Slip nucleation during earthquakes is apparently analogous to rupture nucleation within an intact rock sample subjected to triaxial loading. The observations indicate that both these nucleation processes initiate within a relatively small volume and in both the slip propagates unstably along a quasi-planar surface. In both processes a single, pre-existing, shear fracture cannot nucleate the large-scale slip, and in both a "process zone" that includes several interacting fractures in a small volume are required to initiate the unstable slip. Both processes require rupture of intact rocks, generate complex fracture geometry, and are associated with intense energy-release-rate during slip. Recent observations and analyses are used to correlate rupture nucleation in laboratory tests with nucleation events of large earthquakes. It is proposed that earthquake nucleation occurs by the interaction among multiple fractures within a small volume that develops into unstable yielding of the healed fault zone.

accompanying the 1989 Loma Prieta earthquake
resemble that associated with earthquakes along deep-seated reverse faults. These featinclude ground breakage,
surfacedeformation, aftershock distribution, and a
component of reverse slip deduced from geodetic and strong ground motion
data. To explore these deformational features of the earthquake, we derive an
analytical model for the deformation of a layered sequence due to slip along
a deep-seated fault. Our model includes horizontal elastic layers, using
configurations withas many as nine layers of
different shear moduli. We applied this layered
model to the Loma Prieta region and found that the
better solutions are for five-layer sequences in which the shear moduli of the layers increase downward. The model
predicts the distribution of aftershocks in the upper 5 km better than a
model with uniform rheology. The model also
accurately predicts the location of the horizontal extension zone in the
The bending of lines at the proximity of faults, known as fault-drag, is examined here by analytical and numerical (finite-elements) models. Frequently, the bent lines are convex toward the direction of the fault motion, and this convexity is known as "normal-drag", whereas an inverted sense of convexity is known as "reverse-drag". We first analyze the slip along a short fault embedded in a large elastic or elastic-plastic plate. The analysis indicates that reverse-drag is the expected drag along the short fault, and that the normal-drag reflects continuous deformation which preceded the faulting. Models with faults of high friction coefficient display smaller drag than frictionless faults; this suggests that the drag intensity is not simply related to the frictional resistance. We also model the drag along a normal fault with curved, "anti-listric" surface embedded in an elastic-plastic medium; this model also indicates that the reverse-drag is the prevailing one. The predictions of the present models agree well with previous experimental results of slip along short faults in wax and plasticene samples. Finally, we show that the normal-drag observed in association with long faults reflects prefaulting deformation which is concentrated within a narrow shear zone.

Beam Experiments Under Confining Pressure: Tensile Strength and Tensile
Elastic Moduli of Three Sedimentary Rocks
The strength and elastic properties of three sedimentary rocks were
measured with a four- point beam device. The device was placed inside a
pressure vessel and the beam samples were deformed by combined application of
bending moment and confining pressure. The tensile and compressive stresses
within the beams were determined from the measured loads and the axial
strains at the top and bottom of the beam; for the stress calculations we
used the formulation of Yokoyama (1988). The experiments were conducted with
