Due to the high level of seismicity at the end of the field survey, a vertical-component seismic station was left near the Spanish base, which operated for a few more weeks. During December 1998 only 8 VT events were recorded, a rate similar to the average of a few tens of events per...
Consequently, some of the main earthquake engineering issues that arose are the multiple locations where the code-mandated seismic actions were exceeded in more than one of the main events of the sequence and the number of pre- and low-code existing buildings that suffered heavy damage or ...
The ordinates of the spectrum cannot be related to any single seismic event, but to the complexity of events which can happen on the site. They arecalculated by statistical-probabilistic procedures now in common use. View chapterExplore book ...
One major earthquake is followed days, months, or even years later by other major earthquakes (Amos and Cline 2000) and such observation of near time extreme events are typically called earthquake storm. With no surprise in the past 25 years, Turkiye has experienced a series of major ...
contribute also to damping of building motions even during relatively small seismic events. In the event of a significant seismic event, the friction (i.e., Coulomb) damping, and the viscous damping effected by the VE material, both contribute to damping of seismic distortions in the building ...
The algorithm is further validated through engineering case studies to investigate semi-active control strategies in response to random seismic events. The results show that the seismic reliability of the machine learning-based semi-active control algorithm is significantly higher than that of the ...
The vertical distribution of seismic events indicates that the seismic behaviors of the sedimentary cover and the crystalline basement are grossly similar, with the exception of the Molasse basin, which seems to be less seismically active. In itself, the bathymetry of the sedi- mentary cover ...

Finally, all events belonging to any group of multiplets with a minimum size of 2 events were classified as ‘multiple events’ (ME). Obtained results revealed the presence of 231 ME in sub-cluster 1 and 382 ME in sub-cluster 2, which were used in double-difference relocation. 2.4. ...
During October 2022–April 2023, a shallow earthquake sequence occurred onshore South Evia Island near the villages Zarakes and Almyropotamos (Fig.1; Evangelidis and Fountoulakis2023). The sequence initiated on 25 October 2022 (Fig.1) with small size events that occurred in the vicinity of ...
