An analysis of the natural disasters and the issues of the tsunami

Consequently, the tsunami stranded cargo ships and barges and destroyed a cement factory near the Lampuuk coast. We know that natural disasters happen. In unusual neurological disorders began to strike people living in fishing villages along Minamata Bay, Japan.

They grow in height when they reach shallower water, in a wave shoaling process described below. Thousands of lives were lost and entire towns were devastated. At the same time, technological innovations provide unprecedented opportunities to build resilience and deepen connectivity.

Their existence was confirmed inwhen a giant landslide in Lituya Bay, Alaska, caused the highest wave ever recorded, which had a height of meters over feet. The Japanese Headquarters for Earthquake Research Promotion This megathrust earthquake was a recurrence of the mechanism of the earlier Sanriku earthquakewhich has been estimated as having a magnitude of at least 8.

The area where the earthquake occurred is where the Pacific Ocean floor is subducting or being pushed downwards under Alaska. Their seismic moments can account for a significant fraction of the global seismic moment across century-scale time periods.

This earthquake was particularly unusual in the sense that it did not occur on the inter-plate thrust fault within the subducting Pacific plate but further out on the outer-rise region. Inten-year-old Tilly Smith of Surrey, England, was on Maikhao beach in Phuket, Thailand with her parents and sister, and having learned about tsunamis recently in school, told her family that a tsunami might be imminent.

If the first part to arrive at shore is the ridge, a massive breaking wave or sudden flooding will be the first effect noticed on land. Poverty and the crippling effects of third world debt are certainly issues that need more coverage by the mainstream.

After that, rebuilding lives and the resources on which those lives depended is key. The survey indicates that km section along the boundary of the plates shifted motion that triggered the sudden displacement, causing the huge tsunamis. Communities have fewer fatalities and property damage if they plan before a tsunami arrives.

A subsequent analysis will provide estimates of energy that went into tsunam generation and will attempt to reconcile results obtained by numerical modeling with the recording of the tsunami at DART buoy The break caused the sea floor to rise by several metres. Natural Hazards can also be divided into rapid onset hazards, such as Volcanic Eruptions, Earthquakes, Flash floods, Landslides, Severe Thunderstorms, Lightening, and wildfires, which develop with little warning and strike rapidly.

The seismic waves of the earthquake were felt across the planet; as far away as the U. There were reports from Apia that the shaking lasted for at least two minutes.

The intraoceanic convergence tectonics along the Tonga Trench and the adjacent forearc between 14 S and 27 S Latitude are somewhat complicated and vary from North to South. Because the plate boundary and subduction zone in the area of the Honshu rupture is not very straight, it is unusual for the magnitude of its earthquake to exceed 8.

The strongest known deep aftershock sequence.

Seismological evidence for tearing of the Pacific plate at the northern termination of the Tonga subduction zone, Geology; July ; v. This energy is equivalent to over 1, times that of the Hiroshima atomic bombbut less than that of Tsar Bombathe largest nuclear weapon ever detonated; however, the total physical work done MW and thus energy by the quake was 4.

We conclude that ‘natural disasters’ provide both opportunities and risks for raising awareness of environmental issues, mobilising funding and directing action to environmentally and socially vulnerable areas of the world.

Natural Disasters Natural disasters affect many people in the world. Over 31, number of people have died from natural disasters since A natural disaster is the effect of a natural hazard including tornadoes, tsunamis, and earthquakes and more. Chapter 39 - Disasters, Natural and Technological DISASTERS AND MAJOR ACCIDENTS.

Pier Alberto Bertazzi. Type and Frequency of Disasters. Inthe 44th General Assembly of the United Nations launched the decade for the reduction of frequency and impact of natural disasters (Lancet ).

The Indian Ocean earthquake occurred at UTC on 26 December, with an epicentre off the west coast of northern Sumatra and a magnitude of – M w, reaching a Mercalli intensity up to IX in certain areas. It was an undersea megathrust earthquake caused by a rupture along the fault between the Burma Plate and the Indian Plate.
