Volcano-tectonic evolution of the Christiana-Santorini-Kolumbo marine volcanic field / central Aegean Sea

火山灾害和风险缓解是全球地球科学的核心，约有8亿人生活在受火山爆发威胁的地区。火山以复杂的方式与环境相互作用，更好地了解这些相互作用具有很高的科学和社会经济重要性。Christiana-Santorini-Kolumbo海相火山场长100公里，宽45公里，发育于Hellenides中一个上新世至全新世的复杂裂谷体系中。这里是1956年发生的欧洲20世纪最大的7.4级浅层地震。Anhydros盆地包含与圣托里尼火山岛相邻的科伦坡火山链。大约3600年前的青铜时代晚期，所谓的“米诺斯”是圣托里尼岛的最后一次普林尼火山喷发，随之而来的是毁灭性的海啸。通过对一组独特的反射地震资料进行再处理，本项目力求：1)重建单个盆地的裂谷过程。2)裂谷构造与火山活动的相对时间和因果关系研究。(3)研究米诺斯火山爆发后圣托里尼火山口的崩塌和随后的火山构造叠印。

Volcanic hazards and risk mitigation lie at the heart of global geoscience, with about 800 million people living in regions threatened by eruptions. Volcanoes interact with their environments in complex ways, and better understanding of these interactions is of high scientific and socio-economic importance. The 100-km-long and 45-km-wide Christiana-Santorini-Kolumbo marine volcanic field developed in a complex rift system of Pliocene to Holocene age within the Hellenides. Here, the largest 20th century shallow earthquake in Europe of magnitude 7.4 took place in 1956. The Anhydros basin contains the Kolumbo volcanic chain adjacent to the volcanic island of Santorini. The so-called "Minoan" in the Late Bronze Age about 3600 yrs ago was the last Plinian eruption of Santorini, which was followed by a destructive tsunami. After reprocessing of a unique reflection seismic data compilation, this project strives for: 1) Reconstructing the rift processes of the individual basins. 2) Studying the relative temporal and causal relationship between rift tectonics and volcanism. 3) Investigating the collapse of the Santorini caldera after the Minoan eruption and volcano-tectonic overprint afterwards.
