WOVO is an organization of and for volcano observatories of the world. Members are institutions that are engaged in volcano surveillance and, in most cases, are responsible for warning authorities and the public about hazardous volcanic unrest.
We aim to:

• stimulate communication and cooperation between observatories and institutions directly involved in volcano monitoring
• develop and maintain volcano monitoring reference materials, including a Directory of member observatories, their monitoring networks and staff
• upon request, to help a member observatory to find temporary scientific reinforcement
• refer governments, international organizations, and others seeking assistance in volcano monitoring to the appropriate member observatories.
