Internal Structure of an Endogenous Andesitic/Dacitic Dome Complex--Augustine Volcano

9405471 Kienle世界各地成千上万的人生活在活跃的圆顶和圆顶复合体的基础上。 这个项目是开发一个积极增长的内源性圆顶复杂的定量三维内部视图。 PI计划通过奥古斯丁火山中央圆顶复合体对P波速度进行断层成像。 用大约7 000条地震射线对喷口周围大约1立方公里（半径500米）的体积进行取样。 在火山山顶附近工作所提供的实验设计在地质层析成像领域是独一无二的，并且要获取的照明角度套件与医学层析成像中所采用的照明角度相比，更类似于地球物理学中通常使用的照明角度。 预计分辨率将小于50米。 这是在美国的第一次尝试，以获得详细的内部结构和生长过程的一个容易接近和活跃的内源性圆顶复杂的知识。

9405471 Kienle Thousands of people around the world live at the bases of active silicic domes and dome complexes. This project is to develop a quantitative three-dimensional interior view of an actively growing endogenous dome complex. The PIs plan to tomographically image P-wave velocities through the central dome complex of Augustine Volcano. The volume to be sampled with some 7,000 seismic rays is about 1km3 (500 m radius) around the vent. The experimental design afforded by working near the summit of a volcano is unique in the world of geotomography, and the suite of illumination angles to be acquired is more similar to those employed in medical tomography than those generally used in geophysics. Expected resolution will less than fifty meters. This is a first attempt in the U.S. to gain detailed knowledge of the interior structure and growth processes of a readily accessible and active endogenous dome complex.
