12.3.1 Chi-Chi Township and the 1999 Chi-Chi Earthquake in Taiwan
Chi-Chi Township (shown in Fig. 12.4) is located in Nantou County in the central part of Taiwan. Early in the twentieth century during Japanese colonial rule, it prospered as a center of traffic, commerce, and politics. This was largely due to the building of the Chi-Chi railroad, the construction of the city hall, and a successful banana industry. The township currently has a population of approximately 12,000 across 11 villages.
The Chi-Chi Earthquake, with its epicenter near Chi-Chi, occurred on September 21, 1999 (see Chap. 6, the case of Christchurch earthquake and its population impact for comparison). It caused damage to more than 106,000 buildings and with an estimated 2500 casualties throughout Taiwan. In Chi-Chi itself, 1736 buildings were seriously damaged, 792 buildings were moderately damaged, and 42 people died. It was among one of the most serious disasters in the history of Chi-Chi (and Taiwan). It destroyed tourist attractions such as the traditional Japanese-style Chi-Chi station, historical temples, traditional pottery, and various important public facilities. These cultural resources, representing the area’s historically unique background, were significant elements in Chi-Chi’s economic and industrial recovery.
An event of personal significance occurred on October 1, 1999, ten days after the earthquake. My colleagues and I visited Chi-Chi to conduct a damage survey. It was my first field survey outside Japan and the town was littered with collapsed buildings (Fig. 12.5). Everywhere we looked, people were responding to emergencies. Because of its close proximity to the epicenter of the earthquake, the town had been devastated.
This time in Chi-Chi was relatively brief, but deeply affecting. It was a wonder how this town could ever recover. Just prior to this visit, I had finalized my doctoral thesis, “Study on Building Damage Estimation based on the Actual Damage Data due to the 1995 Hyogoken Nanbu Earthquake,” and was looking for the next research topic. As a researcher with a background in architecture and city planning, I became immediately interested in the post-earthquake recovery of Chi-Chi. This experience turned out to be the trigger for later post-disaster recovery research.
12.3.2 Continuous Surveys in Chi-Chi and Building Ties
At the beginning of 2000, the Research Committee on Urban Planning and Community Development for Disaster Reduction (the Committee) was established within the City Planning Institute of Japan (CPIJ). As member of the Committee, I met many young like-minded Japanese researchers and a Taiwanese student, Hsueh-Wen Wang, who were motivated to understand the process of urban recovery in Taiwan. The importance of on-site field surveys was advocated by this group who successfully gained CPIJ’s support.
As a delegate member of the Committee, I visited Chi-Chi again in April 2000, approximately six months after the earthquake and set about investigating recovery conditions in the township, as well as other affected areas in Nantou County and Taichung County. On this visit, we gathered materials and information on damage (walk through surveys, photo recording, interviews, and collecting data on housing stock) that would help in better understanding the recovery situation and the urban recovery strategies that were being developed and implemented.
Numerous stakeholders and specialists affected by the tragedy or involved in the recovery were engaged in the course of conducting the survey. The stakeholders included faculty members of the National Taiwan University and Feng-Chia University, government officials, NPO members in charge of rebuilding communities in the affected districts, architects, planners, and local residents. Among our many interactions, meetings with Prof. Liang-Chun Chen of the National Taiwan University were perhaps the most significant. They enabled us to maintain continuous contact with the Taiwanese recovery situation over a number of years. These important meetings were arranged by Ms. Wang, who played a critical role helping our study survey.
In April 2001, the Committee received a three-year research grant entitled A Comparative Study on Disaster Management and Reconstruction Strategy among Earthquake Disasters of Hanshin (Japan), Kocaeri (Turkey), and Chi-Chi (Taiwan), from the Japan Society for the Promotion of Science (JSPS). The 1999 Kocaeri Earthquake, also known as the 1999 Izmit Earthquake, occurred in Turkey on August 17 1999, approximately one month before the 1999 Chi-Chi Earthquake. Our intention was to compare the Kocaeri and Chi-Chi urban recovery processes to the 1995 Great Kobe (Hanshin) Earthquake recovery.
Supported by the grant, frequent visits were made to affected areas in Turkey, Taiwan, and Japan for surveys with particular research concerns and continued to collect related materials and information through to March 2004. The research covered a wide range of topics that included urban recovery planning, temporary housing, permanent housing (Fig. 12.6, left), construction methods, economic recovery, debris management, community building, childcare activities (Fig. 12.6, right), and more. Given that the field of post-disaster urban recovery research in at this time was still in its infancy, the interviews and discussions with local government officials and recovery specialists in Turkey and Taiwan were found to be extremely helpful in shaping our thoughts regarding what is needed to conduct an insightful comparative study of post-disaster urban recovery.
