Description:
Abstract Rapid estimates of source parameters are needed for reasons of civil
protection in regions where destructive events often occur. This information can
prevent further damage and casualties. A relation between the first seconds of a P-
wave onset and the local magnitude ML of the earthquake has been developed for
the Italy region following results obtained in Japan and Southern California. The
proposed dominant period estimate has been used in the present work and it gives
reliable results from which to evaluate the size of the earthquake. The data set we
evaluated consists of about 20,000 earthquakes that occurred in Italy and were well
recorded by the stations of the MedNet Network. The proposed relationship will be
one basis for developing and implementing an earthquake early warning system in
Italy capable of delivering a rapid alert only a few seconds after the occurrence of a
potentially destructive earthquake in the area. Recent extensive improvements of the
Italian National Seismic Network, together with this new technique, will make pos-
sible the release of a robust magnitude estimate no later than 10 sec after the occur-
rence of the earthquake. However, no data are available for earthquakes with mag-
nitudes ML
