Application of microtremor measurements to earthquake engineering
Two previous papers published in this Bulletin (Refs 1, 2) described the methods developed at the University of Auckland, School of Engineering for recording and analysing microtremors. In this paper, the applications of microtremor measurements to earthquake resistant design of structures are critically examined. Specific applications are discussed and compared with results obtained by the authors. Finally, it is shown that, using computer techniques, it is possible to simulate ground motions which have the characteristics of recorded microtremor motions.
