Lesson 42-5     Recording an earthquake

it would be up anddown, to and fro and from side to side. Instruments have been devised and canbe so placed that all three elements can be recorded in different graphs.

When theinstrument is situated at more than 700 miles from the earthquake centre, thegraphic record shows three waves arriving one after the other at shortintervals. The first records the arrival of longitudinal vibrations. The secondmarks the arrival of transverse vibrations which travel more slowly and arriveseveral minutes after the first. These two have travelled through the earth. Itwas from the study of these that so much was learnt about the interior of theearth. The third, or main wave, is the slowest and has travelled round theearth through the surface rocks.
