Preliminary geologic map of the Puu Anahulu quadrangle, Hawaii Preliminary geologic map of the Puu Anahulu quadrangle, Hawaii
Vent deposits and lava flows from Hualalai Volcano and lava flows from Mauna Loa and Mauna Kea Volcanoes cover the Puu Anahulu 7 1/2-minute quadrangle. Hualalai's diffuse north-trending rift zone, marked by the large trachyte cone of Puu Waawaa and several basaltic spatter cones, is located mainly in the southwestern part of the quadrangle. Several Hualalai flows originated in the...

Dynamic pore-pressure fluctuations in rapidly shearing granular materials Dynamic pore-pressure fluctuations in rapidly shearing granular materials
Results from two types of experiments show that intergranular pore pressures fluctuated dynamically during rapid, steady shear deformation of water-saturated granular materials. During some fluctuations, the pore water locally supported all normal and shear stresses, while grain-contact stresses transiently fell to zero. Fluctuations also propagated outward from the shear zone; this...
