Seismology

What is Seismology

Seismology in the simplest terms is defined as the study of earthquakes. In the present Times, advancement is taking over every sector rapidly. To process that advancement into an establishment, we are directly or indirectly taking up and utilising the abundance of natural resources. These natural resources are limited in nature and are bound to deplete. Sometimes this whole charade disrupts the balance of the Earth's atmosphere and results in phenomena like earthquakes. 

Seismology is that branch of geophysics which is concerned with everything related to earthquakes, including its cause, prevention, origin, aftermath etc. Pursuing a career out of seismology will not only be beneficial to students but also contribute a great deal in the research attribute to decipher, anticipate and, measure the impact of an earthquake. 

This resolution will be useful in generating a capable-approach to earthquake-resistance practices. Students wanting to take up a career in seismology can pursue a postgraduate degree of Masters in technology from recognised institutes like IITs

Eligibility Criteria (UG & PG) of Seismology

The basic requirement for entry into any Engineering college for Seismology course is almost the same across all institutions. There are certain mandatory terms that are required to be followed. 

Eligibility criteria for Undergraduate seismology Course 

  1. Effective completion of class 12th as part of the non-medical stream from a recognised board with subjects such as physicschemistry, and mathematics. 

  2. 40-50 percent is the minimum aggregate mark needed to appear for the entrance examinations. 

  3. For seismology courses, undergraduate degrees vary from B.sc to BE and B.Tech. The topics therefore oscillate between PCM and geology

  4. Some universities are subject to an entrance test and any prospective applicant is expected to meet the minimum cut-off prior to the start of the admission process.

Eligibility criteria for postgraduate seismology courses 

  1. For admission to courses such as M.TechM.Sc. Applicants should have obtained a bachelor's degree from a recognised institution in the line required, along with ME.

  2. In the bachelor's degree with mathematics, geology and other related subjects, candidates should have scored at least 50 percent overall.

  3. State-level and national level entrance exams for aspiring candidates are held annually. Some of these admissions have similar requirements for eligibility across all universities.

  4. Most universities often make it obligatory after the acceptance of the entrance examination for the applicant to appear for a personal interview.

Seismology course entrance exam 

1. JEE Main And JEE Advanced

The Joint Entrance Test is a test carried out at the national level to obtain admission to different courses in undergraduate engineering and architecture. 

2. GATE

Graduate Aptitude Test In Engineering is a popular national level test conducted annually to test engineering aptitude of individuals who want to gain admission to postgraduate engineering courses like seismology. In September, the applications usually begin.

Scope of Seismology in India and Abroad

Pursuing a course in seismology moves toward a plethora of scope because this specialisation in geophysics is a branch of applied Sciences pertaining to natural environment phenomena. 

There are a wide number of National International Organisations constantly researching and developing studies related to the Earth's surface. 

The scope of pursuing this course expands a great deal to foreign countries where natural phenomena like earthquakes are more frequent. 

This course is greatly suitable for candidates who have an interest in finding data about earth surface like seismic sensors and natural resource deposits under land in the sea region. 

Not only this but the candidates pursuing this course also develop highly specialised knowledge in other subjects of Applied Sciences like sedimentology, hydrogeology, and geochemistry which helps in further widening the scope of this course as well as increasing its popularity among people. 

Course Subjects

The subjects taught under seismology are highly related to subjects taught under earthquake engineering. Sometimes the subjects vary from one university to another, but the core subjects remain the same. 

These subjects are a perfect blend of Technical and scientific as well as theoretical and practical knowledge. 

Some of the major elective start under seismology are given as follows: 

  1. Seismological Modelling And Simulation

  2. Vulnerability And Risk Analysis

  3. numerical Methods Of  Dynamic Systems

  4. Ground Shaking Hazard

  5. Evaluation And Retrofitting Of Structures

  6. Advance Seismic Microzonation

  7. systematic Disaster Mitigation And Management

  8. Ground Failure Hazard

  9. Earthquake Precursors And Early Warning System

  10. Geoinformatics

  11. Information And Model Testing Techniques

  12. Strong Motion Seismology

  13. Ground Improvement Techniques 

Careers in Seismology

There is a wide potential growth in seismology which has opened the doors of the career path of students pursuing this branch of geophysics.

Students can opt for diverse career choices because along with seismology candidates pursuing geophysics and geosciences have exposure and knowledge of other related subjects like Oceanography, mineral and mining. 

The study of this subject is also beneficial in providing the candidates with the change of working in various Laboratories, institutions, government Ministries, as well as international organisations. 

Job Profiles and Top Recruiters

Since seismology holistically deals with studying about phenomena taking place inside the Earth's crust, the major part of the work revolves around researching. 

However, this research line may vary from one job profile to another and one company to another. 

In the same industry of seismology, there are many roles available like attending conferences and publishing the findings, scrounging natural resource deposits under the Earth's surface, evaluating seismic stations and developing early warning mechanisms. 

Candidates can choose their work line according to their expertise and interest. 

Candidates also almost always have the option of getting into Technical content writing about geophysics and geoscience as well as work as a professor or a lecturer and teach subjects like environmental science, seismology, geology, mathematics, geosciences etc. Some job profiles offered by few known brands and companies are mentioned below:

Required Skillset for Seismology

The skills required for pursuing a career in seismology are quite diverse. The candidate should have analytical skills which are required in categorising the aspects particularly related to earthquake and review them with regards to the predetermined theories as well as find new ones. 

Candidates should also have a thorough scientific knowledge required in writing reports for R&D presentation. Communication skills are also required to educate people about the study findings in an interpretable manner. The basic skills required are, however, categorised into the following terms: 

  1. Research and Development: Candidates pursuing seismology must have a knack for digging deeper to improve and constantly revise the conventional approaches towards these phenomena which is why research and development skills are required as a crucial element of seismology. 

  1. Technical skills: Aspirants must possess technical skills in any branch of engineering since that is what the entire process depends upon. Without understanding the know-how behind naturally occurring things, it is impossible to study any subject further.

  2. Analytical skills: The quest of digging deeper in any subject does not just end at researching but also involves a great deal of critical evaluation and testing the finding against every theory. Hence, analytical skills are indispensable from the study of seismology.

Course Curriculum for Seismology

The curriculum for Seismology course differs across all institutions. A variety of subjects are taught under this course as it is a combination of technical and scientific knowledge. 

As we know, seismology is a part of a larger branch of Applied Sciences called geophysics, and any specialisation in this course can be pursued only with a doctorate. 

At undergraduate and postgraduate level this course comes under the umbrella branch extending up to two or four years respectively. 

The curriculum is divided subject-wise into electives like seismology, Atmospheric Studies, Oceanography, Mantel studies, etc.
