| Abstract: | A number of cases where earthquake-induced damage was massive or presented interesting distribution patterns in recent earthquakes are presented.The highly serious damage along reactivated seismic faults and fractures is discussedfor the earthquakes of Pyrgos (Greece), Egio (Greece) and Kobe (Japan). Additionally, we describe characteristic types of building failure in the earthquake of Egio,caused by the coexistence of surficial faulting and liquefaction. Of particularinterest is the damage pattern in the Kobe and Dinar earthquakes, attributed to seismicwave directivity, caused by migration of the earthquake source. Finally, a specialcase of building damage is described for the case of the Adana, Turkey earthquake,which is connected to the shape and the azimuthal location of buildings in respectto the epicentre. All the above cases are valuable sources of information and can be utilizedin the reduction of seismic risk in constructions and urban complexes. |
