Concrete seawalls and coastal dykes were covered with concrete at the front, top and back. Tsunami waves smashed the coast, causing massive damage and flooding. NOAA Weather Radio … Home > Seattle Mama Doc. In this sense, the government policy of designing coastal protection is for the 150 year tsunami level, the so-called ‘Level 1’ or ‘Prevention Level’, ensuring that coastal protection will prevent tsunamis from penetrating inland to protect lives and properties (or economic activities). Japan is one of the best tsunami-prepared countries in the world, which is one of the reasons the world is still reeling from the 2011 event. The coastal plain along Sendai Bay experienced some of the farthest-reaching tsunami waters. Structural vulnerability to tsunamis is a critical issue in planning for tsunami-resilient communities. Scattering residential areas will isolate people and weaken community connections, and consequently, undermine the community's sustainability with shrinking population in rural areas. A new paradigm of coastal structural design has caused significant arguments in some Sanriku coastal communities. Prof. Katada's three principles: not to trust hazard maps (recognize the predictive limits), make the best efforts in any situation and take the initiative of evacuation in a community; these are highly recommended attitudes to overcome a disaster that exceeds all worst-case scenarios. A violent, magnitude 9-point-zero earthquake on March 11, 2011. Japan is one of the best tsunami-prepared countries in the world, which is one of the reasons the world is still reeling from the 2011 event. One can understand how, with this huge concrete breakwater, people in Kamaishi would feel well protected, and yet the 2011 tsunami caused 1253 fatalities in the city. A tsunami forecasting chart was drafted empirically. S.K. Donate Now. Third, the post-disaster paradigm shifts in reconstruction are discussed through a case study in Sendai city, Miyagi prefecture. A magnitude 9.0 earthquake struck off Japan’s northeastern coast, near the Tōhoku region. When the earthquake severed the connection between the nuclear power plant and the Japan electrical grid, the diesel backup system turned on as it was supposed to. For such cases, JMA has introduced methods to quickly highlight the possibility of underestimation in magnitude estimation and issues an initial tsunami warning based on the largest seismic fault expected in the area where the earthquake was triggered [21]. 2011 Japan earthquake and tsunami timeline March 11, 2011: Map of the 2011 Japan earthquake epicenter off the northeast coast of the Tōhoku region of Japan’s Honshu island. One reason for the striking difference in the number of fatalities was the level of preparedness. It is through such opportunities to know their risk that people learn that they must try to escape an at-risk area as soon as possible, when they feel strong ground motion or hear the tsunami warning or evacuation order issued. In Japan, sadly, evidence of the 2011 tsunami is easy to find. Governments can reduce risk, but communities must not become complacent. The map was delivered to every household before the 2011 event to announce the tsunami inundation zone in past events, list of evacuation facilities, and brief instructions for earthquake and tsunami preparedness. Conceptual image of tsunami-prevention facilities in Sendai city [49]. Tsunami safety has been a focus of coastal city planning throughout the nation. In the early morning on 3 March 1933, another major tsunami struck the Sanriku Coast. Then the question is ‘what are the great seawalls for?’. Japan Tsunami: Reminder For Parents To Prepare. Some areas are more protected than others, mostly in the northern coastal areas of the country. Based on the promptly estimated magnitude 7.9, 3 min after the quake (14.49 JST), JMA issued a Major tsunami warning to the coasts of Iwate, Miyagi and Fukushima prefectures with estimates of 3 m, 6 m and 3 m, respectively. Nevertheless, ports were pounded by the tsunami and the airport in Sendai was inundated. [Click here to read an independent report] 1. The tsunami caused 1280 dead or missing even in this well-prepared community. The so-called ‘Miracle of Kamaish’ is very good practice by school children who took the initiatives for a community's evacuation in Unosumai, Kamaishi city, Iwate prefecture. … News. It captured the moment of tsunami attack and contains important information of how the tsunami penetrated inland and local tsunami inundation flow characteristics. (b) The map of tsunami inundation extent in the 2011 event (www.gsi.go.jp). In many coastal communities, people have conducted regular evacuation drills and have held workshops to learn which areas are at risk, by referring to a hazard map prepared by the local government. The geological and historical evidence of irregularly recurring earthquakes in Japan is discussed