• 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…
  • 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.
