Zones where earthquakes occur
The zones where two plates meet each other.
What are plate boundaries?
A type of hazard that can produce pyroclastic flows.
What is an explosive volcanic eruption?
A large ocean wave or series of waves caused by an undersea earthquake, eruption, explosion or landslide.
What is a tsunami?
The device containing a seismometer that is used to measure and record the energy of shockwaves produced by movements of Earth's crust.
What is a seismograph?
An event or process that has the potential to cause harm.
What is a hazard?
The type of earthquake you would expect at divergent boundaries.
What is a shallow focus earthquake?
A type of hazard that produces runny lava and gas emissions.
What is an effusive volcanic eruption?
The technical term for the shaking of the Earth's crust during an earthquake.
What is ground motion?
The way in which energy from earthquakes travels through the Earth's crust.
What is a seismic wave?
An event or process that has caused large-scale harm such as loss of life or massive damage to ecosystems or infrastructure.
What is a disaster?
The type of boundary that produces deep focus earthquakes.
What is a convergent boundary?
The type of boundary associated with effusive volcanic eruptions.
What is a divergent boundary?
The fastest type of wave from an earthquake, a longitudinal wave that moves the Earth's crust back and forth in the same direction as it is travelling.
What is a primary wave?
The second fastest type of wave caused by an earthquake, which only travels through the solid parts of the Earth.
What is a secondary wave?
A type of hazard that involves the Earth's crust.
What is a geological hazard?
The characteristic of an earthquake that is to do with how deep the origin point is.
What is earthquake focus depth?
The type of plate boundary associated with volcanic mountain chains on land and explosive eruptions.
What is an ocean-continent convergent boundary?
The point in the Earth's crust where two plates move along a fault to cause an earthquake.
The characteristic of an earthquake that describes how big it is and how much energy it released.
What is the magnitude of an earthquake?
What is a biological disaster?
The process that generates the friction which causes deep focus earthquakes to occur.
What is subduction?
What is the silica content of magma?
The point on the Earth's surface that typically receives the most energy and experiences the most damage from an earthquake.
What is the epicentre of an earthquake?
The slowest but often most destructive type of wave caused by an earthquake, which makes the crust move in a rolling motion.
What is a surface wave?
The type of natural disaster that Australia is most likely to experience.
What is a meteorological disaster?
