A better understanding of how earthquakes occur and what happens during a rupture is important for assessing seismic risk. Small earthquakes, which are more frequent than large ones, are a tempting data set, but they're hard to study, in large part because their energy is quickly
A better understanding of how earthquakes occur and what happens during a rupture is important for assessing seismic risk. Small earthquakes, which are more frequent than large ones, are a tempting data set, but they're hard to study, in large part because their energy is quickly sapped as it travels through Earth.
