Chapter 2

 Seismic waves cause the seismograph’s drum to vibrate. But the suspended weight with the pen attached moves very little. Therefore, the pen stays in place and records the drum’s vibrations.

 The zig-zag pattern of lines created by a seismograph is known as a seismogram.  The height of the jagged lines drawn on the seismograph’s drum is greater for a more severe earthquake or for an earthquake close to the seismograph.

 To monitor faults, geologists have developed instruments to measure changes in elevation, tilting of land surfaces and ground movements along faults.  These instruments include:  Tiltmeters  Creep Meters  Laser-ranging Devices  Satellites

 A tiltmeter measures tilting or raising of the ground.  A creep meter uses a wire stretched across a fault to measure horizontal movements of the ground.

 A laser-ranging device uses a large laser beam to detect horizontal fault movements. The device times a laser beam as it travels to a reflector and back  Scientists can monitor changes in elevation as well as horizontal movements along faults using a network of Earth-orbiting satellites called GPS.

 Seismographs and fault-monitoring devices provide data used to map faults and detect changes along faults. Geologists are also trying to use these data to develop a method of predicting earthquakes.
