| Abstract: | Relative durations of strong ground motions from 109 station records of MS8.0 Wenchuan earthquake are calculated based on 70% and 90% energy duration definition.Attenuation relationships of the durations under different definitions are statistically analyzed for three component records and 90% duration definition is recommended.The relationships in the hanging wall and footwall of earthquake faults are compared and the ratios of vertical duration to horizontal duration are discussed for different areas. |
| |
| Keywords: | Wenchuan earthquake strong ground motion record relative duration attenuation relationship hanging wall/foot wall |
