If you live in an area earthquakes occur frequently, it is a good idea to place heavy household objects here.
What is close to the ground/on a low shelf/in a low cupboard?
100
This type of volcano is formed by a combination of granitic magma and low gas pressure within the magma chamber.
What is a lava dome?
100
An instrument used to measure the magnitude of an earthquake.
What is a seismograph?
100
This giant wave is an earthquake-related risk for people who live near the ocean.
What is a tsunami?
100
This is the LEAST viscous (thinnest) type of magma.
What is basaltic magma?
200
To prevent damage during an earthquake, these wall-hanging objects should be hung on closed hooks.
What are mirrors and/or pictures?
200
This type of volcano is formed by many quiet eruptions of basaltic magma. Mt. Kilauea in Hawaii is an example of this volcano type.
What is a shield volcano?
200
An earthquake can occur when rocks are streched or bent past this limit.
What is elastic limit?
200
If you are going to live in a tsunami hazard zone, it is a good idea to make sure that your house is built on this location.
What is a hill/high ground?
200
This is the MOST viscous (thickest) type of magma
What is granitic magma?
300
People who live in a tsunami hazard zone should pay close attention to these in order to receive warnings about incoming tsunamis.
What is the news OR the national weather service?
300
This type of volcano is formed by alternating layers of lava and tephra. Mt. Popocatepetl in Mexico is an example of this type of volcano.
What is a stratovolcano/composite volcano?
300
The point beneath the Earth's surface where an earthquake begins.
What is the focus?
300
A historian found evidence of an "orphan" tsunami that hit the Japanese coast 300 years ago in these written accounts.
What are Japanese tsunami records?
300
These two factors determine whether a volcanic eruption will be quiet or explosive (Miss W did demos of these with a pop bottle and peanut butter).
What are magma viscosity and gas pressure?
400
Installing strong latches on the doors of these can prevent objects from falling out during a strong earthquake.
What are refrigerators and/or cabinets and/or cupboards?
400
A large volcanic crater typically formed by a major eruption leading to the collapse of the mouth of the volcano. Crater Lake is an example of this type of volcanic crater.
What is a caldera?
400
The point on the Earth's surface that is directly above an earthquake's focus.
What is the epicenter?
400
An expert looked at tree rings in this mysterious location to determine if a tsunami could have drowned trees here 300 years ago.
What is the ghost forest?
400
This material forms when lava is thrown into the air and solidifies before it hits the ground. Eruptions of this material often form cinder cones.
What is tephra?
500
Buildings made out of these are the most dangerous during an earthquake because they are so brittle.
What are bricks?
500
DIAGRAM CHALLENGE: this is a diagram of volcano formation at a subduction zone (convergent plate boundary)
What is this diagram?
500
DIAGRAM CHALLENGE: This is a diagram of the focus and epicenter of an earthquake.
What is this diagram?
500
A Washington geologist found evidence of burried spruce forest here, which suggests that a large earthquake and tsunami struck Oregon and Washington 300 years ago.
What is a salt marsh?
500
Eruptions caused by this thin type of magma are quiet, and usually form shield volcanoes.
