Satellite Images Capture Toxic Red Sludge in Hungary an Environmental Disaster

Satellite Images captured the environmental disaster of a contaminated waste reservoir that gave way to 24.7 million cubic feet of toxic red sludge on October 4th, 2010,  killing nine people, injuring 150, forcing home evacuations and ruined property over 15 square miles.

The red sludge devastated creeks and rivers near the spill site and entered the Danube on Thursday October 7th 2010, moving downstream toward Croatia, Serbia and Romania.

The IKONOS one-meter resolution satellite image features a portion of Hungary’s toxic sludge spill east of Ajka, Hungary in the village of Kolontar. The image was taken on October 7th, 2010 and shows a close-up of the holding pond where the red mud pollution broke through the retainer wall. On the same day the image was captured authorities reported the spill had reached the Danube River, threatening to contaminate the waterway’s ecosystem. The image was collected by the IKONOS Satellite from 423 miles in space as it moved from north to south over Hungary at a speed of 4.2 miles per second.

Environmental Disaster Analysis and Monitoring Using Satellite Imagery

Satellite Imagery incorporated with Geographic Information Systems (GIS), can give emergency officials a wealth of information for prevention, analysis, assessment and monitoring of environmental disasters and damage from small to large regions around the globe.

Satellite Images gives state and government agencies the ability to view the damage from multiple vantage points. The spatial resolution of an image determines the ability to view individual features such as buildings and bridges. It also affects the ability to monitor and assess damage conditions, and depends on the nature of the hazard itself.

The following Images are an example of analysis;
