Hazards and disasters in the geological and geomorphological record: a key to understanding past and future hazards and disasters

Abstract

Hazards and disasters have occurred throughout Earth's History and thus the geological record is an important resource for understanding future hazards and disasters. The Earth Science Group (ESG) of the Consortium of European Taxonomic Facilities (CETAF) carried out a “Hazard and Disaster Event Survey” to identify Earth Science collections in European museums that represent hazards and disasters throughout the geological record, and recent times. The aim is to use the collections within the survey as an educational and research resource that promotes the importance of museum collections for understanding past and future hazard and disaster events. The survey pinpointed a wide variety of hazards (e.g. earthquakes, volcanism, floods, impact events, etc.), representing a vast time span in Earth’s history (Proterozoic to Holocene), that are documented in the collections of the participating museums. Each hazard and disaster event has been described in terms of how they are preserved (e.g. fossil record or rock record), spatial scale, impact on life, and geological age. Here we showcase seven examples in detail which include well-known and less-known events from the survey that have contributed to our understanding of hazard and disaster processes and their impact on life. Also we present general conclusions and lessons learnt from the “Hazard and Disaster Event Survey”.
