"Applying alternative and different approaches to seismic hazard assessment is instructive. It \r\nallows learning from the different outcomes of the different approaches. These outcomes may be mutually \r\nreinforcing or diverge, suggest further study and research is needed, or provide new insights into old \r\nproblems. Herein Java island-scale seismic hazard will be considered by applying different probabilistic \r\napproaches to hazard assessment. Results from two distinct methods are provided for Java: 1) primary zoning \r\nusing K-means partitioning of seismicity into spatial clusters (progressed into zones) which are then \r\ndeveloped into seismic hazard maps using Monte Carlo earthquake catalogue simulation, and 2) extreme \r\nvalue analysis applied at a matrix of points throughout a zoneless Java. The latter approach has been used \r\nbefore, the former adopts seismicity partitioning into spatial clusters prior to Monte Carlo modelling and is \r\nnovel. The earthquake catalogue analysed is NEIC (1973-2006). This catalogue is homogenised to the \r\nmoment magnitude scale Mw and Poisson declustering of fore- and after-shocks applied. The completeness \r\nthreshold is around 4.9 Mw . Shallow earthquakes down to 80 km depth contribute most to the hazard and are \r\npartitioned into 1 to K trial clusters of seismicity by minimising the total within cluster distance from seed \r\ncentroids. Repeated trials produce an optimum partition. A variety of indices can be invoked to try to quantify \r\ncluster quality for a given K; in addition to this, it is decided to seek the best value of K by testing the \r\ninfluence of K on ensuing seismic hazard analyses. Monte Carlo synthesis generates synthetic catalogues for \r\neach K value, from which peak ground acceleration (PGA) hazards are calculated and compared against \r\nresults from the observed catalogue to choose acceptable K values. To summarise the results, seismic hazard \r\nmaps are constructed for two acceptable values of K (8 and 27) for Java from the Poisson declustered \r\ncatalogue of shallow earthquakes using the Boore, Joyner, Fumal attenuation law. Not surprisingly the \r\nsmaller value of K with 8 clusters (progressed to zones) produces the smoother hazard map. All of the maps \r\nindicate highest hazard around the Sunda Strait and a general expectation in Java Island of 100-300 cm/s^-2 \r\nwith one-in-ten chance of exceedance in 50 years."^^ . "2008" . .
