  • Geodetic Investigation of the 2018 Mw 6.4 Hualien Earthquake in Taiwan
    Geodetic Investigation of the 2018 Mw 6.4 Hualien Earthquake in Taiwan James Chen 11/21/2018 Advisor: Mong-Han Huang GEOL 394 Abstract: A Mw 6.4 Hualien earthquake occurred on Feb 6th 2018, illuminating the local ​ geologic features in the Hualien area. In the coseismic analysis, a three-fault system is required to explain both seismic and geodetic data. This system is composed of a EW striking south dipping fault in the north where the slip initiated. The slip then transferred to a 37 km long west dipping fault located from east of the Milun tableland to west of the north Coastal Range, and finally to a ~8 km long east dipping Milun fault at shallower depth splitting the Milun tableland. In this study, a four month long postseismic surface displacement of the 2018 Hualien earthquake is measured using synthetic aperture radar interferometry (InSAR) and GPS time series. Postseismic displacement during the first four months indicates a cumulative 3-6 cm displacement in the central part of the Milun fault. The four month postseismic time series analysis shows that the area in the north Milun tableland is slowly uplifting, whereas the southeast part of the tableland is subsiding indicating the presence of a curved fault scarp in agreement with the fault trace suggested previously. However, there is minute surface displacement above the main west dipping fault plane west of the north Coastal Range. The lack of postseismic displacement near the north Coastal Range indicates small or deeper afterslip that cannot be detected by InSAR, and the rapid postseismic displacement along the Milun fault implies afterslip along the fault at shallow depth.

The Richter magnitude (ML) of the earthquake was 6.26 and the seismic intensity ranged up to level VII, the strongest seismic intensity level regulated in Taiwan. Almost all the major damage resulting from this seismic event was occurred near both sides of the Milun Fault, where records from nearby strong motion stations dis- played the characteristics of near-fault ground motions. The main seismic damage was the collapse of four buildings with soft bottom stories, one of which resulted in fourteen of the seventeen total fatalities. Comparing the acceleration response spectra with the design response spectra sheds light on the efects of near-fault ground motions on the collapsed buildings. Based on the eventual forms of collapsed buildings, building collapses that have generally led to major casualties in past seismic events around the world can be classifed into sit-down, knee-down and lie-down types.

  • Corporate Citizenship Activities Report Fiscal 2018
    Corporate Citizenship Activities Report Fiscal 2018 On Publishing the Corporate Citizenship Activities Report Fiscal 2018 The Kao Group has maintained activities with the theme of "creating an environment and developing human resources to nurture the next generation," in order to realize the satisfaction and enrichment of people's lives, based on the Kao Way, our corporate philosophy. Since 2012 we have emphasized the three key areas of the Environment, Education and Community to support the social foundation as a corporate citizen implementing activities to contribute to building a better society. Meanwhile, in addition to carrying out corporate citizenship activities that help create a sound society, expectations have been rising in recent years for efforts that contribute to society through business. In response, Kao established a new ESG (Environmental, Social and Corporate Governance) Division in July 2018. Our aim is to capture ethical trends in society and among consumers to bring about sustainable business growth and social development with a long-term outlook. Kao believes in the importance of integrating corporate citizenship activities with the contributions made to society through business, and moving ahead by aligning the two in a unified direction. Kao Group holds "Kirei – Making Life Beautiful" as a key concept, and the thoughts and beliefs incorporated in this message are shared throughout the Group to promote concrete initiatives. Through activities unique to Kao that embody the concept of "kirei," we aim to contribute to resolving global-scale social issues and building social sustainability. It is our belief that these efforts will ultimately result in improved corporate worth. This report reviews the corporate citizenship activities conducted in FY 2018 and summarizes the main activities, including those at Kao Group worksites and companies within and outside Japan.

Vidale Former Director, Southern California Earthquake Center, University of Southern California, USA This talk reviews new ideas about earthquakes that we’ve learned at the Southern California Earthquake Center (SCEC), and where we’re headed next. The danger and cost of earthquakes has focused public fear and research effort in California since long before the devastating 1906 San Francisco and 1933 Long Beach events. Precise earthquake prediction, heralded as imminent in the 1970s, has faltered, maybe permanently, but nevertheless there is progress. Hosted at USC, with 16 core institutions and more than 60 affiliated organizations, SCEC involves more than 1000 quake cognoscenti. Funding comes from the National Science Foundation, the United States Geological Survey, and special projects with foundation and corporate partners. We are uncloaking the mysteries in plate tectonics, the San Andreas fault system, and how the ground is driven to shake. SCEC investigates all aspects of earthquakes from theoretical models through detailed observations to hazard maps. We foster collaboration among the fields of science and engineering research, computer science, communication and outreach to develop integrated research products used by various stakeholders. The central point of this intense research, and the result that most directly benefits those living in California, is the improvement of maps of earthquake danger.