During this time, I visited Chi-Chi several more times meeting two key persons who would be instrumental in advancing my research. An Internet search for an interpreter who could translate from Chinese to English led us to Ms. Yayoi Mitsuda (Yoyo), a multilingual Japanese student who was studying cultural anthropology at National Tsing Hua University. It was my great fortune, for Yoyo became an indispensable partner in conducting surveys.
Random good fortune also led us to a restaurant owner in Chi-Chi referred here to as David. While out conducting field surveys, we stopped at David’s restaurant for dinner. It was a small, unassuming restaurant of the type we would often see along the streets of Taiwan. We quickly discovered that the restaurant operated as a community hub. It turned out that David was a community leader in Chi-Chi, with close relationships with the current and former mayors and other local people of influence. Since that first night, David’s restaurant became my base for conducting surveys in Chi-Chi. My time there yielded an exceptional amount of information on the recovery process, local history, key persons, politics, culture, human relationships, and much more.
Soon after the project ended in April 2004, I managed another JSPS grant to pursue research in Chi-Chi entitled Architecture of Reconstruction Process of Chi-Chi Area (Taiwan) and Archives Related to Urban Reconstruction in the World. This meant that the research ideas, which had been forming since my first days in Chi-Chi, would continue to develop and mature.
12.3.3 Research on Post-earthquake Recovery in Chi-Chi
My research activity in Chi-Chi went on until 2008. It allowed for continuous surveys and research activities over an extended ten year period, mostly in a trial-and-error fashion. This work is published in several academic journals (e.g., Murao 2006a, b, Murao et al. 2007) and international conference proceedings. Some of the research findings are described below.
Through the field surveys, I was able to monitor and record the urban recovery conditions of Chi-Chi, which were in a continuous state of change. In order to clearly understand Chi-Chi’s transition, a proper town map was necessary. In 2000–2001 however, such a map was difficult if not impossible to obtain. Consequently, I decided to create my own digital base map. Walking around and surveying the town with lab students using IKONOS (satellite) imagery, I continued to digitize the research area until a suitable GIS base map was completed. The map functioned to chronologically record the building demolition and reconstruction conditions that I had been monitoring since the earthquake struck. The recovery processes of Chi-Chi could be representable visually, as illustrated by the maps in Fig. 12.7.
Through the study of the Hanshin (Japan), Kocaeri (Turkey), and Chi-Chi (Taiwan) earthquake disasters and recoveries, I compared post-disaster urban recovery processes in cities with such different social backgrounds with my collaborators in Taiwan, Turkey, and Japan. Based on this cooperation experience, I recognized the need to develop a quantitative evaluation method but was yet to determine how to assess the recovery process quantitatively. This became an important research question during my time in Chi-Chi.
The question continued to taunt me, until one day, in a research meeting at the National Taiwan University, I was struck with the idea to represent the progress of the recovery by creating “recovery curves” based on building construction data. This process is essentially counting the number of building completions of various types over time. Later, with the support of Yoyo our translator and several officials, I was able to obtain statistical data on post-earthquake construction from the Nanto Government. From this data, I was able to create recovery curves for the various building types (temporary houses, rebuilt buildings, and new buildings) that are shown in Fig. 12.8.
The recovery curves show the reconstruction of buildings in Chi-Chi began approximately six months after the earthquake and continued for a further three years. The construction of new buildings began only after a delay of 1.5 years. This component of my research was challenging, but the method for constructing recovery curves would later be applied to good effect to my other research cases in Sri Lanka, Thailand, Indonesia, and the Japanese coastal areas affected by the 2011 Great East Japan Earthquake. The approach helped to conveniently compare recovery processes in areas affected by disasters in the four countries under study.
Having the opportunity to monitor the reconstruction process over an extended period and applying the idea of recovery curves contributed greatly to the research outcomes in Chi-Chi. It should be noted that while the research was carried out to understand Chi-Chi’s recovery process, in terms of changes in the area’s physical environment such as building reconstruction and the restoration of housing, we also recognized that the observable recovery was the product of human activity. Accordingly, I often sought out and interviewed key persons in the recovery effort. They included mayors, local government officials, shop owners, and victims. They were interviewed about Chi-Chi’s history and cultural background, the behavior of individuals from the initial emergency response stage to the reconstruction stage, and the various recovery strategies that were being employed. Based on the opinions and concerns expressed by residents in these interviews, I modeled the post-earthquake recovery process by using the simplified model shown in Fig. 12.9. This systematic model indicates the sequential process of recovery from the viewpoint of the victims, from the early catastrophic moments until the time of resettlement in permanent housing.
