These data show the details of aseismic fault failure, preseismic, coseismic and postseismic deformation, earthquake nucleation, volcanic deformation and volcanic processes. Theoretical modeling of these processes suggests testable physical explanations in term of physics of failure, the role of fluids in the crust, strain redistribution, and likely properties of fault zone materials. Very near-field data on slow slip, earthquakes and dynamic rupture were obtained in fault zones at 3.6 km depth in South Africa, a few 10\u2019s of meters from earthquakes from M=-4.5 to M=2.",
