300
Where an earthquake begins
What is the hypocenter
300
How do earthquakes cause tsunamis?
by causing the seafloor to move or by triggering a landslide
300
the volcanic rock and lava blasted into the area or carried by gases
What is tephra
300
the stability of a slope can be assessed by determining the relationship between
the driving and resisting force

What is Pangaea; Laurasia, Gondwana
500
other hazards earthquakes are linked to
What are fires, liquefaction, landslides
500
when a tsunami has been detected and is spreading across an ocean towards an area
What is a tsunami warning
500
these volcanoes are formed by the build up of tephra
What are cinder cone volcanoes
500
How can landslides be prevented?
drainage control, grading, slope supports
