4 cards from this section. Quick, good the night before a test.
What is the definition of the hypocentre?
Think about where the earthquake starts.
What are the two types of primary seismic waves discussed?
Remember, one wave travels through solids and fluids.
What is the point where an earthquake begins called?
It's the deep source of the shock.
True or False: The epicentre is directly below the hypocentre.
Think about what happens above versus below ground.
Given an earthquake with multiple seismic stations, if the P-wave arrives first at 3 stations with time differences of 6 seconds between them, calculate the approximate distance to the hypocentre from each station.
Use the distance formula and remember the time difference represents how far behind each station is.
Analyze how the depth of a hypocentre can influence building design in an earthquake-prone area, focusing on how shallow vs. deep earthquakes require different materials or structures.
Think about how shaking affects different structures and what material responses might be necessary.
