This time interval, pP-P (pP minus P), is used to compute depth-of-focus tables. The following shows the steps used: Get three seismograms. By studying seismograms, scientists learn a lot about Earth's internal structure, like how fast the waves are moving and what type of material the waves are passing through. During an earthquake, ground-shaking seismic waves radiate outward from the quake source, called the epicenter. Today computers are being used to analyze seismographic data. Just as this impact sets waves in motion on a quiet pond, so an earthquake generates seismic waves that radiate out through the Earth. Scientists have come up with a number of ways to figure out the location of an epicenter. We encourage teachers and other education stakeholders to email their feedback, comments . A seismometer detects seismic waves below the instrument and records them as a series of zig-zags. These three distances are then used to triangulate the epicenter. The main importance in determining the epicentre is so that the fault that ruptured causing the earthquake can be identified. Seismographs can detect quakes that are too small for humans to feel. People who study seismology examine earthquakes and how waves of energy move through the Earth's layers.. Studying seismic waves are very important because it can increase the awareness and knowledge of people regarding the movement of the Earth's surface, in connection to this, people can easily be alert during an incoming calamity that is caused by Earthquakes.