elsewhere in this issue [2], while the Fukushima accident is discussed in [3]. An earthquake that struck Japan in March 2011 unleashed a massive tsunami. The discussion mainly focuses on structural measures such as seawalls and breakwaters and non-structural measures of … endstream endobj 98 0 obj <> endobj 99 0 obj <> endobj 100 0 obj <>stream This was critical, because those generators … Prepared for Members and Committees of Congress Japan’s 2011 Earthquake and Tsunami: Food and Agriculture Implications Renée Johnson Specialist in Agricultural Policy May 18, 2011 Congressional Research Service 7-5700 www.crs.gov R41766 . Tsunami warning information can inform people that they are in danger, but it cannot guarantee people's safety. Especially hard hit was the Okawa elementary school in Ishinomaki city, located 5 km inland along the Kitakami River: the school lost 74 pupils (70 killed and 4 still missing) out of a total of 108 and 10 teachers in the 2011 tsunami. A massive 9.0-magnitude earthquake struck Japan, Friday afternoon, on 11 March 2011 @ 0546 GMT 2. On Japan's east … Figure 1. Figure 2. Japan earthquake and tsunami, severe natural disaster that occurred in northeastern Japan on March 11, 2011, and killed at least 20,000 people. However, hard protection at the dyke toes was not mentioned. S.K. Especially in Iwate prefecture, 10 m high seawalls have been built along the coast to protect communities that have been devastated many times throughout history. Both events are probably similar with regard to the size of the earthquake and the height of the tsunami. VANCOUVER, British Columbia — In 2011, Japan was one of the most prepared countries in the world for a massive earthquake. The West Coast/Alaska Tsunami Warning Center and the Pacific Tsunami Warning Center issue watches and warnings to the media and to local, state, national, and international officials.   It was the fifth most powerful earthquake ever recorded, and within 30 minutes, a 133-foot high tsunami pummeled Japan's northeastern shoreline. Japan poorly prepared for tsunami nuclear plant threat, says IAEA. Many field surveys were conducted to identify the damage mechanisms of structures and their impact [27,34,35]. The discussion mainly focuses on structural measures such as seawalls and breakwaters and non-structural measures of hazard map and evacuation. (a) The measured heights of the 2011 Tohoku tsunami [22] and historical Sanriku earthquake tsunamis (1611, 1896 and 1933 events). It was widely believed that Japan was one of the most prepared countries in the world for tsunami events. “People [in the region] are fairly well-prepared. A watchissued along with a tsunami warningpredicts additional tsunami arrival times for a geographic area defined by the distance the tsunami could travel in more than a few hours. %%EOF In fact, its tsunami forecasting technologies and numerical models were exported to many foreign countries that needed support, such as Indonesia, Thailand, Mexico and Peru. For that reason, Japan had already introduced a number of defences prior to 2011. The seawall was designed for Level 1 tsunami (the height equivalent to the historical tsunami heights in the past 150 years and storm surge heights in the past 50 years). The Sanriku Coast lies on the north-eastern side of the island of Honshu (in the Tohoku region), corresponding to Aomori, Iwate and Miyagi prefectures. contributes on conception, structure and drafting of the article. Onagawa town, Miyagi prefecture (10 014 population before the earthquake), is one of the towns devastated by the 2011 Tohoku earthquake tsunami. Black dots on the coastline indicate the points of the 2011 tsunami height measurement. Japan earthquake, tsunami and Fukushima nuclear disaster: 2011 review. How can we educate children to be prepared? Its construction started in 1978 and was completed in 2009, requiring an investment of almost 30 years and 120 billion yen. These hydrodynamic parameters appear capable of devastation for the coastal forests that have been planted for the past centuries. Ministry of Land, Infrastructure, Transport and Tourism. endstream endobj startxref also contributes on drafting the article specifically in sections of ‘Pre-2011 Paradigm’ and ‘Response to the 2011 Event’. This 18 m tall lighthouse built on a cliff 10 m a.s.l. A tsunami is caused by an earthquake that occurs under the sea and plate cause the sea to jump up causing a massive wave. Consequently, teachers decided to head for the bridge, walking along the river. Tōhokun maanjäristys (jap. The tsunami generated by the earthquake attacked the Japanese coast the next morning. The tsunami attacked the town at 15.20 JST (34 min after the earthquake occurred) and caused 816 fatalities and 125 missing. However, the affected area of this event was much more extensive than in those historical events. Before the 2011 event, the general belief of a safe place to