Why does an earthquake, what is the Richter scale and how much intensity shock can cause damage? Know the full math here…
Ever since the earthquake in Turkey and Syria caused havoc, people trembled in the name of an earthquake। As soon as the late Tuesday night, people came out of their homes after feeling the tremors of earthquakes in many parts of Delhi-NCR and Punjab Samet country
New Delhi: Late-night earthquake tremors were felt in many parts of the country including Delhi-NCR। The epicentre of the earthquake was in Hindukush, far from Afghanistan। The magnitude of the earthquake on the Richter scale is stated to be 6.5। An earthquake of such intensity on the Richter scale is considered quite dangerous। Earthquake tremors were felt in many cities in India, Afghanistan and Pakistan। However, no loss is reported yet। But after the devastation in Turkey and Syria, people are very much nervous about this earthquake। Today, in this article, you know why earthquakes eventually occur and how their intensity is measured and how much intensity earthquakes can cause damage.
Earthquake comes from hitting plates
This earth is mainly made up of four layers, called inner core, outer core, mantal and crust। The crust and upper mantle are called lithospheres। These are thick layers of 50 kilometers, called tactic plates। These tactic plates move from their place, rotate, move। These plaits move from their location to about 4-5 mm every year। These can move from their place both horizontally and vertically। In this order, if a plate goes near another plate, it goes away। During this time sometimes these plates collide with each other। In this case, an earthquake occurs and the earth is shaken। These plates are about 30–50 km below the surface.
Center and intensity of geomorphism
The epicenter of an earthquake is the place just below which the stir in the plates emits geological energy। At this place, the vibration of the earthquake feels more। The frequency of vibration goes away, its effect decreases। Its intensity measures the Richter scale। If an earthquake of 7 or more magnitude occurs on the recumbent cell, the shock is intensified within the radius of 40 km। But it also depends on whether the seismic frequency is upward or in the realm। If the frequency of vibration is upward then the effect area is low। The deeper the earthquake, the less its intensity is felt on the surface.
What is the Richter scale?
Richter scale is used to measure earthquake intensity। It is also called Richter Magnitude Test Scale। The Richter scale measures earthquake waves from 1 to 9। The Richter scale was discovered in 1935 by Charles Richter, a scientist working at the California Institute of Technology, in collaboration with Beno Gutenberg। The magnitude of the earthquake on the Richter scale can be gauged from the fact that an earthquake on the 8 Richter scale can generate energy from 60 million tons of explosives.
Relation of Richter scale and earthquake intensity?
- Only the seismograph shows when an earthquake strikes the 0 to 1.9 Richter scale.
- There is light vibration when earthquakes occur on the 2 to 2.9 Richter scale.
- A truck passes near you when an earthquake strikes a 3 to 3.9 Richter scale, such an effect.
- Windows can be broken when earthquakes occur on the 4 to 4.9 Richter scale। Tungie frames may fall on the walls.
- Furniture can move when earthquakes occur on the 5 to 5.9 Richter scale.
- The foundation of buildings can be cracked when earthquakes occur on the 6 to 6.9 Richter scale। Damage to the upper floors may occur.
- Buildings collapse when earthquakes occur on the 7 to 7.9 Richter scale। Pipes burst inside the ground.
- Large bridges, including buildings, also collapse when earthquakes occur on the 8 to 8.9 Richter scale.
- Complete devastation when earthquakes occur on the Richter scale at 9 and above। If someone is standing in the field, he will be seen waving the earth। Tsunami if close to the sea। In an earthquake, every scale of the Richter scale is 10 times stronger than the previous scale.
Why does an earthquake, what is the Richter scale
An earthquake occurs when the Earth’s crust suddenly shifts, releasing energy in the form of seismic waves that propagate through the ground. This can be caused by a variety of natural and human-made factors, such as tectonic plate movements, volcanic activity, or underground explosions.
The Richter scale is a measure of the magnitude or strength of an earthquake, based on the amplitude of the seismic waves it generates. The scale was developed by Charles Richter in the 1930s and is logarithmic, meaning that each increase in one unit represents a ten-fold increase in the magnitude of the earthquake. For example, an earthquake with a magnitude of 7.0 is ten times stronger than one with a magnitude of 6.0.
Some unique points about earthquakes and the Richter scale include:
- Earthquakes can vary in size and intensity, from small tremors that go unnoticed to catastrophic events that cause widespread damage and loss of life.
- The Richter scale is not the only way to measure earthquakes; other scales such as the Moment Magnitude scale are also used by seismologists.
- The largest earthquake ever recorded on the Richter scale was the 1960 Valdivia earthquake in Chile, which had a magnitude of 9.5.
- Even small earthquakes can have aftershocks that can cause additional damage and disruption.
- Earthquakes can trigger other natural disasters such as landslides, tsunamis, and volcanic eruptions.
- Understanding earthquakes and their impact on society is an important area of study for geologists, engineers, and emergency management professionals.
- The intensity of an earthquake can vary depending on factors such as the distance from the epicenter, the depth of the earthquake, and the type of rock or soil in the area.
- Seismographs are used to detect and measure earthquakes. These instruments detect seismic waves and record them as a seismogram, which can be used to determine the earthquake’s location, magnitude, and other characteristics.
- Earthquakes can occur anywhere in the world, but certain regions are more prone to earthquakes than others. These include areas along the Pacific Ring of Fire, the Mediterranean region, and the Himalayas.
- Earthquakes can have long-lasting impacts on communities, including damage to buildings and infrastructure, disruptions to transportation and communication networks, and economic losses.
- The Richter scale is named after Charles Richter, a seismologist who developed the scale in collaboration with Beno Gutenberg in the 1930s. The scale was originally intended for use in southern California but has since been adopted as a standard for measuring earthquakes worldwide.
- The Richter scale has been criticized for being limited in its ability to accurately measure very large earthquakes. For this reason, other scales such as the Moment Magnitude scale have been developed to better measure the energy released by earthquakes.
- Earthquakes can be predicted to some extent, but predicting the timing, location, and intensity of an earthquake with complete accuracy remains a challenge for scientists.
