A modern seismograph can help scientists detect earthquakes and measure several aspects of the event: The time at which the earthquake occurred. The epicenter, which is the location on the surface of the earth below which the earthquake occurred. The depth below the earth's surface at which the earthquake_occurred.
How high is the Richter scale? Numbers for the Richter scale range from 0 to 9, though no real upper limit exists. An earthquake whose magnitude is greaterthan 4.5 on this scale can cause damage to buildings and other structures; severe earthquakes have magnitudes greaterthan 7.
What units are used in the Richter scale? Seismologists now measure earthquakes by the seismic moment (M0), which has the units of energy: N-m (Newton-meter) or dyne-centimeter. The seismic moment is also converted to a logarithmic moment-magnitude scale that was designed to match the-magnitude scale developed by Charles Richter.
Can a seismograph predict earthquakes? Seismograms contain information that can be used to determine how strong an earthquake was, how long it lasted, and how far away it was. Modern seismometers record groundmotions using electronic motion detectors. The data are then kept digitally on a computer. These seismograms show the arrival of P-waves and S-waves.
What is the difference between seismograph and Richter Scale? A seismograph is a tool which measures movement. The Richter scale describes the intensity of anearthquake. So there is a relationship - the seismographic readings will display the intensity at a certain location. The 'Richter' number is a measure of the total energy released by the earthquake.
