| Summary: | By means of a statistica! metliod of Caloi-Peronaci, the<br />author determines the space-time coordinates of the deep earthquake which<br />took place in the lower Tirrenian sea on Jan. 3, 1960.<br />Through a series of attemps performed by making the recording times<br />of the P's intervene in divers station groupings (intermediate, intermediate<br />and far, intermediate and near), emphasins is given to the utility of the<br />data of near stations with regard to a better determination of depth and<br />origin time.<br />The most probable equations of tlie travel-time curves of the P waves<br />are worked out, valid up to distances of 30&deg;. The equations thus obtained<br />make evident anticipations of the order of 2S in the stations of Messina and<br />Reggio C. with regard to the times foreseen according to tlie Jeffreys and Bullen<br />tables. The travel-time curves obtained for the group of scandinavian<br />stations ( 18&deg;,6 ^ A &lt; 30&deg;) shows anticipations from 6 about (Goteborg) to zero. |