By 2006, I had monitored the ever-changing status of Chi-Chi Township and spoken extensively with local residents for several years. I began to consider the importance of producing a permanent record of Chi-Chi’s urban disaster recovery processes. By this time, I had already gathered a great number of pictures, movies, and considerable other data. From this, I conceived the idea of creating a digital model of Chi-Chi Township to preserve at least a segment of the recovery process. To this end, together with my laboratory students, I took pictures of every building elevation in the area and ultimately completed the model called Digital Chi-Chi City on the Google Earth platform. With information on the recovery conditions of important facilities in the township, Fig. 12.10 illustrates the product of our efforts.
12.3.4 Lessons from Post-earthquake Recovery in Chi-Chi
The Chi-Chi experience provided a number of important lessons regarding long-term post-disaster research in foreign countries. From the first visit to Chi-Chi in 1999, it was clear that the support of others was needed to conduct effective surveys and reach useful research outcomes. The support of Prof. Liang-Chun Chen, David, and Yoyo was crucial. The following describes their contributions as a way of underlining the importance of finding reliable local collaborators when conducting international disaster research.

Seek out collaborative relationships with local specialists/researchers
I first met Prof. Lian-Chun Chen (2001) at the National Taiwan University during the course of developing my survey for the Comparative Study on Disaster Management and Reconstruction Strategy among Earthquake Disasters of Hanshin (Japan), Kocaeri (Turkey), and Chi-Chi (Taiwan). Prof. Chen graduated from Waseda University in Japan, which made it easy for us to communicate about the survey’s purpose and subsequent information requests. Following our first meeting, we had many more opportunities to exchange information and ideas on the recovery in Taiwan. Prof. Chen generously provided all requested information.
Under the 2004 JSPS grant Architecture of Reconstruction Process of Chi-Chi Area (Taiwan) and Archives Related to Urban Reconstruction in the World and with the support of Prof. Chen, I spent three months in Taiwan (primarily in Chi-Chi) during the summer of 2005 as a visiting researcher at the Graduate Institute of Building and Planning, National Taiwan University. Throughout this time, Prof. Chen was available to answer questions about the cities, building structures, or disaster management systems of Taiwan. He would introduce helpful faculty members and suggest suitable paths for this research.
His invaluable assistance made me realize that when traveling to affected areas after a disaster, and especially in the field of urban recovery, it is difficult for foreigners to successfully conduct field surveys using suitable research questions without solid knowledge of the social context. Thus, it is extremely important to have a specialist or local researcher in the same research field who can provide critical support.

Be a friend and build good relationships with the local community
Whenever I returned to Chi-Chi, David’s restaurant was always the first place I visited. There I would have dinner and get the latest information on Chi-Chi Township, the recovery situation, politics, the new mayor, new restaurants, business conditions, visitors to Chi-Chi, and the current circumstances of individual residents. Because of his numerous connections, I was able to conduct interviews with many of the local people, which would eventually lead to my structural model of the post-earthquake recovery process (Murao 2006b). His contacts opened the door to much of the data and materials needed in this research.
As noted earlier, meeting David was by sheer accident, yet he became precious to my research. It was important to continue to visit David’s restaurant, particularly in the early stages of my long-term work in Chi-Chi. With each visit, exchanging stories about our families and ourselves, drinking together, or singing loudly brought our relationship closer. The rapport that we built led David to introduce me to many of Chi-Chi’s stakeholders and played a key role in my ability to finalize my research there.
When a disaster occurs, the temptation for disaster recovery researchers is to immediately survey those affected by the tragedy. However, essential information for comprehensive recovery research, including knowledge of the social context, cannot be acquired without taking the time to establish a strong rapport with the local people.

Find the best partner possible
Yoyo was a doctoral student at the Institute of Anthropology, Tsing Hua University, who was conducting research on the survival strategies of the Thao people living near Sun Moon Lake in Nantou County, Taiwan. She became critical to my research in Chi-Chi. I have an engineering background with a focus on architecture and city planning. However, post-disaster urban recovery activities are, in a sense, comprehensive phenomena of society as a whole. Given this conception, I intended to take an interdisciplinary approach to my research in Chi-Chi—an approach that included sociology and anthropology. Yoyo fully understood my intention and advised me on the most appropriate ways to conduct my local surveys.
In her capacity as interpreter, noting that I cannot speak or understand Chinese, Yoyo would often pose more questions to the interviewee than I had requested in order to gather the kind of information that she knew I needed. This ability arose from her sense of anthropology and intimate knowledge of society in central Taiwan, as well as her deep understanding of my long-term research goals. As a young anthropologist whose doctoral thesis focused on the indigenous people of Taiwan, Yoyo’s complementary knowledge and instincts were indispensable to my work. I met her in 2002 quite by accident, but the successful outcomes of my research could not have been produced without her advice and support.
I can easily say, no one could replace her. Good research in overseas fields can sometimes come down to one happy chance encounter. Such continuous surveys are basic activities to obtain proper datasets for the demography of disasters.
