---|---|---|---|---|
What is this number XII.
how powerful is a total destruction earthquake on the modified mercalli scale.
|
What is magnitude
The measure of an earthquakes strength
|
What are earthquakes
a natural disaster caused by tectonic plates crashing together
|
what kind of wave of energy that travels through the earth
seismic wave
|
what are flexible pipes
pipes preventing water and gas lines from breaking
|
What is this number I
how power is a not felt earthquake on the modified mercalli scale
|
What is a Richter scale
scale to measure magnitude
|
What are tectonic plates
Plates that make earthquakes
|
what kind of earthquake starts at the depth of 700km
convergent boundaries
|
what are cross braces
balances that pushes and pulls at the side of the building
|
What is this number II
how powerful is a earthquake if its only felt by a few people on the modified mercalli scale
|
When is water saturated soil shaken by seismic waves
When grains that make up the sediment lose contact one another
|
What is a mercalli scale
a chart used to describe earthquakes intensity
|
what kind of earthquake starts at the depth of 50km
transform boundaries
|
what is a mass damper
a weight placed in the roof of buildings
|
What is this number III
how powerful is a earthquake if it is mostly felt by most people inside modified scale
|
What four factors affect intensity
brick,concrete,wood,and steel
|
Why do earthquakes happen
tectonic plates move
|
what kind of earthquake starts at the depth of 20km
divergent boundaries
|
what is the active tendon system
something that works like the mass damper
|
What is this number VI
How powerful is an earthquake if the earthquake can make heavy objects move on the modified scale
|
What is intensity
The amount of damage caused by an earthquake
|
What is the sudden return of elastically deformed rock
elastic rebound
|

seismic wave
|
