures in Learning How to Use a GPS
contributing significantly to the stress relief. The second sliding type aseismic is triggered by an earthquake and has a decrease in the sliding speed over time. The size of the shift depends on the size of the earthquake.

SCREEN SIZE:
The larger your GPS screen the more money it will cost you. You can save money by getting a smaller screen, but also keep in mind that a large screen will make it simple to control all the functions and give you a more detailed images to keep you ready for the next turn. The average size for cell phones is five-inches screen, most screens are color touch screen. If you want to fit the system to your windscreen, then go for a compact model.
