Earthquakes in the country four times: What causes earthquakes and how is their intensity measured? Know all the information

Earthquake in Delhi NCR: Major earthquake tremors were felt in North India including Delhi-NCR on Tuesday. The tremors were so strong that people came out of their homes and offices. Earthquakes occurred not once or twice but four times on Tuesday. In which the intensity of earthquake is 2.7, 3.0, 4.6 and 6.2. Apart from this, earthquake tremors were felt in four states of North East including Assam and Meghalaya yesterday. Apart from this, earthquake also occurred in Tripura and West Bengal yesterday evening. Then let us know why earthquakes occur and how their intensity is measured…

Why do earthquakes occur?

There are a total of seven plates inside the Earth. Which is always working. The place where these plates collide is called a fault zone. When these plates collide, energy tries to escape. These plate movements become earthquakes. The closer the epicenter of an earthquake is to the surface, the more devastation it causes.

What type of earthquake is felt and how intensely?

If the intensity of the earthquake is 0 to 1.9 Richter then it is not felt. This information is obtained from seismograph. At the same time, mild tremors are felt at 2 to 2.9 Richter. Apart from this, if its intensity is 3 to 3.9 then some more tremors are felt. Furthermore, a magnitude of 4 to 4.9 Richter can cause windows to break, while a magnitude of 5 to 5.9 Richter can cause objects and fans to shake. When the intensity of the earthquake is 6 to 6.9, there may be cracks in the foundation of the houses and when the intensity reaches 7 to 7.9, the houses may collapse and cause huge destruction. And if an earthquake of 8 to 8.9 magnitude occurs, there is a danger of tsunami. If the intensity of the earthquake is 9 then the earth appears to be shaking.

Does climate change affect earthquakes?

A study shows that our changing climate affects not only hazards on the Earth’s surface, but also hazards such as earthquakes and volcanic eruptions beneath the Earth’s surface due to climate change and particularly increased rainfall rates and melting of glaciers. Can increase. The Intergovernmental Panel on Climate Change Sixth Assessment Report 2021 shows that average rainfall has actually increased since 1950 in many regions of the world. Warmer climates can hold more water vapor, leading to heavier rainfall. Geologists have long researched rainfall rates and earthquake activity. This shows that earthquakes keep occurring in the Himalayas throughout the year. Research shows that 48 percent of earthquakes in the Himalayas occur in the dry and pre-monsoon months of March, April and May, while only 16 percent occur during the monsoon season.
