Earthquake

 How earthquakes affect humans, buildings, and bridges depends on many factors. The most important factors are earthquake magnitude, the distance from the earthquake centre (called the epicentre), and the geologic conditions at a site Primary effects of earthquakes are caused directly by the earthquake and can include violent ground shaking motion accompanied by surface rupture and permanent displacement. The most significant societal impact of the Kobe earthquake was the tremendous loss of human life.

Earthquakes have lots of energy that cause destruction on the planet. There are up to 3000 earthquakes per year and about 30 cause serious damage. Most of the damage occurs in LEDC’s because poor infrastructure and housing is not earthquake proof. The way forward is to manage earthquakes hazards in LEDC’s so when they do strike the area is not likely to suffer lots of damage and loss of life.

The occurrence of the earthquake hazard and the highest level of vulnerability is centred upon the economically developing nations. Discuss the truth of this statement and make recommendations concerning how LEDC’s might manage the earthquake hazards. Earthquake hazards are one of the three geological hazards that occur.

Earthquakes happen almost everyday, but they are just so micro that people do not even notice them. Researchers have documents saying, there was earthquakes up to the last 7 days. The Good Friday Earthquake of Friday, March 27, 1964 had a magnitude of 9.2, and was the most powerful recorded earthquake in U.S. and North American history, and the third most powerful ever measured by seismograph.

According to plate tectonics, the global distribution of epicentres is related to boundaries between lithospheric plates. Earthquakes at plate boundaries are called interplate earthquakes. Less commonly, earthquakes also take place in plate interiors and these are called intraplate earthquakes. The most active region in the world corresponds to the margins of the Pacific Ocean.

[36] Based on a study published in 2014, of the Main Frontal Thrust, on average a great earthquake occurs every 750 ± 140 and 870 ± 350 years in the east Nepal region. [37] A study from 2015 found a 700-year delay between earthquakes in the region. The study also suggests that because of tectonic stress buildup, the earthquake from 1934 in Nepal and the 2015 quake are connected, following a historic earthquake pattern.

Just because Turkey is considered an LEDC’s doesn’t mean that it has a more likely chance of an earthquake occurring. Japan is seen as a MEDC and is a hotspot for earthquakes as it is the meeting point for plates such as the Pacific from the East and the Eurasian from the west. Kobe has an earthquake in 1995 and caused mass destruction to the area.

Earthquakes are a very dangerous natural disaster, if strong enough; they could destroy the best-built buildings. They are caused by a sudden shift in the tectonic plates. Earthquakes can also cause other types of disasters too. They could cause tsunamis or volcanic eruptions. However earthquakes erupt unpredictable and can kill many people unpredictable.

For an example, there is an earthquake in Tohoku registered a moment magnitude of 9.0. The death toll from the earthquake is 13,000 and there is still more than 12,000 people missing. Second is the psychological effect to the survivors and this is also important as an effect of earthquakes. That is because earthquake may enable people to display mental disorders such as depression and neurosis.

The New Madrid Earthquake, the largest earthquake ever recorded in the next United States, occurred on February 7, 1812. It got its name from its main location in the New Madrid Seismic Zone, by New Madrid, Louisiana Territory. This earthquake was preceded by 3other major quakes: two on December 16, 1811, and one on January 23, 1812.
