Earthquake and tsunami research project for disaster prevention

Even the deep ocean is shallow in this sense because a tsunami wave is so long horizontally from crest to crest by comparison. Characteristics When the wave enters shallow water, it slows down and its amplitude height increases. Estimates suggest that more than 80, people lost their homes.

They have been documented in many places, including the Great Lakes, the Aegean Sea, the English Channel, and the Balearic Islands, where they are common enough to have a local name, rissaga. While Japan may have the longest recorded history of tsunamis, the sheer destruction caused by the Indian Ocean earthquake and tsunami event mark it as the most devastating of its kind in modern times, killing aroundpeople.

There are, however, a number of techniques that can minimize the harmful effects of tsunamis to the physical environment including built structures and to individuals and communities. Earthquakes and tsunamis are a serious threat in Peru "Peru is one of several South American countries facing frequent large earthquakes with magnitudes of 7 or greater.

Run up is measured in metres above a reference sea level. In addition,local peole can easily identify who are the natural leaders. In spite of their lower energies, on shorelines where they can be amplified by resonance, they are sometimes powerful enough to cause localised damage and potential for loss of life.

A tsunami can occur in any tidal state and even at low tide can still inundate coastal areas. A large-scale coupling simulation of an earthquake and tsunami is currently being performed by using K computer; see Fig. This research seeks to develop such an analysis method by using a high-fidelity model of more than 1, degrees of freedom, which K computer is able to compute.

These experiences have given the Peruvian people and their political representatives a strong concern for disasters, and a keen interest in technology that can mitigate the impact of such events, including enhanced anti-seismic technology and earthquake prediction. Only the largest waves crest. This method makes full use of E-Defense, the world-largest shaking table, for the validation of E-Simulator.

Victims and debris may be swept into the ocean. They dissipated before travelling transoceanic distances. The disaster survivors themselves are knowledgeable about local resources and can use their skills and knowledge so that costs are kept low.

Community-Based Approaches to Disaster Mitigation This paper discusses the importance of community as a part of disaster mitigation.

Projects undertaken involved raising homestead yards so that cattle, poultry, feed and other possesions would be place above flood level. Walls, hardened terraces, berms and parking structures can be built to block waves.

Research Fields include urban infrastructure systems and earthquake engineering. This map provides a fine or coarse-scale visualization for a small or large part of a target urban area, in a form of a static or dynamic image of the area.

The visualization of synthesized earthquake waves was studied by Prof. They are caused by earthquakes, landslides, volcanic explosions, glacier calvings, and bolides. Mitigation and prevention through: Peru is another country in a similar zone, and suffered a magnitude 7.

Shelters and community space were constructed as well as raised roads with culverts. This code was developed by using the Earthquake Simulator to provide a more accurate estimation of strong ground motions.

Case Studies

The Storegga Slide in the Norwegian Sea and some examples of tsunamis affecting the British Isles refer to landslide and meteotsunamis predominantly and less to earthquake-induced waves. Tuning is performed on the code so that it fits a newly developped architecture of K computer, which has a huge assembly of scalar CPUs.

The success of this method depends on correctly estimating the force of the tsunami.

The earthquake wave propagation of the off the Pacific coast of Tohoku earthquake was computed by using 24, nodes of K computer, with a highest computing speed of TFLOPS The advantage of the community-based approach is that projects can combine projects involving for example, housing and agriculture or health and agriculture.

In addition to individuals remaining alert to disaster prevention, experts need to work on analyzing subsurface structure and sea-floor topography, and researching technology for quake-resistant architecture.

Water can be steered to strategically placed angled walls, ditches and paved roads. In redevelopment of high risk areas four basic site planning techniques need to be considered.Project Strategic Programs for Innovative Research (SPIRE) "Field 3" Advanced Prediction Researches for Natural Disaster Prevention and Reduction ().

Provided by the Centers for Disease Control and Prevention (CDC). Surviving an earthquake and reducing its health impact requires preparation, planning, and practice.

cleanup, mold, environmental concerns, and coping with a disaster. Learn more. Be Ready! Earthquakes. This infographic includes important tips on being ready before and.

Tsunami Mitigation and Prevention. Tsunamis, like most natural disasters, are beyond human control. There are, however, a number of techniques that can minimize the harmful effects of tsunamis to the physical environment (including built structures) and to individuals and communities.

Goal: The MarDim Project aism to contribute to improve the early prediction ability of the earthquake and tsunami and to promote the improvement of awareness of disaster prevention.

It also aims.


That provides the foundation for a self-reliant entity for disaster prevention research in Peru that can address earthquake and tsunami issues. We will continue to ensure a proper follow-up after this project comes to an end. 3 Earthquake and Tsunami Research Project for Disaster Prevention, JAMSTEC, Showa-machiKanazawa-ku, YokohamaJapan.
