Pulsatory andesite lava flow at Bagana Volcano
[1] Using a time series of TerraSAR-X spaceborne radar images we have measured the pulsatory motion of an andesite lava flow over a 14-month period at Bagana Volcano, Papua New Guinea. Between October 2010 and December 2011, lava flowed continuously down the western flank of the volcano forming a 3 km-long blocky lava flow with a channel, levees, overflows and branches. We captured four success...
متن کاملTopographic Variability: Implications for Lava Flow Modeling
Introduction: Glaze et al. [1] and Baloga et al. [2] have both recently indicated the importance of understanding the scale of a lava flow relative to the surrounding topography in extracting inferences about rheologic changes and the interpretation of the style of emplacement. The underlying scientific issue is whether flow emplacement is controlled by the largescale topographic inclination or...
متن کاملEmplacing a Cooling-Limited Rhyolite Lava Flow: Similarities with Basaltic Lava Flows
Accurate forecasts of lava flow length rely on estimates of eruption andmagma properties and, potentially more challengingly, on an understanding of the relative influence of characteristics such as the apparent viscosity, the yield strength of the flow core, or the strength of the lava’s surface crust. For basaltic lavas, the relatively high frequency of eruptions has resulted in numerous oppo...
متن کاملA test of the homogeneous array concept using the Hat Creek arrayDavid
In this memo, we review the three basic schemes of obtaining low spatial frequency data for millimeter array observations: (1) use of a large single dish, (2) interferometry with a multi-size array, and (3) scanning with a homogeneous array. We describe an application of the homogeneous array concept using the three antenna Hat Creek array. In an appendix, we analyze the eeects of random, uncor...
