| Abstract: | Shaking maps are effective tools to describe ground motion and potential damage resulted from an earthquake, which include maps of Peak Ground Velocity （PGV） , Peak Ground Acceleration （PGA） and instrumental intensity. Based on the Ms3.7 earthquake occurred in Yangjiang area and recorded by the digital seismic network of South China on July 9, 2010, we used SAC and GMT to generate equivalent maps of PGV and PGA via ground motion parameters extracted from the recorded seismic waveform data. Then, this paper constructed the map of instrumental intensity from empirical table relations. The results show that Yangdong area has the biggest PGV and PGA, with an instrumental intensity degree of 4. The shape of the intensity contours on land looked like a half oval in near north-south direction. The calculation methods and research results of this paper have an important effect and a significant meaning on the shaking map generation and earthquake intensity rapid report in the western coast of Guangdong province. They also provide basic data for seismic fortification and seismic risk analysis in this area. |
