However, one of the most shocking aspects which was noticed along with the earthquake was the sound. Here are all the details regarding how an how earthquakes occur and the types of seismic waves associated with them.

What is an Earthquake?

An earthquake is what happens when two blocks of the earth suddenly slip past one another, causing a vibration of the earth’s surface.

According to the US Geological Survey, the shallower an earthquake is, the more energy reaches the surface. High-frequency seismic waves travel through the ground, which is why thunder-like sounds are often heard during an earthquake. These seismic waves typically have frequencies ranging from 0.1 to 3.5 Hz.

Earthquake movement: Types of waves

• P-waves travel the fastest and create a sensation similar to a sudden blow or bang.
• S-waves move more slowly and typically cause a rolling or swaying motion.
• Surface waves occur only during large earthquakes, moving the Earth from side to side or causing the ground to ripple like ocean waves.

Is the World ending?

Coming to the point whether this earthquake is a sign of the end of the world, strong earthquake tremors accompanied by loud rumbling are very common and are not a cause of worry. The sudden shaking of the ground and thunder-like sounds have left many fearing a disaster but there is no reason to worry. Scientists, who are experts on earthquakes, have explained that shallow earthquakes release more energy, making them feel more intense on the surface, causing the sound.

Earthquake hits Delhi, tremors felt across NCR

An earthquake of 4.0 magnitude rocked parts of Delhi-NCR early on Monday, the National Center for Seismology said. There were no immediate reports of any damage or injuries. The earthquake, with its epicentre in New Delhi, struck at a depth of five kilometres at 5:36 AM, it said in a post on X. The epicentre was near Durgabai Deshmukh College of Special Education in Dhaula Kuan, an official told news agency PTI.

That region, which has a lake nearby, has been experiencing smaller, low-magnitude quakes once every two to three years. It recorded an earthquake of 3.3 magnitude in 2015, he said. A loud sound was also heard when the earthquake hit, the official added.
