Earthquakes Generate Big Heat in Super-Small Areas

In experiments mimicking the speed of earthquakes, geophysicists at Brown University detail a phenomenon known as flash heating. They report in a paper published in Science that because fault surfaces touch only at microscopic, scattered spots, these contacts are subject to intense stress and extreme heating during earthquakes, lowering their friction and thus the friction of the fault. The localized, intense heating can occur even while the temperature of the rest of the fault remains largely unaffected.
