Routine, Specialised and Engineering Seismology Services

Routine Seismological Processing and Interpretation Services

To assist mine rock engineering and geotechnical engineers in managing the large amounts of seismic data recorded by the seismic system, ISS International offers routine virtual seismic services. Using our custom-made data transfer technology, seismic data recorded at a mine anywhere in the world can be transferred to ISSI, processed and be back on the mine database within a few minutes.

Processing is carried out according to ISO 9001 procedures and quality controlled by expert mine seismologists. The extensive use of in-house custom software for data manipulation has allowed cost-effective analysis and reporting. Reporting can be as often as several times per day to once per month.

The services team at ISSI has over 60 man-years of experience, and currently analyses and reports on over a hundred working areas for mines in Australasia, Europe, South America and Southern Africa.

Specialised Seismological Services

ISS International offers special seismological analyses for large and/or unusual seismic events, using a multi-disciplinary team of professional engineers and scientists. Analysis specialities include seismic dynamic modelling, statistics, forensic seismology, anatomy of waveforms, numerical stress modelling and quantification of seismic hazard. Such occasional projects are undertaken jointly with the mine geotechnical engineers and focus on the answers to specific questions raised by mine management.

Engineering Seismology

The following services pertaining to measurement and characterisation of ground motion and structure vibration are performed for Engineering Seismology:

• Measurement of ambient noise levels
• Measurement of strong ground motions
• Estimation of site effects associated with surface openings
• Estimation of strong ground motion (e.g. peak ground velocity and acceleration) and the associated frequency of a given site, on the basis of weak excitation.
• Response spectra from the linear and non-linear behaviour of engineering structures
• Modal identification for engineering structures
• Seismic hazard estimation
