Technology Is the Best Way to Reduce the Impact of an Earthquake - to What Extent Do You Agree with This View

The key lessons that have been learnt from the event is that those in charge of ensuring the safety of Haiti’s citizens need to recognize the risk of their location and acknowledge the advice of seismologists for any future seismic events. The implementation of early warning systems and the use of SMS messaging as seen in Japan would greatly reduce the hazard of an earthquake. In addition, environmental management is crucial for the long term survival of Haiti, strategies to reduce deforestation and claiming back land unsuitable for housing would lead to better soil quality and less risk of landslides and liquefaction to buildings should another event occur. However, the main lesson to be drawn from the disaster is the need for proper construction techniques and guidelines. Education and training to provide construction workers with enough knowledge to make future infrastructure earthquake

The San Andreas fault line has caused constant development nightmares for large urban areas such as San Francisco as well as the other cities built on top of it. Fault lines are one of the side effects of the earth’s tectonic plates shifting that can result in devastating earthquakes. Some of the most devastating earthquakes in our modern era have occurred along the San Andreas fault line due to a dense population. The most notable and destructive earthquake on the San Andreas fault line occurred in San Francisco in 1906. The reason this earthquake was so deadly was because of its magnitude and the city’s poor planning. This earthquake was a wakeup call for San Francisco and force the city to revolutionize its knowledge on earthquakes and how to protect their city. Today San Francisco is one of the most well prepared cities for an earthquake and has made great discoveries in earthquake safety measures. The 1906 earthquake in San Francisco has drastically changed how the city has developed its zoning and building code policies, and its earthquake research.

Despite decades of research and the use of modern technology, scientists are still not able to detect in time an imminent earthquake. Even though seismologists mostly know where the faults are and are able to closely monitor the rate of activity on them ranging from a scale of a year to a decade and even a century, a solid short-term day to month forecasting in order to identify the places at risk, still is an insoluble problem. Although this may be true, some scientists in diverse fields choose to follow a different and a rather controversial approach on the subject by studying the unusual animal

Earthquakes have afflicted the world since its inception. The sudden release of energy from volcanoes or displacing of earth plates can result in disasters of extreme magnitude. These usually naturally occurring phenomenon have been responsible from wiping out entire towns throughout history and until today continue to produce major loss of life and infrastructure. It can take years for a city or country to recover from a major event of this kind and when a third world country is involved, the result is usually exponentially worse than in a developed country. In the past decades Japan, Chile and Haiti have suffered the devastation an earthquake produces. This document will concentrate in Haiti, a small country in the Caribbean. On

Over more than 50 decades there has been multiple earthquakes that have been caused by the activity that takes place beneath and above the surface of the earth. For every earthquake there are various effects and consequences, these are generally not preventable but teachable moments. As we study and explore landforms we learn and better understand how today 's structures came about, what took place decades ago and where do we go from here. Thanks to the technology and inquiring minds we are able to study past events like the 1906 San Francisco earthquake and the 1964 Alaska earthquake. In comparing these two events we can get an overview of what happened and better prepare ourselves for something like that in the future.

Before an earthquake even occurs it is possible to predict roughly where and when it will happen due to detailed seismic records and sophisticated technology such as radon gas emissions, remote sensing and low-frequency electromagnetic activity. In MEDCs like the US, especially around California, dedicated groups of scientists devote their careers to the investigation of earthquake hazards and management. They have access to the latest technology, computers and forecasting to enable them to find out and report back to the wider population about any possible risks. However, in LEDCs like Iran, researching and educating their population about earthquakes is not a priority. Their main goal is to develop their profitable oil reserves and they are still relatively underdeveloped in comparison to the US with a GDP per capita of $818.7 billion compared with America’s $14.66 trillion. The fact that they are not fully developed as a nation puts them at an immediate disadvantage in terms of their ability to prepare for an earthquake.

The volcanic eruption of Nevada del Ruiz in Bolivia is another example of how some of the poorest people can be so badly affected by these events. The US volcanologist office warned the local authorities about the impending eruption but the authorities did not understand the seriousness of the situation and so did not warn any of the people. 28000 people died from the eruption and the secondary effects of the mudslides and lahars that formed. This lack of education of the risks of the seismic and volcanic hazards in the poorer countries often makes them much more vulnerable.

The following paper is on the economic effects of the Cascadia subduction fault line earthquake. This earthquake is predicted to happen within the next fifty years, and it's predicted to devastate everything west of Interstate 5. The earthquake can range from a 8.0 magnitude to a 9.2 magnitude, and will impact "some hundred and forty thousand square miles... and some seven million people" (Schulz).

Earthquake early warning systems alert devices and people when shaking waves generated by an earthquake are expected to arrive at their location. The seconds to minutes of advance warning allow people and systems to take actions to protect life and property from disastrous shaking. Devices such as isolation systems and dampers are designed to reduce vibrations of structures being effected in an earthquake and are added to the design of some modern buildings mainly in Japan. Advanced radar and infrared cameras take a series of images collecting data to identify signs of earthquakes. Advanced Interferometric Synthetic Aperture Radar shows fault movements over a period of years. Modems and Data Processing centres receive data collected by satellites to analyse the trends recognised in the electromagnetic emissions, radar pictures, infrared readings and elf

Natural disasters are a huge challenge for the planet because of the adverse effects that are associated with them. One of the major earthquakes to have shaken the earth is the Great Sendai Earthquake or Great Tōhoku Earthquake that occurred in 2011. The event started when a powerful earthquake hit the northeastern Japan on March 11, 2011, and resulted in a widespread damage on land. A series of massive tsunamis later devastated many parts of the coastal regions of the country with the worst affected being the Tohoku region. The tsunami further resulted in a major nuclear accident that damaged distant regions on a power station located along the coast. The economic effects of the tsunami qualify it as one of the major natural disasters because it affected Japan’s economic stability as the country ended up resorting to importing as an alternative to cover the loss.

Predicting earthquakes can help prevent death and injury rate by sending out warnings. This will help people evacuate buildings, schools, or the whole area. Some sources claim that predicting earthquakes

Scientists can’t predict earthquakes but may be able to give a 20 to 30 second warning to provide 30 seconds of evacuation. Scientist can get an idea of when an earthquake might happen by putting GPS trackers on fault lines. Seismographs can measure earthquakes. They are able to pick up the different types of waves that create and earthquake. These different waves can help scientist find out where the epicentre of the earthquake is.

Earthquake Hazards occur when there are adverse effects on human activities. This can include surface faulting, ground shaking and liquefaction. In this essay I will be discussing the factors that affect earthquakes, whether human such as population density, urbanisation and earthquake mitigation or physical such as liquefaction, magnitude, landslides and proximity to the focus.

Purpose: Everyone will think that we are living in a peaceful state now and ignore to pay attention to the natural disaster information. On the contrary, this thought in your mind will reduce your sense of crisis. Believe or not, increase a sense of crisis of the earthquake and learn more earthquake information can decrease the damage when the earthquakes occur in our life

In the U.S. alone, the average annual cost to repair damage caused by earthquakes is $4.4 billion USD. The worldwide figure is much larger than this but unquantifiable due to poorer countries unable to accurately determine the amount of damage that occurred. Year after year the cost of damages barely fluctuates from these ridiculously high figures and money must be pumped into repairing the damage done. Although a lot is being learnt about earthquakes and the fact that humans are now normally able to be alerted in time to evacuate the area the earthquake will affect, there have been no breakthroughs into reducing the amount of damage earthquakes cause to buildings and infrastructures.
