Velocity models inferred from p-waves travel time curves in south Aegean

Abstract: The seismicity recorded during Ist January to 31st August 2005 from a new telemetry network installed and operating on the island of Crete, is used in an effort to obtain new velocity models for the area of south Aegean. The models are constructed from the P-waves travel time curves and are later used for the events relocation with the HYPOINVERSE algorithm and station delays calculation. Furthermore, results are discussed and compared with the ones derived from other significant previous works presented the l… Show more

“…The nal V P /V S ratio for the Cretan region was estimated to 1.78 (Fig. 5 Following, the initial catalogue (1446 events) was divided spatially into smaller regions using overlapping windows for further analysis and comparison with similar studies conducted in these regions (Delibasis et al 1999;Meier et al 2004;Nikolintaga et al 2007;Becker et al 2010). In total, four groups were considered: (A) Antikythera-Chania region (332 events), (B) Chania-Rethymno region (129 events), (C) Heraklion region (445 events), (D) Agios Nikolaos-Zakros region (349 events), where the October 12th 2021, M L =6.2 event took place (Fig.…”

“…In total, we obtained a dataset of 7410 events. The resulting catalogue was then divided spatially into six smaller regions (Figure 5) using overlapping windows for further analysis and comparison with similar studies conducted in these regions [39]. The events were evenly distributed across both overlapping areas.…”

“…Papazachos and Nolet have used a mean VP/VS=1.75 for their nonlinear tomography in the Hellenic arc (Papazachos & Nolet, 1997) and the same ratio have been used by Meier et al to obtain the 1D velocity models for western and central Crete (Meier, et al, 2004). Nikolintaga et al have used the first HSNC station recordings to obtain the 1D crust models for the South Aegean, their Wadati plots suggest a velocity ratio equal with 1.78 (Nikolintaga, et al, 2007). The same ratio has been used by Becker et al to obtain the 1D velocity models for central Crete with recordings from permanent stations as well as ocean bottom seismometers (Becker, et al, 2010).…”
