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

众所周知，斯特龙博利火山每10-20毫米就会喷发一次，这使斯特龙博利火山成为一个天然的火山学实验室，特别是用于研究喷发过程的实验室。在2007年3月的大喷发之后，索普拉·拉福萨火山下方众所周知的火山口平台已经被显著重塑，现在可以直接看到斯特龙博利火山东北火山口的岩浆。这使得斯特龙博利成为研究斯特龙博利火山喷发开始时的现场过程的一个很好的目标，即在岩浆-空气界面上破裂的气泡。在这项提议中，我们想要研究这些爆炸，并将我们的观察结果与早些时候在其他火山上所做的显示斯特龙博勒活动的观察结果进行比较。进行这项侦察研究的原因之一是观察到，在不同火山记录的斯特龙博勒爆炸信号显示出各种不同的特征，我们想要了解气泡爆发期间的一般过程，以及系统或火山特有的过程。只有通过比较不同系统/地区的数据，我们才能开发出更普遍的泡沫破裂模型。这一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.
