It is not my fault
What is a fault?
The crack in the earth's crust where stress is suddenly released causing an earthquake.

Before a volcano erupts you may experience what if you live near by.
Earthquakes
At this type of fault pieces of Earth's crust scrape past each other.
Which seismic wave cannot travel through the outer core?
The S wave
This instrument constantly records ground movement in the earth.
What is a seismograph?
A volcano found in the middle of a tectonic plates had to have been formed by a
hot spot
Water under the Earth heated up by magma then sprays out quickly is called a
Geyser
Name this fault. (slide 3)
What is a Normal Fault?
What is a Tsunami?
A wall of water created when an earthquake, usually a destructive margin, causes displacement of the ocean.
Earthquakes most often at what type of plate boundary?
Transform Plate Boundaries
What are the two type of plate boundaries that typically create volcanoes?
convergent and divergent
This type of volcano is made only from thin runny lava building up forming a dome shape.
Shield volcano
Draw a picture of a reverse fault. Label the hanging wall and footwall correctly.
Look at the notes to see the answer.
P-waves
Name at least three ways to prepare your house for an earthquake.
Extra supports, Anchor your home to the ground, mount heavy object securely to the wall etc.
What is the name of the volcano in Washington that erupted in 1980?
Mt. St. Helen
This type of volcano is tall and pointy made from layers of lava and ash stacked onto top of each other because of frequent eruptions.
Composite
The location of an earthquake on Earth's surface directly above it's focus on a fault.
What is the epicenter?
Waves travel away from this point below earth's surface causing and earthquake.
Focus
What is most likely cause of death of people during an earthquake?
Building quality/collapsing.
Ted tells Debra how he saw magma spewing out of a volcano. Debra tells him there is no way he could've seen magma coming out of a volcano because ________.
It is called LAVA once it leaves the volcano's chamber and vents.
This town was buried in 5 meters of pumice and ash after Mt. Vesuvius erupted in AD 79.
Pompeii
When examining a fault you must look at the motion of these two parts of a fault.
Hanging Wall and Footwall.
Seismograms show us what? Be specific. You can draw and label a seismogram if you would like.
The arrival and size of P waves, S waves, and Surface waves.
What does magnitude measure?
A measure of the earthquake's energy by recording ground shaking.
Billy is researching the Hawaii islands. He notices that there are a lot of islands in a row. In his report Billy writes, "a hots spot createded new islandz as it moved around under the pacific tictonic plate eruptin and releasing lava to build ub into islandz". The teacher gives him a bad grade. What was wrong with Billy's report?
First, Billy needs to work on his spelling. Second, Billy wrote that a hot spot moves. A HOT SPOT DOES NOT MOVE! The tectonic plates moves over top of a stationary hot spot.
This specific land form found at a convergent boundary creates volcanoes.
Subduction Zone
The epicenter of this earthquake is closest to what US city?
Albuquerque
When measuring earthquakes near the San Andres fault in California is there a way that seismologists can predict exactly when the next one will occur?
No, they can only make a guess of a span of about 30 years.
What is the name of the man who created the earthquake scale that measures magnitude by using ground shaking, seismograms, and the amount of damage.
Which of the following of the islands show in the picture is the oldest AND which is the youngest?
Oldest E, Youngest A
When a volcano erupts, becomes dormant and the crater collapses it now leaves a huge dent in the Earth called a what.
Caldera
The epicenter of this earthquake is located in what US State?
Oregon
What would one experience if you were at the epicenter of a 2.0 magnitude earthquakes?
Nothing. This size quake can only be detected on a seismograph.
Name a country in South America that experiences a lot of Earthquakes.
Peru, Chile, Ecuador
This is the name of the underwater sea mount that will eventually be the next island in the Hawaiian island chain in about 10,000 years.
Loihi
Before a volcano erupts you may smell a chemical gas in the air that often smells like rotten eggs. This gas is called.
Sulfur Dioxide
