Each year, new lessons are learned during volcano crises around the world. VDAP works with volcano observatories to develop best practices for response, communications, and alerts. Representatives meet periodically to discuss new challenges, insights, and developments. The USGS and the Istituto Nazionale di Geofisica e Volcanologia in Italy work with VDAP and others to sponsor representatives from many countries that would otherwise lack funding to attend. VDAP also contributes to best-practices workshops at international volcano conferences, which bring together civil authorities, emergency responders, and volcanologists who work at dangerous volcanoes around the world.
