The Volcano Early Warning System
The Volcano Early Warning System GEOWARN is designed on a scientific basis
to cover the most significant gap in current volcanic unrest monitoring procedures,
the step form green to yellow of the international "Volcano Alert Levels"
The early warning system of GEOWARN in its current form does not provide for
immediate volcanic eruption prediction (long-term) and forecast (short-term);
its central purpose is to provide early warning of reactivation in order to
permit timely installation of a costly real-time monitoring network.
When changes in the monitored parameters in space and time have been repeatedly
observed by the GEOWARN system, a decision could be made to expand its capabilities
to include real-time monitoring surveillance necessary to volcanic eruption
prediction and forecasting.
