Comparison of Blind Detection of Liquefaction by Suzuki and SY Methods

Abstract:

To mitigate liquefaction hazard, real-time liquefaction monitoring technique is investigated. And the reverse liquefaction detection method from seismic records is the key point. The existing methods are limited and the reliability requires test. In 2011, an earthquake of magnitude 6.3 struck in New Zealand's South Island. Serious liquefaction phenomena were reported, which provides an opportunity to verify the existing liquefaction detection methods. Twenty-seven acceleration records within 50km to the epicenter are selected to perform a blind detection for existing two methods, including Suzuki and Sun-Yuan method. The blind detection results indicate that Sun-Yuan method obtains correct results for three known liquefied sites, and both method are correct for a reported non-liquefied site. The number of identically detected results is 22 by two methods. The identified results will be verified by actual observation for the 23 sites excluding 4 confirmed sites.
