MIT geologists have quantified the energy distribution in controlled lab earthquakes, finding that about 80% of energy converts into heat, 10% causes shaking, and less than 1% fractures rocks, with the energy budget influenced by the region's deformation history, potentially aiding future seismic risk assessments.
Astrophysicists from UCLA, in collaboration with other universities, have found evidence that Alfvén waves in space plasmas accelerate ion beams, leading to the creation of small-scale acoustic waves that generate heat in the magnetosphere. Using data from NASA's Magnetospheric Multiscale Mission, the researchers confirmed theories about heat generation in the magnetosphere by showing that magnetic pressure variations in Alfvén waves are synchronized with ion density fluctuations and electric fields. Their findings, supported by simulations, provide new insights into energy transfer processes in space.
