Earthquake tremors in Chamba, Himachal, intensity was 5.3 on Richter scale; people out of fear

Read Time:3 Minute, 49 Second

A strong earthquake was felt in Chamba district of Himachal Pradesh at 9:35 pm on Thursday. After the sudden earthquake, people were evacuated from their homes and reached open spaces. The intensity of the earthquake was estimated at 5.3 on the Richter scale. There is no information about any casualty in the district due to the earthquake. Appropriate Chamba Mukesh Rapswal said that there was no loss of life or property in the district due to the earthquake.

Earthquake tremors felt in Kullu-Lahaul also Several earthquakes were felt one after the other in Kullu and Lahaul valley. People came out of their houses after three to four tremors of the earthquake that occurred around 9:35 pm. In Keylong, people came out with their children in the extreme cold. Whereas in Manali and Kullu people came out of their homes. Gurdev Kumar said that he came out of the house with his granddaughter. ADM Kullu Ashwani Kumar said that there have been earthquake tremors. But there is no news of damage from anywhere.

A devastating earthquake occurred today in the year 1905.

More than 20 thousand human lives were lost in the earthquake of magnitude 7.8 that occurred in Kangra on the morning of April 4, 1905. Nearly one lakh buildings in and around Kangra were destroyed by the earthquake, while more than 53 thousand cattle also became victims of the earthquake.

Why do earthquakes occur?

There are seven plates inside the Earth, which keep rotating continuously. The zone where these plates collide is called fault line. The corners of the plates bend due to repeated collisions. When too much pressure builds up, the plates start breaking. The energy below finds a way out and after the disturbance an earthquake occurs.

The “center” of an earthquake, also known as the hypocenter or focus, refers to the point within the Earth where the seismic energy is released or originates. This point is usually located beneath the Earth’s surface along the fault line where the earthquake occurs.

What does the center and intensity of an earthquake mean?

The “intensity” of an earthquake refers to its severity or strength, typically measured using scales such as the Richter scale or the moment magnitude scale. Intensity indicates the amount of energy released by the earthquake and the level of ground shaking experienced at different locations. It takes into account factors such as the distance from the epicenter, the depth of the earthquake, and the local geology. Higher intensity earthquakes are associated with more severe ground shaking and greater potential for damage to structures and infrastructure.

How is the intensity of earthquake measured and what is the measuring scale?

The intensity of an earthquake is measured using various scales, with the most commonly known ones being the Richter scale and the moment magnitude scale (Mw). These scales quantify the amount of energy released by an earthquake and the level of ground shaking experienced at different locations. Here’s a brief overview of each scale:

Richter Scale: Developed by Charles F. Richter in 1935, the Richter scale measures the magnitude of an earthquake based on the amplitude of seismic waves recorded by seismographs. The scale is logarithmic, meaning that each whole number increase on the scale represents a tenfold increase in the amplitude of ground motion and approximately 31.6 times more energy release. For example, an earthquake with a magnitude of 7.0 releases approximately 31.6 times more energy than one with a magnitude of 6.0. The Richter scale is most commonly used for smaller earthquakes.
Moment Magnitude Scale (Mw): The moment magnitude scale is a more modern and widely used scale for measuring earthquake magnitude. It measures the total energy released by an earthquake, known as seismic moment, which takes into account the area of the fault rupture, the average amount of slip, and the rigidity of the Earth’s crust. The moment magnitude scale provides a more accurate measure of earthquake size, especially for larger earthquakes, and is less susceptible to saturation effects than the Richter scale.

Both scales are logarithmic, meaning that each unit increase on the scale corresponds to a tenfold increase in the amplitude of ground motion and approximately 31.6 times more energy release. However, the moment magnitude scale is considered more accurate and reliable for measuring larger earthquakes and is the preferred scale used by seismologists and earthquake researchers today.
