About the Symposium

The 5th International Symposium on the Effects of Surface Geology on Seismic Motion (ESG5) will be hold on August 2016 and take place in Taipei, Taiwan. The symposium will discuss the site effect related topics especially focus on main theme which is “Challenges of Applying Ground Motion Simulation to Seismology and Earthquake Engineering”. The symposium is jointly host by National Center for Research on Earthquake Engineering, Taiwan (NCREE) and National Taiwan University, Taiwan (NTU).

In the past few decades, the site effects of seismic ground motions induced by surface geology and structure were getting emphatic in seismology and earthquake engineering. Possible disasters for cities located on alluvium basin or plain induced from site amplification during earthquake should be taken seriously consideration. First priority problem related to symposium theme is to simulate high frequency motions. However, shallow velocity structures were still unclear for many regions in the world that it still need more exploration such as microtremer or borehole experiences.


The symposium is organized from ESG working group under IASPEI (International Association of Seismology and Physics of the Earth's Interior) and IAEE (International Association of Earthquake Engineering) since 1980's. These two committees had focus on research of development of strong ground motion during former four symposiums. First one was in 1992 held in Odawara, Japan with main topic of blind prediction experiments at Ashigara Valley. Second one was in 1998 took place in Yokohama, Japan which was focus on simulation of Kobe earthquake. Third one was in 2006 held in Grenoble, France concentrated on noise blind test of simulation in Grenoble basin. The fourth symposium was 2011 in Santa Barbara, America and had special discussions of the suitability of Vs30 during the time.
