The McSIES-MT NEO is a data acquisition instrument for microtremor array measurement and vibration monitoring. It is an all-in-one device in which high-performance accelerometer containing 1 component or 3 components, a precise global positioning system (GPS) and a battery are incorporated. It can be used for microtremor measurement for obtaining the natural frequency, vibration property of the ground, and vibration property of a structural object.

Microtremor array survey can be performed by assembling a triangular array using 4 or 7 units. The precise GPS in each instrument makes it possible to synchronize all recordings easily. In addition, software ''SeisImager / MT NEO'' is available for analyzing phase velocity to produce the 1D S-wave velocity structure of the ground. Optional wireless LAN communication function is also available.



  • The all-in-one structure enables measurements without a cable
  • Operational menu is simply displayed on its LCD screen
  • Data can be easily transferred from its SD memory card to a PC
  • Temporal synchronous measurements between multiple devices, the correction of a clock in the device, and the acquisition of positional information are enabled by its GPS
  • A special program, SeisImager / MT NEO, is available for the analysis of its data
  • With an optional wireless communication module, various settings of devices and confirmation of data is possible via wireless communications.
