10 Questions
What is the role of a seismograph?
To measure and record details about earthquakes
What causes earthquakes to occur?
Sudden slipping of tectonic plates along a fault
What is the location on Earth's surface where a fault can be seen?
Fault line
What is the role of foreshocks in a series of earthquakes?
They precede the mainshock in a series of earthquakes
Why are geologists unable to predict when earthquakes will occur?
Activities along fault lines are unpredictable
What is the primary difference between foreshocks and aftershocks?
Foreshocks occur before the mainshock, while aftershocks occur after the mainshock.
Why is it impossible to predict an earthquake by measuring seismic activity from a foreshock?
The initial quake could be either a foreshock or a mainshock, making it impossible to predict if another quake will happen.
Under what circumstances can an aftershock be redefined as the main quake?
If the aftershock is stronger than the mainshock, it can be redefined as the main quake.
What causes aftershocks to occur?
Aftershocks occur when the energy released from a mainshock is passed on to nearby rocks, building up pressure until it is released as seismic waves.
How long can aftershocks last after a mainshock?
Aftershocks can last anywhere from a few days up to years after a mainshock takes place.
