Volcanic hazards in the eastern Mediterranean pose a significant threat to local communities, human infrastructure and tourism. A thorough understanding of the individual volcanoes and the underlying magmatic systems is therefore of great interest to provide profound quantification of the related volcanic hazards. The proposed research project will focus on the Kolumbo submarine volcano in the southern Aegean that last erupted in 1650 AD with a violent explosion generating a destructive tsunami. During the recent decades, Kolumbo was associated with recurring seismic unrest, the cause of which is still unresolved. Today, there is little knowledge about the geometry of the magma plumbing system of Kolumbo and its relation to the magmatic system feeding the nearby Santorini caldera. Within the SEISMOS-KOLUMBO project, I will analyze in detail the microearthquake swarm activity below the Kolumbo volcano, for the time span 06/2006-03/2007, to elucidate the causes of recurring seismic unrest below Kolumbo. I will further investigate records of seismic attenuation and scattering from microearthquakes in the Kolumbo region to image the geometry and relation of different fluid reservoirs and geological units below and near the volcano, which will lead towards a better understanding of the Kolumbo submarine volcano.

东地中海的火山灾害对当地社区、人类基础设施和旅游业构成重大威胁。因此，彻底了解个别火山和底层岩浆系统，对提供有关火山灾害的深刻量化非常有意义。拟议的研究项目将侧重于爱琴海南部的Kolumbo海底火山，该火山最后一次爆发是在公元1650年，当时发生了一次猛烈的爆炸，引发了毁灭性的海啸。近几十年来，科隆博经常发生地震动乱，其原因仍然没有得到解决。今天，人们对科隆博岩浆管道系统的几何形状及其与附近圣托里尼火山口岩浆系统的关系知之甚少。在SEISMOS-KOLUMBO项目中，我将详细分析Kolumbo火山下的微震群活动，时间跨度为06/2006-03/2007，以阐明Kolumbo火山下反复发生地震动荡的原因。我将进一步调查记录的地震衰减和散射的微震在Kolumbo地区的图像的几何形状和不同的流体储层和地质单位下面和附近的火山，这将导致更好地了解Kolumbo海底火山。
