Study Notes

Earthquakes: Definition, Energy Release, and Impact on Structures

Earthquakes are the rapid release of energy along faults caused by large-scale motions beneath the crust.
The energy is released in the form of waves that can be studied using the same physics behind studying water waves.
The buildup of energy is caused by tectonics and the longer it goes, the bigger the earthquake will be.
The hypocenter or focus is where the actual break in the rock occurs, and the epicenter is the point directly above the hypocenter on Earth's surface.
The longer an area is overdue for an earthquake, the larger the earthquake will be.
The Cascadia megathrust, located between the Juan de Fuca and North American plates, is overdue for an earthquake.
The energy released during an earthquake travels down the fault line and magnifies in areas built on unconsolidated sediment.
Mexico City has substantial damage in earthquakes because it is built on lake beds and poorly built structures.
Japan builds earthquake-proof structures and retrofit buildings to minimize damage during an earthquake.
The most deadly thing in an earthquake is a poorly built structure.
The impact of an earthquake can cause water to come shooting out in a process called liquefaction.
Earthquake waves are named primary waves, secondary waves, and surface waves.

Earthquakes and Seismology

Covering your head during an earthquake by going under a table can slow down the impact of falling debris.
The best thing to do during an earthquake is to get outside, and in Japan, they have earthquake warning apps that send immediate messages to get outside.
Poorly built buildings are one of the biggest killers during earthquakes.
Doorways are often framed more securely and can provide some protection during earthquakes.
Nuclear bombs can cause earthquakes, and it's safer to cover yourself under something than to pile on top of yourself.
Elastic rebound is an analogy for earthquakes, where stress builds up and eventually causes the earthquake.
Henry Reid was the first person to identify a fault line during the San Francisco earthquake, before the idea of plate tectonics.
Earthquakes are often preceded by foreshocks and followed by aftershocks.
Different types of tectonic forces build up stress and strain in rocks, including convergent, transform, and divergent boundaries.
Convergent boundaries produce the largest earthquakes and volcanoes, while divergent boundaries produce small shallow earthquakes.
Mega thrust faults are the sites of the earth's largest earthquakes, and they can cause tsunamis.
Seismology is the study of earthquake waves, and seismographs are instruments that record them. The Richter scale measures the maximum amplitude of the wave to calculate the magnitude of the earthquake.Classroom Q&A Session on Earthquakes
The speaker is conducting a Q&A session on earthquakes.
Some people are already feeding during the session.
The speaker tells them to leave and start the session.
The speaker plans to answer five questions during the session.
The first question is about the fault and the answer is square.
The second question is about the cause of convection currents.
The speaker plans to skip the remaining questions and move to the podium.
The speaker forgot to discuss a topic and plans to cover it in the next session.
The speaker asks if the students completed the homework due yesterday.
Triangulation is explained as a method with three sides.
The Richter scale is no longer used to record earthquake magnitudes.
The speaker apologizes for holding the students for so long and tries to wrap up the session.
