“…This yields a mean geological slip rate of about 0.1 mm/year since the Pliocene for the Bolvadin Fault. This slip rate value best fits with the rates calculated for dip-slip normal faults in western Anatolia, Greece, and Italy (Caputo, 1995;Caputo et al, 2004;Pavlides and Caputo, 2004;Papanikolaou et al, 2005;Özkaymak et al, 2011;Özkaymak, 2015;Tsodoulos et al, 2016;Özalp et al, 2018).…”

“…Quaternary numerical methods commonly used in geologic slip rate calculations include radiocarbon, optically and infrared‐stimulated luminescence (OSL and IRSL, respectively), cosmogenic radionuclide dating, uranium series, dendrochronology, and many others (Cortés et al, 2012; Lienkaemper & Ramsey, 2009; Tsodoulos et al, 2016). It is generally best practice to obtain as many ages as possible from separate samples of the relevant units, features, or surfaces and to utilize multiple dating methods.…”

Seismic Hazard Analyses From Geologic and Geomorphic Data: Current and Future Challenges

et al. 2020

The loss of life and economic consequences caused by several recent earthquakes demonstrate the importance of developing seismically safe building codes. The quantification of seismic hazard, which describes the likelihood of earthquake-induced ground shaking at a site for a specific time period, is a key component of a building code, as it helps ensure that structures are designed to withstand the ground shaking caused by a potential earthquake. Geologic or geomorphic data represent important inputs to the most common seismic hazard model (probabilistic seismic hazard analyses, or PSHAs), as they can characterize the magnitudes, locations, and types of earthquakes that occur over long intervals (thousands of years). However, several recent earthquakes and a growing body of work challenge many of our previous assumptions about the characteristics of active faults and their rupture behavior, and these complexities can be challenging to accurately represent in PSHA. Here, we discuss several of the outstanding challenges surrounding geologic and geomorphic data sets frequently used in PSHA. The topics we discuss include how to utilize paleoseismic records in fault slip rate estimates, understanding and modeling earthquake recurrence and fault complexity, the development and use of fault-scaling relationships, and characterizing enigmatic faults using topography. Making headway in these areas will likely require advancements in our understanding of the fundamental science behind processes such as fault triggering, complex rupture, earthquake clustering, and fault scaling. Progress in these topics will be important if we wish to accurately capture earthquake behavior in a variety of settings using PSHA in the future. Plain Language Summary Growing infrastructure and increasing population have caused significant loss of life due to recent large earthquakes, with the 2008 M w 7.9 Wenchuan and 2005 M w 7.6 Kashmir earthquakes each causing greater than 50,000 deaths. These earthquakes highlight the need for the development of building codes designed to withstand the strong ground shaking caused by earthquakes, as reinforced infrastructure is one of the most important factors for preventing fatalities due to ground shaking from earthquakes. Identifying the seismic hazard of a region, or the likelihood of ground shaking at a site due to potential earthquakes over time, is a key ingredient for informing a defensible building code. Here, we focus on current and future advances in how data from the fields of geology and geomorphology contribute to the most widely used type of seismic hazard model. These geologic data represent vital components to seismic hazard models, as they can provide information about the location and types of earthquakes that can occur over long, thousands of years, time periods, that cannot be obtained using other methods. We discuss some of the most pressing scientific issues about these data that are important for the development of seismic hazard models and defensible building codes.

“…Antithetic to the Larissa and Tyrnavos faults and bordering to the north the graben are the Gyrtoni and Rodia Faults [7,9,11,18]. For both faults, palaeoseismological investigations and morphotectonic analyses document the recent linear morphogenic activity [19], however, none of them reactivated during the March 2021 seismic sequence.…”

On 3 March 2021, a strong shallow earthquake affected northern Thessaly, Greece, with an epicenter close to Damasi village causing significant destruction of many stone houses. In this contribution, we provide fieldwork observations, satellite radar interferometry, mapping of the active faults exposed in the epicentral area, liquefactions and coseismic surface ruptures, and preliminary geomorphological analyses of the epicentral area. The geomorphological analysis is based on air photographs, digital surface models analysis, Real-Time Kinematik (RTK) measurements with Global Navigation Satellite System (GNSS) receivers, and data from UAV flight campaigns. Although the seismotectonic setting of the area is complex and there is an apparent mismatch between field and interferometric data, the results of our investigations suggest that at least three fault segments were reactivated by the major shocks of the March seismic sequence. These tectonic structureslikely represent the westward propagation of the Tyrnavos Graben, where newly formed and inherited low-angle faults interplay in a complex manner.
