Chamba and Kangra districts are located in seismic zone V, which is classified as a high-risk area for earthquake damage. Due to the shallow depth of the recent earthquakes, the tremors were felt more intensely. Local officials reported that the district administration and relevant agencies are actively monitoring the situation.
Residents in Bharmour expressed heightened fear after experiencing three tremors within an hour. The sudden shaking caused panic, prompting many to rush out of their homes. For a time, they exchanged information about the earthquakes with each other, returning only once the situation normalized.
Understanding Earthquakes
Earthquakes occur due to the movement of seven tectonic plates within the Earth. The areas where these plates collide are known as fault lines. Repeated collisions cause the edges of the plates to bend, and when too much pressure builds up, the plates can break. The energy released during this disturbance leads to an earthquake.
Key Terms: Epicenter and Magnitude
The epicenter is the location directly above where geological energy is released due to plate movement, making it the point where tremors are strongest. As the distance from the epicenter increases, the intensity of the tremors generally decreases. However, earthquakes with a magnitude of 7 or higher on the Richter scale can produce strong tremors within a radius of 40 km, depending on whether the seismic frequency is upward or lateral. If the tremors are upward, a smaller area will be affected.
Measuring Earthquake Intensity
The intensity of an earthquake is measured using the Richter scale, also known as the Richter Magnitude Test Scale. Earthquakes are rated on this scale from 1 to 9, with measurements taken from the epicenter. The scale gauges the intensity of the energy released from within the Earth during an earthquake, providing an indication of the severity of the tremors.
- Chamba and Kangra districts are in seismic zone V, a high-risk earthquake area.
- Three earthquakes occurred within one hour, causing panic among residents in Bharmour.
- The tremors were felt intensely due to their shallow depth.
- Local officials are monitoring the situation actively.
