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. Mental status aside, in the past decade alone, gun-related violence accounted for the deaths of over a quarter of a million people.
The US doesnât just have a mass shooting problem â it has an enormous, multifaceted gun violence problem. Mass shootings are a growing and alarming phenomenon in the US. By a purely numerical count, the United States has seen more than 1,000 mass shootings in 1,260 days. By a stricter definition, the number is smaller but still sobering: 19 public mass shootings since the Sandy Hook elementary school massacre in December 2012. But by any definition, they make up only a tiny percentage of the overall toll of gun deaths.
