Dr. Chun-Hsiang Kuo works in the field of engineering seismology, with a research focus on strong ground motion and site effect. I obtained a PhD. degree from the Institute of Geophysics, National Central University (NCU) in Taiwan in 2009. In the same year, I started to work for the National Center for Research on Earthquake Engineering (NCREE). I was promoted to Research Fellow in 2017. I moved to the Department of Earth Sciences, NCU, in August 2020 as an Assistant Professor. The E-DREaM invited me as a Jointly Appointed Assistant Professor because of my knowledge and experience in engineering seismology. The NCREE invited me as an Adjunct Research Fellow. I was also an Adjunct Research Fellow of the Eastern Taiwan Earthquake Center (E-TEC) from 2020 to 2023. I was promoted to Associate Professor in 2023. 

About the research, a measured-based result on site conditions (Vs30) for the free-field stations of Taiwan Strong Motion Instrumentation Program (TSMIP) was proposed (Kuo et al. 2012), and the Engineering Geological Database for TSMIP (http://egdt.ncree.org.tw/) was also opened to the public. This result largely improved our understanding of the seismic site conditions in different regions of Taiwan and further enhanced the accuracy of strong motion prediction. We, as a team, also use microtremor measurements to study site effects and shallow velocity structures for the whole of Taiwan (Lin et al. 2009; Kuo et al. 2009; Kuo et al. 2015; Kuo et al. 2016; Chen et al. 2022). From 2015 to 2018, I joined an SSHAC Level 3 project in Taiwan and further developed a comprehensive site database, including various site parameters (Vs30, Z1.0, and Kappa) for free-field TSMIP stations for the advanced PSHA analysis (Kuo et al. 2017; Lin et al. 2018). A Database of Near-Fault Strong Motions with Pulse-like Velocity (http://nfpv.ncree.org.tw/) was announced in 2019 (Kuo et al. 2019), including global and Taiwan near-fault pulse-like strong motion time histories. It has been used by many professors and engineers from NCREE and several other universities in Taiwan and other countries for studies of building or structure response when suffering near-fault pulse-like ground motions. Strong near-fault velocity pulses were observed during the 6 February 2018, Hualine, Taiwan earthquake. Several studies tried to analyze the characteristics of those velocity pulses, as well as the impact on buildings and seismic damage (Kuo et al. 2019; Ji et al. 2019; Yamada et al. 2020; Lin et al. 2020; Wang et al. 2021). We studied soil nonlinear site response behavior using observed data of the regional SMART-1 array (Kuo et al. 2021) and the TSMIP network in the whole of Taiwan (Chao et al. 2023). A generic rock seismic velocity profile for Taiwan has been announced (Kuo and Abrahamson 2023), helping to understand the regional difference of ground motion characteristics between Taiwan and the Western US. As a team member of the Fault Displacement Hazard Initiative (FDHI) program executed by UCLA, we recently published a paper on a new fault displacement model (Moss et al. 2024, in press). I am also a member of a Taiwan regional GMM team under the NGA-West 3 project. 

研究室簡介

　　郭俊翔博士主要從事工程地震學領域的研究工作，研究重點為強地動和場址效應。他於2009年獲得國立中央大學地球物理研究所博士學位，同年進入國家地震工程研究中心（NCREE）工作，並在2017年晉升為研究員。2020年8月，他轉任國立中央大學地球科學系助理教授。由於他在地震工程學方面的知識和經驗，他被地震災害鏈風險評估及管理研究中心（E-DREaM）聘為合聘助理教授，同時也擔任國家地震工程研究中心的兼任研究員。2020年至2023年期間，他也是台灣東部地震研究中心（E-TEC）的兼任研究員，並於2023年晉升為副教授。

關於研究方面，其研究團隊針對台灣強震觀測網（TSMIP）的測站，提出了基於實測的場址條件（Vs30）結果（Kuo et al. 2012），並對公眾開放了台灣強震觀測網工程地質資料庫（EGDT）（http://egdt.ncree.org.tw/）。這項成果大大增進了我們對台灣不同地區地震場址條件的理解，並進一步提升了強地動預測的準確性。

他的團隊也利用微地動量測，研究全台灣的場址效應和淺層速度構造（Lin et al. 2009; Kuo et al. 2009; Kuo et al. 2015; Kuo et al. 2016; Chen et al. 2022）。從2015年到2018年，郭博士參與了一項在台灣的SSHAC Level 3計畫，並為TSMIP自由場測站進一步開發了一個全面的場址資料庫，其中包括各種場址參數（Vs30、Z1.0和Kappa），用於進階的機率式地震危害度分析（PSHA）（Kuo et al. 2017; Lin et al. 2018）。

2019年，近斷層脈衝型地震動資料庫（http://nfpv.ncree.org.tw/）正式發布（Kuo et al. 2019），收錄了全球和台灣的近斷層脈衝型強地動時程資料。該資料庫已被台灣及其他國家的多所大學教授和工程師用於研究建築物或結構物在遭受近斷層脈衝型地動時的反應。

在2018年2月6日的花蓮地震中，觀測到了強烈的近斷層速度脈衝。我們發表了多項研究試圖分析這些速度脈衝的特徵，以及它們對建築物和地震損害的影響（Kuo et al. 2019; Ji et al. 2019; Yamada et al. 2020; Lin et al. 2020; Wang et al. 2021）。郭博士團隊利用區域性SMART-1陣列（Kuo et al. 2021）和全台灣的TSMIP觀測網的觀測資料，研究了土壤的非線性場址反應行為（Chao et al. 2023）。

近年來我們發布了台灣的通用岩盤波速剖面（Kuo and Abrahamson 2023），有助於了解台灣與美國加州之間地動特徵的區域差異。郭博士身為由加州大學洛杉磯分校（UCLA）執行的「斷層位移危害度計畫（FDHI）」的研究成員之一，其團隊近期發表了一篇關於新斷層位移模型的論文（Moss et al. 2024, in press）。目前也是NGA-W3所屬台灣區域模型研究小組成員之一。
