The worst earthquake in history in Turkey and Syria

In the past few days, the worst earthquake of this century, with a magnitude of 7.8 on the Richter scale, has wreaked havoc in the south and north-western border areas of Syria (Turkey). Thousands of people were killed and millions were injured. The epicenter of the earthquake is 23 km away from southern Turkey and the depth is 17.9 km.

Experts say that this is the biggest natural disaster that Turkey has faced since 1939, many areas have been wiped out. The earthquake fault line in the affected areas is relatively quiet, due to which the structures of the buildings are not given much attention. Most of the buildings are weak. This is also one of the reasons for the great destruction caused by the earthquake.

Earthquakes are natural disasters that cannot be predicted. Therefore, there is no way to prevent them. That a 7.5 magnitude earthquake will occur sooner or later in this area has surprisingly proved to be correct, but even the said geologists themselves are unable to satisfactorily answer that this prediction was made on solid scientific grounds. Like Turkey, Syria is also facing major devastation as a result of the recent earthquake.

Many areas of Pakistan are located on earthquake fault lines and earthquakes occur from time to time. Among them, the earthquake that occurred in Azad Kashmir and Khyber Pakhtunkhwa in 2005 was the most terrible, the day on which scientific research will make it possible to predict earthquakes and start warning in advance. On this day, man will be able to protect himself from the damage of earthquakes, but it is still not possible because scientists are unable to make any authentic prediction of earthquakes. No such system has been invented in the world so far, which can detect the earthquake in advance. It is a fact that natural disasters and accidents occur in the history of nations and every nation tries to deal with these disasters and accidents according to its resources and planning, in order to prevent the damage caused by accidents and reduce the damage. can be reduced from

We should understand the message of nature hidden in these natural disasters that it is not enough for any country to get rid of earthquakes and floods, but the leaders in human history are the countries that learn from the difficulties faced while facing the situation. and build a plan of action on solid foundations to protect our people in the future. In view of these threats, a committee of scientists has agreed that we need to keep in mind the “worst-case scenario on Earth” for the protection and survival of this basic need, in which a major natural disaster occurs. Due to a disaster or a nuclear war, the land productivity of a country or region will completely disappear, a certain seed species will completely disappear from the world. On which effective decisions at the global level are necessary, so as to simultaneously ensure the overall security of humanity.

Most of the regions of the world are affected by earthquakes. Day by day it is known through the media that sometimes earthquakes and natural disasters occur in some countries. While our country still does not have all the facilities to deal with it, although experts have warned many times with their various concerns and analyzes regarding earthquakes and natural disasters. About the causes, triggers and causes of earthquakes, geologists say that our planet is always affected by earthquakes, but since the earth is very large, a large part of it is uninhabited and consists of seas, plains, deserts, rocks and Contains forests. So we remain unaware of these day-to-day earthquakes, but when these earthquakes hit urban populations, they make history.

Earthquakes occurring on land are generally of two types, the first cause is volcanic mountains whose eruptions do not produce much earthquake intensity. Most of the destruction comes from the second type of earthquake and despite all its progress, man has not discovered a timely prediction system for this sudden disaster and is still helpless in the 21st century in front of this act of nature. Actually the earth we live on has many layers in its internal structure. In which there are soft and hard rocky layers. Even the slightest movement of underground rocky rocks causes the upper surface of the earth to rise and fall.

Earthquakes that often occur are caused by underground rocks slipping, which shakes the buildings and houses on the upper surface of the earth. If we try to understand the nature of earthquakes, it is found that according to experts, earthquakes There are two types of and as far as seismic waves are concerned. Its sudden movement creates seismic waves. When these waves pass through the Earth’s rocks, they add stress to them, which creates strain. When the wave passes, that is, the stress disappears, the strain disappears and the rock formation returns to its original volume and shape. .

Waves are divided into three types primary, secondary and superficial. Primary waves, being the first, are faster than other seismic waves. As primary waves pass through a medium, the components of the medium move rapidly back and forth along the path of the wave. The speed of this wave is one and a half kilometers per second in water and thirteen kilometers per second in land. The second type is secondary waves, whose intensity is less than primary waves. The third are surface waves, they occur in the upper surface of the earth and disappear as they go deeper.

There are two more types of surface waves. In the first type, vibrations are generated and travel along the surface of the earth. In the second type, the waves move in the form of circles like ocean waves. At this time, the subcontinent’s land plate is moving northward three to four centimeters per year towards the Asian plate. This process has been going on for a long time. Once the distance of Pakistan from the center of the earthquakes was 380 km, which is now seventy to ninety km. The area between them has turned into mountains.

The Himalayas, Hindu Kush and Karakoram are the cause of this chain. When such pressures build up inside the earth, energy will be stored which will be released later. In this context, it is important to be careful about where the fault is passing. In other words, instead of constructing buildings, pastures and parks should be built there, so that in the event of an earthquake, loss of life and property will be minimized. And underground rocks are changing their position.
