The magnificent power and danger of volcanoes intrigue and fascinate Geological Researchers. They are a window into the centre of the Earth and allow researchers to better understand the Earth itself.
Through the use of a thermal imaging camera, a researcher can measure volcanic heat without the need for contact with the lava. A thermal camera is capable of recording radiated heat and displaying the thermal image and temperature reading on the display.
With the ability to measure and record active lava flows, it can also detect hot gas escaping from new cracks and analyse surface temperatures. These capabilities make the Geologist Researcher's job an easier and safer task that allows further understanding of the mechanics of volcanic activity.
A better understanding of volcanic activity will improve early warning system development that will aid the evacuation of affected areas and help save lives. However, the prediction of volcanic activity cannot always account for the unpredictability of volcanoes. For this reason equipment should always be placed at a safe distance to prevent damage.
This is also important due to a phenomenon called Fumarolic Activity. Pressurised fluids consisting of water and CO2 heat up due to volcanic warmth and the temperature of these fluids can rise to several hundreds of degrees Celsius.
It is the pressure that stops the fluids from entering the gaseous state. If this pressure changes, the fluids turn to gas very quickly, so quickly that it can cause a gas explosion. These explosions are highly dangerous and unpredictable. This is one reason for keeping equipment at safe distances.
Thermal cameras are being used instead of traditional measuring equipment, which needs to be closer to the volcano and is at great risk of being destroyed. This makes infrared cameras an ideal solution and a natural choice for Geologists, to obtain the information they need from volcanic activity.
For this type of work a sensitive camera is needed such as the Flir P660 Thermal camera or the Flir T640 Thermal camera. For information on this or any other thermal imaging camera, contact us on 0845 365 3938.
