| Modèle de Herrin 1968: Cette table est calculée sur un modèle de croûte terrestre formé de deux couches. La première a 15 km d'épaisseur et une vitesse de propagation de l'onde P de 6.0 km/s (discontinuité de Conrad), la deuxième de 15 à 40 km à une vitesse de l'onde P de 6.75 km/s (discontinuité de Mohrovicic). La vitesse de l'onde P en dessous de la discontinuité de Mohrovicic, 40 km de profondeur, est de 8.0 km/s. La vitesse de l'onde S est déduite de celle de l'onde P dans un rapport de racine de 3. | ||||||||||
| La distance épicentrale est mesurée en degré, les temps et différence de temps sont mesurés en secondes. | ||||||||||
| Les ondes Pg et Sg sont les ondes directes. | ||||||||||
| Les ondes PcP et ScS sont les ondes réfléchies sur la discontinuité de Conrad. | ||||||||||
| Les ondes P*( ou Pb) et S*( ou Sb) sont les ondes réfractées sur la discontinuité de Conrad. | ||||||||||
| Les ondes PmP et SmS sont les ondes réfléchies sur la discontinuité de Mohrovicic. | ||||||||||
| Les ondes Pn et Sn sont les ondes réfractées sur la discontinuité de Mohrovicic. | ||||||||||