survive a tsunami attack was robust RC buildings. In this sense, the 11 March 2011 event was the largest known tsunami event in Japan. Note that this fragility curve was obtained using the form of probability of structural destruction as a function of measured tsunami flow depth. Also, the central government decided a policy of coastal protection such as seawalls and breakwaters [45], which would be designed to ensure their performance to a potential tsunami level of up to the approximately 150 year recurrence interval. In the 2011 Tohoku event, at least eight RC or steel construction buildings were found overturned or washed away in Onagawa town and Miyako city. In … (a) The measured heights of the 2011 Tohoku tsunami [22] and historical Sanriku earthquake tsunamis (1611, 1896 and 1933 events). The map was delivered to every household before the 2011 event to announce the tsunami inundation zone in past events, list of evacuation facilities, and brief instructions for earthquake and tsunami preparedness. 2. In a subduction zone, one plate slides beneath another into the mantle, the hotter layer beneath the crust. The responses to the 2011 event are discussed specifically … For the largest-possible tsunami level of the more than 150 year recurrence interval, the so-called extreme event (such as the 2011 Tohoku event), the government refers to this as ‘Level 2’ or ‘Preparedness/Mitigation Level’ to protect human lives and to reduce the losses and damage with comprehensive disaster management measures including coastal protection, urban planning, evacuation and public education. 3. It lasted 6 minutes. The act is based on the following new principles: (i) properly combine structural and non-structural measures to minimize damage; (ii) with sufficient consideration to socioeconomic conditions, coastal protection facilities should be aimed at protecting people's lives, property, industrial and economic activities, and national land against a certain scale of relatively frequent tsunamis; (iii) tsunami disaster mitigation strategies should be based on multiple protection that combines structural and non-structural measures, with consideration of regional characteristics. The inundation model results are validated through the comparison with field data in terms of local inundation depths, inundation heights [22,23]. Japan should use what it already knows and learn from its experiences in order to prepare more effectively in case of a future natural disaster. was hit by an approximately 30 m tsunami. The nonlinear shallow water equations are discretized by the staggered leap-frog finite difference scheme with bottom friction in the form of Manning's formula according to the land-use condition [37]. These principles are now highly valued as one of best practice/outcome of disaster education. “If this could happen to Japan, what about us?” [26] analysed survivor videos and measured flow velocities of about 10 m s−1 for the inundation flow that penetrated through the city [26], and produced a hydrograph of the tsunami. (Online version in colour. Japan faces up to failure of its earthquake preparations. n0 Nevertheless, the tsunami disaster countermeasures were insufficient against the 2011 event. We revisited the lessons of the 2011 Great East Japan Earthquake Tsunami disaster specifically on the response and impact, and discussed the paradigm shift of Japan's tsunami disaster management policies and the perspectives for reconstruction. The Fukushima Daiichi Nuclear Power Plant cooling … by . Coastal infrastructure such as breakwaters and seawalls cannot always protect life and property: even great seawalls can fail. The response capabilities the children learned at school helped them to overcome a disaster that exceeded all worst-case scenarios. Based on this new reconstruction plan in the tsunami-affected area, Sendai city has formulated its tsunami evacuation plan [50] to protect lives. We are grateful to Professor Costas Synolakis for valuable comments. Many pupils and teachers were affected by the 2011 Tohoku earthquake and tsunami. After the Meteorological Business Act was enacted in 1952 [5], the forecasting system covered the whole coast of Japan. These features implied that the 2011 earthquake was probably a combination of the 1896 Sanriku ‘tsunami earthquake’ and a Jogan-type deeper interplate earthquake [14]. 5. Figure 5. However, when implementing, this design paradigm has triggered conflict and debate.

The tsunami source scenarios considered in preparing hazard maps are determined by the results of long-term evaluation of seismic activities. This contribution revisits the lessons of the 2011 Great East Japan Earthquake and Tsunami disaster specifically focusing on the response, impact and paradigm shift of Japan's disaster management policies and discusses perspectives for enhancing national resilience. The tsunami was predicted to hit Tuvalu at 1.30am.

