stations

The data used for creating this catalogue are those recorded by the INGV Seismometric National Network and by the regional networks of Marche, Abruzzo, Umbria and Northeastern Tuscany (see figure below).
stazioni stazioni

The P and S delays, calculated with inversion algorithm, are associated with each station. (see figures left and right, respectively)

The stations of the Seismometric National Network record the data in real time using different types of sensors (velocimeters and accelerometers) with three components and several own periods: 1, 5, 40, 120 and 240 seconds.
The stations of the regional networks used the dial_up modality (with a sensitivity of trigger different from one network to another) and were all equipped with three components velocimeters (Lennartz or Mark) with own period of 1 second.
While for the national network stations the acquisition of original data is in continue real time, for those of regional networks is in dial up modality, with a sensibility of trigger different from network to network.
