摘要

本文利用环境地震噪声层析成像技术建立了唐库班帕拉胡火山的剪切速度模型。我们使用了2021年10月至2022年2月期间部署的为期三个月的55个临时网络的数据。我们将每个站点的垂直分量相互关联，提取经验格林函数，生成周期范围为1至6.5 s的群速度图。然后，我们构建了一个峰顶以下5公里深度的剪切波速度的三维模型。我们的分析揭示了高速和低速值的不同模式，与旧巽他火山口的存在、未绘制的局部结构和TPV周围的地表地热表现有关。我们确定了指示浅层储层的低速带和岩浆从地下向地表火山口迁移的路径。此外，观察到的高速带对应于冷却的岩浆体。

Revealing the shear-wave velocity structure of Tangkuban Parahu Volcano, West Java, Indonesia using Ambient Noise Tomography

We present a shear-velocity model for the Tangkuban Parahu Volcano (TPV) using ambient seismic noise tomography. We used data from a three-month 55-temporary netwok deployed between October 2021 and February 2022. We cross-correlated the vertical components at each station to extract an empirical Green's function, to generate group velocity maps within the periodicity range of 1 to 6.5 s. We then construct a three-dimensional model of shear-wave velocity to a depth of 5 km below the summit. Our analysis revealed distinct patterns of high and low velocity values, associated with the presence of the old Sunda caldera, unmapped local structures, and surface geothermal manifestation around TPV. We identified low velocity zones indicative of shallow reservoirs and pathways for magma migration from the subsurface to surface crater. Additionally, high velocity zones observed, correspond to cooled magmatic bodies.

期刊介绍： An international research journal with focus on volcanic and geothermal processes and their impact on the environment and society. Submission of papers covering the following aspects of volcanology and geothermal research are encouraged: (1) Geological aspects of volcanic systems: volcano stratigraphy, structure and tectonic influence; eruptive history; evolution of volcanic landforms; eruption style and progress; dispersal patterns of lava and ash; analysis of real-time eruption observations. (2) Geochemical and petrological aspects of volcanic rocks: magma genesis and evolution; crystallization; volatile compositions, solubility, and degassing; volcanic petrography and textural analysis. (3) Hydrology, geochemistry and measurement of volcanic and hydrothermal fluids: volcanic gas emissions; fumaroles and springs; crater lakes; hydrothermal mineralization. (4) Geophysical aspects of volcanic systems: physical properties of volcanic rocks and magmas; heat flow studies; volcano seismology, geodesy and remote sensing. (5) Computational modeling and experimental simulation of magmatic and hydrothermal processes: eruption dynamics; magma transport and storage; plume dynamics and ash dispersal; lava flow dynamics; hydrothermal fluid flow; thermodynamics of aqueous fluids and melts. (6) Volcano hazard and risk research: hazard zonation methodology, development of forecasting tools; assessment techniques for vulnerability and impact.
