An impressive 18-25 cm elevation of Samos was observed after the strong seismic vibration of 6.7 on the Richter scale that occurred on Friday, October 30 at 1:51 p.m., focusing on the sea area 16 km northwest of the island .
According to an announcement by the research team of the Department of Geology and Geoenvironment of the National University and Kapodistria of Athens, composed of Professor Dr. Efthymi Lekka, υποψ. Dr. Spyridon mavrouli, υποψ. Dr. Marilia gogou, υποψ. Dr. Ioanna Tryanatafyllou, with the participation of the seismologist Dros Gerasimos Papadopoulos, One of the most important findings is the tectonic uplift, which was observed both in the northern and southern parts, that is, in the ascending part of the fault, which was activated in the maritime zone to the north of the island.
The research team carried out extensive field research on the Samos earthquake, its effects on buildings, accompanying geodynamic phenomena, the tsunami, and significant ground deformations.
As noted in the northern part, the tectonic elevation was certified in the coastal towns of Karlovasi (Fig. 1, 2, 3a, 3b), while in the southern part in the coastal towns of Potokaki, Pythagorion and Psili Ammos (Fig 4, 5, 6).
From all the in situ observations, it appears that the permanent seismic elevation of the island is of the order of 18-25 cm.
The research also indicates that the significant landslides are landslides, which are geodynamically connected to the submarine fault with AD direction and with a northward slope. A typical case, it is emphasized, is the landslide in the coastal town Avlakia that resulted in the temporary cessation of traffic (Fig. 7). Additional major rock falls were reported at Kerketeas south of Karlovasi.
Research continues and a more comprehensive report will soon be published in the Newsletter of Environmental, Disaster, and Crisis Management Strategies, of the Graduate Program “Environmental, Disaster & Crisis Management Strategies” of the National and Kapodistrian University of Athens.
