Workshop on Remote Sensing and GIS Modeling on Volcanoes

A Workshop was held by the Earth Observatory Singapore(EOS) and Volcano Disaster Assistance Program (VDAP) of the United States Geological Survey (USGS) from March 3 - 10, 2010.

Here, scientists from across Southeast Asia from Indonesia, Philippines and Papa New Guinea came to Singapore to learn about using Remote Sensing data and GIS Modeling for Volcanic Hazards. Also, the participants got first hand use of current ashfall and volcanic ash and dispersion modeling.

They learnt about the following:

- How they can use online Remote Sensing tools for thermal monitoring and ash clouds

- The use of GIS for analyzing Lahar modeling and Ashfall predictions

- Volcanic Ash Modeling with the UAF-GI Puff model ( and the NOAA Hysplit model (

- A background into the scientific understanding of volcanic ash and sulfur dioxide detection with remote sensing data

- An introduction to ENVI for analyzing remote sensing data for thermal ground signals, ash clouds and volcanic sulfur dioxide

- Where satellite data is available online and how to access it for their volcanoes of interest

The final part of the workshop involved the participants to discuss how to use the data in their local observatories and institutes. This was an exercise to work in groups and assess the capabilities to use the data and tools shown in the workshop once they returned.
