Seismologists are the scientists that study earthquakes and the related activities to earthquakes. The composition and structure of the earth is also a part of what seismologists research.
Seismologists use instruments to gather data and monitor the activity of the Earth's crust. This profession also monitors the activities that result from an earthquake. This includes tsunamis, volcanoes, oceanic activity and atmospheric processes.
To become a seismologist, a bachelor degree is required. The degree is usually in a geophysics-related field. To further a career in this industry, a graduate degree may be required. Seismologists perform the majority of their work in laboratories and offices but also explore sites of seismic activity.
