This book presents the results of seismic data analysis and interpretation based on nearly one
million seismic events. This seismicity was induced by the caving process in four copper mines
each located on a different continent. The book not only serves as an interpretation guide it
also illustrates the benefits of evaluating data from different mines:How to establish which
seismic data base is faulty and whyThe formation of a universal seismic response to the caving
processIndisputable evidence that hydro-fracturing improves underground safety This book
invites discussion on more general aspects of research such as:Basic research applied
research and implementationPredicting mine-induced seismic eventsQuantitative versus
qualitative seismologyResearch versus pseudo-researchWhat is genuine research?[In the Parlabora
Mine] Stefan has demonstrated that [the] use of the seismic system was a very practical means
of monitoring the progression of the cave up to and beyond break through into the open pit
above. The seismic system was vital in drawing up the undercutting and seismic protocols and
determining the maximum potential seismic hazard level. Peter Townsend Retired Mine Manager and
ConsultantI consider Stefan the pioneer of using microseismic data to provide understanding of
the mechanism and progress of cave mining. Science has advanced considerably since the use of
less than reliable extensometers to monitor the cave back position and Stefan was leading this
advance. (...)This book provides a lot of useful insight[s] in how we can best understand the
data that we (...) gather and how to change this data into useful information. Neil Hepworth C.

seismology trilogy is (...) a comprehensive tutoring on how to analyse and interpret mine
induced seismicity. This coaching is based on multiple practical examples (...) presented from
the problem to be solved [with] input data tests followed by analysis and interpretation. This
last is presented with many details that explain the whole process. Mahdi Bayuargo ST MAScPT.
