Crisis Management of Tohoku; Japan Earthquake and Tsunami, 11 March 2011
Like the underwater earthquake, this too unleashed a massive tsunami. Within a week of the incident, the death toll had risen to 4,, with 7, reported missing and 2, injured [source: CNN ].
Tragedy swelled into crisis, however, as the tsunami also destroyed the generators required to circulate water through the nuclear reactor at the Fukushima-Daiichi facility. The reactor shut down with 10 minutes of increased seismic activity, but it still required an operable cooling system to prevent dangerous increases in core temperature from decay heat in the radioactive core.
Water temperature and pressure continued to rise and radiation began to split the water into hydrogen and oxygen. Hydrogen explosions breached the reactor building's steel containment panels.
Essay Japan's Earthquake and Tsunami: Operation Tomodachi
Japanese authorities were now faced with the challenge of cooling the Fukushima-Daiichi and stopping the leak of deadly radiation from the crippled facility. The ravages of a powerful tsunami can be truly catastrophic. On the next page, we'll learn what can be done to predict their formation. How to Prepare for a Flood.

Prev NEXT. An aerial view of tsunami and earthquake damage off the coast of Northern Japan as seen from a U.
Additionally, new apartment blocks are constructed to accommodate vertical evacuation. In the workshop, the students went through a five-step process, that took them from a single-disciplinary analysis with a proposed scope of solutions in the first step, to knowledge integration with two, three, four and finally five diciplines the so-called charrette approach.
In the two remaining multidisciplinary groups, the participants brought their analysis of Yuriage to a shared, interdisciplinary, understanding of how alternative interventions, proposed by a certain discipline, affects other possible interventions. At the end of the multiple-day workshop, a vision and preliminary design proposal, and an integrated design and engineering strategy for the redeployment of essential services and infrastructures in Yuriage was presented.
The methodology, which required participants to offer a set of interventions on a scale from extreme engineering proposals and nature-based alternatives, permitted different levels of interactions between the disciplines. Thus, alternatives were weighed, and balanced, in an integral strategy for urban and landscape re development.
Preliminary insights based on the workshop are that the Japanese approach to reconstruction in post-disaster area may be one of the advanced globally.
It relies heavily on large infrastructures sea walls , spatial planning measures strict zoning of vulnerable land uses in tsunami-1 and tsunami-2 areas , building codes especially to create earthquake-resistant buildings and evacuation-strategies horizontal and vertical. On the other hand, based on the example of Yuriage, Japan struggles with the question of how to re build attractive settlements for an aging and shrinking population. Beside the fantastic experience on the case study, the real experience was the journey itself.
