Geohazard notes

In response to the work of the Natural Hazards Partnership, the BGS has prepared a number of Geohazard notes to provide relevant summary information for some of the geohazards that could affect the UK.

The Geohazard notes provide information on how and why the hazard occurs, how it is measured, locations susceptible to the hazard and possible worst case scenarios.

The notes also give details on how the BGS and collaborating organisations respond to such hazards.
