fast wave; 4-7km per second
study of earthquakes
result of rock movement along fault
shallow-focus earthquakes; normal faults parallel to the rift valley
opening of tiny cracks changes the rock's porosity resulting to a rise or fall in water level
seismic sea waves due to the sudden movement of the sea floor
small earthquakes that follow the main shock
trembling or shaking of the ground caused by sudden release of energy stored in the rocks beneath the Earth's surface
first to arrive at a recording station
point within the Earth where seismic waves originate
amount of energy released at the earthquake's focus - magnitude; measuring height (amplitude) of wiggles in a seismogram
measure of an earthquake's effect on people and building; intensity
first alerted scientists to the phenomenon of subduction
0-70 km deep; divergent and transform plate boundary, some convergent
can be triggered by the shaking of ground
small tremors caused by small cracks that may open within a rock
seismometer with a recording device that produces a permanent record of earth's motion
Collision of two continents; broad zones of shallow earthquakes on a complex system of faults
rock vibrations caused by release of elastic energy
geologically active regions
maximum depth of focus
each magnitude increase in a Richter scale corresponds to ___ increase in amt of energy released
zones of shallow- and deep-focus earthquakes
rock vibrates perpendicular to the direction of wave propagation
slower, transverse wave; 2-5km per second
compressional wave
Rock vibrates parallel to the direction of wave propagation
70-300 km; convergent
a paper record of Earth vibration
discovered the actual mechanism of earthquake
trembling and shaking of land that can cause buildings to vibrate
shallow earthquakes; strike-slip motion on faults parallel to the boundary
a serious problem after an earthquake because of broken gas and water mains and fallen electric wires
changes in magnetism and electrical resistivity of the rock
300-700 km; convergent
subduction of the ocean floor
the point on the Earth's surface directly above the focus
travel on the Earth's surface away from the epicenter, slowest waves, cause more damage
longitudinal wave
travel through the Earth's interior, spreading ouward from the focus in all directions
the difference between two consecutive numbers in a Richter scale means an increase ___ in the amplitude of the Earth's vibrations
plots seismic wave arrival time against distance
