Day_148: The World Largest Disaster Links

Below is the disaster links site which was created a long time ago. I will renew this site step by step. In addition, some are still only in Japanese and original disaster-related pictures are omitted, so I will consider these also.


The below disaster-related world organization’s link site is the one which was built when I was working at NIED DIL and still working as one of the products there. I am very happy to know that but I would like to renew this also to contribute to the institute with my gratitude in the near future, I hope.


Day_144 : Disaster Information 4


The update of some useful disaster information websites are as follows:

Flood list: an excellent source of flood disasters


AHA center- adinet: disasters in ASEAN countries can be browsed and also checked in detail.


DRH-Asia: cases on local knowledge and their applications related to the technologies in Asian countries can be found.


The post of the disaster information 3 is the followings:

Day_69(rev) : Disaster Information 3


Introduced you the following disaster information.
1) General info. 2) Database 3) Update info

1) General info is the first website to check.


2) Database is the base to analyze the target disasters.


2. Desinventar


The disinventar is very accurate and detailed, however, the listed
countries are limited.

3) Update info. Is the website, we can check on a daily basis.
These are also useful to overview of the recent disasters.
1. ReliefWeb








Concerning, data on demographic, socioeconomic, and others, we should
clarify the levels from national to local.

County Level
1. UN data


2. World Bank open data

world bank data

3. CIA world factbook

world fact book

Provincial (States) Level
1. Government Office (National Statistics Office,etc.)

Community Level
1. Local Government Office
When we investigate the disasters, we firstly go to the ADRC (if the country is Asia) and Relief Web to see some significant numbers such as the death toll and affected numbers. Then, check the disaster history of the target areas by EM-DAT and Desinventar (if the country is listed). We also overview the county’s background by CIA world fact book and check some socio-economic data by UN or World bank open data. In addition, the local government or community data of the target area are significant to be accessed. These are the primary action to grasp the whole picture of the disaster.

Day_140 : Natural Disasters in Europe (2) Vajont Dam Collapse

Figure   The Europe

Concerning hydrological, meteorological, and climatological disasters, heavy rain, and storm disasters are caused by a low  pressure in the Iceland area developed in a winter season. A cold atmospheric current coming from Arctic gain a warmer vapor stream from the Gulf Stream and develop the strong atmospheric depression in the area. This causes the strong winds and high tidal waves along the coastal areas of the North Sea. Netherlands and England can be highlighted. Netherlands had storm surges in 1530 and 1570. The death toll were approximately 400,000(1530) and 70,000(1570) for each. The 1953 depression made 1800 death toll. This disaster reached to England also. England’s disasters were the 1703 Thames river flood and the 2003 Heatwave. The temperature was 8-10 over than an average year on August 2003 (Day_38).

Danube, Elbe, Rhine, and Seine rivers are on the gentle slope make slow inundations caused by heavy rains. On August 2002, the Central Europe had a heavy rain, this makes Danube and Elbe rivers overflows in Germany, Czech, Austria, and Hungary. The death toll is approximately 100, affected is over 100,000. Historical Buildings in the city such as Prague,Dresden, and so on along the rivers were also inundated.

Alps mountains have had landslides, debris flows, slope failures, and so on. The particular example is the landslide in Dolomites, North Italy in 1963. Overflows from Vajont dam caused by large-scale landslide attacked the village in downstream ares.The death toll is approximately 2600.

A brief explanation


An Interviews based explanation

On August 2003, the West Europe had 8-10 degrees celsius higher than the average. This heat wave killed 15000 in France, 7000 in Germany, 4000 in Spain, 4000 in Italy, and so on, totally 35000.

In summer 2010, Russia had a heat wave and this makes wildfire. The wildfire was spread out and it took over 1.5 months to extinguish.Many villages were destroyed by the fire. The Moscow was covered by harmful smoke. Over 55,000 were killed by the heat wave and the smoke in Russia.

Day_138 : Natural Disasters in Europe (1)

Natural disasters in Europe mainly consist of hydrological, meteorological, climatological, earthquake and volcano eruption disasters.

Figure   The Europe

Earthquake disasters mainly occur in the Aegean Sea, the south-western coast of Balkan Peninsula, and the southern part of Italy. Volcanoes are active in the central and southern parts of Italy, the southern Aegean Sea, and Iceland area.

Concerning hydrological, meteorological, and climatological disasters, heavy rain, and storm disasters are caused by a low  pressure in the Iceland area developed in a winter season. A cold atmospheric current coming from Arctic gain a warmer vapor stream from the Gulf Stream and develop the strong atmospheric depression in the area. This causes the strong winds and high tidal waves along the coastal areas of the North Sea.

Netherlands and England can be highlighted. Netherlands had storm surges in 1530 and 1570. The death toll were approximately 400,000(1530) and 70,000(1570) for each. The 1953 depression made 1800 death toll in 1953. This disaster reached to England also. England’s disasters were the 1703 Thames river flood and the 2003 Heatwave. The temperature was 8-10 over than an average year on August 2003.

With regard to earthquake disasters, Italy, Greece, and Portugal are the main countries to be affected.

The following past article explains the recent earthquake cases in Italy.

Day_137 : Aging Asia to Natural Disasters -Thailand(2)-

Day_68 indicates Thai population in 2012 was 64,460,000 and the proportion of those over 65 is 8.6 percent (11 percent in 2016) compared to 3.1 percent in 1970. This shows that Thailand is facing an aging society and the World Population Prospects* predicts this trend will accelerate. This situation is not exclusively in Thailand, but can likewise be viewed in almost all Asian nations. In addition, Asia is the most vulnerable in terms of natural disasters such as 7 of 10 of the deadliest natural disasters (1980-2014) took place in this region(Day_79). The World Bank mentions how Thailand faces the aging society from an economic development perspective, however, we also need to recognize this from a disaster reduction viewpoint. Okushiri island case can give us a significant insight(Day_75). This gives us a challenge of how disaster-resilient society can be established in the situation.

