The earthquake that occurred in the region on 13 May 1995 was 6.6 on theRichter magnitude scale, but it caused only material damage. The worst hit area was the county of Ventzia. There were two foreshocks of lesser intensity that preceded the main earthquake by a few minutes and warned people. These warnings sent the population out of their houses. When the main earthquake came, it destroyed nearly all the houses in several villages of the Ventzia County – the houses collapsed to the ground – but all the inhabitants were outside.
