Volcanic Hazard Maps Improve Disaster Preparedness in Colombia

On January 14, 1993, the Galeras Volcano unexpectedly erupted, killing six scientists and three tourists on an expedition to its summit. Since then, the volcano has errupted again in 2005 and 2008. Volcanic hazard maps used with remote sensing data and digital elevation models are effective in helping people responsible for the public welfare of communities exposed to volcanic risk explain volcanic hazardous situations.
