A 4.0 magnitude earthquake hit Delhi and NCR on February 17, 2025, causing noticeable shaking and prompting residents to ...

The seismicity, or the frequency of earthquakes, around Delhi might be associated with the Delhi-Haridwar Ridge, a “major ...

Seismic surveys can produce EWs when the shear wave velocity of one layer is substantially lower than the velocity of the layer above it. The mode shape analysis is consistent with periodicity, as ...

Seismometers detect ground motion caused by seismic waves, providing data on the location, magnitude, and depth of earthquakes. GPS stations measure ground displacements that can indicate tectonic ...

In the early hours of 17 February 2025, an earthquake with a magnitude 4 occurred near Jail Park in Dhola Kawan, New Delhi, ...

Suppose a train is coming, as it gets closer, the sound gets louder. In the same way, when an earthquake occurs, seismic waves travel through the ground, producing vibrations that can be heard.” ...

Those older rocks are harder and denser, making it easier for seismic waves to travel across them. In the West, faults are newer and absorb more of the seismic wave energy, so earthquakes don’t ...

“When earthquake waves (shaking) reach the surface, they can be transferred to the air and become sound waves,” Coulson said in an email Monday afternoon. “Then we can often hear the sound ...
