What is a Seismologist?

Seismology is the study of seismic waves, energy waves caused by rock suddenly breaking apart within the earth or the slipping of tectonic plates. We know these as events as earthquakes. They can also be caused by explosions from volcanic eruptions and testing of nuclear bombs. Seismology also studies seismic waves deliberately induced by controlled explosions, large trucks, and construction equipment, usually to search for underground sources of petroleum and natural gas.

Seismologists study earthquakes and their results, like tsunamis, and landslides. They may also monitor active volcanoes for tremors and signs of an impending eruption. They use seismographs and computer equipment to collect and analyze data on seismic events.

What Does a Seismologist Do?

Most seismologists work in petroleum exploration where they plan, generate, monitor, and analyze controlled seismic waves from explosions and vibrations from trucks. The information collected from the waves' movement and interactions with underground features help seismologists determine where oil and gas may be found.

Other seismologists study natural seismic waves related to hazards like earthquakes and volcanos, as well as their results, such as tsunamis and landslides. Some try to figure out why they last a certain amount of time, and how they stop. Some seismologists focus on geologic faults. They attempt to evaluate future risk and predict future destructive events. Their work helps protect the public through preparation, advisories, seismic zoning, and earthquake engineering. Maps of affected areas provided by seismologists can also help relief efforts after catastrophic events.

A few seismologists monitor for underground nuclear test explosions for intelligence agencies. Some use their knowledge to help unearth archaeological sites. Others conduct more theoretical research on the geological makeup and structures of the Earth.

Most seismologists plan and conduct field studies, where they collect samples and conduct site surveys. They then test the samples they collect in the lab. They also analyze air photos, well logs (geological notes made during drilling), rock samples, and other data to locate and assess underground oil and mineral resources. They make geologic maps, write reports, and present their findings to clients and colleagues.

Where Does a Seismologist Work?

Most seismologists, and 26% of geoscientists as a whole, are employed in oil and gas extraction. While the U.S. Bureau of Labor Statistics (BLS) doesn't report on seismologists specifically, it reports that another 16% of geoscientists were employed in engineering services as of 2012. 12% of geoscientists provided management, scientific, and technical consulting services. 7% worked in state government, and another 7% were employed by the federal government.

Seismologists studying large earthquakes often work in observatories or analysis centers with hyper-computing capabilities. These are usually run or supported by national governments. Smaller earthquakes are analyzed at regional research centers tied to university or government laboratories.

Most seismologists work full time and maintain a standard work week. However, long or irregular hours may be required when doing fieldwork, or during public emergencies caused by seismic events. They may need to travel often to reach field work sites, which can be sometimes be rustic.

What Is the Average Seismologist Salary?

BLS reports the average annual wage for geoscientists as a whole as $90,890 in May 2012. Those employed in oil and gas extraction earned the highest salaries ($137,750). Those working for the federal government made $94,830, and those providing engineering services made $74,360. Geoscientists employed in management, scientific, and technical consulting services earned $74,020, and those in state government made $62,030.

  • Foster a positive and safe work environment for mentor relationships and colleagues
  • Develop and report on project scopes, schedules, and budgets
  • Prepare technical reports; liaise with site stakeholders
  • Supervise fieldwork (survey, site recording, testing, monitoring, and data integrity) of multiple field crews
  • Communicate with funding agencies through grant applications
  • Communicate with stakeholders through field status reports and presentation of team findings
  • Oversee equipment and instruments

Ensure data integrity, quality assurance, organization, and appropriate tracking

What Is the Job Demand for Seismologists?

Employment of geoscientists overall is projected to grow 16 percent from 2012 to 2022, faster than the average for all occupations. Exploration for oil and gas, new drilling techniques, hydraulic fracturing, and increased interest in the environment will partly drive this growth. Geoscientists with master's degrees will have the best opportunities.

How Do I Get a Seismologist Degree?

Seismology is a field of geophysics. Most students earn bachelor's degrees in geophysics, geology, physics, or math. Geology, physics, math, and computer science are all important areas of study for future seismologists.

Advanced degrees are important for research positions. Most require a Ph.D. There are few graduate programs in geophysics; master's students typically study geology or physics.
