This wave behaviour can also be used on a smaller scale by recording waves generated by explosions or ground vibrators in the search for oil and gas. The P wave can move through solid rock and fluids, like water or the liquid layers of the earth. (slide 12) Rayleigh waves are another type of surface wave. In this lesson, we discussed four types of seismic waves: P-waves, S-waves, Rayleigh waves and Love waves. endobj S-waves, or secondary waves travel more slowly than P waves. �N(�5�*���դB��ys��A�`$aI���h{B_5y,)��N�@+ՠϔ"���RLK�Į,t�-�V��t9jQ�Xb�*�Ԫ�$�0Yur��$��th����.��DI���/�$R�'�֣��$:���y>ٯn?޸� �F��-���g;��6#2ru]�K(L���禹�i�B������Äd�,��*������b0+��~?�=�H}'���N��/��iI�nh��p����,�9��n���c��[$v�)����J\We�W��{C�a������s�b��l���m��#�|D�ö^猰�j�d��yA����v��Ǧ��2��ji�#7|�x7�H*��N���s���s��A�v"��j��&\mw�[�!�M2*6����L�E0�������h)�:2�;0���d7�$sGe���o��s�2�0߬��]�TP&c"����� �xٲ��{wmEv�2_�I��p��_p�m�iL�>m����&L����l��C�����t0;U Red - seismic waves travel more slowly than normal . Earthquake waves, more commonly known as seismic waves, are vibrations generated by an earthquake and propagated within Earth or along its surface. 2. Earthquakes generate four principal types of elastic waves; two, known as body waves, travel within the Earth, whereas the other two, called surface Body waves - arrive before the surface waves emitted by an earthquake.
