Guralp Certimus
Next-generation digital seismic station.
Certimus is an all-in-one portable, digital, broadband triaxial seismometer with state-of-the-art communication capabilities, suitable for direct burial, surface, and subsurface installations. The device has a wide frequency response between 120 s - 100 Hz and remotely configurable long-period corner frequencies. Unlike other broadband instruments, Certimus can operate at any angle up to ± 90°.
Main applications
- Local, regional, and teleseismic monitoring
- Temporary deployments in harsh environments or remote areas
- Rapid deployment for aftershock monitoring
- Microseismic and induced seismic monitoring in the energy sector, carbon storage, etc.
- Geothermal energy production monitoring
- Permanent or rapid temporary installations for monitoring volcanic activity
