The Eyjafjallajökull eruption of 2010 demonstrated the far-reaching impact of ash clouds and the vulnerability of our jet-based society to them, prompting a review of procedures to detect, warn, and forecast ash cloud hazards to aviation. The years since 2010 have seen marked improvements in satellite technology, more accurate ash-dispersion models that integrate simulations with observations, and...... hiện toàn bộ
Elastic source model of the North Mono eruption (1325–1368 A.D.) based on shoreline deformationBulletin Volcanologique - Tập 72 - Trang 1141-1152 - 2010
Wil Shaffer, Marcus Bursik, Carl Renshaw
Topographic data from the Shuttle Radar Topography Mission (SRTM) captures the permanent deformation of a prominent highstand of Mono Lake, California USA. Deformation of the Dechambeau Ranch highstand shoreline was measured using the elevation of the beach berm—shoreline bluff break-in-slope. Point source models and a boundary element dike model were used to approximate the source of deformation ...... hiện toàn bộ
An application of factor analysis to basic volcanic rock geochemistryBulletin Volcanologique - Tập 38 - Trang 1070-1089 - 1974
D. M. Shaw, C. Dupuy, M. Fratta, J. Helsen
Factors analysis is useful for studying the interrelationships of trace and major elements in sets of rock analyses. Its application to basic volcanic rocks show various features: (i) the principal factors relate to variation among mineral components; (ii) the behaviour of K is similar to that of Rb, Ba, Sr and in some cases P, W, Tl also; (iii) the coherence of Tl with K and Rb is often masked by...... hiện toàn bộ
Thermal histories and emplacement dynamics of rhyolitic obsidian lavas at Valles caldera, New MexicoBulletin Volcanologique - Tập 84 - Trang 1-18 - 2022
S. M. Kenderes, K. S. Befus, A. N. Bryson, A. G. Whittington
The emplacement behaviors and the associated hazards of silicic lavas remain poorly understood because detailed real-time observations have only been made during a few modern eruptions. Therefore, we rely on older well-preserved glassy rhyolites like Banco Bonito and the VC-1 Rhyolite from the Valles caldera, New Mexico to constrain the emplacement behaviors of silicic lavas. Continuous whole core...... hiện toàn bộ
