Summary

VOGRIPA is the Volcanic Global Risk Identification and Analysis Project, the objectives of which are are to create a global database of volcanic activity, hazards and vulnerability information that can be analysed to identify locations at high risk from volcanism, gaps in knowledge about hazards and risk. It will allow scientists and disaster managers at specific locations to analyse risk within a global context of systematic information.

So far an online database of large magnitude explosive eruptions reaching back to the Quaternary has been constructed, which can be used to evaluate the magnitude-frequency relationship of such events, and also an assessment of how the quality of records affect the results. Future expansion will include specific databases on hazards such as lahars, pyroclastic flows and tephra fall as well as the inclusion of a vulnerability component for converting hazard to risk.

VOGRIPA is closely linked with the Smithsonian Institution's Global Volcanism Program database and is part of the newly launched Global Volcano Model project being run in conjunction with the British Geological Survey along with numerous international partners.
