1
Q

A
Refers to relatively persistent vibration of the ground due to many causes – It is basically an unwanted component of signals recorded by a Seismometer
2
Q
What are the root causes of this noise ?
A
Transport, manufacturing activities. These make study of seismic data harder for scientists
3
Q
Applications of seismic noise ?
A
Oil exploration, hydrology and earthquake engineering
4
Q
Context ?
A
It is found that due to COVID 19 crisis and lockdown , there has been a sufficient decline in the levels of seismic noise vibrations
