Active volcano “Santiaguito”, side volcano of the even bigger “Santa Maria”
Guatemala in Central America has three constantly active volcanos, all of which have villages near them so it is vitally important to have an early warning system for eruptions to save lives. Such systems already exist but these specific volcanos produce flows of Pyroclastic Density Current (PDC) instead of lava. The extremely dangerous PDC clouds consist of gas, rock and ash, traveling at speeds of up to 600 km/h with a heat of up to 800°C. It is therefore vital to have as much warning as possible for evacuations. A team from University College London (UCL), led by Dr Amin Amiri, is studying the PDCs and developing a radar-based early warning system with a very high level of sensitivity. The core part is a PCIe digitizer card by Spectrum Instrumentation, the model M2p.5921-x4. It is so sensitive that it can detect tiny movements at a distance of six kilometres, which is the distance that the equipment is set up from the slope of the volcano.
