Disruption of the Mauna Loa magma system by the 1868 Hawaiian earthquake: Geochemical evidence. Disruption of the Mauna Loa magma system by the 1868 Hawaiian earthquake: Geochemical evidence.
To test whether a catastrophic earthquake could affect an active magma system, mean abundances (adjusted for "olivine control") of titanium, potassium, phosphorus, strontium, zirconium, and niobium of historic lavas erupted from Mauna Loa Volcano, Hawaii, after 1868 were analyzed and were found to decrease sharply relative to lavas erupted before 1868. This abrupt change in lava...

The physics of debris flows — A conceptual assessment The physics of debris flows — A conceptual assessment
Debris flows exhibit conspicuous dynamic interactions among their solid and fluid constituents. Key features of the interactions are neglected in traditional theories that treat debris flows as viscoplastic continua or as uniformly dispersed grain flows, but improved understanding of grain-grain and fluid-grain interactions has emerged from recent experimental and theoretical research...

A detailed chronology of the most recent eruption period at Mount Hood, Oregon A detailed chronology of the most recent eruption period at Mount Hood, Oregon
The most recent eruptive period of Mount Hood volcano, the Old Maid eruptive period, was characterized by volcano-hydrologic events (hydrologic events initiated by volcanic activity) which resulted in extensive lahar inundation in the White, Sandy, and Zigzag River drainages and produced a lithic pyroclastic flow which traveled at least 9 km down the White River from the vent area at...

Reconnaissance investigation of sediment distribution, erosion, and transport in the upper Deschutes River, Deschutes County, Oregon, November 1986 Reconnaissance investigation of sediment distribution, erosion, and transport in the upper Deschutes River, Deschutes County, Oregon, November 1986
A preliminary investigation of sediment distribution, erosion, and transport in the upper Deschutes River was conducted in response to the perceived problem that brown trout spawning gravels were being rendered unusable due to an accumulation of fine-grained sediment. Contrary to the contention that channel gravels are being covered by fine-grained sediment, examination of the river...