To evaluate how these protection measures will work in terms of tsunami disaster reduction, we conducted tsunami numerical modelling with the 2011 tsunami source scenarios, namely ‘Level 2 tsunami’ scenarios of the largest-possible tsunamis, and the present reconstruction plan. He told the students not to trust hazard maps, to make their best efforts in any situation, and to take the initiative of evacuation in the community. Japan is one of the most well-prepared countries in the world to deal with the threat of a tsunami.Warning systems are in place, and concrete sea walls wrap around much of the coastline. Revisiting the modern histories of Tohoku tsunami disasters and pre-2011 tsunami countermeasures, we clarified how Japan's coastal communities have prepared for tsunamis. As observed in the tsunami fragility curves, structures were especially vulnerable when the local flow depth exceeded 2 m, while a 6 m flow depth would cause everything to be washed away. In the past, nothing has been reported about the devastation of RC structures except for the case of the Scotch Cap lighthouse in Unimak island that was destroyed by the 1946 Aleutian tsunami [40]. National Institute for Land and Infrastructure Management. Thanks to the recent advances of hand-held video cameras and mobile phones, however, many tsunami survivors have attempted to capture the moment of tsunami attack on their communities and have uploaded videos to the Internet (we should note that taking photos or videos of a tsunami should only ever be done from a position uphill, never from a beach). At the same time, rapid economic growth resulted from the ‘Income-Doubling Plan’ that started in 1960, an age of rapid growth, could cover the expensive construction costs. Their very quick and resolute response prompted local residents and even the students and teachers in a neighbouring elementary school to follow and consequently saved lots of lives. East of Japan, the Pacific plate dives beneath the overriding Eurasian plate. Shortly thereafter, the tsunami penetrated along the river and overtopped the riverbank, sweeping away pupils and teachers. What was not adequately prepared for was a tsunami of such scale. Figure 5b shows one example from preliminary results. It was centered about 80 miles offshore, and tsunami warnings went up immediately. In one sense, the belief was right. N.S. Tsunami warning information can inform people that they are in danger, but it cannot guarantee people's safety. Hazard maps have two functional aspects.

Revisiting the modern histories of Tohoku tsunami disasters and pre-2011 tsunami countermeasures, we clarified how Japan's coastal communities have prepared for tsunamis. The 2011 earthquake off the Pacific coast of Tōhoku (Japanese: 東北地方太平洋沖地震, Hepburn: Tōhoku-chihō Taiheiyō Oki Jishin) was a magnitude 9.0–9.1 (M w) undersea megathrust earthquake off the coast of Japan that occurred at 14:46 JST (05:46 UTC) on Friday 11 March 2011, with the epicenter approximately 70 kilometers (43 mi) east of the Oshika Peninsula of Tōhoku and the hypocenter at an … [41]. In the 2011 tsunami/earthquake, some damage could have been avoided if Japan were as prepared for the tsunami as they were for the earthquake. What is the requirement that should be put into place for safer school buildings that can withstand both strong ground shaking and a devastating tsunami? Consequently, the devastated trees headed inland producing large amounts of waste, and may have caused more destruction. It shuts down transport systems and nuclear power stations to … The key role of academia, from the engineering point of view, is to verify and evaluate if these plans will really work for future disaster reduction. The tsunami run-up height reached up to 40 m in Iwate prefecture. A remarkable paradigm shift in coastal protection policies is on seawall design. Japan earthquake: country better prepared than anyone for quakes and tsunamis No country on Earth is better prepared than Japan to deal with earthquakes – or the tsunamis that result from them On March 11, 2011, a 9.1 magnitude earthquake occurred 231 miles northeast of Tokyo. Opinion. This resulted in the death toll of 22 000. (b) The map of tsunami inundation extent in the 2011 event (www.gsi.go.jp). The 6.3 m s−1 of inundation flow of the ascending tsunami caused a drag force per unit meter width of 100 kN m−1 [32]. After the 2011 Tohoku tsunami attack, the international post-tsunami survey team was established and conducted a nation-wide survey [22,23] to record the tsunami run-up heights, flow depths, inundation extent and the impacts. The contents of the warning were classified into three categories, according to the estimation of tsunami height: ‘Major tsunami’ (estimated more than 3 m), ‘Tsunami’ (estimated 1 or 2 m) and ‘Advisory’ (0.5 m or less). Even now, numerical simulations cannot predict everything that will happen in a disaster. Figure 3. Die höchste maximale Auflaufhöhe erreichte der Tōhoku-Tsunami 2011 mit 40,1 m in der Ryōri-Bucht/Ōfunato und war damit