When plate boundaries occur in continental lithosphere, deformation is spread out over a much larger area than the plate boundary, so earthquakes occur away from the plate boundary and are related to strains developed within the broader zone of deformation caused by major irregularities in the fault trace.
One study that focused on risk assessment of mental illness and violence found that the stigma attached to such illnesses prevents those who require help from actually seeking it. The study pointed out that since 1983 there have been 78 mass shootings in the U.S., resulting in 547 deaths. The mental health of the shooters was the mediaâs prime focus in each case.
