Seismologist Job Description

     Seismologists are Earth scientists who specialize in geophysics. They study seismic waves, which are waves of energy that can either be caused by rock suddenly breaking apart within the earth's crust or by tectonic plates sliding. These events are commonly known as earthquakes. Some seismologists work in laboratories and on research sites, while others work in offices to interpret data.

     Seismologists also monitor active volcanoes to look for signs that could indicate an upcoming eruption. They use seismographs, computer equipment and other tools to help them analyze data about shifts that occur within the earth's crust. Seismologists study the geological makeup and structure of the earth and their research has played a vital role in the development of tsunami warning systems and many other major developments. 

     It is common for seismologists to work in the petroleum industry, where they monitor seismic waves from controlled sources such as vibrations from trucks and explosions. The information that they collect helps them search for sources of natural gas and petroleum that may be found underground.

  
     Seismologists may also observe earthquakes and volcanoes to study naturally occurring seismic waves. They investigate the results of earthquakes such as tsunamis and landslides. They help warn and protect the public and reduce future risk by predicting any future harmful geological events. They do this by interpreting the data they collect and by conducting hypothetical research based on the structures of the Earth. 

    Seismologists also carry out field studies, where they gather samples of rock, then analyze the samples in a lab. They also examine air photos, rock samples, and other information to help them evaluate the vibrations of the Earth.
