![]() Volcanic infrasound: When the lava lake rises up in the crater of an open vent volcano, a sign of a potential eruption, the pitch or frequency of the sounds generated by the magma tends to increase.Researchers can track indicators such as: However, there are indicators of increased volcanic activity, which researchers can use to help predict volcanic eruptions. UAVs can efficiently place sensors at long-range to minimise risk and improve the efficiency of data collection', he said.Īccording to Eric Dunham, an associate professor of Stanford University's School of Earth, energy and Environmental Sciences, 'Volcanoes are complicated and there is currently no universally applicable means of predicting eruption. ![]() 'Approaching volcanoes is hazardous and logistically challenging. 'This is an exemplary application for using UAVs (drones)', said Dr Kieran Wood, Senior Research Associate and UAV specialist in Aerospace Engineering. 'We are pushing the limits of the sensor driven low-power monitoring in this application, but that's what research is all about.'ĭue to the extreme conditions near the volcanic vents, the 'dragon eggs' are designed to be deployed by flying Unmanned Aerial Vehicles (UAVs). 'It is the first time an autonomous system using zero-power listening technology has been deployed in this kind of hostile environment', said Dr Yannick Verbelen, Research Associate in the School of Physics. The dragon eggs can report data to a base station at a safe distance of up to 10km (six miles). Thanks to this detection circuit, the eggs can remain in service for many months without depleting their energy resources. However, scientists have got around this problem by creating highly sensitive pods that can be positioned in dangerous locations to provide real-time data on eruptions For some volcanoes it is simply too dangerous for a human approach (stock image).
