The outcome of this study is that 99% of liquefaction sites
are located 0e100 m from a water body, and 94% consist of Holocene sediments and 6% of artificial fill. In
addition, in order to present the data under a GIS environment, information in the database was exported
into Google Earth kmz format. A web interface of DALO was developed and made available at the web site
http://users.auth.gr/wgpapatha/dalo.htm where three maps are presented regarding historical liquefaction
occurrences. Photos and figures of the ground or structural failures have been uploaded as well,
mainly for the events that occurred after 1950. This GIS-based dataset can be helpful, especially to
decision makers and urban planners, as it can be used as a screening guide of liquefaction hazard for
avoiding in advance liquefaction prone areas.
