Question

from the seismogram, the distance to the epicenter can be determined by measuring

Answer 1

Answer:

The distance between the beginning of the first P wave and the first S wave tells you how many seconds the waves are apart. This number will be used to tell you how far your seismograph is from the epicenter of the earthquake. Measure the distance between the first P wave and the first S wave.

Answer 2

• A seismogram is a graph drawn by a seismograph.
• A seismogram is an instrument used to measure the intensity of earthquake.
• Seismograms record motions in three cartesian axes (x, y, and z), with the z axis perpendicular to the Earth's surface and the x- and y- axes both parallel to the surface.
• The records measured in a seismogram may result from an earthquake or from some other source, such as an explosion.
• Seismograms can record little waves, called microseisms.

• The time between the two waves can be measured by the distance between the beginning of the first P wave and the first S wave.
• This can in turn used to measure the distance between the epicenter of the earthquake and the seismogram.
• In this way from the seismogram, the distance to the epicenter can be determined.
