Beschreibung:
KeyGraph, a document-indexing (keyword-extraction) algorithm, is applied for a new purpose: Extracting active faults with risks of near-future large earthquakes from earthquake-sequences. This paper presents KeyGraph as an extractor of causalities from an event-sequence. This validates KeyGraph as a tool for showing why and which active faults are risky, as well as for showing why and which words abstract a document. The risky faults that are empirically obtained by KeyGraph correspond closely to real earthquake occurrences and seismologists' risk estimation
