Response spectrum predictions for potential near-field and far-field earthquakes affecting Hong Kong: Rock sites

Abstract

To realistically assess the seismic risk relating to built infrastructures in Hong Kong and in the neighbouring coastal cities of southern Guangdong province, it is necessary to predict ground shaking induced by different earthquake scenarios with good accuracy. A companion paper has described the modelling of the spatial and temporal distribution of the diffused seismic activities in the region, based on the newly-developed 'Expanding Circular Disc' (ECD) method. Representative Magnitude-Distance (M-R) combinations for both near-field and far-field earthquakes (in relation to Hong Kong) have been derived using the ECD method. The present paper describes the modelling of the response spectru..