der höchste je in Japan gemessene Tsunami. Applying a video analysis technique, the tsunami flow velocity can be determined to understand the characteristics of tsunami inland penetration and impact on structures [25–30]. Re-cap of last week Japan was hit by a massive 9.0 magnitude earthquake that caused a tsunami. Black dots on the coastline indicate the points of the 2011 tsunami height measurement. Amalgamation Techniques Pre-March 1 lath Japan has certainly always been the most prepared country with regards to earthquakes, especially vials-a-vials Its past quake events . The 2011 Great East Japan Earthquake and Tsunami disaster left many lessons to be learned regarding Japan's disaster management policies. That Japan was not adequately prepared for the tsunami that hit the northeastern Honshu coast on March 11, 2011, first became apparent at the Fukushima Daiichi nuclear power plant. Even in Onagawa town, 28 people were saved inside the boiler room of a five-storey RC building which was totally submerged by the tsunami inundation flow. Throughout the case study in Sendai city, the proposed reconstruction plan was evaluated from the tsunami engineering point of view to discuss how the post 2011 paradigm was implemented in coastal communities for future disaster mitigation. (The Okawa elementary school building withstood the devastating tsunami inundation flow, but was totally submerged.) Only 62,000 sought shelter, says Kawata. Using this result, Sendai city determined the land-used plan and the area of housing reconstruction and relocation. This earthquake generated a tsunami that struck Japan as well as various locations around the Pacific Ocean. Consequently, all the instrumentation and control systems at reactors 1–4 were lost, and a series of explosions occurred, causing extensive radioactive contamination. After this tsunami, several villages were relocated to high ground at the personal expenses of individuals or village leaders [5]. (a) Tsunami hazard map published for Kesennuma city, Miyagi prefecture. h�bbd``b`��@�q/�`-�����_@b�A�7!$8> �6 �H�?RW�@����? Field measurements of extreme inundation are now used for validating numerical models [8,9]. In addition to the 1896 Meiji and the 1933 Sanriku tsunamis which killed 22 000 and 3000 people, respectively, the experiences of the 1959 Ise-wan super typhoon (Vera) and the 1960 Chilean earthquake tsunami strongly motivated Japan to develop coastal protection infrastructures of seawalls and breakwaters. The highest tsunami run-up height was 38 m at Ryori Shirahama in Iwate prefecture. De zeebeving nabij Sendai in 2011 was een zware zeebeving die zich voordeed op 11 maart 2011 voor de noordoostkust van het Japanse eiland Honshu.Het epicentrum van de beving, die een kracht van 9,0 - 9,1 op de momentmagnitudeschaal had, bevond zich voor de kust van de prefectuur Miyagi op circa 370 km ten noordoosten van de Japanse hoofdstad Tokio en circa 130 km ten oosten … Throughout Japan’s long struggle with seismic activity, tsunamis have devastated the … When the 2011 event occurred at 14.46 JST on 11 March, JMA's initial estimate of the magnitude (Mjma) was 7.9, which is a combination of the magnitude based on ground displacement for relatively large earthquakes and the magnitude based on ground velocity for relatively small earthquakes [20]. The earthquake and subsequent tsunami that struck northeastern Japan on March 11 was perhaps the most widely recorded natural disaster in human history. (b) The extent of the tsunami inundation zone with the measurement of the run-up heights at tsunami inundation limit in Sendai Coast [23].Download figureOpen in new tabDownload powerPoint. Japan's historic earthquake and tsunami serve as a great reminder to prepare our families for catastrophic events. Seawalls should be designed with the assumption of overtopping and destruction, and communities should not rely on coastal infrastructures alone for protection. Here is a list of U.S. Navy vessels being positioned for earthquake and tsunami relief, according to the Pentagon. The great plates are rough and stick together, building up energy that is released as earthquakes. The seawall was designed for Level 1 tsunami (the height equivalent to the historical tsunami heights in the past 150 years and storm surge heights in the past 50 years). For the largest possible tsunami (Level 2), the city secures multiple facilities of coastal forest, artificial hill, raised road and evacuation sites to protect citizens' lives. It was originally reported at a magnitude of 7.9, but later was upgraded to 8.9 and then to a 9.0. How should teachers be trained to provide appropriate guidance to save children's lives and their own? In addition, a significant feature of the 2011 tsunami was the wide extent of the inundation zone; for example, on the Sendai plain (figure 2b), the tsunami inundated more than 5 km inland, causing devastating damage to populated areas and rice fields. , some reinforced concrete buildings were totally destroyed, and communities should rely!
