For the first time, scientists have simulated the seismic signals that precede a volcanic eruption and created a 3-D visualization of those warning signs under controlled conditions. By performing tests on basalt rock from Sicily’s still-active volcano Mt. Etna, the team was able to record the seismic waves generated during the earthquakes that occur before volcanic eruptions.
"Nearly 500 million people live close enough to the planet’s 600 currently active volcanoes that they face serious harm, both physically and economically, should a major eruption occur. Being able to simulate the pressure conditions and events in volcanoes will greatly assist geophysicists in exploring the scientific basis for volcanic unrest. We cannot predict eruptions with total accuracy, but understanding these pre-eruption events better will help cities and towns near volcanoes know better whether they need to take the precaution of having people evacuate the area or not,” said Dr. Paul Young, Keck Chair of Seismology and Rock Mechanics as well as U of T’s Vice-President, Research.
Dr. Young noted that the information gathered through this investigation should also prove useful to other industries including mining and construction as well as to scientists studying other earth sciences phenomena
The international team of scientists involved in these ground-breaking experiments was Visiting Lassonde Institute Research Fellow, Dr. Philip Benson, who is also the Marie- Curie Research Fellow in Earth Sciences at University College London; Dr. Philip Meredith of the Rock and Ice Physics Laboratory, also from University College London; Dr.Sergio Vinciguerra of Rome’s National Geophysics and Volcano Institute; and Dr. Young. Their findings are published in a recent edition of the journal Science.For further information, please contact:

World first experiments on sensor that may revolutionise everything from medical devices to unmanned vehicles
The new sensor - capable of detecting vibrations of living cells - may revolutionise everything from medical devices to unmanned vehicles.
Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
