Geography Essay Example: Natural Hazards

Earthquake is a shaky movement of the earths crust, and these vibrations are produced by shifts that make up the earths surface. This action causes shakings to pass through and around the ground in the waveform. Consequently, the constructions or any erection that cannot stand the scale of the trembling gets damaged. Core source of the quake is volatile volcanic activities and tectonic activities. Rock falls, volcanic eruptions, explosions, and landslides can also cause an earthquake.

Tsunami is a sequence of giant waves that happen as an outcome of fierce underwater disturbance such as volcanic outburst, mudslide or earthquake. Moreover, about eighty percent of tsunami occur within the Pacific Ocean alongside the Ring of fire subduction areas, and the minor wave is typically not the sturdiest, continual waves get larger and stronger (OBrien, 2009). Also, a tsunami can travel at a haste of around 500 miles an hour and can maintain their energy meaning they can move through entire oceans with some degree of energy loss.

Tsunamis can be produced when the sea floor brusquely deforms and perpendicularly displaces the superimposing water. Tectonic tremors are a specific earthquake-related to the earths crustal deformation. In addition to the quake degree, universal climate change may also have a bearing on the happening of the tsunami.

Connections between earthquake and tsunami are that, when there is a quake near the coastline, there is a high option that damaging tsunami will follow (Bone, 2014). Equally, tsunami and earthquake are instigated by displacement of water or land, and they cause damage, vast in size and sturdy. It is noted that tsunami happens in the middle of any bodies of water and move a significant distance until it reaches the shoreline while quake occurs mostly in land.

How humans can deteriorate or alleviate the influences of natural hazards

Natural hazards are usually happening occurrences that have a disastrous influence on humanity. On the other hand, the hazard can be well-defined as an occasion that has the potential to cause damage. Persons have been impacting surroundings in a costly manner. Human actions such as degradation of forests, filling in wetlands, air pollution, engineering river and subverting climate are the multifaceted natural safety concerned and have made the influence of catastrophes more destructive (Handyman, 2016). Also, the huge growth of human inhabitants and the built setting contribute to the increase of calamities as folks look for access to water and land to produce food. These undertakings cause an alteration in universal weather conditions thus led to rising to various natural catastrophes for example wildfire and floods. However, the effect of calamity falls on deprived persons as they are living in susceptible areas and they have fewer incomes to prepare for or recuperate from the tragedy.

Calamity response has been attentive on improving weather forecasts before the proceedings and providing humanitarian assistance later which have saved many lives. Additionally, public tragedy readiness is vital in preventing and responding to the complete range of catastrophes that people now face. Debt aid for unindustrialized countries can free up resources for urgently needed calamity inhibition efforts as well as enhanced threat mapping can improve tragedy preparedness schemes, early warning, keeping human and financial loss as little as possible (Hallegatte, 2015). The regime should prioritize calamity risk reduction in all its strategies as well as land use that must pay attention to prevention, preparedness, susceptibility reduction and alleviation on what to do when a tragedy occurs. Also, the administration requires to back up this planning with real investments of resource to deliver these strategies.
