Earthquakes Introduction to Earthquakes

Aim, Learning Target and Agenda  AIM:  How do I explain and illustrate what happens during an earthquake?  Learning Target:  I can use explain and illustrate what happens during an earthquake  Agenda  Catalyst  Intro to C-squared  Earthquake footage  Earthquake vocab  Practice!

Do Now  You have 4 minutes!  What is the name of the plate boundary where earthquakes usually occur?  Divergentc. Convergent  Subductingd. Transverse  Arrows in the block diagram (at right) show the relative movement along a tectonic plate boundary. Between which two tectonic plates could this type of plate boundary exist?

Earthquake footage  From a quake in California in 1989  t/environment-natural-disasters/earthquakes/earthquake- montage.html

San Andreas Fault

Earthquake  A natural, rapid shaking of the lithosphere caused when rocks are displaced due to the release of energy stored in rocks; most caused by rapid movements along faults, but also associated with other events, such as volcanic eruptions.  Earthquakes occur at TRANSFORM boundaries

Some vocab! Fault – a crack in a landmass where there has been displacement, shifting, or movement of land on both sides  Focus - the place where an earthquake originates  Epicenter- the place on Earth’s surface lying directly above the focus, or the origin of an earthquake

Energy builds up and is released in the form of...  Seismic waves – the energy waves given off by an earthquake. Also called earthquake waves.

Two types of seismic waves P wavesS waves P for primary (meaning 1 st ) S for secondary (meaning 2 nd ) FasterSlower Travels throiugh solid, liquids and gas Travels through solids only

We can figure out information about the epicenter based on seismograms.

Complete Practice Problems  What is the focus?  What is the epicenter?  Draw a picture that shows the focus, epicenter, and movement of the waves when an earthquake occurs. (Hint: draw a side view of the earth)  How are P- and S-waves different?
