We present a social media crisis mapping platform for natural disasters. We take locations from gazetteer, street map and volunteered geographic information (VGI) sources for areas at risk of disaster and match them to geo-parsed real-time tweet data streams. We use statistical analysis to generate real-time crisis maps. Geo-parsing results are benchmarked against existing published work and evaluated across multi-lingual datasets. We report two case studies comparing 5-day tweet crisis maps to official post-event impact assessment from the US National Geospatial Agency (NGA) compiled from verified satellite and aerial imagery sources.
