Day_180: The Aftermath of “Natural” Disasters: Long-term Effects

The enduring consequences of natural disasters can be equally as catastrophic as their immediate repercussions. They frequently result in economic instability, social turmoil, and environmental destruction. Furthermore, they have the potential to establish a harmful cycle of destitution and susceptibility, particularly in developing countries.

For example, the act of demolishing infrastructure has the potential to interrupt vital services, including healthcare, education, and transportation. These consequences can have extensive effects on the progress of social and economic development, impeding endeavors to alleviate poverty and enhance living conditions.

<The Impact of Natural Disasters on Global Economies>

Natural disasters exert a substantial influence on global economics. They have the potential to inflict substantial financial losses, interrupt the flow of goods and services, and impede economic progress. Furthermore, they have the potential to worsen economic disparities, as individuals with few means are frequently the most severely affected.

As an illustration, the earthquake and tsunami that occurred in Japan in 2011 resulted in around $360 billion in losses, establishing it as the most expensive natural catastrophe in recorded history. The occurrence additionally prompted a nuclear catastrophe, exacerbating the economic and societal repercussions.

Day_136 : Disaster-Related Death (1)

Kobe Earthquake : 919 (22Dec.2015)
Great East Japan Earthquake and Tsunami : 3,472 (31Mar.2016)

What are the numbers?

The above numbers are the numbers of disaster-related deaths. The disaster-related death means the death which is not directly caused by hazards such as sickness, disease, and committing suicide. Especially , the disaster-related death number of GEJET is still increasing even 5 years after the disaster. This reflects aging society. The elderly people tends to have sickness and losing hope without family members. Local governments have been working hard to prevent such tragedies. They are visiting and watching the victims individually.

Day_123 : 1995 Kobe Earthquake victims (2)- Golden 72 hours

Day_76 gave you the following two inquiries on the 1995 Kobe earthquake.
1) Why were so many early 20’s victimized?
2) Which floor is more dangerous, 1st or 2nd?

Day_76 : 1995 Kobe Earthquake victims

The next question is what can you say about the following Figure 1?

rescue
Figure 1  Search & Rescue Operation Statistics

You can see the survival rate dramatically dropped after the 3 days, 72 hours. The experts say this 72 hours after the disaster, especially earthquake, is golden 72 hours. This is a well-known phrase even before the Kobe earthquake.

Day_122 : Japanese Disaster History after the Second World War (2)

Japanese disaster history has three turning points. The first is the Typhoon Isewan (Vera) in 1959. The second is the Kobe earthquake disaster in 1995, the third is the Great East Japan Earthquake and Tsunami (GEJET) disaster in 2011(Day_33).

Day_33 : Japanese Disaster History after the Second World War

You can see the following figure 1 which displays the dead and missing numbers caused by natural disasters in Japan.

deathtollafterww2
Figure 1 The dead and missing numbers caused by natural disasters in Japan

After the second world war, Japan was vulnerable, so we had a lot of natural disasters, especially Typhoon disasters from 1945 to 1959. We call this 15 years a great flood and storm era. The first hit was Typhoon Makurazaki on Sep. 1945.The typhoon disrupted Hiroshima city. There were 1229 casualties in the city. This fact reminds us what happened in Hiroshima in the same year (Day_34(Re)).

Day_34 (rev): The meanings of the Typhoon Makurazaki in 1945

The Isewan Typhoon has the following aspects: 1) Physical damages were tremendous 2) Lack of consideration of disaster prevention 3) Inadequate flood defense system 4) Inadequate warning and evacuation system ( The details will be explained later) After the Typhoon Isewan, disaster countermeasures basic act was enacted in 1961. The act combined many disasters related laws into one. After the Isewan Typhoon, we Japanese had thought we were successfully mitigating natural disasters.  You can see the dead and missing numbers were dropped right after the Isewan Typhoon by Figure 1.  This is mainly because of infrastructures and the development of science and technologies such as warning systems along with Japanese rapid economic growth. In addition, we had, fortunately, no huge natural hazards until the Kobe earthquake in 1995.

After the period of1960-1994, we have faced the Kobe Earthquake in 1995. Then, we realized that we could not prevent natural disasters, however, we could mitigate natural disasters after the earthquake. We also learned the importance of soft countermeasures as well as hard countermeasures. The Japanese Government had changed the policies again. The Kobe earthquake facilitated volunteer activities. Many social scientists started to investigate disasters. Before the disaster, natural scientists and engineers are the main players to do disaster-related research along with Japanese infrastructure centered policies. After that, we had confidence again and we thought we could be a model for other countries. The World Conference on Disaster Reduction was held in Kobe in 2005. Kobe city tried to be a center of world disaster-related organizations. (This Kobe earthquake disaster will be explained later)

However, we faced the Great East Japan Earthquake and Tsunami (GEJET) disaster in 2011. The GEJET disaster became the worst ever disaster in Japan after the second world war. The GEJET broke the Japanese confidence again and reconsider our strategies.

Day_111 : Earthquake Information (1)

Introduce you two earthquake information websites. 1) The Earthquake Track 2) J-RISQ

1) The Earthquake Track

The Earthquake Track is useful to overview the earthquake occurrence situation in the world (Figure 1). As you can see in the below figure, every day’s earthquake occurrence situation such as how many times the earthquake occurred, what is the biggest earthquake of the day, and the earthquake locations on the map can be seen. Also, we can access to the detailed information of the quakes.

