Chapter 7 Section 3 Earthquakes And Society Flashcards
What is the relationship between the strength of earthquakes and the frequency with which they happen?
Strong earthquakes are less frequent and minor earthquakes are more frequent.
What is earthquake hazard?
Earthquake hazard is a measurement of how likely an area is to have damaging earthquakes in the future.
What is the gap hypothesis?
The gap hypothesis states that sections of active faults that I’ve had relatively few recent earthquakes are more likely to be the sites of strong earthquakes in the future.
What is a seismic gap?
seismic gap is an area along a fault where relatively few earthquakes have occurred recently, but were strong earthquakes have occurred in the past
What is retrofitting?
The process of making older structures more resistant to earthquakes.
How does building construction related to the damage that earthquakes can cause?
Architects and engineers can use the newest technology to design and construct buildings become better withstand earthquakes.
What are 5 types of earthquake resistant building technology?
A mass damper, the active tendon system, bass isolators, steel cross braces, and flexible pipes
How do earthquakes change human habitats?
Water lines, power lines, gas lines, roadways may be damaged during an earthquake. buildings may be damaged or collapse
What is a tsunami?
