Noise produces volcanic seismicity, akin to a drumbeat

Volcanoes are considered chaotic systems. They are difficult to model because the geophysical and chemical parameters in volcanic eruptions exhibit high levels of uncertainty. Now, Dmitri V. Alexandrov and colleagues from the Ural Federal University in Ekaterinburg, in the Russian Federation, have further extended an eruption model--previously developed by other scientists--to the friction force at work between the volcanic plug and volcanic conduit surface. The results, published in EPJ B, prov...
