A deterministic seismic risk macrozonation of Seville

The seismicity of the southwestern Iberian Peninsula is moderate but large events with long return periods occur (≈ 200 years). This exceeds life various generations, making population unacquainted seismic hazard. On one hand, this results in a low demanding code which increases vulnerability and, therefore, risk. other local emergency services must be properly prepared to face destructive event, plans and mitigation strategies. assumption enhances need assessing risk Seville civil protection context. For all aforementioned for lack instrumental data relevant earthquakes, assessment hazard area challenging. To do this, seismogenic zones new map Spain have been used as sources. peak ground acceleration (PGA) each scenario has calculated by means motion prediction equations (GMPE). estimate site effects, 1D model environment, shear wave velocity (Vs) top 5 m depicted based on standard penetration test (SPT). Seville’s building stock classified agreement previous works Lorca Barcelona determine its vulnerability. main goal work was investigate influence soil amplification behaviour different typologies. Therefore, final target plot damage scenarios expected under maximum credible earthquake deterministic (DSHA). As outputs, modelled showed that around 27 000 buildings would experience 26 suffer pre-collapse or even collapse. Thus, approximately 10% lose their dwellings. Regarding human loses, 22 people serious injuries die. Owing these conclusions, research evidences crucial implement plan tool mitigate probable consequences arise from threat.
