Identification of structural controls in an active lava dome with high resolution DEMs: Volcán de Colima, Mexico
[1] Monitoring the topography of active lava domes is critical for detecting changes that may trigger or influence collapse or explosive activity. Internal dome structure and conditions are more difficult to elucidate, but also play vital roles. Here, we describe the exposure (following an explosion) of significant scarps in the active dome at Volcán de Colima, Mexico, that are interpreted as e...
متن کاملSatellite radar data reveal short-term pre-explosive displacements and a complex conduit system at Volcán de Colima, Mexico
*Correspondence: Jacqueline T. Salzer, Department 2: Physics of the Earth, GFZ German Research Center for Geosciences, Telegrafenberg, 14473 Potsdam, Germany e-mail: [email protected] The geometry of the volcanic conduit is a main parameter controlling the dynamics and the style of volcanic eruptions and their precursors, but also one of the main unknowns. Pre-eruptive signals that originat...
متن کاملVolcanic Eruptions: Cyclicity During Lava Dome Growth
Glossary andesite magma or volcanic rock is characterised by intermediate SiO2 concentration. Andesite magmas have rheological properties that are intermediate between basalt and rhyolite magmas. Silica content in andesites ranges from approximately 52 to 66 weight percent. Common minerals in andesite include plagioclase, amphibole and pyroxene. Andesite is typically erupted at temperatures bet...
متن کاملUsing Automated Point Dendrometers to Analyze Tropical Treeline Stem Growth at Nevado de Colima, Mexico
The relationship between wood growth and environmental variability at the tropical treeline of North America was investigated using automated, solar-powered sensors (a meteorological station and two dendrometer clusters) installed on Nevado de Colima, Mexico (19° 35' N, 103° 37' W, 3,760 m a.s.l.). Pure stands of Pinus hartwegii Lindl. (Mexican mountain pine) were targeted because of their suit...
متن کاملTree growth response to the 1913 eruption of Volcán de Fuego de Colima, Mexico
The impact of volcanic eruptions on forest ecosystems can be investigated using dendrochronological records. While long-range effects are usually mediated by decreased air temperatures, resulting in frost rings or reduced maximum latewood density, local effects include abrupt suppression of radial growth, occasionally followed by greater than normal growth rates. Annual rings in Mexican mountai...
