Abstract

The near-surface is the subject of all three branches of seismology --- earthquake seismology, exploration seismology, and engineering seismology. The difference is not just a matter of scale, but also the nature of seismic wave propagation. 

The narrow scope of engineering seismology includes its application to geotechnical site investigations, and seismic microzonation to determine soil amplification and liquefaction susceptibility within a municipal area to estimate the earthquake risk. The broad scope of engineering seismology also includes its application to groundwater exploration, coal and mineral exploration, geothermal exploration, and investigations of historical buildings and archaeological sites. This course is devoted to application of the seismic method to delineate the near-surface geology primarily for geotechnical remediation of the soil column for civil engineering structures. Nevertheless, the course also includes case studies for the broader scope of engineering seismology.

Summary

The following topics will be addressed in this course:

Seismic waves: body waves, surface waves, the dispersion spectrum, and Rayleigh-wave dispersion
Seismic modeling of the soil column: P-wave velocity estimation, shallow seismic imaging, S-wave velocity estimation, borehole velocity measurements, and correlation of seismic velocities with geotechnical borehole data
Site characterization: five case studies
Landslide investigations: hydroelectric dam project site, refinery project site, and residential housing project site
Active fault investigations: nuclear power plant project, refinery project, and subsea road tunnel project
Seismic microzonation: refraction seismic survey and reflection seismic survey
Geophysical investigations of historic buildings: the Great Church of St. Sophia, the Mosque of Sultan Mehmet, the Church of the Holy Savior in Chora, and the Bridge of Emperor Justinianus
Exploration of earth resources: groundwater exploration, coal exploration, mineral exploration, and geothermal exploration

Who should attend?

Geophysicists, geotechnical engineers, earthquake engineers, and engineering geologists.

Course objectives

A review of seismic wave propagation and a comprehensive survey of shallow seismic imaging, P- and S-wave velocity estimation for seismic modeling of the soil column, and case studies to demonstrate the power of the seismic method to solve engineering problems --- landslide investigations, soil amplification, liquefaction, active-fault investigations, seismic microzonation, geophysical investigations of historic buildings, and earth resource exploration.
