Santiaguito, Guatemala 
Heavy rains following eruptions can trigger
mudslides known as lahars. These have significant
erosive capacity, increasing the sediment load
in the lahar. 
When this material is added to river
systems it can result in flooding.

Interacting Natural Hazards
Research / Policy / Consulting / Education 

About Us: Preparing for and responding to natural hazards could be improved by integrating information on natural hazard interactions and cascading effects, such as those described in the example from Santiaguito in Guatemala (left). These interactions are commonplace around the world but often not included in disaster management and risk reduction strategies. Our work aims to understand more about these processes and promote 'multi-hazard' approaches that consider and include them.

**2nd 'Dynamics and Impact of Interacting Natural Hazards' Workshop** 
We are exploring the possibility of organising a second workshop (see here for details of our first workshop in February 2013). You can help our planning by completing this short form to register your interest in attending.

Interacting Hazards Research
What are hazard interactions and why is it important to study them? 

In this article we attempt to present some working definitions, examples and further information about this area of work.

About Us
The team are drawn from different backgrounds and institutions around the UK.
