| Abstract: | We collect 1974 broad-band velocity records of 94 earthquakes (M
L
=2.8∼4.9, Δ=13∼462 km) from seven stations of the Fujian Seismic Network from March 1999 to March 2007. Using real-time simulation, we
obtain the corresponding acceleration and then adopt different models to analyze the seismic data. As a result, a new attenuation
relationship between PGA and PGV of the small and moderate earthquakes on bedrock site in Fujian region is established. The
Yongchun earthquake occurred recently verifies the attenuation relationship well. This paper provides a new approach for studying
the ground motion attenuation relationship using velocity records.
