What is general behavior and what are system or location specific characteristics during strombolian explosions

斯特隆博利火山每10-20毫米喷发一次，这使斯特隆博利火山成为一个天然的火山学实验室，特别是研究喷发过程。在2007年3月的大喷发之后，Pizzo Sopra La Fossa下面著名的火山口平台已经被显著地重塑，现在可以直接看到斯特隆博利火山东北火山口的岩浆。这使得斯特龙博利火山成为研究斯特龙博利火山爆发时的原位过程（即岩浆-空气界面处气泡破裂）的绝佳目标。在这个提议中，我们想研究这些爆炸，并将我们的观察结果与早些时候在其他火山上观察到的结果进行比较。进行这项侦察研究的原因之一是，观察到在各种火山上记录的斯特隆波利爆炸信号显示出各种各样的特征，我们想了解气泡破裂时的一般过程，以及系统或火山特有的情况。只有通过比较来自不同系统/地点的数据，我们才能开发出一个更通用的泡沫破裂模型。这种比较将基于我们的多普勒雷达观测与其他数据集（如次声、红外和地震）的广泛相关性以及详细的模型计算。

Eruptions at Stromboli volcano are known to occur about every 10-20mm making Stromboli volcano a natural volcanological laboratory, especially for studying eruption processes. Following the major eruption in March 2007, the well known crater terrace below the Pizzo Sopra La Fossa has been significantly reshaped now allowing a direct view at the magma in the NE crater of Stromboli volcano. This makes Stromboli an excellent target to study in situ processes at the onset of strombolian eruptions, i.e. gas bubbles bursting at the magma-air interface. In this proposal we want to study those explosions and compare our observations to ones made earlier at other volcanoes showing strombolian activity. One of the reasons for this reconnaissance study is the observation that signals of strombolian explosions recorded at various volcanoes show a large variety of features and we want to understand what are general processes during bubble bursts and what is system or volcano specific. Only through comparing the data from different systems/localities will we be able to develop a more general model for bubble bursts. This comparison will be based on an extensive correlation of our Doppler radar observations with other data sets (like infrasound, infrared and seismics) as well as detailed model calculations.
