FORECASTING

Eruptions are often preceded by a number of indicators that are detectable from space, including subtle increases in surface temperature. 

DETECTING

The first indications of eruption are often identified in satellite data by strong thermal anomalies and/or the presence of ash and gas in the atmosphere, the recognition of which can be automated for rapid eruption detection. 

TRACKING

Once an eruption is in progress, space-based imagery can track activity over time, providing information on the emplacement of volcanic deposits, the presence and character of ash plumes, and potential changes in the character of the eruption.

QUANTIFYING

Quantifying and thus characterizing eruptive products is then required for hazard assessment.

NOWCASTING

Finally, short-term prediction of the evolution of volcanic phenomena allows to accelerate the response to volcanic hazardous events.
