Submarine cabled real time observation and digital twin of tectonic plate boundary - The future of earthquake and tsunami prediction
Around the Japan islands, the mega thrust earthquakes occur at the plate boundary under the seafloor frequently at a cycle of about 100 to 150 years. This event could trigger a tsunami that could cause significant damage to coastal areas. The collection of seismic activity information in the seafloor is very important in terms of improving the accuracy of hypocenter determination and the grasp of micro-seismic activity, and observing this information in real time is essential for improving the early warning performance in the event of an earthquake. From this point of view, the establishment of real-time observation technology of the seafloor has been desired. In the 21st century, the development of the seafloor observatory, which is based on the technology for telecommunication submarine cable, has progressed and several systems are currently operating worldwide. In addition, it has become possible to implement a variety of precise measurement technique on the seafloor by improving the workability of the seafloor using ROV. The goal of the disaster countermeasures is not only for its early warning also its prediction, To reach the goal, it is essential to acquire the data real-time and to accumulate the data over a long period of time, in addition to the sophistication of computer simulation technology to realize the data assimilation (This is called “Digital Twin”). This presentation introduces the technical contents related to the submarine cabled observatory DONET constructed in the Nankai trough JAPAN and the approach of various computer simulation which is done to realize the prediction of future mega thrust earthquake disaster.
Katsuyoshi KAWAGUCHI was born in Tokyo, Japan, in 1964. He received the B.E. degree in ocean engineering, the M.S. degree in marine science, and the Ph.D. degree in marine science from Tokai University, Tokyo, Japan, in 1987, 1989, and 1993, respectively. From 1993 to 1995, he was a Lecturer at the Department of Marine Mineral Resources, Tokai University. Between 1995 and 1996, he worked at the Mechanical Engineering Department, University of Hawaii, Honolulu, HI, USA, as a Postdoctoral Research staff. From 1996 to 1998, he was a Postdoctoral Researcher at the Deep-Sea Research Department, Japan Marine Science and Technology Center, Yokosuka, Japan. In 1998, he had a tenure researcher track at the Japan Marine Science and Technology Center [currently the Japan Agency for Marine-Earth Science and Technology (JAMSEC)] and became a Principal Research Scientist in 2008. Between 2008 to 2017 he has been directing the technology development group, R&D Center for Earthquake and Tsunami and served as deputy director in 2016-2017. From January 2018, He was appointed Director-General of Marine Technology and Engineering Center (MARITEC). He also acts as a visiting professor at Tokai University and the Institute of Industrial Science, University of Tokyo (Tokyo, Japan), and the chairman of the IEEE Oceanic Engineering Society (OES) Japan Chapter. His research background is underwater robotics (hardware and software design, and control) and real-time seafloor observation system and its applications.

Making the weather and ocean data ecosystem through the public-private engagement
In most of the Asia country, Open is NOT the traditional culture. The data mean the knowledge and privileged by bureaucracy, limited Politian awared about that due to lack of Law, policy and education. Most of the important decisions are made by state officials rather than by the data governance with the public-private engagement. We hope to mention the core problem and identify the priority to make the ecosystem. Ex.Weather and Ocean Science data is not the secret or national security issues, the open platform to gathering data and information are the key to make progress. We hope to share the experience and guidance of Asia and other countries to find a better and more targeted policy guidance.
Chi-Ming Peng is the founder and CEO of WeatherRisk Explore, Inc., and an Adjunct Professor in the Department of Atmospheric Science in the National Central University and the Chinese Culture University in Taiwan. To fulfill his mission as an atmospheric scientist, he has outreached to broadcast weather and climate-related issues as a program host in Broadcasting Corporation of China (Taiwan) and a weather anchor in DaAi Television. In 2016, Dr. Peng was invited by Yahoo TV! for a popular live show. As an atmospheric scientist, he has worked as a program host in the Broadcasting Corporation of China (Taiwan) and a weather anchor in DaAi Television, broadcasting weather and climate-related issues. Furthermore, in 2016, Yahoo TV recruited Dr. Peng as the most popular OTT program in Taiwan. Dr. Peng is also a member of an international community of weather anchors initiated by WMO, and Climate Without Borders. Beyond meteorology, he has also worked in climate change adaptation, mitigation, disaster prevention and reduction, emergency management, atmospheric chemistry, and science communication. In May 2013, WeatherRisk was accredited by UNISDR as an official private sector partner. Cooperating with businesses all over the world, WeatherRisk has contributed to database integration and national/regional disaster risk assessment. As a long-time volunteer of the Tzu Chi Foundation, Dr. Peng has helped to raise public awareness in climate change. As one of Tzu Chi's delegates, he has participated in UNFCCC COP since 2012. With his experience in dealing with climate data, Dr. Peng serves as the president of Taiwan Open Data Alliance, which promotes the transparency of government resources in public-private partnerships. Dr. Peng got the Taiwan Outstanding I.T. Elite Awards in 2017.

Underwater technology and the solid-earth science: bypassing the ocean
The Earth locks its secrets beneath the surface, whereas scientists strive to extract them with different tools overcoming all kinds of difficulties. Geologists traditionally have to climb the mountain to collect rocks; geophysicists install seismic sensors on the ground in remote areas to receive faint signals from the deep; new generations of scientists fly a drone to photo the landscapes prone to a catastrophic landslide. However, no matter how well observational technology has served us on land, the utmost hindrance for a full understanding of the planet’s hidden inside, where all forces join to produce mountains, earthquakes, volcanoes, and tsunamis, is always the ocean, which covers 3/4 of the earth’s surface. An un-biased illumination of the planet’s inner working, to the surprise of many, relies on the UT. In this talk, I summarize the tight connection between UT and solid earth, and elaborate on how the advance in the former has promoted researches in the latter, and vice versa. Because Taiwan is a famous natural laboratory for earth science, part of the examples are drawn from the recent UT-science development in this country.
Ban-Yuan Kuo graduated from the Institute of Oceanography, National Taiwan University in 1983, received his PhD degree from Brown University in 1987, and joined the Institute of Earth Sciences (IES), Academia Sinica, Taiwan in 1989. He was trained as a seismologist with a wide interest spectrum targeting prominent earth science problems in different regions: from dynamics and magmatism of subduction zones to structures of deep earth; from mountain building processes in Taiwan to continental collision/subduction in the Hindu Kush and Pamir. In 2002, he launched a project in IES aimed at expanding the land-based seismic network to the ocean, and has since dedicated to developing ocean-bottom seismometers in collaboration with the major underwater technology institutes in Taiwan such as TORI and IUT-NSYSU. This science-underwater technology endeavor has sparked a new wave of technological advancement in Taiwan that is designed to drive the science forward in a more sustainable way than in the past. In recent years, he is leading the joint projects on ocean-bottom seismometer experiments with the JAMSTEC and the University of Tokyo. His long time collaborators also include scientists in WHOI and LDEO.
