Seismology and Earthquake Engineering Quiz

Module 1 CE 415c – EARTHQUAKE ENGINEERING: Chapter 1 - Seismology

• Seismology is the study of seismic waves and their generation, propagation, and measurement through the Earth.
• The word seismology comes from the Greek words "seismos" meaning earthquake and "logos" meaning science.
• Seismic wave propagation provides valuable information about the internal structure of the Earth.
• The learning outcomes of this module include identifying the Earth's internal structure, understanding plate boundaries and motion, and recognizing local plate boundaries.
• The Earth's shape is an oblate spheroid with a diameter of approximately 12,742 kilometers.
• The Earth's internal structure consists of the crust, mantle, outer core, and inner core.
• Plate boundaries are areas where tectonic plates interact, and their movement is responsible for earthquakes.
• There are three types of plate motions: convergent, divergent, and transform.
• Convergent plate boundaries occur when two plates collide, resulting in subduction zones or mountain ranges.
• Divergent plate boundaries occur when two plates move away from each other, creating rifts and mid-ocean ridges.
• Transform plate boundaries occur when two plates slide past each other horizontally, resulting in earthquakes.
• It is important to understand plate boundaries in the local area to assess the seismic hazard and potential for earthquakes.
