This map illustrates an overview of potential tsunamis inundated areas according to wave high categories of 2,5m; 5m; 7,5m and 10m covering reported affected districts by OCHA as of 25 December 2018 in Lampung Province, Island of Sumatra, Indonesia.
Preliminary affected building estimates reported in the table are only based on available OSM building footprints and LAPANs Tsunami inundation model, itself derived from a National Digital Elevation Model (DEM) that does not take into account the thrust of the tsunami's waves caused by the underwater landslide triggered by the volcanic eruptions of Anak Krakatau on 22 December 2018.
Therefore, statistics provided are model derived and not based on (post tsunami) satellite derived analysis. Both tsunamis model derived inundation extents and building statistics have not yet been validated in the field.
