Nanometrics industry-leading Trillium 120-class posthole seismometer in
a slim form-factor of just 104 mm, ideal for use in existing narrow, cased
boreholes.
The first modern broadband seismometer to be based on a Galperin configuration was the Streckeisen STS-2, an observatory-grade vault instrument introduced in 1990. Nanometrics introduced a symmetric triaxial seismometer with a 240 s lower corner period, the Trillium 240, in 2004. There are now a…
Nanometrics’ industry-leading portfolio of Trillium seismometers includes a posthole variant that is revolutionizing the way seismologists deploy instruments and collect seismic data.
Nanometrics industry leading portfolio of Trillium 120 broadband seismometers are available in both posthole and traditional borehole with holelock packages.
Challenge
The collapse of the Napoleonville Salt Dome in August 2012 produced a large sinkhole located 1300 feet from the community of Bayou Corne in Assumption Parish, Louisiana.
The Nanometrics Trillium 120 Posthole (Trillium Posthole) seismometer is designed for subsurface installation to optimize seismic performance while minimizing the cost and logistics of site setup.
A new broadband seismograph network for passive seismic imaging of earth structures has been installed in the Yukon using a new Posthole installation method that is now yielding excellent results.
Network design for induced seismicity monitoring is of critical importance. In many applications, networks for induced seismicity have specific criteria with respect to minimum detection magnitudes and the accuracy of event locations.
The Trillium 360 is the world’s highest-performing broadband seismometer. Available in Vault, Posthole or Borehole form factors, the 360 gives you full-bandwidth coverage for monitoring global and local seismicity with a single instrument.
