Quake: 100 after-shocks during the night, strongest 4.5

(ANSA) - Rome, August 25 - There were some 100 after-shocks overnight in the areas hit by a 6.0-magnitude earthquake that killed at least 247 people Wednesday, the strongest measuring 4.5 at 05.17 near Rieti, geologists said Thursday.
    The said it was normal to have such after-shocks.
    "The after-shocks are continuing in a way that is consistent with theoretical models," they said. They also said that quakes of 6.0 magnitude happen on average every 15 years in Italy, a fact that should prompt further risk prevention.
