Abstract
One of the key information required for earthquake disaster mitigation and management is the prior understanding of the impact of strong ground motion. The earthquake early warning system (EEW) is one of the upcoming instruments to effectively reduce the seismic risk, and it provides an alert of imminent damage by quick determination of earthquake source parameters based on the simple onsets. The issues of improving accuracy and applicability are still controversial. In this paper, an attempt has been made to show the influence of local site effects on the earthquake early warning on strong ground motion parameters. The most commonly used EEW parameter; the average period of the initial 3 s of the ground motion records has been used. The analysis has been carried out with the basis of existing measurable ground motion records from the Japanese dataset. The results showed how the earthquake early warning parameter varies for different bedrock motions, surface motions, and also for different site classes. It indicates that the local site effects are significantly influencing the earthquake early warning parameter considered.
