Description:  Recently, observations using dense arrays of  
instruments have revealed precise features of various geophysical  
phenomena related to faults and earthquakes. For example, dense  
temporary seismic networks show fault zone structures and stress  
fields around faults. GPS arrays detect temporal changes in  
postseismic deformations. Magnetotelluric measurements determine  
conductivities in and around fault zones. These precise features,  
together with direct measurements on faults, can clarify important  
unsolved problems in geophysics, such as fluid distributions in fault  
zones, origin of intraplate earthquakes, the nature of asperities on  
earthquake faults, deep structure of fault zones, and anelastic  
deformation in and around faults. In particular, many important  
results were obtained by dense temporary observations of earthquakes  
occurring in Japan, United States and the other countries, e.g., 2003  
San Simeon, 2004 Parkfield, 2004 Niigata, and 2007 Noto earthquakes.  
This session welcomes results from various kinds of dense geophysical  
observations, from both temporary and permanent networks. Submission  
of papers about modeling and theoretical analyses are also encouraged.
