Topic > On the sharp edge of the fall

Among many natural disasters, earthquake is considered one of the most dangerous and evil. Until these days, predicting shocks was one of the most difficult tasks for scientists to do. When earthquake occurs, giant cracks occur in the Earth's stone shell called the lithosphere. The ascending edges of the ripple emit elastic waves that propagate at a speed of several kilometers per second and quickly reach the Earth's surface causing catastrophic consequences. According to geological and seismological data, this is the result of a sudden discharge due to dynamic stress caused by processes occurring in the bowels of the Earth. In some cases, the length of these cracks emerging from the depths of the planet to the surface reaches hundreds of kilometers, and the vertical and horizontal displacements of the crack edges are about several meters. An earthquake is a tremendously dangerous natural disaster because seismic strikes occur exceptionally quickly causing serious consequences within seconds, destroying cities and causing the death of hundreds and thousands of inhabitants of our planet.

Something forces me to wake up, unnaturally opens my eyelids and pushes me out of bed pulling in the opposite direction; and the earth's gravitation is believed to have changed from the original 9.8 to about 25.7. Rolling over, I try to close my eyes and fall asleep but suddenly my bed begins to tilt to the side and my silky sheets and comforter slide towards the floor. In complete confusion, I sit on the bed holding the edge of the chair and trying to focus my vision. My sight immediately falls on the wall in front of my bed covered in frames, posters of my favorite cartoons and prizes. As I get closer, I notice that some frames are broken, paintings are hanging out of them, and pieces of glass are scattered all over my carpet. To get a clearer understanding of what is happening right now, I look around the room and notice that my ceiling lamp is starting to swing at a very slow speed from left to right. I turn away from the lamp for safety and see my books sliding down the shelf tearing the pages as they collapse together falling to the floor and hitting the hard cover on the dark wood parquet. I quickly rush to pick them up and, without realizing it, I accidentally step on a piece of glass protruding from the carpet with its sharp edge; small drops of blood begin to drip onto my white carpet. Slowly crawling to the side and trying to shield myself from everything around me, I do my best to reach into the box of tissues to wipe the blood from my foot. However, as I stand up, my legs begin to shake and the feeling of unsteadiness comes over me. I look around the room and it seems to me that I am locked in some kind of box and that someone keeps shaking it and spinning it from different heights. Fear crosses my mind and I start to panic, which causes my heart rate to increase. , and my blood pressure was pounding in my head like an echo, giving me a terrible headache. I try to call my parents, but due to shock and fear no noise comes out of my mouth, I feel paralyzed and uncontrollable. Luckily my father rushes into the room to catch me as I begin to faint, screaming, “Earthquake! It's an earthquake! We have to go down the stairs!” I can't walkentirely because there is a small piece of glass that is stuck inside my foot causing me a lot of pain every time I apply pressure; my father picks me up and carries me into the living room. My father orders me to protect my head by placing my hands on it and orders me to sit under the table until he comes back. For the next five minutes I sit alone under the table and look out every second trying to see my parents packing in the front room. Carrying a large bag with all the essential documents, my parents rush into the living room, rushing to reassure me that I'm okay and catch up with me. We hear a loud and violent noise, but at first we were not aware of what it was. Then, as we lean over the table, we notice the wall above us begin to crack, making it look like it's about to collapse on us like a sandcastle. The crack moves along the wall from the top of the ceiling to the bottom in almost 10 seconds. Thinking that my life will end in a matter of seconds, I close my eyes and hold my breath as I hug my knees to my chest. The next ten minutes pass very slowly as we keep ourselves in the same positions hoping that everything will finally end, having no idea of ​​the upcoming future results. My father asks to hold hands and then says with a slight smile: “The earthquake is over, trust me! We can go out now. ”After his words, the sweat of nervousness flows through my body, and I almost start to faint as the very salty tear drips down my face. All senses are slightly starting to come back to me, forcing the fear to leave as I realize that my family and I are finally safe and well. During my first earthquake experience, my family and I lived in Almaty, Kazakhstan, a country between China and Russia, known for the beautiful Zailiyskiy Alatau mountains. Earthquakes have always been a problem for the city of Almaty as magnitudes can reach up to 7-8. Overall, many regions of the Earth are more seismic than others, causing fewer or perhaps more earthquakes in people living in those regions. Please note: this is just an example.

For example, countries such as Türkiye, Japan, Nepal, Ecuador and Indonesia are considered countries with strong seismic activities. Our earth is divided into four main layers: the inner core, the outer core, the mantle and the crust where the tectonic plates are located. The place where tectonic plates meet is called a boundary, and several different types have been recorded over the years. The first type is convergent boundaries that occur when two plates begin to move towards each other. The second type is called a transform boundary during which the two plates move in opposite directions from each other. The third type, when plates move away from each other, is called divergent boundaries that cause earthquakes. Because the edges of the plates are rough, they remain stuck while the rest of the tectonic plates continue to move; when the plate moves far enough, the edges suddenly break away on one of the faults causing an earthquake. During an earthquake, energy escapes from the faults in different directions in the form of seismic waves at a very rapid rate. Then the seismic waves begin to shake the earth as they move the thought, however, when they finally reach the surface of the earth they begin to shake the ground and anything else that is on it causing damage to all properties and human lives. Scientists always have.
