How many times does an earthquake occur in a year
According to the information, about 20 thousand earthquakes occur every year across the world. Earthquakes occur more frequently than Some of these earthquakes are so minor that they are not even recorded on the seismograph. At the same time, some are so powerful that they cause destruction. Let us tell you that the cause of earthquake is said to be the turmoil within the earth. It is also a fact that these earthquakes occur in lakhs of cases, but most of the earthquakes are mild and remain undetected. Reasons for earthquakes. >
There is always turmoil under the surface of the earth or inside the earth. The plates present inside the earth are constantly colliding with each other or moving away. Due to this, earthquakes keep occurring every year. Before understanding earthquakes, we must understand the structure of the plates present beneath the earth. An expert told that there are 12 tectonic plates in the earth. The energy released when these plates collide with each other is called an earthquake.
What is the epicenter of an earthquake?
Tell Let us tell you that the place under the earth’s surface where rocks collide with each other or break. Is called the epicenter of the earthquake. It is also called hypocentre. From this center itself, energy spreads in the form of waves and vibrations and earthquakes occur. This vibration occurs in exactly the same way as waves spread when a stone is thrown into a still pond. According to science, the place where the line connecting the center of the Earth and the epicenter of an earthquake intersects the Earth’s surface is called the epicenter or epicenter of the earthquake.
< strong>Why do rocks break?
You have read in science that the earth is made up of seven landmasses. These landmasses are the Pacific Ocean landmass, the Indian-Australian landmass, the North American landmass, the South American landmass, the African landmass, the Antarctic landmass and the Eurasian landmass. The rocks under the earth remain under pressure. When this pressure exceeds a limit, the rocks suddenly start breaking. Due to this change the energy present for years gets released. Due to this energy the rocks break like a weak surface.
Where do most earthquakes occur?
Indonesia has the most earthquakes in the world. Coming to India, this country is located in the Ring of Fire. Due to which more earthquakes occur here. Apart from this, Java and Sumatra also fall in this region. This area located near the Pacific Ocean is said to be the most dangerous region of the world.
Into how many zones are earthquakes divided?
In terms of earthquakes India has been divided into 5 zones. Let us tell you that the areas have been kept according to the danger of earthquake. Areas in Zone 5 are most at risk from earthquakes, while areas in Zone 1 and 2 are at least at risk. The fifth zone covers 11 percent of the total area of the country, while the fourth zone covers 18 percent. Whereas 30 percent of the country falls in the third and second zones.
Which is the safest place?
The area of Zone 1 is the safest in terms of earthquakes. Is considered safe. The probability of earthquake occurring in this area is very less. Zone-1 includes Western Madhya Pradesh, Andhra Pradesh, Karnataka, Eastern Maharashtra and Odisha. Whereas earthquake Zone 2 is considered to be the least dangerous area, it includes Rajasthan, Tamil Nadu, some part of Madhya Pradesh, West Bengal and Haryana.
The highest danger from earthquake.
If we talk about the most dangerous areas in the country, then these include the cities falling in Zone-5. Kutch of Gujarat, Uttaranchal and North-Eastern states come in this area. There is a risk of earthquake in Zone-4 also, although it is less as compared to Zone-5. This area includes big cities like the capital Delhi, Mumbai as well as Jammu and Kashmir, western Gujarat, Himachal Pradesh, Uttaranchal, hilly areas of Uttar Pradesh and many areas of Bihar-Nepal border.
