Earthquake Basics Presentation
Description.
A similar lecture featuring the USA's Pacific Northwest region is available from the Cascadia EarthScope Earthquake and Tsunami Education Program (CEETEP)
This resource is intended for introductory-level geoscience learners from secondary up to adult in a classroom or public lecture. Learners should have some knowledge of plate tectonics (ex. Alaska Plate Tectonics & Geohazards Presentation ). Although specific examples are from Alaska, much of the content is widely applicable.
Teaching Notes
- The slides contain a variety of notes to help users know the intention of the author.
- All the animations associated with the presentation are available above in a zipped file. The smaller animations are embedded within the PowerPoint but are provided again here in case there are any issues. The larger animations should be played outside of the PowerPoint as they is a bit too large to reliably embed. The logical place to do so is indicated in the pptx notes.

Earthquake Magnitude and Intensity. Magnitude is the measurement of the amount of energy released during an earthquake. The Richter scale is a numerical scale based on the size of the largest seismic waves generated by a quake that is used to describe its magnitude.

Presentation Transcript
Earthquake Magnitude and Intensity • Magnitude is the measurement of the amount of energy released during an earthquake. • The Richter scale is a numerical scale based on the size of the largest seismic waves generated by a quake that is used to describe its magnitude. • Each successive number in the scale represents an increase in seismic-wave size, or amplitude, of a factor of 10. • Each increase in magnitude corresponds to about a 32-fold increase in seismic energy.
How are the Size and Strength of an Earthquake Measured? • Magnitude • Richter scale measures total amount of energy released by an earthquake; independent of intensity • Amplitude of the largest wave produced by an event is corrected for distance and assigned a value on an open-ended logarithmic scale
Earthquake Magnitude and Intensity Modified Mercalli Scale • The modified Mercalli scale, which measures the amount of damage done to the structures involved, is used to determine the intensity of an earthquake. • This scale uses the Roman numerals I to XII to designate the degree of intensity. • Specific effects or damage correspond to specific numerals; the higher the numeral, the worse the damage.
Earthquake Magnitude and Intensity Depth of Focus • Earthquake intensity is related to earthquake magnitude. • The depth of the quake’s focus is another factor that determines the intensity of an earthquake. • An earthquake can be classified as shallow, intermediate, or deep, depending on the location of the quake’s focus. • A deep-focus earthquake produces smaller vibrations at the epicenter than a shallow-focus quake.
Classification According to Focus Depths
What are the Destructive Effects of Earthquakes? Damage in Oakland, CA, 1989 • Building collapse • Fire • Tsunami • Ground failure
Earthquake Destruction Amplitude, duration, and damage increases in poorly consolidated rocks.
EARTH DESTRUCTION Seiches - These are the rhythmic sloshing of water in lakes, reservoirs, and enclosed basins. The waves can weaken reservoir walls and cause destruction. Liquefaction - Unconsolidated materials saturated with water turn into a mobile fluid.
Earth Destruction • Landslides and ground subsidence – Whenever the land moves quickly, as with landslides, there is the potential for a lot of damage and potential loss of life. • Fire – Ruptured gas lines from earthquakes is one of the major hazards. • Ground shaking versus material type – More ground shaking occurs in poorly consolidated (loose) sediments than solid bedrock.
Earth Destruction Ground Rupture ‐ This refers to areas where the land splits apart causing a rupture. These are often long linear features.
Tsunamis • A tsunami is a large ocean wave generated by vertical motions of the seafloor during an earthquake. • These motions displace the entire column of water overlying the fault, creating bulges and depressions in the water. • Long waves that can travel at speed over 800 km/h (500 mph). • When the waves enter shallow water they may form huge breakers with heights occasionally exceeding 30 m (19 ft.).
Formation of a Tsunami Tsunami waves can travel at a speed of over 500 mph.
Can Earthquakes be Predicted? Earthquake Precursors • changes in elevation or tilting of land surface, fluctuations in groundwater levels, magnetic field, electrical resistance of the ground • seismic dilatancy model • seismic gaps
Can Earthquakes be Predicted? Earthquake Prediction Programs • include laboratory and field studies of rocks before, during, and after earthquakes • monitor activity along major faults • produce risk assessments
