Building Borehole Tensor Strain Meters for the Geophysics Earth Strain Community

GTSM Technologies are the suppliers of 3 component borehole tensor strainmeters to UNAVCO for the Plate Boundary Observatory program of Earthscope, the major Research Equipment initiative (2004) of NSF, and to the Central Geological Survey in Taiwan.

This site provides information about the GTSM instruments, including:

· Where the systems are located (USA and Taiwan, Japan , and  Korea )

· General site information where available

· Downloadable data from Active Projects if public

Here are direct download links to currently available data.  The download pages provide a tool for downloading data over a selected date range  in multiple ASCII formats with or without timestamps, Bottle form, and Raw Archive form (as stored in the instrument).  There is also an archive of PBO data which has been processed to strain.

GTSM Technologies has a purpose built software package for  viewing and processing of strain data and associated variables.  WinXQP merges and locally archives raw data files using original field file structures. It generates strain data, allows selective display and export of data sets to third party packages, and simplifies the process of keeping a local archive of data of interest.
