Das Magnitude 8.8 Maule (Chile)-Erdbeben vom 27. Februar 2010 - Ingenieuranalyse der Tsunamischäden [Teil 2]

The Magnitude 8.8 Maule (Chile) earthquake of February 27, 2010 — Engineering analysis of tsunami damages.

The Maule (Chile) February 27, 2010 earthquake is regarded as one of the strongest earthquakes ever recorded world-wide. The seismic event triggered a tsunami which caused by several wave fronts serious damage alongside the coastal border.
Event-specific characteristics from the overlay of the effects from earthquakes and following flood wave (Tsunami) were motivation to examine building damage and to document their regional distribution, in the context of a reconnaissance mission of the engineering group of the German Task Force for earthquakes. The paper provides an impression from the tsunami induced damage to the different building types under the impact of time-varying sequence of extreme natural events. First results of the studies in [1] are related to the engineering analysis of earthquake damage. Therefore it can be referred to the overview of the building stock and the predominant structural systems in Chile given there. Damage caused by the tsunami is concentrated on rural and often less resistant traditional buildings in coastal areas. The main loading and impact components induced by the tsunami are used to explain the vulnerability of building types and the efficiency of simple structural measures. As the damage cases demonstrate, debris in its general sense has contributed to the observed effects.
