  The current paper explored aspects of social media datasets when those were treated for disaster management (DM). The aspects were accumulated into three basic components: I. simultaneous processing of multiple social media sources. ii. Processing of multiple modalities iii.

After scraping the data were merged per modality, resulting to a dataset of 7,058 text strings, 2,949 photos and 168,150 video frames, extracted from 752 YT and Instagram videos.
