What do you mean by engineering seismology?

Engineering Seismology is the study of Seismology as related to Engineering. The seismic hazard at a site cannot be controlled. It can only be assessed. In the same context, Earthquake Engineering is the subject of analysis and design of structures to resist stresses caused by the earthquake ground motion.

What is the importance of engineering seismology?

Engineering seismology lays the bases for calculating seismic hazard, and includes producing catalogues of historical and instrumental earthquakes, reliable ground motion mitigation models and high-definition geological underground models and interpreting historical accounts.

What is seismology in civil engineering?

Importance of seismology in civil engineering practice Seismology is study of the generation, propagation and recording of the elastic waves and the source that produce them. This is essential for the proper location, planning, design, construction, operation and maintenance of engineering structures.

What are the seismic waves?

A seismic wave is an elastic wave generated by an impulse such as an earthquake or an explosion. Seismic waves may travel either along or near the earth’s surface (Rayleigh and Love waves) or through the earth’s interior (P and S waves).

Who is the father of seismology?

John Milne: Father of Modern Seismology.

What is studied in seismology?

Seismology is the science of earthquakes to study the causes and effects of minute pulsation to most catastrophic natural phenomenon inside the earth.

What are the 4 main types of seismic waves?

Love Waves—surface waves that move parallel to the Earth’s surface and perpendicular to the direction of wave propagation..

P-wave Motion. P-wave:the primary body wave; the first seismic wave detected by seismographs; able to move through both liquid and solid rock.
S-wave Motion.
Rayleigh-wave Motion.
Love-wave Motion.

What are the 3 types of seismic waves?

There are three major kinds of seismic waves: P, S, and surface waves. P and S waves together are sometimes called body waves because they can travel through the body of the earth, and are not trapped near the surface. A P wave is a sound wave traveling through rock.

Where does earthquake happen?

The Earth’s crust (the outer layer of the planet) is made up of several pieces called tectonic plates and most earthquakes occur along their edges. The plates under the oceans are called oceanic plates. Plates that are not under the ocean are continental plates.

What are the elements of seismology?

SEISMOLOGY. Conversely, an element G ! of the stress tensor is deﬁned as the component of the traction acting on the surface perpendicular to the axis ( P ( G # 3 P (& (4.8) The 9 components G ! of all tractions form the elements of the stress tensor: G # 3 G O O ; 9 ; O ;; G 9 O ;

What are the components of engineering earthquake science?

ELEMENTS OF ENGINEERING SEISMOLOGY I. Studying earthquake history and tectonics to assess the earthquakes that could occur in a region and their characteristics and frequency of occurrence. II. Studying strong ground motions generated by earthquakes to assess the expected shaking from future earthquakes with similar characteristics.

What is the scope of Engineering Seismology?

It generally applied to the branch of seismology that deals with the assessment of the seismic hazard of a site or region for the purposes of earthquake engineering. It is, therefore, a link between earth science and civil engineering. There are two principal components of engineering seismology.

What is a seismograph?

•Seismograph:- A recording of earth motion as a function of time. 4. Engineering seismology:- Engineering seismology is the study and application of seismology for engineering purposes.