160831_earthquakepic1
Figure 1  The Earthquake Track

2) J-RISQ

Figure 2 shows J-RISQ provided by the National Research Institute for Earth Science and Disaster Prevention (NIED).

160831_JRISQ1
Figure 2  J-RISQ website

As you can see the Figure 2, this site does not only provide earthquake (hazard) information but also affected population estimation (exposure). In addition, the site gives us historical information of the affected area. You can also refer prediction data on the map such as earthquake distribution of 2% probability of exceedance in 50 years and distribution of return period of 50,000-year.

Day_104 : Lessons from a Japanese Environmental Movement- The Matsumura Research Group (2)

Mishima Numazu Shimizu (MNS) environmental movement in 1963-1964 is the turning point of a Japanese environmental history. The core of the movement is the science-based issues, especially, The Environmental Impact Assessment conducted by the Government Research Group and the Local Research Group.

Day_96 : Lessons from a Japanese Environmental Movement- The Matsumura Research Group (1)

Proposed the Development Plan

The below Figure 1 and Table 1 indicate the proposed development plan. These are the companies which had planned to come to the area. You can also see the scale of the plan.

planned project MNS
Figure 1  Proposed an Industrial Complex Plan

Table 1 The Scale of the Plan

The planned MNS

What is the MNS Movement?
The following two factors can be highlighted to explain the MNS movement. The first, the survey carried out by students (KOINOBORI research). The second, a few hundred education programs (mainly for local citizens)

In regard to the student survey, the survey carried out by students of Numazu Technical High School consists of three types by using local materials which were KOINOBORI, empty bottles and thermometers. The KOINOBORI were used in the air current survey that was conducted by about 300 students. The students made some air current maps that showed that the government’s appraisal of wind direction was incorrect. These maps gave decisive data to the Matsumura research group. Empty bottles were used for the water current survey. Thermometers enabled the students to make some maps showing the variation of temperatures.

On the other hand, the results of the survey reported by students of East Numazu High School which were called “Petrochemical Complex Project in Numazu and Mishima Area” was conducted by a Local Research Club. They researched it by using social scientific methods (including the survey in Yokkaichi City). The MNS activists use this report.

With reference to the education programs, many education programs were conducted by Numazu Technical High School teachers. They were held at schools, at the town halls and in the streets. Because of the programs, local citizens (including farmers and fishermen) became eager to learn. Local citizens wanted to know what was going on in their locality.

The Students Participatory Survey

The following Figure 2  shows the wind directions are from the sea to the land. This map was created by the students during the Koinobori time. This means the local people would be influenced by the pollutions from the planned factories. However, the government survey appealed the different ways.

The Kurokawa Research Group (Gov. Research group) carried out the first largest ever Environmental Impact Assessment (EIA) by the Japanese government in 1964. The representative was Dr.Masatake Kurokawa and the staff consisted of national academics. The budget was about 20 million yen (about 180,000 USD) at that time. The research was carried out by using helicopters and high-tech machines. The Kurokawa Research Group was nominated by the Minister of International Trade and Industry and the Minister of Public Health.

On the other hand, the Matsumura Research Group carried out the EIA by getting the cooperation of local people, including high school students. The representative was Dr.Seiji Matsumura and the staff consisted of two researchers with international experience and local high school teachers (Table 2). The budget was about 100 thousand yen (about 900 USD) at that time. The research was conducted using readily available materials and low-tech manpower (for example, Koinobori research). It meant that research people, as well as the local people and high school students, used their own ideas. The Matsumura research group was nominated by the Mayor of Mishima city, Mr.Taizo Hasegawa. They use students, local materials, and Japanese culture.

Table 2 Matsumura Research Group

* I have life stories about them by interview surveys

The Formation of the Matsumura Research Group

The following is the formation process of the Matsumura Research Group. The National Institute and the Local high school have bonded together. These make ‘Think globally, act locally’.

  1. Education Seminar about Pollution Held by Two High School Teachers and a Professor
  2. Explanation of the Estimated Pollution Levels Given to the NIG (National Institute of Genetics) by Mr.Nagaoka and Mr.Nishioka (Teachers)
  3. Decided by the NIG Members to Refuse the Petrochemical Complex Plan
  4. Advice Given to Mishima City’s Mayor (Hasegawa) from the NIG Members to Establish the Research Committee for EIA
  5. Decision by Hasegawa to Reject the Proposed Petrochemical Complex
  6. Acceptance of Numazu Technical High School and NIG to do EIA in the Area

To be continued.

Day_99 : A Secondary Disaster- 1972 Shigeto Landslide Disaster

The Shigeto ward, Tosayamada town in Kochi prefecture had a huge landslide disaster on the 5th of July in 1972. We call it Shigeto Landslide.

What we can learn from this landslide is the secondary disaster.

First, a small landslide occurred at 6 am on the day. One volunteer firefighter was buried alive by the landslide. Other volunteer firefighters and local people started to conduct rescue work for him.

Second, a huge landslide happened at 10:55 am during their tasks and killed 59 among them. In addition, the landslide pushed the train stayed at Shigeto station away.

The following Figure 1 shows the landslide (NIED DIL)
