Question

The graphical record of an earthquake​

Answer 1

Answer:

The graphical output from a seismograph is called a seismogram. Figure 12.10 (right) shows how a seismograph works. The instrument consists of a frame or housing that is firmly anchored to the ground.A seismograph, or seismometer, is an instrument used to detect and record earthquakes. Generally, it consists of a mass attached to a fixed base. During an earthquake, the base moves and the mass does not. The motion of the base with respect to the mass is commonly transformed into an electrical voltage.

Answer 2

The Correct solution is Seismogram

• Earthquakes unleash energy in the form of seismic waves as the Earth trembles.
• The primary earthquake measuring instrument is a seismograph.
• The seismograph records the ground motion induced by seismic waves as a digital graphic.
• A seismogram is a name for digital recording.
• The power and duration of the earthquake's waves are detected and measured by a global network of seismographs.
• The seismograph generates a digital graphic mapping of the event's ground motion.
• The instrument is made up of a sturdy frame or enclosure that is affixed to the ground.
• On a spring, a mass is suspended from the housing and can move freely.
• When the ground trembles, the house trembles as well, but the mass remains constant.
• A seismogram is created when a pen attached to the mass goes up and down on a revolving drum of paper, forming a wavy line.
• The Moment Magnitude Scale is now used to determine the magnitude of earthquakes (MMS).
• The rocking movement along the fault is measured by MMS. Broader earthquakes, which can last minutes, affect a much larger region, and inflict more damage, are properly measured.
• The local Richter magnitude (ML), body-wave magnitude (Mb), and surface wave magnitude can all be measured with the Moment Magnitude (Ms).
