The trachydacite complex of Mammoth Mountain and an array of contemporaneous mafic volcanoes in its periphery together form a discrete late Pleistocene magmatic system that is thermally and compositionally independent of the adjacent subalkaline Long Valley system (California, USA). The Mammoth system first erupted ca. 230 ka, last erupted ca....
Fine-grained linings of leveed channels facilitate runout of granular flows
B.P. Kokelaar, R. L. Graham, J.M.N.T. Gray, James W. Vallance
2014, Earth and Planetary Science Letters (385) 172-180
Catastrophic dense granular flows, such as occur in rock avalanches, debris flows and pyroclastic flows, move as fully shearing mixtures that have approximately 60 vol.% solids and tend to segregate to form coarse-grained fronts and leveed channels. Levees restrict spreading of unconfined flows and form as coarse particles that become...
Structure and seismic hazard of the Ventura Avenue anticline and Ventura fault, California: Prospect for large, multisegment ruptures in the Western Transverse Ranges
Judith Hubbard, John H. Shaw, James F. Dolan, Thomas L. Pratt, Lee J. McAuliffe, Thomas K. Rockwell
2014, Bulletin of the Seismological Society of America (104) 1070-1087
The Ventura Avenue anticline is one of the fastest uplifting structures in southern California, rising at ∼5 mm/yr. We use well data and seismic reflection profiles to show that the anticline is underlain by the Ventura fault, which extends to seismogenic depth. Fault offset increases with depth, implying that the...
