QuestionAnswer
whats seismology? branch of earth science devoted to study earthquakes.
whats deformation ? is the change in the shape of rock in response to stress.
whats elastic rebound? the sudden return of elastically deformed rock to its undeformed shape.
what major fault type is related to transform? strike - slip fault
what major fault type is related to convergent? reverse fault
what major fault type is related to divergent? normal fault
what are seismic waves? a wave of energy that travels through the earth away from an earthquake in all directions.
what are the 3 types of seismic waves? s,p and surface
What is the difference between P and S waves? The s waves move side to side the p waves move back and forth.
whats a movement of a s wave? a seismic wave that causes particles of a rock to move in a side -to -side direction.
what the movement of a p wave? a seismic waves that cause particles of a rock to move back and forth direction
what the movement of a suface wave? move along earth’s surface and produce motion mostky in the upper few kilometers of earth’s
whats a seismograph? - an instrument that records vibrations in the ground and strength of an earthquake
what is a seismogram? a tracing of earthquake motion that is created by a seismograph
what is a focus? the point along a fault at which the first motion of an earthquake occurs
whats epicenter? the point along a fault at which the first motion of an earthquake occurs
How do seismologists forecast earthquakes? They forecast them by 2 S-P time method- The s-p method is used to find the epicenter.
what are the scales? The richter scale and the Modified Mercalli Intensity Scale.
What is earthquake hazard? It is a measurement of how likely an area is to have damaging earthquakes in the future.
How does the strength of an earthquake relate to the frequency of earthquakes? strength of earthquakes is related to how it often the occur.
Explain the gap hypothesis. The gap hypothesis is based on the idea that the sections of active faults that have had relatively few earthquakes are likely to be the sites of strong earthquakes in the future.
whats mass damper? weight placed in the roof to countreact the building movement
whats cross braces? weight placed in the roof to countreact the building movement
whats the active tension system? ike mass damper only in the basement
what are bass isolators? acts as a shock absorber
what are flexible pipes? prevent waterlines and gas lines from breaking
before the earthquake what do u do? prevent waterlines and gas lines from breaking
during an earthquake what do u do? indoors- crouch under table in center room outside- lay face down away from trees, buildings and powerlines.
after an earthquake what do u do? stay calm wait for the all clear and then remove yourself from danger be prepared for after shock elf
