Abstract

Representation of the earthquake source is an important element in seismic hazard analysis and earthquake simulations. Source models span a range of conceptual complexity-from simple time-independent point sources to extended fault slip distributions. Further computational complexity arises because the seismological community has established so many source description formats and variations thereof; what this means is that conceptually equivalent source models are often expressed in different ways. Despite the resultant practical difficulties, there exists a rich semantic vocabulary for working with earthquake sources. For these reasons, we feel it is appropriate to create a semantic model of earthquake sources using an ontology, a computer science tool from the field of knowledge representation. Unlike the domain of most ontology work to date, earthquake sources can be described by a very precise …
