A sudden violent shaking of the ground, people run screaming, buildings begin to fall, the ground starts to crack. Then, as suddenly as it had started, it stops- this is the terrifying disaster life changing earthquake. Many terrible things can happen after earthquakes but there is help from other countries often after an earthquake. Some of the main and key things I will be talking about is the environment and who/what is affected. Also about who can help pluse what can happen during and after an earthquake.
During an earthquake
As tectonic plates grind together at a fault line, the rocks on either side stretch to absorb a certain amount of pressure. If the pressure becomes too great, the rocks shatter, releasing shock waves that shake the surface. During an earthquake there is lots of panic. People are running and screaming. Things start to fall and there is a lot of stress. The ground and other things are shaking. This is very scary for the people in the earthquake.
Aftershocks are earthquakes that follow after an earthquake except aftershocks are smaller. Aftershocks can continue over a period weeks, months or years. Main shocks are usually more powerful and longer lasting than aftershocks. They are normally in the same area as the main shock. An aftershock will not occur unless there was a main shock first. If an aftershock is larger than the main shock the aftershock is then the main shock and the original main shock is now a fore shock. After an earthquake things like landslides and tsunamis causing floods may occur. Fires can start by broken gas pipes and electric cables which can’t be extinguished if the water pipes are destroyed. Buildings can also start collapsing making things even more dangerous. Destruction of transport links such as roads and bridges can occur after an earthquake.
Who/what is effected by earthquakes
People are effected by things like getting injuries and even deaf. This can happen from things like collapsing buildings. After earthquakes diseases can spread making people sick. Sometimes houses can collapse leaving people’s properties broken and people homeless. Most of the time after an earthquake it can be hard to find food and some people start to die of hunger. Family can lose family members either if they have physically lost them and they don’t know where they are or they may have died. Animals can die just like humans in some of the same sorts of ways and what will happen if that animal is endangered or close to extension? Remember animal’s homes can be broken just like people and then they are left homeless. People may also have to be relocated to places like refugee camps because it is too dangerous and it’s not a good environment to grow up in. people that live in different country can even be effected because the government normally helps so then they have to raise taxes. Earthquakes can make people sad and miserable from some of the lives lost.
The effect on the environment
Sometimes earthquakes can create new habitats, ecosystems and attract new species. Usually earthquakes change habitats in subtle way. For example if it happens near a forest it may knock trees down. From some of these site changes it can stop population of animals. Scientific American uses the example of the 2011 earthquake in japan as an event that had a big environmental impact on people, animals and the surrounding ecosystem. After the 2011 japan earthquake it resulted in a lack of safe drinking water for humans and animals. Animals can die from lack of food, water and a good habitat. Seeds can be lost from plants and this means that we could lose that plant for good but luckily we have seed banks. There could be soil liquefaction which is when soil loses strength and stiffness causing it to behave like a liquid. Important natural landmarks can be lost. Nuclear reactor damage is a significant environment issue anytime a major earthquake occurs.
Who can help and how?
Health professionals (doctors, nurses, etc.) help by treating wounded and injured people. Emergency services like firefighters, police and paramedics help after an earthquake. Military help by rescue, delivery of supplies (water, food, shelter etc.) reconstruction. Dogs can help by looking around the area to find where people are dead/alive. Non – government – organisations (NGO e.g. Oxfam, would vison, care international etc.) help for aid/relief. People can donate money and also things like cloths, blankets, pillows, etc. after a bit builders come and help re-build. People could volunteer to go and help or donate to NGO’s.
This is important to know this because this can inform and encourage people to help out those how have suffered or been in an earthquake. In also explains how bad earthquakes really can be and I am shore that everyone will agree after reading this earthquakes truly are extremely bad. Everyone should know about earthquakes because of the dangers of them and they can be very scary. This piece has informed and explained about who can help after an earthquake, who is effected after an earthquake, how is the environment is effected and after and during an earthquake. Earthquakes are life changing disasters.
Systems + analysis
The trigger was the tectonic plates getting stuck then quickly releasing. If we changed the heat level and made it a little colder it may not move as much or at all. This may not make the tectonic plates move as much and that would make it be not as high of a magnitude. Or it may not even move at all but I guess it all depends on how cold or hot the earth’s core is. If it’s only a site change of heat there will probably still be an earthquake just not as big. We can’t really go into the earth’s core so we can’t really change the temperate. But global worming may make a difference.
information-report-assessment-carah – (this is my self assessment)
I believe that i have done a great job. I am really proud that i got 1000 words for my project. I know there is still a lot of areas to work on like my spelling and grammar. I think i need to work on getting more sequence and course + effect language into my writing but i sill think there is a lot of things to be proud of! Some of the things i think i did really well on is probably my length and my structure because i think i have done that really well.
