Late Holocene palaeogeographic evolution of the Lihoura coastal plain, Pteleos Gulf, Central Greece

E. Karymbalis et al.

Summary: The present study investigates the palaeogeographic evolution of the coastal Lihoura plain in central-eastern Greece during the Late Holocene. Through core drilling, sediment analysis, and geomorphological mapping, the study reveals that the plain was inundated by seawater during the Mid-Holocene and later transformed into a protected lagoonal environment due to the development of a limestone peninsula. A recent high energy marine inundation event was also recorded in the northern part of the plain. The study estimates the average rates of sea-level rise during certain time periods.

Late Quaternary Marine Terraces and Tectonic Uplift Rates of the Broader Neapolis Area (SE Peloponnese, Greece)

Efthimios Karymbalis et al.

Summary: This paper investigates the role of tectonic processes in the late Quaternary evolution of the coastal landscape in the Neapolis area. By studying marine terraces and using Optically Stimulated Luminescence (OSL) dating, the study finds a significant coastal uplift with a long-term uplift rate of 0.36 ± 0.11 mm/a.

Relative Sea Level Changes and Morphotectonic Implications Triggered by the Samos Earthquake of 30th October 2020

Niki Evelpidou et al.

Summary: On 30th October 2020, a Mw = 7.0 earthquake shook the eastern Aegean Sea near the northern coasts of Samos island, causing uplift of the whole island, infrastructure damage, and a small tsunami. Geological, geomorphological, and biological observations revealed a complex character for the uplift, with maximum vertical displacements in the northwestern part and subsidence in the southeastern part. The study validated the importance of tidal notches as markers of co-seismic events and provided insights into the complex tectonics of the area.

The Tsunami Caused by the 30 October 2020 Samos (Aegean Sea) Mw7.0 Earthquake: Hydrodynamic Features, Source Properties and Impact Assessment from Post-Event Field Survey and Video Records

Ioanna Triantafyllou et al.

Summary: Based on field surveys and various data, this study discovered that the tsunami was generated by seismic activity; the tsunami waves near Samos Island were the largest in the Aegean Sea since 1956; the height of the tsunami waves varied in different locations, possibly due to geographical factors.

Multiple Submerged Tidal Notches: A Witness of Sequences of Coseismic Subsidence in the Aegean Sea, Greece

Anna Karkani et al.

Summary: This paper reconstructs sequences of coseismic subsidences and relative sea-level changes in the Late Holocene Aegean islands through the shape of tidal notches. The analysis reveals that the subsidence trends are not continuous with gradual movement, but rather result from repeated coseismic vertical subsidences. The estimated average return times are approximately some centuries to one millennium, providing useful indications on the long-term tectonic trends in the Aegean region.
