  6. Characteristics of strong motion: amplitude, duration and frequency
  7. Seismic hazard
  8. Local site effects
  9. Seismic risk: Vulnerability, exposure and hazard


What is engineering geology?

Seismology is study of the generation, propagation and recording of the elastic waves and the source that produce them.

Engineering geology is the application of geological data, techniques and principles to the study of rock and soil surfacing materials, and ground water. This is essential for the proper location, planning, design, construction, operation and maintenance of engineering structures.

Importance of engg geology in Civil Engineering practice


What does Engineering Geology study?

Rock, soil, water and the interaction among these constituents, as well as with engineering materials and structures.



Why to study Engineering geology?

Serve civil engineering to provide information in 3 most important areas:
  1. Resources for construction; aggregates, fills and borrows.
  2. Finding stable foundations
  3. Mitigation of geological hazards; Identify proplems, evaluate the costs, provide information to mitigate the problem
