Active Tectonics in the Hellenic Volcanic Arc: The Kolumbo Submarine Volcanic Zone

Abstract

This paper studies the rupture system of the Anydhros

Strike slip tectonics and transtensional deformation in the Aegean region and the Hellenic arc: Preliminary results

“…Tibaldi et al (2008) suggest that Nisyros volcanic field has developed within a major NE-trending graben with strong evidence of left-lateral strike-slip component. In accordance to that, Sakellariou et al (2010) have proposed that the Santorini-Koloumbo volcanic field has developed within and along the transtensional NE-SW trending Anydros basin and that the volcanic centers of Christiana, Kameni and Koloumbo are aligned along a major strike-slip fault-zone. Piper & Perissoratis (2003) have shown that the offshore area north and south of Milos is strongly offset by prominent N-S faults and at least one major NE-trending active fault and argue that this fault pattern is a consequence of NE-trending sinistral shear.…”

Interpretation of single channel seismic profiles obtained by HCMR during the last decades ( Figure 2) in the frame of several projects and cruises: HERMES -south and southwest Crete, KM3Net -Southwest Peloponnese, THERA -Santorini area (Sigurdsson et al, 2006;Sakellariou et al, 2010), Gulf of Corinth (Moretti et al, 2004;Lykousis et al, 2007;Sakellariou et al, 2007a), AMPHITRITE -North Evia Gulf (Sakellariou et al, 2007b), North and South Ikarian Basins (Lykousis et al, 1995) and other ( Figure 2). 7.…”

Historical bathymetric charts and the evolution of Santorini submarine volcano, Greece

“…[] and Sakellariou et al . [] propose that the basin is bounded by two overlapping dextral strike‐slip faults, which may have controlled the spatial distribution of the volcanic centers of the Santorini volcanic field. Direct evidence of such faults (e.g., flower structures) have not, however, been observed in multichannel seismic reflection profiles [ Hübscher et al ., ].…”

“…Seismic reflection profiles indicate that the south, north, and west basins of the caldera are underlain by >200 m of stratified material which Sakellariou et al . [] have divided into six subunits. Sakellariou et al .…”

Offshore Faulting in the Aegean Sea: A Synthesis Based on Bathymetric and Seismic Profiling Data

“…Piper and Perissoratis (2003) provided a synthetic map of both, new and previously known, offshore faults in the South Aegean Sea. Swath bathymetry and single channel seismic profiles have been used to map the faults in the area of Nisyros and Kos Islands (Tibaldi et al, 2008;Nomikou and Papanikolaou, 2011), around Santorini (Sakellariou et al, 2010) and in Christiana Basin, between Santorini and Milos Islands (Tsampouraki-Kraounaki et al, 2015).…”