The World Bank notices**:
The Thai population is aging rapidly. The declining share of the working-age population will affect economic growth.
– As of 2016, 11% of the Thai population (about 7.5 million people) are 65 years or older, compared to 5% in 1995.
-By 2040, it is projected that 17 million Thais will be 65 years or older – more than a quarter of the population.
-Together with China, Thailand has the highest share of elderly people of any developing country in East Asia and Pacific.
-The primary driver of aging has been the steep decline in fertility rates, which fell from 6.1 in 1965 to 1.5 in 2015, as a result of rising incomes and education levels and the successful National Family Planning Program launched in 1970.
-The working-age population is expected to shrink by around 11% as a share of the total population between now and 2040 – from 49 million people to around 40.5 million people.
This decline in the working-age population is higher in Thailand than in all other developing East Asia and Pacific countries, including China.

Day_133 : Science, Technology, Population, and Lessons for DRR

Japanese people have tended to trust the government and science & technology so much.
These are one of what we learned from recent disasters. After the second world war, Japanese gov. has built high sea walls along the coastline especially potential risk areas all over Japan. We have also developed warning systems along with rapid economic growth. Not only those, but we have also developed soft countermeasures such as disaster education and training, especially after the 1995 Kobe Earthquake. After the Great East Japan Earthquake and Tsunami (GEJET) disaster, we have realized what has happened because of our over trust to the government and science&technology. This is why Japanese gov. has particularly focused on the community since the disaster, establishing a new frame on the community disaster planning in the disaster countermeasure basic act. The recovery plans on the affected coastal communities tended to change more integrated manners and so did disaster countermeasures than before, looks like turning back to the time when we did not have advanced science and technologies.

We need to know the limitations of the gov. and science&technology’s roles. We also can consider the demographic change to do the job for disaster risk reductions. For example, Japan is facing a severe aging society, so our government resources will be decreasing to cover the situations. We need to have more self-help and mutual help than public help.

Learning from the lessons and past wisdom with those considerations is also very important. “Inamura no Hi” is one of the important lessons we can learn from the past.

Day_88 : Inamura no Hi

“Inamura no Hi” is a story of a man who noticed a precursor of a large tsunami at the earliest stage and led village inhabitants to a higher ground by burning harvested rice sheaves. This story was based on a true story at the time of Ansei-Nankai Tsunami (1854), which claimed around 3,000 lives in the coastal areas of Western Japan (ADRC).

Hirokawa Town’s video well explains the background of the story in short and their tsunami disaster education.




Day_132_Area BCM (1)

In 2011, Great East Japan Earthquake and Tsunami (GEJET) disaster and the Chao Phraya River flood disaster made huge economic damages. They are in the top 10 costliest natural disasters (The very top and the 7th) in the world as you can see the following table.


Source: NatCatSERVICE/Munich RE 2016

From the historical point of views, the disaster trends from human sufferings to economic damages. The following figure shows the economic damage tendency is increasing with time and we can see the year of 2011 was an outstanding.


Source: EM-DAT

Especially, the globalization of the economic activities reflect these damages.In the event of large-scale disaster, a business sector is limited in its abilities to cope with disaster without the cooperative approach taken by the stakeholders of the public and private sectors in those areas.

With this situation, the concept of the Area Business Continuity Management (Area BCM) was revealed. This is a cooperative approach by those who wish to improve capacity for continuity and/or early recovery of business in their area in the event of disasters that affect the entire area(AHA CENTRE et al., 2015).

Day_125 : Shingen(-Zutsumi) Embarkment (2)

Those who can rule the water can also rule the country. This proverb became a reality, especially during the Sengoku period (Warring States Period) in Japan.

Day_85 : Shingen Embarkment

Shingen(-Zutsumi) embankment is a flood control system which was built over 400 years ago to protect the northern part of the Kofu Basin, the rich rice paddy areas of Kai Province. The name comes from the Daimyo (District Lord) Shingen Takeda. Shingen Takeda was one of the strongest Samurai Daimyo during the period. He controlled his soldiers well and so the floods.

shingenFigure: Shingen Embarkment**

In addition to Shingen-Zutsumi Embankment, there are also Bunroku-Zutsumi and Taiko-Zutsumi Embankments established by Shogun (Hideyoshi Toyotomi). The Circle Levee in Nobi Plain is also called that it was built during the time. However, there are still arguments that Samurai Daimyo could built such embankments or not because they required high technologies and a huge amount of human resources during the periods.

Day_115 : Disaster Technology Websites

Introduce you two disaster technology websites. One is DRH Asia-Disaster Reduction Hyperbase. The other is Global DRR Technology.

1) DRH Asia
This site provides the qualified information about DRR technology. We can grasp the contents so easily. This makes it possible to transfer the DRR technology. The contents are coming from many Asian countries and reviewed by experts. The challenge is limited contents number.

The following is the example of the contents.
Earthquake Early Warning and its Application to Mitigate Human and Social Damages (Figure 1)

Figure 1

We can understand the quality of the contents and availability.

2) Global DRR Technology
This site focuses on an online Community of Practice(CoP) in Disaster Risk Reduction(DRR). The contents volume is limited, however, the site can be checked easily. Especially, the case study site is visually nice.

The below site is the example of the case study site. (Figure 2)
