What is seismology

Groundwater levels in wells can oscillate up and down when seismic waves pass. The water level might remain higher or lower for a period of time after the seismic waves end, but sometimes a long-term offset of groundwater levels follows an earthquake. The largest recorded earthquake-induced offset in a well is a one meter rise.

Seismology Meaning. It is a separate branch of Geology or Science that deals with earthquakes. It is a scientific and interdisciplinary subject that studies earthquakes and their related concepts. This term is made up of two words ie. Seismos means earthquake and logy mean study. Thus, this term refers to the study of earthquakes.Seismic reflection images show a great diversity, but the most persistent feature is a highly reflective crust that is underlain by a seismically transparent upper mantle (Fig. 8).The reflective crust is largely due to lithological layering and shear deformation in the crust, and the Moho correlates with the termination of this feature in seismic records.A seismograph is a device for measuring the movement of the earth, and consists of a ground-motion detection sensor, called a seismometer, coupled with a recording system.
