Seismology is a branch of geophysics that combines physics and geology. It involves monitoring seismic activity globally using a network of seismograph stations. Seismologists study the causes of earthquakes (tectonics), the behavior of seismic waves as they travel through different mediums and the effects of earthquakes on human structures. Beyond just disaster management, seismology is used in the oil and gas industry (Seismic Reflection) to find underground resources. It is the only science that allows us to “see” deep into the Earth, providing the evidence needed to support theories like Plate Tectonics and the existence of a liquid core.
