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 chemistry, accompa

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. Grain-flow

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 Crater Rock.
