S15: The July 17, 2006 Java Earthquake and Tsunami:  What are we  
learning?

At 08:19 GMT on 17 July 2006, a very large Mw=7.7 earthquake ruptured  
in the near-trench region south of western Java, Indonesia causing a  
locally devastating tsunami responsible for numerous casualties. This  
event is unique in that preliminary data suggest the earthquake had a  
very long duration for its magnitude, making it the first classic  
slow-source “tsunami earthquake” (TsE) to occur in the past 10  
years.  This event joins a short list including only three other TsE  
events that have occurred since the development and deployment of  
modern broad-band global seismology: Nicaragua 1992; Java 1994; and  
Peru 1996.  The precise rupture processes and controlling mechanism  
of such TsEs are poorly understood, in part because they likely occur  
in a weak subduction interface that is often considered to be unable  
to nucleate earthquake rupture.  Additionally, the mechanisms that  
are responsible for generating disproportionately large tsunamis from  
these events are not well understood.  This session invites  
contributions that seek to improve identification and our  
understanding of this and other such slow-source TsE events, and the  
processes that control their tsunami generation.  We are particularly  
interested in contributions that incorporate observational,  
theoretical and/or modeling that specifically address this most  
recent event TsE.
