The Lawrence Livermore Laboratory seismic net was upgraded by installing two horizontal seismometers at each of the four LLL stations. These seismometers record radial and transverse ground motion from underground nuclear explosions at the Nevada Test Site and complement the vertical components which were installed several years ago. Each station now monitors three orthogonal components of ground velocity over a broad frequency band.
